ARTICLE I – Meeting Basic Learning Needs 1. Every person - child, youth and adult - shall be able to benefit from educational opportunities designed to meet their basic learning needs. These needs comprise both essential learning tools (such as literacy, oral expression, numeracy, and problem solving) and the basic learning content (such as knowledge, skills, values, and attitudes) required by human beings to be able to survive, to develop their full capacities, to live and work in dignity, to participate fully in development, to improve the quality of their lives, to make informed decisions, and to continue learning. The scope of basic learning needs and how they should be met varies with individual countries and cultures, and inevitably, changes with the passage of time.2. The satisfaction of these needs empowers individuals in any society and confers upon them a responsibility to respect and build upon their collective cultural, linguistic and spiritual heritage, to promote the education of others, to further the cause of social justice, to achieve environmental protection, to be tolerant towards social, political and religious systems which differ from their own, ensuring that commonly accepted humanistic values and human rights are upheld, and to work for international peace and solidarity in an interdependent world.3. Another and no less fundamental aim of educational development is the transmission and enrichment of common cultural and moral values. It is in these values that the individual and society find their identity and worth.4. Basic education is more than an end in itself. It is the foundation for lifelong learning and human development on which countries may build, systematically, further levels and types of education and training. :ARTICLE II – Shaping the VisionT o serve the basic learning needs of all requires more than a recommitment to basic education as it now exists. What is needed is an "expanded vision" that surpasses present resource levels, institutional structures, curricula, and conventional delivery systems while building on the best in current practices. New possibilities exist today which result from the convergence of the increase in information and the unprecedented capacity to communicate. We must seize them with creativity and a determination for increased effectiveness. As elaborated in Articles III-VII, the expanded vision encompasses:⏹Universalizing access and promotingequity;⏹Focusing on learning;⏹Broadening the means and scope ofbasic education;⏹Enhancing the environment for learning;⏹Strengthening partnerships.The realization of an enormous potential for human progress and empowerment is contingent upon whether people can be enabled to acquire the education and the start needed to tap into the ever-expanding pool of relevant knowledge and the new means for sharing this knowledge.ARTICLE III – Universalizing Access and Promoting Equity1. Basic education should be provided to allchildren, youth and adults. To this end, basic education services of quality should be expanded and consistent measures must be taken to reduce disparities.2. For basic education to be equitable, all children, youth and adults must be given the opportunity to achieve and maintain an acceptable level of learning.3. The most urgent priority is to ensure access to, and improve the quality of, education for girls and women, and to remove every obstacle that hampers their active participation. All gender stereotyping in education should be eliminated.4. An active commitment must be made to removing educational disparities. Underserved groups: the poor; street and working children; rural and remote populations; nomads and migrant workers; indigenous peoples; ethnic, racial, and linguistic minorities; refugees; those displaced by war; and people under occupation, should not suffer any discrimination in access to learning opportunities.5. The learning needs of the disabled demand special attention. Steps need to be taken to provide equal access to education to every category of disabled persons as an integral part of the education system.ARTICLE IV – Focusing on LearningWhether or not expanded educational opportunities will translate into meaningful development - for an individual or for society - depends ultimately on whether people actually learn as a result of those opportunities, i.e., whether they incorporate useful knowledge, reasoning ability, skills, and values. The focus of basic education must, therefore, be on actual learning acquisition and outcome, rather than exclusively upon enrolment, continued participation in organized programmes and completion of certification requirements. Active and participatory approaches are particularly valuable in assuring learning acquisition and allowing learners to reach their fullest potential. It is, therefore, necessary to define acceptable levels of learning acquisition for educational programmes and to improve and apply systems of assessing learning achievement. ARTICLE V – Broadening the Means and Sope of Basic Education The diversity, complexity, and changing nature of basic learning needs of children, youth and adults necessitates broadening and constantly redefining the scope of basic education to include the following components:⏹Learning begins at birth. This calls forearly childhood care and initial education .These can be provided througharrangements involving families,communities, or institutional programmes,as appropriate.⏹The main delivery system for the basiceducation of children outside the family isprimary schooling. Primary educationmust be universal, ensure that the basiclearning needs of all children are satisfied, and take into account the culture, needs,and opportunities of the community.Supplementary alternative programmescan help meet the basic learning needs ofchildren with limited or no access toformal schooling, provided that they sharethe same standards of learning applied toschools, and are adequately supported.⏹The basic learning needs of youth andadults are diverse and should be metthrough a variety of delivery systems.Literacy programmes are indispensablebecause literacy is a necessary skill initself and the foundation of other life skills.Literacy in the mother-tongue strengthenscultural identity and heritage. Other needscan be served by: skills training,apprenticeships, and formal andnon-formal education programmes inhealth, nutrition, population, agriculturaltechniques, the environment, science,technology, family life, including fertilityawareness, and other societal issues.⏹All available instruments and channels ofinformation, communications, and socialaction could be used to help conveyessential knowledge and inform andeducate people on social issues. Inaddition to the traditional means, libraries,television, radio and other media can bemobilized to realize their potentialtowards meeting basic education needsof all.These components should constitute an integrated system - complementary, mutually reinforcing, and of comparable standards, and they should contribute to creating anddeveloping possibilities for lifelong learning.ARTICLE VI – Enhancing the Environment for LearningLearning does not take place in isolation. Societies, therefore, must ensure that all learners receive the nutrition, health care, and general physical and emotional support they need in order to participate actively in and benefit from their education. Knowledge and skills that will enhance the learning environment of children should be integrated into community learning programmes for adults. The education of children and their parents or other caretakers is mutually supportive and this interaction should be used to create, for all, a learning environment of vibrancy and warmth.ARTICLE VII – Strengthening PartnershipsNational, regional, and local educational authorities have a unique obligation to provide basic education for all, but they cannot be expected to supply every human, financial or organizational requirement for this task…ARTICLE VIII – Developing a Supportive Policy Context1. Supportive policies in the social, cultural, and economic sectors are required in order to realize the full provision and utilization of basic education for individual and societal improvement. The provision of basic education for all depends on political commitment and political will backed by appropriate fiscal measures and reinforced by educational policy reforms and institutional strengthening. Suitable economic, trade, labor, employment and health policies will enhance learners' incentives and contributions to societal development.2. Societies should also insure a strong intellectual and scientific environment for basic education. This implies improving higher education and developing scientific research. Close contact with contemporary technological and scientific knowledge should be possible at every level of education.ARTICLE IX – Mobilizing Resources1. If the basic learning needs of all are to be met through a much broader scope of action than in the past, it will be essential to mobilize existing and new financial and human resources, public, private and voluntary. All of society has a contribution to make, recognizing that time, energy and funding directed to basic education are perhaps the most profound investment in people and in the future of a country which can be made.2. Enlarged public-sector support means drawing on the resources of all the government agencies responsible for human development, through increased absolute and proportional allocations to basic education services with the clear recognition of competing claims on national resources of which education is an important one, but not the only one…ARTICLE X – Strengthening International Solidarity1. Meeting basic learning needs constitutes a common and universal human responsibility. It requires international solidarity and equitable and fair economic relations in order to redress existing economic disparities. All nations have valuable knowledge and experiences to share for designing effective educational policies and programmes.2. Substantial and long-term increases in resources for basic education will be needed. The world community, including intergovernmental agencies and institutions, has an urgent responsibility to alleviate the constraints that prevent some countries from achieving the goal of education for all. It will mean the adoption of measures that augment the national budgets of the poorest countries or serve to relieve heavy debt burdens…。

