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、The main purpose of the Teaching Syllabus for Senior High School English is to_______.A. test students’ English proficiencyB. guide the curriculum and teaching processC. evaluate teachers’ teaching performanceD. assess students’ knowledge in literatureAnswer: B. guide the curriculum and teaching process解析: The Teaching Syllabus for Senior High School English serves as a guideline for educators on how to plan and implement their English courses, ensuring that the learning objectives are met and that the curriculum covers a comprehensive range of skills and knowledge necessary for students to succeed in English.2、What is the primary focus of the “Reading and Writing” s ection in the English curriculum for senior high school students?A. Developing listening skillsB. Building a rich vocabularyC. Improving reading and writing skillsD. Enhancing speaking skillsAnswer: C. Improving reading and writing skills解析: The “Reading and Writing” section of the English curriculum for senior high school students primarily focuses on developing students’ abilities to read various texts critically and to compose their own coherent and structured writing pieces.3、Which of the following vocabulary words is most suitable for use in a high school English lesson focusing on cultural comparison?A)ContemporaryB)ManifestC)ConspicuousD)AcquiesceAnswer: C) ConspicuousExplanation: C) Conspicuous fits best in the context of a high school English lesson that focuses on cultural comparison because it describes something that is easily noticed or observed, which can be relevant when discussing cultural differences and similarities. contemporary, manifest, and acquiesce are all good words but are not as closely related to the theme of cultural comparison.4、In a lesson on “Great Expectations” by Charles Dickens, which of the following literary devices would be most appropriate to analyze the character development of Pip?A)MetaphorB)ForeshadowingC)IronyD)AnecdotesAnswer: B) ForeshadowingExplanation: B) Foreshadowing would be the most appropriate literary device to analyze the character development of Pip in “Great Expectations.” Foreshadowing involves anticipating future actions or events through hints or clues and is often used to build suspense and depth in fiction. By analyzing foreshadowing, students can better understand how Pip’s character evolves throughout the novel. While metaphor, irony, and anecdotes are all pertinent literary devices, foreshadowing is specifically fruitful for character development analysis.5、The sentence “She has a knack for remembering faces.” is an example of which figure of speech?A)MetaphorB)SimileC)HyperboleD)OxymoronAnswer: D) OxymoronExplanation: An oxymoron is a figure of speech that combines contradictory terms. In this sentence, “a knack” suggests a natural talent, which is usually seen as a positive trait, but when combined with “for remembering faces,” it implies an unusual ability to remember faces, creating a contradiction.6、In the following sentence, which word is the main verb?“The students are eager to learn new vocabulary.”A)EagerB)LearnC)NewD)VocabularyAnswer: B) LearnExplanation: The main verb in a sentence is the action word that carries the primary meaning. In this sentence, “learn” is the action being performed by the students, making it the main verb. “Eager” is an adjective describing the state of the students, “new” is an adjective modifying “vocabulary,” and “vocabulary” is the object of the verb “learn.”7、What is the main purpose of using a dictionary in the English language learning process?A. To improve pronunciationB. To enhance vocabularyC. To develop listening skillsD. To practice writingAnswer: B. To enhance vocabularyExplanation: The primary purpose of using a dictionary in the English language learning process is to enhance vocabulary by looking up the meanings, spellings, and usage of unfamiliar words. While dictionaries can also help with pronunciation and provide information about grammar and usage, their mainfunction is to aid in vocabulary expansion.8、In a high school English classroom, which of the following strategies is most appropriate for encouraging critical thinking among students?A. Providing answers to students’ questionsB. Leading students through a structured discussionC. Assigning extensive reading assignmentsD. Conducting repetitive grammar exercisesAnswer: B. Leading students through a structured discussionExplanation: Leading students through a structured discussion is an effective strategy for encouraging critical thinking as it allows students to engage in meaningful dialogue, analyze different perspectives, and formulate their own opinions. This approach fosters critical thinking skills, whereas the other options focus more on providing information or repetition without promoting active thinking.9、Which of the following best describes the main difference between dictionary definition and the usage examples provided?A、A dictionary definition provides the historical usage of a word, while usage examples show current usage.B、A dictionary definition gives the formal meaning of a word, while usage examples illustrate informal or context-specific usage.C、A dictionary definition is always correct, while usage examples may be outdated.D、A dictionary definition is for advanced learners, while usage examples are for beginners.Correct Answer: BExplanation: A dictionary definition typically provides the formal or base meaning of a word, which can be interpreted in a variety of contexts. Usage examples, on the other hand, illustrate how the word is used in different contexts or demonstrate its informal or specific meanings. Therefore, optionB accurately describes the main difference between the two.10、In teaching the subjunctive mood in English, which of the