2024年教师资格考试高中英语学科知识与教学能力自测试题及解答参考一、单项选择题(本大题有30小题,每小题2分,共60分)1、What is the main purpose of the following sentence in a high school English text?“The moon is a silent witness to the stars’ eternal dance.”A)To describe the physical appearance of the moon and stars.B)To emphasize the beauty of the night sky.C)To convey the idea that the stars are eternal.D)To introduce a metaphorical comparison between the moon and stars.答案:D解析:The sentence uses a metaphorical comparison (“silent witness to the stars’ eternal dance”) to convey a deeper meaning, suggesting that the moon is like a silent observer to the timeless movement of the stars. Therefore, the main purpose is to introduce this metaphorical comparison, making option D the correct answer. The other options are more focused on the literal description or the beauty of the night sky, which are not the primary purposes of the sentence in this context.2、In the following dialogue, which word is most likely used as a transitional word that helps the conversation flow smoothly?A)“However”B)“Therefore”C)“Moreover”D)“Nonetheless”答案:A解析:The word “however” is commonly used as a transitional word that introduces a contrast or a contradiction to the previous statement. It helps to maintain a smooth flow of the conversation by indicating a change in direction or a contrasting idea. The other options—B) “Therefore,” C) “Moreover,” and D) “Nonetheless”—are all used to introduce reasons, additional information, or a similar idea, which are not transitional in the same way. Thus, option A is the correct choice.3、The following sentence is an example of which grammatical structure?A. Active voiceB. Passive voiceC. Future perfect tenseD. Present perfect continuous tenseAnswer: B. Passive voiceExplanation: The sentence “The book was written by the author” is in the passive voice, where the subject “the book” receives the action of the verb “was written.”4、Which of the following words is a synonym for “motivate”?A. EncourageB. DiscourageC. InhibitD. PreventAnswer: A. EncourageExplanation: “Motivate” means to inspire or give a reason to act. The word “encourage” also means to inspire or give a reason to act, making it the closest synonym. The other options, “discourage,” “inhibit,” and “prevent,” all imply a negative or opposite action.5、What is the main purpose of using the “talking sticks” in the teaching of English?A. To encourage students to speak more freely.B. To improve students’ listening skills.C. To focus on the grammatical structures.D. To develop students’ writing abilities.Answer: AExplanation: The “talking sticks” are often used in English teaching to provide a non-threatening environment where students can speak without fear of being interrupted or criticized. This method helps to encourage students to speak more freely, fostering better communication skills and confidence in using the language. The other options are not the primary focus of using “talking sticks.”6、In the context of English teaching, which of the following techniques is most effective for promoting critical thinking among students?A. Repetition of vocabulary.B. Direct instruction on grammatical rules.C. Guided discovery learning.D. rote memorization of sentence structures.Answer: CExplanation: Guided discovery learning is a technique that encourages students to explore and understand concepts on their own, with the teacher guiding the process. This approach is most effective for promoting critical thinking because it allows students to engage with the material actively and develop their problem-solving skills. Repetition, direct instruction, and rote memorization are more passive learning methods that may not promote critical thinking as effectively.7、In the following sentence, which word is a demonstrative pronoun?A. This is my book.B. That is his pen.C. These are their keys.D. Those are yours.Answer: B. That is his pen.Explanation: The word “That” is a demonstrative pronoun, referring to a specific object mentioned earlier in the conversation or context.8、Which of the following sentence structures is used to show a contrast between two things or ideas?A.

Which of the following would be the most appropriate strategy to assess the students’ understanding of the new concept?A)Group workB)QuizC)LectureD)Role-playAnswer: D) Role-playExplanation: Role-play is an effective strategy for assessing students’ understanding because it allows them to engage actively in the learning process, practice the new language, and demonstrate their comprehension in a real-life context.10、In order to differentiate instruction for diverse learners in a high school English class, the teacher should consider which of the following approaches?A)Using the same textbook and teaching methods for all studentsB)Providing additional homework for students who are strugglingC)Offering a variety of activities that cater to different learning stylesD)Restricting class discussions to only those students who volunteerAnswer: C) Offering a variety of activities that cater to different learning stylesExplanation: Catering to different learning styles ensures that all students have the opportunity to engage with the material in a way that best suits their individual needs, which can lead to better comprehension and retention of the material.11.The teacher is using a variety of teaching methods to engage the students in learning. Which of the following is NOT an effective method of teaching in this context?A. Role-playingB. Group discussionsC. LecturingD. Project-based learningAnswer: CExplanation: While lecturing can be effective in certain situations, it is generally not the most engaging method for high school students. Role-playing, group discussions, and project-based learning are interactive and encourage student participation, making them more effective in engaging students in learning.12.In order to assess students’ understanding of the past tense in English,a teacher uses a multiple-choice question.

By learning about prefixes, suffixes, and root words, students can make educated guesses about the meaning of new words, which can improve their vocabulary acquisition. Using flashcards and games can also be helpful, but explaining the meaning of words in their native language may not always be effective, as it could hinder the development of their English vocabulary.25.What is the primary purpose of the following sentence in a high school English lesson?A) To provide a direct definition of a key term.B) To encourage students to predict the content of a text.C) To summarize the main points of a previously discussed topic.D) To challenge students with a complex grammatical structure.Answer: B) To encourage students to predict the content of a text.Explanation: The primary purpose of using a sentence to encourage students to predict the content of a text is to engage them in active learning and critical thinking. This approach helps students develop their inferencing skills and anticipate what might be coming next in the lesson or text.26.In a high school English class, which of the following activities is most likely to promote students’ ability to analyze and evaluate literary texts?A)Completing a multiple-choice quiz about the plot of a novel.B)Participating in a group discussion about the themes of a play.C)Watching a film adaptation of a short story and answering comprehension questions.D)Translating a passage from English to their native language.Answer: B) Participating in a group discussion about the themes of a play.Explanation: Group discussions about themes in a play encourage students to engage deeply with the text, share their interpretations, and evaluate different perspectives. This activity fosters critical thinking and analytical skills as students discuss the underlying messages and how they are conveyed through the play’s characters and plot.27、Which of the following sentences correctly uses the subjunctive mood?A) If I was you, I would take the job.B) I suggest that she will study harder.C) It is essential that he finish his homework before playing.D) If she would have enough money, she would buy a car.Correct Answer: C) It is essential that he finish his homework before playing.Explanation:The correct use of the subjunctive mood involves changes to the verb form to express wishes, suggestions, or demands. Option C uses the subjunctive correctly by employing the base form of the verb “finish” after “that he,” which follows the word “essential.”28、Identify the type of sentence structure used in the following sentence: “While she was reading a book, her brother was playing video games.”A) Simple sentenceB) Compound sentenceC) Complex sentenceD) Compound-complex sentenceCorrect Answer: C) Complex sentenceExplanation:A complex sentence contains one independent clause and at least one dependent clause. In this example, “her brother was playing video games” is the independent clause, and “while she was reading a book” is the dependent clause. The sentence structure fits the definition of a complex sentence because it has both an independent and a dependent clause joined together.29.In the following sentence, which word is used as a demonstrative pronoun?A. This is the book that I need.B. These are the books which I need.C. That is the book that I need.D. Those are the books which I need.Answer: CExplanation: The word “that” in option C is used as a demonstrative pronoun, referring to a specific book mentioned earlier in the context. Options A, B, and D use relative pronouns (“which”) to introduce relative clauses, not demonstrative pronouns.30.Choose the sentence that correctly uses the past participle form of the verb “visit” in a passive voice construction.A. The museum was visited by the tourists yesterday.B. The tourists visited the museum yesterday.C. Yesterday, the tourists visited the museum.D. The museum was visited on by the tourists yesterday.Answer: AExplanation: In a passive voice construction, the past participle form of the verb follows the auxiliary verb “was.” Option A correctly uses “was visited” as the past participle form in the passive voice. Options B and C are in the active voice, and option D incorrectly uses “on” with “visited.”二、简答题(20分)Section II: Short Answer QuestionsQuestion 1:Explain the concept of “Communicative Language Teaching” (CLT) anddiscuss how it can be effectively implemented in a high school English classroom. Provide at least three practical strategies that a teacher could use to promote communicative competence among students.Answer:Explanation of Communicative Language Teaching (CLT):Communicative Language Teaching (CLT) is an approach to language teaching that emphasizes interaction as both the means and the ultimate goal of learning a language. The core principle of CLT is that successful language learning comes through having to communicate real meaning. In other words, learners learn a language by using it for authentic communication rather than by simply studying its structure or rules. This approach focuses on all four language skills—listening, speaking, reading, and writing—and aims to develop the learner’s ability to use the target language fluently and accurately in real-life situations.Implementation in a High School Classroom:To effectively implement CLT in a high school English classroom, teachers should focus on creating a student-centered environment where students are encouraged to interact with each other and with the teacher in the target language. Here are three practical strategies:1.Role-Playing Activities: Engage students in role-playing scenarios that require them to use the target language to solve problems, negotiate, or exchange information. For example, students might act out a scenario at a restaurant, where they need to order food, make requests, and handle misunderstandings. Such activities not only make learning fun but alsohelp students practice using language in context.2.Group Discussions and Projects: Organize group discussions on topics relevant to the students’ interests or current events. Encourage students to express their opinions, agree or disagree, and support their points with evidence. Group projects, such as preparing a presentation on a topic of interest, can further enhance students’ collaborative and communicative skills.3.Authentic Materials and Real-World Tasks: Incorporate authentic materials like news articles, podcasts, videos, and social media into the lessons. Assign tasks that require students to interpret and respond to these materials, which can include summarizing, debating, or creating follow-up content. This helps bridge the gap between the classroom and the real world, making language learning more meaningful and engaging.By integrating these strategies, teachers can foster an environment where students actively use the English language, thereby enhancing their communicative competence and overall language proficiency.Analysis:This answer provides a clear definition of CLT and highlights its importance in language education. It then offers concrete examples of how to apply CLT principles in a high school setting, focusing on fostering interactive and meaningful communication. The suggested strategies are designed to engage students in active language use, reflecting the key tenets of CLT. Through these methods, students not only learn about the language but also gain experiencein using it, which is essential for developing true communicative competence.三、教学情境分析题(30分)Question 3: Teaching Situation AnalysisScenario:Mr. Smith, a high school English teacher, is preparing a lesson on “The Great Gatsby” by F. Scott Fitzgerald. The students are in the 11th grade and have already read the novel. However, Mr. Smith has noticed that the students seem uninterested in the lesson, and their participation in class discussions is low. He would like to engage his students more effectively.Task:Analyze the given teaching situation and suggest strategies that Mr. Smith can use to improve student engagement and participation in the lesson.Answer:To improve student engagement and participation in the lesson on “The Great Gatsby,” Mr.Smith can employ the following strategies:1.Interactive Discussion: Mr.Smith can organize an interactive discussion session by asking thought-provoking questions related to the novel’s themes, characters, and symbols. This will encourage students to express their opinions and engage in meaningful discussions.2.Role Play: Assigning students to characters in “The Great Gatsby” and having them perform scenes from the novel can help students connect with the characters on a deeper level. This activity will make the lesson more dynamicand interesting.3.Visual Aids: Incorporating visual aids such as posters, maps, and time lines can help students visualize the historical context of the novel and understand the setting better.4.Group Work: Divide the class into small groups and assign each group a specific aspect of the novel to research. They can then present their findings to the class, fostering teamwork and collaboration.5.Creative Projects: Encourage students to create their own projects based on “The Great Gatsby,” such as writing a short story inspired by the novel or designing a poster advertising a fictional movie adaptation of the book.6.Incorporate Technology: Use technology tools such as educational apps, online quizzes, and video clips to make the lesson more engaging. This will cater to different learning styles and keep students interested.Explanation:Mr. Smith’s approach to teaching “The Great Gatsby” should focus on student-centered activities that encourage active participation. By incorporating interactive discussions, role play, visual aids, group work, creative projects, and technology, Mr. Smith can create a more engaging and dynamic classroom environment, thereby enhancing student interest and participation in the lesson.四、教学设计题(40分)Section IV: Teaching Design (30 points)Question 1:You are required to design a lesson plan for a high school English class based on the following passage:Text Title: “The Impact of Social Media on Communication”Excerpt from the Text:“Social media has revolutionized the way we communicate.

Volunteer and Staff Management: Recruiting, training, and managing a dedicated team of volunteers and staff to assist with the various aspects of the competition, from registration and logistics to judging and event coordination.8. Sponsorship and Funding: Securing the necessary financial resources through sponsorships, grants, or other funding sources to cover the costs of organizing and running the competition.Effective communication and coordination among all the stakeholders involved, from the organizing committee to the participants and sponsors, is crucial to the success of the competitionplan.Promoting and Executing the CompetitionWith the comprehensive plan in place, the next step is to promote the competition and execute the event.

From small businesses to large corporations, employers are recognizing that team collaboration isessential for success. Here are a few reasons why:1. Diverse PerspectivesCollaboration introduces a variety of opinions and approaches to problem-solving. When working in a team with individuals from different backgrounds and experiences, new ideas and fresh thinking emerge. By combining diverse perspectives, a more comprehensive solution can be reached.2. Enhanced CreativityWhen individuals work together, new ideas are generated and brainstorming is encouraged. Collaborative environments inspire creativity and innovation as members build on each other's ideas and challenge each other's thinking. This allows a team to develop more creative solutions than would have been possible alone.3. Better Time ManagementCollaborating in a team allows for the delegation of tasks, so each member can focus on areas where they are most skilled. This not only improves efficiency, but also results in a higher quality output. Plus, teamwork promotes accountability and motivates individuals to complete tasks on time.4. Improved Communication SkillsCollaborating in a team requires constant communication, which helps to improve communication skills. Members learn to listen actively, express themselves clearly, and give constructive feedback. Good communication skills contributeto better interpersonal relationships and create a positive work environment.5. Greater ProductivityStudies have shown that teamwork increases productivity.

SLA 期末考试提纲Week 9Chapter 1 Introducing Second Language AcquisitionChapter 2 Foundations of Second Language AcquisitionPART ONE: Definition:1.Second Language Acquisition (SLA): a term that refers both to the study of individuals and groups who arelearning a language subsequent to learning their first one as young children, and to the process of learning that language.2.Formal L2 learning: instructed learning that takes place in classrooms.rmal L2 learning: SLA that takes place in naturalistic contexts.4.First language/native language/mother tongue (L1): A language that is acquired naturally in early childhood,usually because it is the primary language of a child‘s family. A child who grows up in a multilingual setting may have more than one ―first‖ language.5.Second language (L2):: A language that is acquired naturally in early childhood, usually because it is the primarylanguage of a child‘s family. A child who grows up in a multilingual setting may have more than one ―first‖ language.6.Target language: The language that is the aim or goal of learning.7.Foreign language: A second language that is not widely used in the learners‘ immediate social context, but ratherone that might be used for future travel or other cross-cultural communication situations, or one that might be studied be studied as a curricular requirement or elective in school with no immediate or necessary practical application.8.Library language: A second language that functions as a tool for further learning, especially when books andjournals in a desired field of study are not commonly published in the learner‘s L1.9.Auxiliary language: A second language that learners need to know for some official functions in their immediatesociopolitical setting. Or that they will need for purposes of wider communication, although their first language serves most other needs in their lives.10.Linguistic competence: The underlying knowledge that speakers/hearers have of a language. Chomskydistinguishes this from linguistic performance.11.Linguistic performance: The use of language knowledge in actual production.municative competence: A basic tenet (原则、信条、教条) of sociolinguistics defined as ―what a speakerneeds to know to communicate appropriately within a particular language community‖ (Saville-Troike 2003) 13.Pragmatic competence: Knowledge that people must have in order to interpret and convey meaning withincommunicative situations.14.Multilingualism: The ability to use more than one language.15.Monolingualism: The ability to use only one language.16.Simultaneous multilingualism: Ability to use more than one language that were acquired during early childhood.17.Sequential multilingualism: Ability to use one or more languages that were learned after L1 had already beenestablished.18.Innate capacity: A natur al ability, usually referring to children‘s natural ability to learn or acquire language.19.Child grammar: Grammar of children at different maturational levels that is systematic in terms of production andcomprehension.20.Initial state: The starting point for language acquisition; it is thought to include the underlying knowledge aboutlanguage structures and principles that are in learners‘ heads at the very start of