following is the best example to demonstrate the usage of ‘should + be’?A、It is suggested that the meeting should be rescheduled for next week.B、The council insists that everyone should be allowed to speak.C、The advice given is that the students should be more organized.D、The teacher recommends that the assignment should be handed in on time.Correct Answer: AExplanation: The subjunctive mood is often used to express a desire, a suggestion, or a recommendation in a formal or polite way. The correct usage of the subjunctive mood with “should + be” is typically in clauses introduced by words such as “suggested,” “demanded,” “insisted,” “recommended,” and “proposed.” In this context, option A is the best example because it uses “should be rescheduled” in a suggestion for a future action.11、In the following sentences, which one correctly uses the gerund as asubject?A. Waiting for the bus is sometimes boring.B. To wait for the bus is exciting.C. Waiting for the bus, I met an old friend.D. Waiting for the bus, I feel restless.Answer: AExplanation: The correct use of the gerund as a subject occurs in option A. “Waiting for the bus” is the gerund phrase serv ing as the subject of the sentence, while in options B, C, and D, the gerund is used incorrectly in different structures.12、Which of the following sentence structures is used to convey a purpose or reason for an action?A. Because he likes math, he studied all night.B. He studied all night; he dislikes math.C. He studied all night, because he wanted to pass the exam.D. To study all night, he used a book.Answer: CExplanation: The sentence structure that conveys a purpose or reason for an action is option C. The phrase “because he wanted to pass the exam” directly expresses the reason why he studied all night. Options A, B, and D do not correctly convey a purpose or reason for the action.13、The teacher’s role in the classroom is best described as:A) A facilitator of student learningB) A disseminator of informationC) A controller of student behaviorD) A subject matter expertAnswer: A) A facilitator of student learningExplanation: The role of a teacher in the classroom is increasingly viewed as that of a facilitator of learning, focusing on creating a supportive environment where students can explore and develop their understanding of the subject matter. This approach emphasizes student-centered learning rather thana one-way transmission of information.14、Which of the following is NOT an essential component of lesson planning for a high school English class?A)Objectives and goalsB)Assessment methodsC)Student engagement activitiesD)Teaching methodsAnswer: B) Assessment methodsExplanation: While assessment methods are an important part of the overall teaching and learning process, they are typically not the central focus of lesson planning. Lesson planning primarily involves outlining the objectives and goals, planning the activities (including student engagement), and selecting the appropriate teaching methods to achieve these goals. Assessment methods are often addressed separately in the broader context of curriculum design or unitplanning.15、Which of the following is NOT a characteristic of communicative language teaching (CLT)?A. Focus on fluencyB. Emphasis on grammar accuracyC. Use of authentic materialsD. Interaction and communicationAnswer: B. Emphasis on grammar accuracyExplanation: Communicative Language Teaching (CLT) emphasizes the use of language for communication and interaction. It focuses more on fluency than on grammatical accuracy, though accuracy is still important. Authentic materials are often used to provide real-life contexts for learning. Therefore, the emphasis on grammar accuracy does not align with the primary goals of CLT.16、In a high school English class, which activity would best promote higher-order thinking sk ills according to Bloom’s Taxonomy?A. Memorizing vocabulary listsB. Writing an essay comparing two literary textsC. Completing a fill-in-the-blank worksheetD. Listening to a dialogue and answering comprehension questionsAnswer: B. Writing an essay comparing two literary textsExplanation: According to Bloom’s Taxonomy, higher-order thinking skills include analyzing, evaluating, and creating. Writing an essay that requiresstudents to compare and contrast two literary texts involves these higher-order thinking skills because it necessitates analysis of the texts, synthesis of information, and the creation of a coherent argument. The other activities listed primarily involve lower-order thinking skills such as remembering and understanding.17、The following sentence is a question. Which of the following is the correct intonation pattern for it?A. /ˈwɔːt/ /ˈwɜːt/ /ˈwɔːt/B. /ˈwɔːt/ /ˈwɜːt/ /ˈwɔːt/C. /ˈwɔːt/ /ˈwɜːt/ /ˈwɔːt/D. /ˈwɔːt/ /ˈwɜːt/ /ˈwɔːt/Answer: AExplanation: The intonation pattern for a yes/no question is rising in the final syllable, which is why the correct pattern for the word “what” in a question is /ˈwɔːt/ /ˈwɜːt/ /ˈwɔːt/. The rising tone indicates that it is a question.18、Choose the appropriate verb form to complete the following sentence. The students_______(to study) hard for the upcoming exam.A. are studyingB. have studiedC. have been studyingD. will studyAnswer: AExplanation: The sentence is in the present continuous tense to describe an action t hat is currently happening. Therefore, “are studying” is the correct form to complete the sentence. The other options are incorrect because they suggest past or future actions.19、In the following options, which one is the most significant characteristic of the American educational system?A. Uniform curriculum for all studentsB. Emphasis on standardized testingC. Strong emphasis on teacher autonomyD. High teacher-to-student ratiosAnswer: C. Strong emphasis on teacher autonomy解析:The American education system places a