L1 or L2 acquisition.21.Intermediate state: It includes the maturational changes which take pla ce in ―child grammar‖, and the L2developmental sequence which is known as learner language.22.Final state: The outcome of L1 and L2 leaning, also known as the stable state of adult grammar.23.Positive transfer: Appropriate incorporation of an L1 structure or rule in L2 structure.24.Negative transfer: Inappropriate influence of an L1 structure or rule on L2 use. Also called interference.25.Poverty-of-the-stimulus: The argument that because language input to children is impoverished and they stillacquire L1, there must be an innate capacity for L1 acquisition.26.Structuralism: The dominant linguistic model of the 1950s, which emphasized the description of different levels ofproduction in speech.27.Phonology: The sound systems of different languages and the study of such systems generally.28.Syntax: The linguistic system of grammatical relationships of words within sentences, such as ordering andagreement.29.Semantics: The linguistic study of meaning.30.Lexicon: The component of language that is concerned with words and their meanings.31.Behaviorism: The most influential cognitive framework applied to language learning in the 1950s. It claims thatlearning is the result of habit formation.32.Audiolingual method: An approach to language teaching that emphasizes repetition and habit formation. Thisapproach was widely practiced in much of the world until at least the 1980s.33.Transformational-Generative Grammar: The first linguistic framework with an internal focus, whichrevolutionized linguistic theory and had profound effect on both the study of first and second languages. Chomsky argued effectively that the behaviorist theory of language acquisition is wrong because it cannot explain the creative aspects of linguistic ability. Instead, humans must have some innate capacity for language.34.Principles and Parameters (model): The internally focused linguistic framework that followed Chomsky‘sTransformational-Generative Grammar. It revised specifications of what constitutes innate capacity to include more abstract notions of general principles and constraints common to human language as part of a Universal Grammar.35.Minimalist program: The internally focused linguistic framework that followed Chomsky‘s Principles andParameters model.This framework adds distinctions between lexical and functional category development, as well as more emphasis on the acquisition of feature specification as a part of lexical knowledge.36.Functionalism: A linguistic framework with an external focus that dates back to the early twentieth century andhas its roots in the Prague School (布拉格学派) of Eastern Europe. It emphasizes the information content of utterances and considers language primarily as a system of communication. Functionalist approaches have largely dominated European study of SLA and are widely followed elsewhere in the world.37.Neurolinguistics: The study of the location and representation of language in the brain, of interest to biologists andpsychologists since the nineteenth century and one of the first fields to influence cognitive perspectives on SLA when systematic study began in 1960s.38.Critical period: The limited number of years during which normal L1 acquisition is possible.39.Critical Period Hypothesis: The claim that children have only a limited number of years during which they canacquire their L1 flawlessly; if they suffered brain damage to the language areas, brain plasticity in childhood would allow other areas of the brain to take over the language functions of the damaged areas, but beyond a certain age, normal language development would not be possible. This concept is commonly extended to SLA as well, in the claim that only children are likely to achieve native or near-native proficiency in L2.rmation processing (IP): A cognitive framework which assumes that SLA (like learning of other complexdomains) proceeds from controlled to automatic processing and involves progressive reorganization of knowledge.41.Connectionism: A cognitive framework for explaining learning processes, beginning in the 1980s and becomingincreasingly influential. It assumes that SLA results from increasing strength of associations between stimuli and responses.42.Variation theory: A microsocial framework applied to SLA that explores systematic differences in learnerproduction which depend on contexts of use.43.Accommodation theory: A framework for study of SLA that is based on the notion that speakers usuallyunconsciously change their pronunciation and even the grammatical complexity of sentences they use to sound more like whomever they are talking to.44.Sociocultural theory (SCT): An approach established by Vygotsky which claims that interaction not onlyfacilitates language learning but is a causative force in acquisition. Further, all of learning is seen as essentially a social process which is grounded in sociocultural settings.45.Ethnography(人种论、民族志) of communication: A framework for analysis of language and its functions thatwas established by Hymes(1966). It relates language use to broader social and cultural contexts, and applies ethnographic methods of data collection and interpretation to study of language acquisition and use.46.Acculturation(文化适应): Learning the culture of the L2 community and adapting to those values and behaviorpatterns.47.Acculturation Model/Theory: Schumann‘s (1978) theory that identifies gro up factors such as identity and statuswhich determine social and psychological distance between learner and target language populations. He claims these influence outcomes of SLA.48.Social psychology: A societal approach in research and theory that allows exploration of issues such as howidentity, status, and values influence L2 outcomes and why. It has disciplinary ties to both psychological and social perspectives.PART TWO: Short & Long answers:Chapter 11.What are the similarities and differences between linguists, psycholinguist, sociolinguists and socialpsycholinguists? P3(1)Linguists emphasize the characteristics of the differences and similarities in the languages that are being learned, and the linguistic competence (underlying knowledge) and linguistic performance (actual production) of learners at various stages of acquisition.(2)Psychologists and psycholinguists emphasize the mental or cognitive processes involved in acquisition, and the representation of languages in the brain.(3)Sociolinguists emphasize variability in learner linguistic performance, and extend the scope of study to communicative competence (underlying knowledge that additionally accounts for language use, or pragmatic competence).(4)Social psychologists emphasize group-related phenomena, such as identity and social motivation, and the interactional and larger social contexts of learning.2.What are the differences between second language, foreign language, library language and auxiliarylanguage? P4(1)A second language is typically an official or societally dominant language needed for education, employment, and other basic purposes. It is often acquired by minority group members or immigrants who speak another language natively. In this more restricted sense, the term is contrasted with other terms in this list.(2)A foreign language is one not widely used in the learners' immediate social context which might be used for future travel or other cross-cultural communication situations, or studied as a curricular requirement or elective in school, but with no immediate or necessary practical application.(3)A library language is one which functions primarily as a tool for future learning through reading, especially when books or journals in a desired field of study are not commonly published in the learners' native tongue.(4)An auxiliary language is one which learners need to know for some official functions in their immediate political setting, or will need for purposes of wider communication, although their first language serves most other needs in their lives.3.Why are some learners more (or less) successful than other? P5The intriguing question of why some L2 learners are more successful than others requires us to unpack the broad label ―learners‖ for some dimensions of disc ussion. Linguistics may distinguish categories of learners defined by the identity and relationship of their L1 and L2; psycholinguists may make distinctions based on individual aptitude for L2 learning, personality factors, types and strength of motivation, and different learning strategies;sociolinguists may distinguish among learners with regard to social, economic, and political differences and learner experiences in negotiated interaction; and social psychologists may categorize learners according to aspects of their group identity and attitudes toward target language speakers or toward L2 learning itself.Chapter21.List at least five possible motivations for learning a second language at an older age. P10The motivation may arise from a variety of conditions, including the following:●Invasion or conquest of one‘s country by speakers of another language;● A need or desire to contact speakers of other languages in economic or other specific domains;●Immigration to a country where use of a language other than one's L1 is required;●Adoption of religious beliefs and practices which involve use of another language;● A need or desire to pursue educational experiences where access requires proficiency in another language;● A desire for occupational or social advancement which is furthered by knowledge of another language;●An interest in knowing more about peoples of other cultures and having access to their technologies orliteratures.2.What are the two main factors that influence the language learning? P13(1)The role of natural ability: Humans are born with a natural ability or innate capacity to learn language.