strong emphasis on teacher autonomy, meaning teachers have considerable freedom in their instructional approaches and decision-making. In contrast, with options (A) and (B), they often provide more centralized control over curriculum and tests. Option (D) is generally not accurate for many public schools, as class sizes can vary widely.20、Which of the following strategies is most effective for teaching advanced English language learners in a high school setting?A. Using exclusively simplified EnglishB. Incorporating authentic texts and multimedia resourcesC. Avoiding complex grammatical explanationsD. Focusing solely on vocabulary buildingAnswer: B. Incorporating authentic texts and multimedia resources解析:Incorporating authentic texts and multimedia resources is a highly effective strategy for advanced English language learners as it helps them understand real-world English usage and enhances their cultural awareness. It also provides them with a variety of contexts to practice their language skills. Using exclusively simplified English (A) may not help in developing their proficiency, avoiding complex grammatical explanations (C) could prevent them from mastering more advanced language structures, and focusing solely on vocabulary building (D) might not adequately develop their communicative skills.21.What is NOT a characteristic of a well-structured lesson plan for a high school English class?A)Clear learning objectivesB)Detailed description of the teaching strategiesC)Inadequate time allocation for activitiesD)Accurate grammar and vocabulary focusAnswer: CExplanation: An effective lesson plan for a high school English class should include clear learning objectives, detailed description of teaching strategies, and accurate grammar and vocabulary focus. Adequate time allocation is also important; however, an inadequate time allocation can also be a characteristic of a poorly planned lesson. The question specifically asks for what is NOT acharacteristic, making “Inadequate time allocation for activities” the correct answer.22.Which of the following statements about using multimedia in high school English classrooms is FALSE?A)Multimedia can increase engagement and motivation.B)It can provide a diverse range of learning opportunities.C)It can lead to a decrease in teacher’s role as the sole provider of content.D)Incorporating multimedia in teaching is always the most effective method.Answer: DExplanation: The use of multimedia in the classroom can indeed increase engagement, provide diverse learning opportunities, and may lead to a decrease in the teacher’s role as the sole provider of content. However, the false statement is that incorporating multimedia in teaching is always the most effective method. The effectiveness of multimedia resources can vary based on context, student needs, and the subjects being taught. Therefore, “Incorporating multimedia in teaching is always the most effective method” is not a universally true statement.23.The following sentence is an example of which tense?A. Simple PastB. Present PerfectC. Past PerfectD. Present ContinuousAnswer: D. Present ContinuousExplanation: The sentence “The students are playing soccer in the school field right now.” u ses the present continuous tense to describe an action that is happening at the moment of speaking.24.Which of the following words is the correct past participle form of the verb “begin”?A. BegunB. BeggingC. BegD. BeggedAnswer: A. BegunExplanation: The past participle form of the verb “begin” is “begun.” It is used in perfect tenses and passive voice. For example, “The task has been begun by the students.”25、Which of the following words has a different pronunciation for the underlined part?A. bookB. cookC. lookD. foodAnswer: D. foodExplanation: In options A, B, and C, the underlined letters (b, c, l) are all pronounced as /k/ when they are followed by ‘oo’ in British English,resulting in the sound /ʊk/. However, in option D, the word ‘food’ ha s a different pronunciation for the ‘oo’ combination, which sounds like /uːd/. Therefore, D is the correct choice as it does not follow the same phonetic rule as the other three options.26、Choose the sentence that correctly uses the passive voice.A. The book was read by John.B. The book read by John.C. The book reads by John.D. The book reading by John.Answer: A. The book was read by John.Explanation:The passive voice is formed with the auxiliary verb “be” plus the past participle of the main verb. In this case, the correct form is “was read,” which indicates that the action (reading) was done to the subject (the book) by the agent (John). Options B, C, and D do not use the correct structure for the passive voice, making A the only correct answer.27.The following sentence contains a misplaced modifier. Which sentence correctly fixes the error?A. Walking across the street, she accidentally stepped on a nail.B. Accidentally stepping on a nail, she was in a lot of pain.C. She accidentally stepped on a nail, which was on the street.D. She stepped on a nail, accidentally, and it hurt her foot.Answer: CExplanation: The correct placement of the misplaced modifier “accidentally” is after “stepped on a nail” to clarify that the action of stepping on the nail was accidental. Option C correctly fixes the error by placing the modifier in the correct position.28.Which of the following sentences is a fragment?A. Walking down the hallway, the bell rang.B. He was late because he had to take an extra class.C. She spoke with enthusiasm, her voice filled with excitement.D. The book, written by Jane Austen, is a classic.Answer: AExplanation: A fragment is a group of words that could be a complete sentence but lacks a main verb or is incomplete. Option A is a fragment because it is a participial phrase (“Walking down the hallway”) that acts as a dependent clause and cannot stand alone as a complete sentence. The rest of the options contain complete sentences with a main verb and convey a complete thought.29、The verb “inherit” means “to receive or acquire something that was owned by someone who has died” from your __(A) options are:A) ancestorB) ancestor’sC) ancestors’D) ancestorsAnswer: B) ancestor’sExplanation: The possessive form after a verb is often used with “oneself、” or “ones” to show that it refers back to the subject. In this case, “inherit” refers to receiving something from one’s ancestor. Therefore, “ancestor’s”is the correct choice to indicate possession.30、In the sentence “The teacher asked the students to analyze the theme of the novel,” the word “asked” is the past tense of “__” verb.A) askB) askingC) hearD) heardAnswer: A) askExplanation: The given sentence indicates a completed past action, which means the action of asking has already been done. “Ask” is the base form of the verb, while “asked” is the past tense form of “ask.” “Hear” does not properly continue the tense consis tency of the sentence, and “heard” would be the past particle form, not used in this context.二、简答题(20分)II.Short Answer QuestionsQuestion:Discuss the importance of integrating cultural elements into high school English language teaching. Provide at least three reasons why this approach is beneficial and explain how itcan be implemented in the classroom.Answer:Integrating cultural elements into high school English language teaching is crucial for several reasons:1.Enhances Understanding and Appreciation of Diversity: By incorporating materials that reflect the cultures of English-speaking countries as well as other global cultures, students can develop a deeper understanding and appreciation of diversity. This not only enriches their language learning experience but also prepares them to be more culturally sensitive and globally aware citizens.2.Improves Language Proficiency: Exposure to authentic texts and media from different cultures can provide learners with a richer context for language use. It helps students understand idiomatic expressions, colloquialisms, and cultural references that are often key to achieving higher levels of language proficiency. This exposure can make language learning more engaging and meaningful.3.Promotes Critical Thinking and Creativity: Cultural content can serve asa catalyst for critical thinking and creativity. When students analyze cultural practices or compare and contrast their own culture with others, they are encouraged to think beyond surface-level differences and consider the underlying values and beliefs. This process can enhance cognitive skills and foster a more open-minded and empathetic worldview.Implementation Strategies:•Use Authentic Materials: Incorporate authentic reading and listeningmaterials such as literature, films, music, and news articles thatrepresent various cultures. These materials should be age-appropriate and relevant to the students’ interests and backgrounds.•Cultural Activities and Projects: Design activities and projects that require students to explore and present on different aspects of culture.For example, students could create posters about festivals fromEnglish-speaking countries, conduct interviews with native speakers, or organize a multicultural day in the classroom.•Guest Speakers and Field Trips: Invite guest speakers who can share firsthand experiences of different cultures or arrange field trips to cultural institutions like museums, art galleries, or cultural festivals where students can engage directly with cultural artifacts and practices.By integrating cultural elements into the curriculum, teachers can create a dynamic and inclusive learning environment that not only promotes language acquisition but also fosters personal growth and social development.This question and answer format aligns with the standards expected in teacher qualification exams, aiming to assess candidates’ ability to apply theoretical knowledge to practical teaching scenarios.三、教学情境分析题(30分)Question: Teaching Scenario AnalysisScenario:Mr. Smith is a high school English teacher who is preparing a lesson on the theme of “Global Warming” for his eleventh-grade class. The class consists of 30 students with varying levels of English proficiency. Mr. Smith has a total of 45 minutes for the lesson. He has gathered the following materials:1.A powerpoint presentation on “Global Warming”2.A handout with relevant vocabulary words and their definitions3.A short video clip showing the effects of global warming4.A set of discussion questions5.A worksheet with comprehension questionsTask:Based on the given scenario, analyze Mr. Smith’s teaching approach and suggest improvements to enhance student engagement and learning outcomes.Answer:Teaching Approach Analysis:Mr. Smith’s teaching approach for the lesson on “Global Warming” shows a blend of traditional and interactive methods. He begins with a powerpoint presentation to introduce the topic and provide a structured overview. This approach helps to set the context and deliver key information. Additionally, the handout with vocabulary words and their definitions ensures that students are familiar with the necessary terms to understand the content.The inclusion of a video clip is a good strategy to engage students visually and provide real-life examples of global warming. This approach helps toreinforce the lesson and make it more relatable. Furthermore, the discussion questions encourage students to think critically and share their opinions, which promotes active learning.However, there are areas where Mr. Smith can improve his teaching approach:1.Interactive Activities: Instead of just presenting the information, Mr.Smith can incorporate more interactive activities. For instance, he can divide the class into small groups and