(2)The role of social experience: Not all of L1 acquisition can be attributed to innate ability, for language-specific learning also plays a crucial role. Even if the universal properties of language arepreprogrammed in children, they must learn all of those features which distinguish their L1 from all other possible human languages. Children will never acquire such language-specific knowledge unless that language is used with them and around them, and they will learn to use only the language(s) used around them, no matter what their linguistic heritage. American-born children of Korean or Greek ancestry will never learn the language of their grandparents if only English surrounds them, for instance, and they will find their ancestral language just as hard to learn as any other English speakers do if they attempt to learn it as an adult. Appropriate social experience, including L1 input and interaction, is thus a necessary condition for acquisition.3.What is the initial state of language development for L1 and L2 respectively? P17-18The initial state of L1 learning is composed solely of an innate capacity for language acquisition which may or may not continue to be available for L2, or may be available only in some limited ways. The initial state for L2 learning, on the other hand, has resources of L1 competence, world knowledge, and established skills for interaction, which can be both an asset and an impediment.4.How does intermediate states process? P18-19The cross-linguistic influence, or transfer of prior knowledge from L1 to L2, is one of the processes that is involved in interlanguage development. Two major types of transfer which occur are: (1) positive transfer, when an L1 structure or rule is used in an L2 utterance and that use is appropriate or ―correct‖ in the L2; and (2) negative transfer (or interference), when an L1 structure or rule is used in an L2 utterance and that use is inappropriate and c onsidered an ―error‖.5.What is a necessary condition for language learning (L1 or L2)? P20Language input to the learner is absolutely necessary for either L1 or L2 learning to take place. Children additionally require interaction with other people for L1 learning to occur. It is possible for some individuals to reach a fairly high level of proficiency in L2 even if they have input only from such generally non-reciprocal sources as radio, television, or written text.6.What is a facilitating condition for language learning? P20While L1 learning by children occurs without instruction, and while the rate of L1 development is not significantly influenced by correction of immature forms or by degree of motivation to speak, both rate and ultimate level of development in L2 can be facilitated or inhabited by many social and individual factors, such as(1) feedback, including correction of L2 learners' errors; (2) aptitude, including memory capacity and analyticability; (3) motivation, or need and desire to learn; (4) instruction, or explicit teaching in school settings.7.Give at least 2 reasons that many scientists believe in some innate capacity for language. P21-24The notion that innate linguistic knowledge must underlie language acquisition was prominently espoused by Noam Chomsky. This view has been supported by arguments such as the following:(1)Children‘s knowledge of language goes beyond what could be learned from the input they receive: Childrenoften hear incomplete or ungrammatical utterances along with grammatical input, and yet they are somehow able to filter the language they hear so that the ungrammatical input is not incorporated into their L1 system.Further, children are commonly recipients of simplified input from adults, which does not include data for all of the complexities which are within their linguistic competence. In addition, children hear only a finite subset of possible grammatical sentences, and yet they are able to abstract general principles and constraints which allow them to interpret and produce an infinite number of sentences which they have never heard before.(2)Constraints and principles cannot be learned: Children‘s access to general constraints and principles whichgovern language could account for the relatively short time it takes for the L1 grammar to emerge, and for the fact that it does so systematically and without any ―wild‖ divergences. This could be so because innate principles lead children to organize the input they receive only in certain ways and not others. In addition to the lack of negative evidence , constraints and principles cannot be learnt in part because children acquire a first language at an age when such abstractions are beyond their comprehension; constraints and principles are thus outside the realm of learning process which are related to general intelligence.(3)Universal patterns of development cannot be explained by language-specific input: In spite of the surfacedifferences in input, there are similar patterns in child acquisition of any language in the world. The extent of this similarity suggests that language universals are not only constructs derived from sophisticated theories and analyses by linguists, but also innate representations in every young child‘s mind.8.Linguists have taken an internal and/or external focus to the study of language acquisition. What is thedifference between the two? P25-26Internal focus emphasizes that children begin with an innate capacity which is biologically endowed, as well as the acquisition of feature specification as a part of lexical knowledge; while external focus emphasizes the information content of utterances, and considers language primarily as a system of communication.9.What are the two main factors for learning process in the study of SLA from a psychological perspective?P26-27(1) Information Processing, which assumes that L2 is a highly complex skill, and that learning L2 is notessentially unlike learning other highly complex skills. Processing itself is believed to cause learning;(2) Connectionism, which does not consider language learning to involve either innate knowledge or abstractionof rules and principles, but rather to result from increasing strength of associations (connections) between stimuli and responses.10.What are the two foci for the study of SLA from the social perspective? P27(1) Microsocial focus: the concerns within the microsocial focus relate to language acquisition and use inimmediate social contexts of production, interpretation, and interaction. (2) Macrosocial focus: the concerns of the macrosocial focus relate language acquisition and use to broader ecological contexts, including cultural, political, and educational settings.Week10Chapter 5 Social contexts of Second Language AcquisitionPART ONE: Definitionmunicative compet ence: A basic tenet of sociolinguistics defined as ―what a speaker needs to know tocommunicate appropriately within a particular language community‖(Saville-Troike 2003)nguage community: A group of people who share knowledge of a common language to at least some extent.3.Foreigner talk: Speech from L1 speakers addressed to L2 learners that differs in systematic ways from languageaddressed to native or very fluent speakers.4.Direct Correction: Explicit statements about incorrect language use.5.Indirect correction: Implicit feedback about inappropriate language use, such as clarification requests when thelistener has actually understood an utterance.6.Interaction Hypothesis: The claim that modifications and collaborative efforts which take place in social interationfacilitate SLA because they contribute to the accessibility of input for mental processing.7.Symbolic mediation: A link between a person‘s current mental state and higher order functions that is providedprimarily by language; considered the usual route to learning (of language, and of learning in general).

The differences of the competence between native speakers and nonative speakers include structural differences in the linguisitc system, different rules for usage in writing or conversation, and even somewhat divergent meanings for the ―same‖ lexical forms. Further, a multilingual speaker‘s total communicative competence differs from that of a monolingual in including knowledge of rules for the appropriate choice of language and for switching between languages, given a particular social context and communicative purpose.2.what are the microsocial factors that affect SLA? P101-102a) L2 variation b) input and interaction c) interaction as the genesis of language3.What is the difference between linguistic & communicative competence (CC)?Linguistic competence- It was defined in 1965 by Chomsky as a speaker's underlying ability to produce grammatically correct expressions. Linguistic competence refers to knowledge of language. Theoretical linguistics primarily studies linguistic competence: knowledge of a language possessed by ―an ideal speak-listener‖.Communicative competence- It is a term in linguistics which refers to ―what a speaker needs to know to communicate appropriately within a particular language community‖, such as a language user's grammatical knowledge of syntax ,morphology , phonology and the like, as well as social knowledge about how and when to use utterances appropriately.4.Why is CC in L1 different from L2?L1 learning for children is an integral part of their sociolization into their native language community. L2 learning may be part of second culture learning and adaptation, but the relationship of SLA to social and cultural learning differs greatly with circumstances.5.What is Accommodation Theory? How does this explain L2 variation?Accommodation theory: Speakers (usually unconsciously) change their pronunciation and even the grammatical complexity of sentences they use to sound more like whomever they are talking to. This accounts in part for why native speakers tend to simply their language when they are talking to a L2 learner who is not fluent, and why L2 learners may acquire somewhat different varieties of the target language when they have different friends.6.Discuss the importance of input & interaction for L2 learning. How could this affect the feedback providedto students?ⅰ. a) From the perspective of linguistic approaches: (1) behaviorist: they consider input to form the necessary stimuli and feedback which learners respond to and imitate; (2) Universal Grammar: they consider exposure to input a necessary trigger for activating internal mechanisms; (3) Monitor Model: consider comprehensible input not only necessary but sufficient in itself to account for SLA;b) From the perspective of psychological approaches: (1) IP framework: consider input which is attended to as essential data for all stages of language processing; (2) connectionist framework: consider the quantity or frequency of input structures to largely determine acquisitional sequencing;c) From the perspective of social approaches: interaction is generally seen as essential in providing learners with the quantity and quality of external linguistic input which is required for internal processing.ⅱ. Other types of interaction which can enhance SLA include feedback from NSs which makes NNs aware that their usage is not acceptable in some way, and which provides a model for ―correctness‖. Whil e children rarely receive such negative evidence in L1, and don‘t require it to achieve full native competence, corrective feedback is common in L2 and may indeed be necessary for most learners to ultimately reach native-like levels of proficiency when that is the desired goal.7.Explain ZPD. How would scaffolding put a student in ZPD?Zone of Proximal Development, this is an area of potential development, where the learner can achieve that potential only with assistance. Mental functions that are beyond an individual's current level must be performed in collaboration with other people before they are achieved independently. One way in which others help the learner in language development within the ZPD is through scaffolding. Scaffolding refers to verbal guidance which an expert provides to help a learner perform any specific task, or the verbal collaboration of peers to perform a task which would be too difficult for any one of them individually. It is not something that happens to learners as a passive recipient, but happens with a learner as an active participant.8.Think of a macrosocial factor that affects English learning in China. Which of does it fall under? What arethe effects? What are the results?The 5 topics are:●Global abd national status of L1 and L2●Boundaries and identities●Institutional forces and constraints●Social categories。