assign each group a specific aspect of global warming to research. They can then present their findings to the class, fostering collaboration and active learning.2.Differentiated Instruction: Recognizing the varied proficiency levels among students, Mr. Smith should consider using varied teaching methods to cater to different learning styles. For example, he can provide visual aids or additional explanations for students who may struggle with the vocabulary and concepts.3.Assessment: Mr. Smith can incorporate formative assessments, such as quizzes or exit tickets, to gauge students’ understanding of the lesson and identify areas that require further clarification.Suggestions for Improvement:1.Interactive Group Activity: Assign students to research different aspects of global warming (e.g., causes, effects, and solutions) and present their findings to the class. This will encourage collaboration, critical thinking, and deeper understanding of the topic.2.Differentiated Instruction: Provide additional support for students with lower proficiency levels by offering visual aids, breaking down complex vocabulary, and offering simplified explanations.3.Formative Assessment: Implement short quizzes or exit tickets at the end of the lesson to assess students’ comprehension. Use the results to address any misconceptions or gaps in knowledge.Conclusion:Mr. Smith’s teaching approach for the “Global Warming” lesson is a good starting point. By incorporating more interactive activities, catering to varied learning styles, and implementing formative assessments, he can enhance student engagement and improve learning outcomes.四、教学设计题(40分)Question:You have been tasked with designing a lesson plan for a Grade 11 high school English class that focuses on t he theme of “Dreams and Aspirations.” The lesson is intended to help students think critically, enhance their vocabulary and writing skills, and encourage them to express their own dreams and aspirations. The specific objectives of the lesson are as follows:1.Students will be able to identify key vocabulary related to dreams and aspirations.2.Students will be able to analyze and discuss themes and messages in literary texts focusing on dreams and aspirations.3.Students will be able to write a short essay expressing their own dreams and aspirations.Design a detailed lesson plan with the following components:•Introduction (5-10 minutes)•Main Activity (25-30 minutes)•Conclusion (5-10 minutes)Resources:•Text excerpt from a literary work (e.g., Langston Hughes’ “A Dream Deferred”)•Writing prompts•Whiteboard and markers•Copies of the literary text•Computers or tablets with internet accessLesson Plan Outline:1.Introduction (5-10 minutes)•Greet students and introduce today’s topic: “Dreams and Aspirations.”•Pose a question to activate prior knowledge: “What are your dreams and aspirations for the future?” Allow 2-3 minutes for individualreflection.•Share a brief personal experience or anecdote to illustrate the significance of dreams and aspirations.•Explain the objectives of today’s lesson: to enhance vocabulary, analyze text, and express personal aspirations.2.Main Activity (25-30 minutes)•Vocabulary Activity:•Introduce key vocabulary related to dreams and aspirations (e.g.,aspiration, resolve, ambition, enlightenment).•Have students match definitions with each term or create a mind map on the board.•Provide examples of sentences using these words and elicit student participation.•Text Analysis:•Hand out copies of the literary text and give students 5-7 minutes to read it silently.•Conduct a close reading discussion (circling, underlining, or annotating relevant passages) to identify themes and messages related to dreams and aspirations.•Ask guiding questions to facilitate deeper understanding of the text (e.g., “What does the author mean by ‘a dream deferred’?”; “What are your thoughts on the theme of delayed dreams?”).•Essay Writing Activity:•After the text analysis, guide students through a brainstorming session to develop ideas for their essays.•Distribute writing prompts that encourage students to reflect on their own dreams and aspirations.•Spend about 10-15 minutes for students to draft their essays with the help of a mini-lecture on essay structure (introduction, body paragraphs, conclusion).。
北京航空航天大学博士研究生入学考试英语模拟试题一PART 1 Listening Comprehension (20 points) (略)PART II Reading Comprehension(30 points)Directions:There are four passages in the part. Each passage is followed by some questions or unfinished statements. For each of them, there are 4 choices marked A, B, C and D. Read the passages carefully and decide on the best choice. Then mark the corresponding letter on the ANSWER SHEET with a single line through the center.Passage 1Unless we spend money to spot and prevent asteroids(小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.Asteroids are bigger versions of the meteoroids(流星) that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.Buy $ 40 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap.Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400, 000 years. Sounds pretty rare-but if one did fall, it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us," says one scientist. "It's that simple."The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? "The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them," said a New Y ork Times article.21. What does the passage say about asteroids and meteoroids?A. They are heavenly bodies different in composition.B. They are heavenly bodies similar in nature.C. There are more asteroids than meteoroids.D. Asteroids are more mysterious than meteoroids.22. What do scientists say about the collision of an asteroid with Earth?A. It is very unlikely but the danger exists.B. Such a collision might occur once every 25 years.C. Collisions of smaller asteroids with Earth occur more often than expected.D. It's still too early to say whether such a collision might occur.23. What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?A. It sounds practical but it may not solve the problem.B. It may create more problems than it might solve.C. It is a waste of money because a collision of asteroids with Earth is very unlikely.D. Further research should be done before it is proved applicable.24. We can conclude from the passage that _.A. while pushing asteroids off course nuclear weapons would destroy the worldB. asteroids racing across the night sky are likely to hit Earth in the near futureC. the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetimeD. workable solutions still have to be found to prevent a collision of asteroids with Earth.25. Which of the following best describes the author's tone in this pass age?A. Optimistic.B. Critical.C. Objective.D. Arbitrary.Passage 2Believe it or not,optical illusion (错觉) can cut highway crashes.Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons (人字形)painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.Now the American Association Foundation for Traffic Safety in Washington D. C. is planning to repeat Japan's success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatest-curves, exit slopes, traffic circles, and bridges. Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bar.Chevrons, scientists say,not only give drivers the impress ion that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.26. The passage mainly discusses .A. a new way of highway speed controlB. a new pattern for painting highwaysC. a new approach to training driversD. a new type of optical illusion27. On roads painted with chevrons drivers tend to feel that .A. they should avoid speed-related hazardsB. they are driving in the wrong laneC. they should slow down their speedD. they are approaching the speed limit28. The advantage of chevrons over straight, horizontal bars is that the former .A. can keep drivers awakeB. can cut road accidents in halfC. will have a longer effect on driversD. will look more attractive29. The American Association Foundation for Traffic Safety plans to .A. try out the Japanese method in certain areasB. change the road signs across the countryC. replace straight horizontal bars with chevronsD. repeat the Japanese road patterns30. What does the author say about straight, horizontal bars painted across roads?A. They are falling out of use in the United States.B. They tend to be ignored by drivers in a short period of time.C. They are applicable only on broad roads.D. They cannot be applied successfully to traffic circles.Passage 3There are a number of formats for reporting research, such as articles to appear in journals, reports addressed to funding agencies, theses or dissertations as part of the requirements for university degrees, and papers to be presented at conferences. These formats differ from one another mostly in their purposes and the audiences whom they address. We will now briefly describe them.The journal article is a way of reporting research for professional journals or edited collections. The research is reporting in a brief, yet informative way, focusing mostly on the main features of the research such as the purpose, review of the literature ( often referred to as "background" ), procedures used for carrying out the research accompanied by tables, charts, and graphs, and interpretations of the results ( often referred to as discussion).The content and emphasis of the journal article will vary according to the intended readers (research or practitioners) and it is important for the researcher to be aware of the background and interest of the readers of the journal. Articles intended to be read by practitioners will emphasize the practical implications and recommendations of the research, while articles intended to be read by researchers will describe in detail the method used to collect data, the construction of data collection procedures, and the techniques used for analyzing the data. It is important for the novice researcher to be aware of the fact that articles submitted to journals go through a process of evaluation by experts who make a judgment and recommend whether they should be published or not.The thesis or dissertation is a format for reporting research which graduate students write as part of fulfilling the requirements for an advanced academic degree. The student is expected to describe in great detail all the phases of the research so it can be examined and evaluated carefully by the reader. Thus the thesis or dissertation includes the purpose and significance of the study, the rationale, a thorough review of the literature, detailed information as to the research tools and the procedures involved in their development, a description of data analysis and the results, and an interpretation of the results in the form of conclusions, implications, and recommendation. Thisdetailed description of the process of the research is needed to provide the professors with an indication of the student's ability to carry out research.The conference paper is a way of reporting research at conferences, seminars and colloquia. At such meetings research papers are usually presented orally. They are similar to the research 'article since research is reported in a concise, yet informative way, focusing on the most essential elements of the research. Handouts and transparencies can also accompany the presentations. As with the research article, here too, the content and emphasis of the oral report will depend to a large extent on the type of audience present at the meeting .and whether they are researchers or practitioners.31. The best title for this passage could beA. Types of Research ReportsB. Types of Journal ArticlesC. Writing of research