Friendship and cooperation are two essential elements in our lives that often go hand in hand.When it comes to the topic of cooperation among friends,there are numerous aspects to consider,from the benefits of working together to the challenges that may arise. Heres an essay that explores the theme of cooperation between friends.Title:The Essence of Cooperation Among FriendsIn the tapestry of life,friendship is a thread that weaves together the fabric of our existence,providing comfort,support,and a sense of belonging.Cooperation,on the other hand,is the loom that strengthens the bond between friends,creating a more intricate and resilient connection.The synergy between friendship and cooperation is a powerful force that can lead to personal growth,shared achievements,and a deeper understanding of one another.The Benefits of Cooperation Among Friends1.Enhanced ProblemSolving Skills:When friends collaborate,they bring together a diverse range of perspectives and ideas.This collective intelligence can lead to innovative solutions to problems that might be challenging to solve individually.2.Shared Learning Experiences:Working together on a project or task allows friends to learn from one another.Each person can contribute their unique skills and knowledge, enriching the learning experience for all involved.3.Increased Motivation:The support and encouragement from friends can be a significant motivator.Knowing that friends are working towards a common goal can inspire individuals to push beyond their limits and achieve more than they might have on their own.4.Strengthened Bonds:Cooperation can deepen the emotional connection between friends.The trust and reliance on one another that is necessary for successful collaboration can lead to a stronger,more enduring friendship.5.Personal Growth:Engaging in cooperative endeavors can help individuals develop important life skills such as communication,negotiation,and leadership.These skills are invaluable not only in personal relationships but also in professional settings.Challenges in Cooperative Friendships1.Conflict Resolution:Disagreements are inevitable when working closely with others.Friends must learn to navigate these conflicts with maturity and respect to maintain the health of their relationship.2.Division of Labor:Ensuring that each person contributes equally to a task can be challenging.It requires clear communication and a willingness to adjust roles as needed to ensure fairness.3.Time Management:Coordinating schedules and finding time to work together can be difficult,especially when friends have other commitments.Effective time management is crucial to the success of any cooperative endeavor.4.Maintaining Balance:While cooperation can strengthen friendships,it is important to maintain a balance between collaborative work and personal time.Overdependence on friends for all activities can strain the relationship.5.Handling Success and Failure:Sharing in the outcomes of a project,whether positive or negative,can be a test of friendship.Celebrating successes together and learning from failures can strengthen bonds,but it requires humility and a growth mindset. ConclusionCooperation among friends is a dynamic process that can lead to remarkable outcomes.It is a testament to the power of unity and the value of diverse contributions.While it presents challenges that require patience,understanding,and effective communication, the rewards of a cooperative friendship are profound.By embracing the spirit of collaboration,friends can achieve more together than they ever could alone,creating a legacy of shared experiences and mutual growth.。
Improving Interoperability in Collaborative ModellingS. Roser1 and B. Bauer11Programming of Distributed Systems, Institute of Computer Science, University of Augsburg, D-86135 Augsburg, Germany [roser|bauer]@informatik.uni-augsburg.deAbstract. The application of model-driven development facilitates faster and more flexible integration by separating system descriptions to different levels of abstraction. In crossorganisational development new challenges arise to enable enterprise models sharing knowledge independent of language and tools. However, interoperability problems in modelling can be hardly overcome by solutions operating essentially at syntactical level. This paper presents an approach using the capabilities of semantic technologies in modeldriven development and discusses its improvements for collaborative modelling.1 IntroductionIn its vision for 2010 [12] the IDEAS network stated, that for enabling enterprises to seamlessly interoperate with others it will be necessary to integrate and adapt ontologies in architectures and infrastructures to the layers of enterprise architecture and to operational models. Since it is necessary to have different methodologies, for different purpose and enterprise’s role, interoperability between enterprise models has to be achieved, where two different enterprise models can share the knowledge independent of language and tools. Therefore mappings between different existing enterprise modelling formalisms based on an enterprise modelling ontology as well as tools and services for translating models have to be developed (IDEAS analysis - gap 12 [11]). Still, solutions aiming to improve such kind of interoperability (like [3], [15], [21]) address the problems of different representation formats, modelling guidelines, modelling styles, modelling languages, and methodologies at syntactical level, focusing on metamodels’ abstract and concrete syntax. Approaches providing interoperability solutions based on ontologies and automated reasoning are lacking of key features for modelling [7], like storing trace information of transformation executions in order to enable transactions or incremental updates when executing transformations [17]. To support the business2S. Roser and B. Bauerinteroperability needs of an enterprise, in [5] a rather abstract interoperability framework for model-driven development of software systems is proposed. Mutual understanding on all levels of integration, conceptual, technical, and applicative, has to be achieved. The conceptual reference model is used to model interoperability, where metamodels and ontologies will be used to define model transformations and model mappings between the different views of an enterprise system. In this work we present how the concrete approach of ontology-based model transformations (ontMT) ([18]) can be applied for improving interoperability between enterprise models despite of different modelling languages and tools. OntMT integrates ontologies in modelling by utilising different technological spaces [14] (namely MDA and Ontology technological space) automating generation of model transformations and mappings between metamodels. Interoperability in modelling is fostered by employing automated reasoning technology from ontology engineering technological space to the generation of model transformations. The paper is organized as follows: After introducing background information to our work in section 2, section 3 discusses challenges of collaborative modelling in a motivational scenario before in section 4 core problems are identified. The approach of ontology-based model transformation is presented in section 5 and 6. Section 7 discusses how the ontMT approach contributes to the interoperability scenarios described in section 3. Finally we discuss related work (section 8) and conclude with a short summary.2 BackgroundModel-driven Development: Model-driven development (MDD), as a generalization of OMG™’s Model-driven Architecture paradigm (MDA®), is an approach to software development based on modelling and automated transformation of models to implementations. In MDD models are more than abstract descriptions of systems, as they are used for model- and code refinement – they are the key part of the definition of a software system. Largely automated model transformations refine abstract models to more concrete models (vertical model transformations) or simply describe mappings between models of the same level of abstraction (horizontal model transformations). Beneath of commercial products facilitating MDA there exist open source projects dedicated to MDD. The Eclipse Generative Modeling Tools project (GMT) [8] provides a set of research tools illustrating operations applicable to abstract models. Those tools range from code generation (oAW, MOFScript) over model transformation and weaving (ATL, AMW) to model management (AM3). The MODELWARE project aims to close the gap between the end-users and solutions of currently used software development methods by using models for the construction of software. It contributes to the Eclipse Model Driven Development integration project (MDDi). MDDi is dedicated to offer a platform the integration facilities needed for applying a MDD approach. It aims to provide the ability to integrate modelling tools to create a customizable MDD environment.Improving Interoperability in Collaborative Modelling3Models: The definition of the mega-model (a model about modelling) presented in [6] describes a model as a system that enables us to give answers about a system under study without the need to consider directly this system under study (SUS). In short a model is representationOf a system, where systems can be physically observable elements like models or, more abstract concepts like modelling languages. A modelling language is a set models. Models are elementsOf a modelling language, if they conformTo a model of the modelling language (i.e. a metamodel). For one modelling language multiple (meta)models can exist, which can again differ in the language they are described in.MetaModel MetaModel MetaModelrepOfSystem / Modelling LanguageelementOf/conformToModelModelModelrepOfSystem / SUSFig. 1. Modelling languages, metamodels, models and their relationshipsModel transformations: Model transformations (MTs) are specified between metamodels. By executing a model transformation models conforming to the source metamodels are transformed to models conformant to the target metamodel. Vertical model transformations refine abstract models to more concrete models while horizontal model transformations describe mappings between models of the same level of abstraction. As model transformations play a key role in MDD, it is important that transformations can be developed as efficiently as possible [7]. With the MOF 2.0 Query, Views, and Transformation (QVT) specification [17] the OMG provided a standard syntax and execution semantics for transformations used in a MDD tools chain. QVT model transformations are specified themselves as models. Beneath vertical and horizontal model transformations, one has to distinguish whether the source and target models are element of the same language and conform to the same metamodel. An in-place transformation (same source and target model) can be used refactoring models. Ontology: Ontologies are considered a key element for semantic interoperability and act as shared vocabularies for describing the relevant notions of a certain application area, whose semantics is specified in a (reasonably) unambiguous and machine-processable form [4]. According to [16] an ontology differs from existing methods and technologies in the following way: (i) the primary goal of ontologies is to enable agreement on the meaning of specific vocabulary terms and, thus, to facilitate information integration across individual languages; (ii) ontologies are formalized in logic-based representation languages. Their semantic are thus specified in an unambiguous way. (iii) The representation languages come with executable calculi enabling querying and reasoning at run time. Application ontologies contain the definitions specific to a particular application [10], while reference ontologies refer to ontological theories whose focus is to clarify the intended meaning of terms used in specific domains.4S. Roser and B. BauerTechnological Spaces: Kurtev et al. [14] introduce the concept of technological spaces (TS) aiming to improve efficiency of work by using the best possibilities of different technologies. A technological space is in short a zone of established expertise and ongoing research. It is a working context with a set of associated concepts, body of knowledge, tools, required skills, and possibilities. Initially five technological spaces (MDA TS, XML TS, Abstract Syntax TS, Ontology TS, DBMS TS) have been presented in [14], of which the MDA TS and the Ontology TS are important for our work. In the MDA TS models are considered as first-class citizens, representing particular views on the system being built. The Ontology TS can be considered as a subfield of knowledge engineering, mainly dealing with representation and reasoning.3 Motivational ScenarioInteroperability can broadly be characterized as ‘the ability of enterprises to cooperate seamlessly with each other’. Interoperability is not only an issue of information and communication systems (ICT-systems) collaborating at runtime. It is also a matter of communicating both with internal and external organisation units in order to develop new models for collaboration and supporting ICTSystems. Information and knowledge about enterprises, their organisational structure, processes, collaboration with external organisation but also ICT-systems is commonly captured in models. To enable collaboration in enterprise and systems modelling, enterprises have to be supported by interoperability solutions for model sharing and model exchange independent of modelling languages and tools.Enterpr.

Scenario realizing cross-organisational business process modelling and executionImproving Interoperability in Collaborative Modelling5Figure 2 illustrates the application of MDD to cross-organisational business process development. The vertical dimension distinguishes the different layers of abstraction applied in MDD and the horizontal dimension represents the collaborative modelling between two enterprises A and B. Models of enterprise A and B have to be shared at different level of abstraction in order to agree on and develop cross-organisational business processes. A concrete scenario implementing cross-organisational business process modelling and execution like show in figure 2 has been developed in the ATHENA project (more details can be found in [9]). Enterprise A and B develop models for their process (privates processes (PPs), view processes (VPs) and crossorganisational business processes (CBPs)) at three levels of abstraction, i.e. business expert, IT expert, and IT-system level. Vertical transformations, like presented in [1], encode knowledge about architecture and platform in order to transform models from higher level to models of lower abstraction level. For example ARIS models (eEPCs [13]) are transformed to models conformant to PIM4SOA [2]. Enterprise A and B use different modelling tools and languages at the various abstraction levels. At business level enterprise A uses ARIS while enterprise B applies Integrated Enterprise Modelling and the MO2GO tool [20]. To develop cross-organisational business process both enterprises have to provide public parts of their models as basis for discussion for collaborative modelling. The same holds for other levels of abstraction where the enterprises have to agree on more detailed issues of the cross-organisational business processes. Unfortunately there are issues preventing a more smooth realisation of such an MDD scenario. Two prominent candidates are a) the further advancements in modelling applied by the enterprises (like e.g. the application of new modelling languages or styles) and b) the exchange of models between the enterprises. Thus we have to deal with maintenance of model transformations and sharing models across inter-organisational relationships. Over a period of time enterprises will apply new (versions) of modelling languages and modelling styles. Therefore existing transformations have to be adjusted or developed. This can be a time consuming and error-prone task, since the vertical transformations of the different enterprises have to be aligned. The result of a refinement step (vertical transformation) not only depends on the next refinement step, but also on the other enterprises’ models at the same level of abstraction. Secondly, mappings have to be developed between the enterprises’ modelling languages and tools in order to get shared understanding of cross-organisational business process and to enable collaborative model-driven developing.4 Problem StatementDespite the differences in modelling at these levels of abstraction (like granularity of the models or differences in modelling approaches) the core principles (.e. representing information about real world things in models, see background section 2) and problems remain the same. The core barriers to model exchange and maintenance of model transformations are multiple representation formats and different modelling styles, serving the purposes of the particular application.6S. Roser and B. BauerDifferent representation format: The trend towards more and more people using domain specific languages (DSLs) to create their own domain specific models (DSMs) naturally results in a variety of different languages and metamodels. To exchange models conformant to these various metamodels (abstract syntax) model transformations have to be developed. Often there are even multiple model transformations for the same modelling language. Also time and again new versions of metamodels, e.g. the metamodels for UML 1.x and UML 2.x, are released. New model transformations have to be developed and existing model transformations have to be adjusted, whenever new versions replace the old ones. Though visual representations (concrete syntax) should be decoupled from internal representation (abstract syntax), in many cases different concrete syntax is considered in model transformations providing e.g. views on models. • Different semantics: Since the semantics of modelling languages’ concepts is rarely formally specified (in the UML specification this is plain English), different people and organisations can associate different semantics with the same concepts used in the metamodel. By applying special model styles and representation guidelines this is often done consciously, especially within the boundaries of one enterprise. Again, model transformations have to be specified enabling sensible exchange of models according to the respective interpretation of the involved partners. Enabling seamless inter-organisational collaboration and system development despite of this heterogeneity in modelling, automation is needed to share models amongst various organizations, maintain existing model transformations as well as to adjust existing model transformations.•5 The Approach of Ontology-based Model TransformationTo overcome those problems, ontMT facilitates methods to generate model transformations despite of structural and semantic differences of metamodels by applying semantic technologies of Ontology TS. Different versions of metamodels are bound to a reference ontology of a certain domain (see figure 3). Bindings (sem. Annotation) specify the semantic mapping from metamodels to the semantics of their concepts, i.e. to the reference ontology. To generate model transformations for various modelling languages ontMT makes use of reasoning mechanisms. The metamodels and the reference ontology are given, while the bindings of the metamodels to the reference ontology have to be specified. Finally an initial model transformation is needed, which is either given or generated automatically. The initial model transformation is a model transformation (e.g. from metamodel v1.5 to metamodel v2.0) in which transformation rules (and especially the semantics of the model transformations) are encoded and can be generated automatically in a bootstrapping process in the case of mappings. If e.g. a new model transformation from metamodel v1.5 to metamodel v2.1 has to be generated; only the delta between metamodel v2.0 and v2.1 has to be considered. The new model transformation is generated by substituting the concepts of metamodel v2.0 with the concepts of metamodel v2.1 in the initial model transformation.Improving Interoperability in Collaborative Modelling7Reference OntologyBinding(sem.