ReportsD. Writing of Different Artic les32. The common aspect for the journal articles, theses and conference papers lies in thatA. they are all for the practitionersB. they are all to be read by researchersC. they are all for being publishedD. they are all forms of reporting research33. We can distinguish those research reports from each other mainly throughA. their writing style and lengthB. their aims and possible audiencesC. their presented places and timeD. their content and purposes34. Which of the following statements is NOT mentioned in this passage?A. Both journal articles and conference papers are reported in a brief and informative way.B. All the theses or dissertations and conference papers are reported in spoken languages.C. Both the journal articles and conference papers are influenced greatly by the intended receivers.D. The various formats of research reports may be presented in different ways.35. How can a professor evaluate a student's capability of implementing the research?A. By concentrating on the main factors like the purpose, background, procedures and discussion.B. By emphasizing the practical implications and recommendations of the research.C. By focusing on the detailed description of the process of the research such as the tools, procedures, the process of data analysis, the results, conclusions, etc.D. By noticing the detailed method used to collect the data, the construction of the data collection procedures, the techniques for analyzing the date and results, etc.Passage 4In recent years, many Americans of both sexes and various ages have become interested in improving their bodies. They have become devoted to physical fitness. The need to exercise has almost become compulsive with many persons who have a strong desire to be more physically fit.By nature, Americans are enthusiastic and energetic about their hobbies and pastimes. They apply this enthusiasm, and energy to jogging/running. As a result, there are running clubs to join andmany books and magazines to read about running.The desire to be physically fit is explained by a "passion" for good health. The high rate of heart attacks in the 1960s caused an increase on the part of the public in improving the human body.Middle-aged men especially suffer from heart attacks. Thus, they are one group strongly interested in more physical exercise. In fact, many doctors encourage their patients to become more physically active, especially those who have sedentary jobs. It is interesting to note that the rate of heart attacks began to decrease in the 1970s and it is still decreasing.Physical fitness currently enjoys a favored role in the United States. It is a new "love" that many Americans have cherished. Will it last long? Only time will tell or until another "new passion" comes along.36.

Write your translation on the ANSWER SHEET (2).The fact known to us is that war, different from what many people believe it to be, is not completely an outcome of" humanity". Otherwise,war and violence among people would exist in all the human history or ahnost all societies. However, this is not the truth. Archaeologists' investigation results seem to suggest that men lived quite a peaceful life long ago. For example, among ancient French cave drawings which were earlier than 10, 000 B. C., there were no pictures describing people fighting with each other. This indicates that, in that early period of mankind, fight among people was comparatively rare.In a certain way, this discovery is not surprising at all:in the world of animals, it's rare for one to prey on another of its own species. They do kill other kinds of animals, but not their own. Like most animals, the proportion of inner violence among early human beings was relatively small. Therefore, war is not the inherent outcome of humanity but that of certain social and cultural conditions.PART VI Writing(15 points)Directions:A.

Exercise 6此文甚难Some modern anthropologists hold that biologicalevolution has shaped not only human morphology butalso human behavior. The role those anthropologists Line ascribe to evolution is not of dictating the details of5human behavior but one of imposing constraints—ways of feeling, think ing, and acting that ―comenaturally in archetypal situations in any culture.Our ―frailties –emotions and motives such as rage,fear,greed, gluttony, joy, lust, love—may be a very mixed 10assortment, but they share at least one immediate quality: we are, as we say, ―in the grip of them.And thus they give us our sense of constraints.Unhappily, some of those frailties—our need for ever-increasing security among them—are presently15maladaptive. Yet beneath the overlay of cultural detail, they, too, are said to be biological in direction, andtherefore as natural to us as are our appendixes.

Turner wrote in the 1890‘s that the agrarian discontent that had been developingsteadily in the United States since about 1870 had been Line precipitated by the closing of the internal frontier--that is, 5the depletion of available new land needed for further expansion of the American farming system. Actually,however, new lands were taken up for farming in theUnited States throughout and beyond the nineteenthcentury. The emphasis of the presumed disappearance of10the American frontier obscured the great importance of changes in the conditions and consequences of international trade that occurred during the second half ofthe nineteenth century. Huge tracts of land were beingsettled and farmed in Argentina, Australia, Canada, and in 15the American West, and these areas were joined with one another and with the countries of Europe into aninterdependent market system. Consequently, agrariandepressions no longer were local or national in scope, andthey struck several nations whose internal frontiers had20not vanished or were not about to vanish.