Ontology-based model transformation – overall approachThe ontology-based model transformation component consists of three main components: A model manipulator, an inference component and a Sem-MTComponent. The model manipulator and the inference component operate essentially in a single technological space, i.e. in the MDA and the Ontology TS respectively. The Sem-MT-Component establishes the link between the two TS, by using the reasoning results to trigger the modification of the model transformation’s model (for a more detailed description and examples see [18]). The reasoner of the inference component is triggered by a set of rules specific to the model transformation approach. The reasoning computes information about all relationships important for ontMT (the main relationships between ontology elements identified in [19]: equivalence, containment, and overlap) and adds them to a knowledge base. The knowledge base can be queried for these relationships. The model manipulator provides modification operations on model transformations (the model transformations are models) and the respective metamodels. It solely works on the abstract syntax of the (meta)models in the MDA TS. It also checks, whether the modifications proposed by the inference component can sensibly be applied, i.e. if the proposed substitution produces type conformance errors or connections between transformation rules are lost. The Sem-MT-Component implements the core part of the ontMT approach. It realizes the main functionality of ontology-based model transformation by using inference results of the Ontology TS to gain a queue of adjustment operators for the modification and generation of model transformations in the MDA TS. After the model manipulator has identified metamodel’s concepts, which have to be substituted in the model transformation, the Sem-MT-Component queries the inference component and computes the ‘best possible’ substitution of the metamodel’s concepts (as a queue of adjustment operators) using heuristics.6 Automating Model Transformation DevelopmentModel transformations between various modelling languages can be automatically derived and generated by the ontMT approach (see figure 3). In this section we8S. Roser and B. Bauerdescribe the procedure to generate mappings (i.e. semantically identical model transformations) between a modelling language A and a modelling language B. For both languages exists abstract syntax NA/NB in various technological spaces: A has (like B) an abstract syntax in the MDA TS NA-mda and the Ontology TS NA-ont which are synchronized. Thus we can work with the syntax and the capability of that technological space better suited for solving a problem (see figure 4a). Semantics of the concepts is described by the means of the semantic domain SD and its notation (e.g. OWL) in a reference ontology NRO. Semantics of languages is defined by semantic mappings to the semantic domain MA: A → SD and MB: B → SD. The ontological grounding1 is a notation of the semantic mapping from NA-ont to NRO. The goal of the transformation to generate is to define ‘identity’ relationships between the concepts of A and B. The model transformation MTmapAB: A ↔ B between A and B has the following semantics MMTmapAB: MTmapAB → id, where id is the identical mapping.1MTAA: A ↔ A NMTAA2 σ(MTAA )=MTABNANA'AMA: A → SDNM AOntology TSSDrepresenationOfNA-mdaNA-ontNRONANMTAB MTAB: A ↔ BNBa)MDA TSb)3Fig. 4. a) Modelling language, semantic mapping, semantic domain and their representations; b) Procedure of automated mapping generationThe generation procedure works on the model of the model transformation and the models of the modelling languages, and exploits the ontological grounding to the reference ontology. On the basis of reasoning results gained in the Ontology TS, modification operations are called to obtain the new model transformation working solely on the model of the model transformation and the metamodels. To generate the model transformation MTmapAB the following steps are performed (see figure 4b): • An initial model transformation MTmapAA: A ↔ A is automatically generated, mapping A on itself. This bootstrapping step is necessary to obtain a first model of the model transformation (transforming NA to NA') 2, which only has to be adjusted by modifications operators. Assuming the same ontological grounding for NA and NA', the bootstrap model transformation is an id: MMTmapAA: MTmapAA → id. • The inference engine derives interrelationships in between NA' and NB in the Ontology TS. This is possible, since both NA' and NB are mapped to the1The definition of the ontological grounding is a semantic annotation comprising static semantics of the metamodels, i.e. the semantics of the concepts, i.e. an ontology. 2 A simple version of such a mapping can easily be generated on basis of a metamodel in the MDA TS. By traversing the metamodel via its containment relationships the appropriate mapping rules can be generated.Improving Interoperability in Collaborative Modelling9same reference ontology NRO. It is computed, how the concepts of NA' can be substituted by semantically identical concepts of NB (σ(MTmapAA)=MTmapAB). Those interrelationships can be transferred to the MDA TS as the modelling languages A and B have synchronous representations in both MDA TS and Ontology TS. • Finally the concepts of NA' are substituted with the concepts of NB in the model of MTmapAA and we obtain a model of the model transformation MTmapAB with MMTmapAB: MTmapAB→ id. The substitution is performed via modification operations on the abstract syntax (model) of the model transformation MTmapAA in MDA TS. The first (bootstrapping) step helps to extend our approach to scenarios in which given model transformations have to be adjusted to modelling languages and metamodels for which they initially have not been designed. The bootstrap transformation is simply replaced by a given (already existing) transformation and step 2 and 3 can be performed like described above. Avoiding to derive model transformations directly from ontologies results in a more flexible and wellstructured architecture. OntMT can both generate new model transformations and easily reuse knowledge encoded in existing transformations. Issues concerning the model transformation, like checking if its model conforms to the QVT metamodel or considering the cardinality of associations’ ends, are all dealt within the MDA TS. The Sem-MT-Component invokes modifications operations on the basis of the reasoning results and the application of heuristics. More detailed technical description of the approach can be found in [18].7 Application of our Contributions to Interoperability ScenariosIn this section we discuss how the ontology-based model transformation approach contributes in solving the challenges of collaborative modelling presented in section 3. The overview in figure 5 depicts two different types of model transformations in the horizontal domain, mapping and refinement, and the challenges for applying model transformations for collaborative modelling in the vertical domain. Mappings are model transformations on a certain level of abstraction where no information is lost and no additional information is added to the models. Refinements are model transformations adding additional information about e.g. architecture or platform to the generated model. Thus the target model of a refinement is more detailed than the source model. Previously in the motivation we have identified two main challenges for realising smooth cross-organisational MDD: model sharing and model transformation maintenance. In model sharing scenarios collaborating organisations exchange information either directly or via a shared modelling space by the means of their models and model transformations. New organisations join the information exchange, though often there exists no transformations for their information representation (i.e. their models). In maintenance scenarios model transformations for transforming certain models already exist. Due to the continuous evolution of modelling languages, metamodels and modelling styles used for modelling by the organisations existing model transformation have to be adjusted.10S. Roser and B. BauerThe values of the table in figure 5 represent how the ontology-based model transformation approach supports interoperability in collaborative modelling for the various scenarios. For example for model sharing between different metamodels ontMT can most likely generate model transformations automatically for exchanging those models. The automated generation also includes automated generation of the necessary bootstrap model transformation. In the case of automated modification (autom.mod.) existing model transformations are e.g. adjusted to new source or target metamodels. If there exists no initial model transformation and it cannot be generated automatically, the initial model transformation has to be specified manually (man.).Mapping Model Sharingautom.gen.

Application of ontMT to model sharing and model transformation maintenanceOntMT supports the collaborative modelling challenges and model transformation types in different ways regarding the problems of different DSLs, metamodels and modelling styles described in section 4. In the case of dealing with different and new metamodels and modelling styles ontMT is able to automatically generate mappings for model sharing. OntMT supports maintenance of existing mappings in two different ways, either generating new mappings or modifying existing ones. The more individual features, which are different to the core structure of the metamodels, are encoded in existing mappings, the more preferable it is to modify this mappings. Generating new mappings will be preferred, if the new metamodel provides extensions to the old ones or new modelling styles specify fundamental different composition of modelling elements. For maintaining refinements ontMT provides the possibility of automated modification and adjustment. These model transformations cannot be totally automatically generated, since individual knowledge about software architecture or platform is encoded, e.g. the application of patterns like broker, model-view-controller, etc.. Model transformations between different DSLs are supported by ontMT in a similar way. Whether it is possible to generate the mapping totally automatically depends on how different the DSLs and their modelling approaches are. In ontMT knowledge about the concepts of DSLs is captured in bindings to the reference ontology. So, if two DSLs totally differ in e.g. their modelling approaches their bindings will be to mostly unconnected subsets of the reference ontology. In order to generate model transformations with ontMT additional transformation knowledge could be encoded in the bindings. However, in our opinion, the better solution is to encode this transformation knowledge in an initial model transformation. If the DSLs can be sensibly connected to similar sets of the RO, we obtain reasoning result which can be used for fully automated model transformation generation and adjustment.。