I have been increasingly impressed with the functional similarities between insect and vertebrate societies and less so with the structural differences that seem, at first glance, to constitute such an immense gulf between them. Consider termites and macaques. Both form cooperative groups that occupy territories. In both kinds of society there is a well-marked division of labor. Members of both groups communicate to each other hunger, alarm, hostility, caste status or rank, and reproductive status. From the specialist‘s point of view, this comparison may at first seem facile—or worse. But it is out of such deliberate oversimplification that the beginnings of a general theory are made.

Most Bluestockings did not wish to mirror the salonnieres; they simply desired to adapt aproven formula to their own purpose—the elevationof women‘s status through moral and intellectualtraining. Differences in social orientation and back-10ground can account perhaps for differences in the nature of French and English salons. The Frenchsalon incorporated aristocratic attitudes that exaltedcourtly pleasure and emphasized artistic accomplish-ments. The English Bluestockings, originating from a 15more modest background, emphasized learning and work over pleasure. Accustomed to the regimented life ofcourt circles, salonnieres tended toward formality in theirsalons.

Her subjects appear to beacquain-tances whom she has asked to pose; she hascapturedLine both their self-consciousness and the spontaneity of their 5everyday activities, the depiction of which characterizes genre painting. But genre painting, especially when itportrayed members of the humblest classes, was neverpopular in eighteenth-century France. The Le Nainbrothers and Georges de La Tour, who also chose such10themes, were largely ignored. Their present high standing is due to a different, more democratic political climate and todifferent aesthetic values: we no longer requireartists to provide ideal images of humanity for our moral edification but rather regard such idealization as a falsifi-15cation of the truth. Duparc gives no improving message and discreetly refrains from judging her subjects. In brief,her works neither elevate nor instruct.

Most striking among5the many asymmetries evident in an adult flatfish is eye placement: before maturity one eye migrates, so that in anadult flatfish both eyes are on the same side of thehead. While in most species with asymmetries virtuallyall adults share the same asymmetry, members of the10starry flounder species can be either left-eyed (both eyes on the left side of head) or right-eyed. In the watersbetween the United States and Japan, the starry flounderpopulations vary from about 50 percent left-eyed off theUnited States West Coast, throug h about 70 percent15left-eyed halfway between the United States and Japan, to nearly 100 percent left-eyed off the Japanese coast.Biologists call this kind of gradual variation over ac ertain geographic rang a ―cline and interpret clinesas strong indications that the variation is adaptive, a20response to environmental differences. For the starry flounder this interpretation implies that a geometricdifference (between fish that are mirror images of oneanother) is adaptive, that left-eyedness in the Japanesestarry flounder has been selected for, which provokes a25perplexing questions: what is the selective advantage in having both eyes on one side rather than on the other?The ease with which a fish can reverse the effect of the sidedness of its eye asymmetry simply by turningaround has caused biologists to study internal anatomy,30especially the optic nerves, for the answer. In all flatfish the optic nerves cross, so that the right optic nerve isjoined to the brain‘s left side and vice versa. Thiscrossing introduces an asymmetry, as one optic nervemust cross above or below the other. G. H. Parker35reasoned that if, for example, a flatfish‘s left eye migrated when the right optic nerve was on top, therewould be a twisting of nerves, which might bemechanically disadvantageous. For starry flounders, then,the left-eyed variety would be selected against, since in a 40 starry flounder the left optic nerve is uppermost.The problem with the above explanation is that the Japanese starry flounder population is almost exclusivelyleft-eyed, and natural selection never promotes a purelyless advantageous variation.

中国卫生产业·第八卷·第三期·上 27经椎弓根螺钉具有固定可靠及固定节段少等力学优势,已被广泛地运用于胸椎及腰椎的内固定中。
但由于中上胸椎椎弓根细小,植入时容易损伤周围重要组织。
经肋椎关节固定作为胸椎固定的必要补充方法成了近期研究的热点,本研究针对国人中上胸椎不同节段经肋椎关节和椎弓根固定通路进行测量及对比研究,旨在为经肋椎关节固定技术在临床的应用提供参考数据。
1 资料与方法1.1 一般资料选择16具(男11具、女5具)正常成人防腐尸体胸椎骨,检查各标本无明显脊柱损伤性疾病及结构异常。
1.2 方法对T1~T8共128个椎体256个肋椎关节及相应椎弓根进行以下测量:(1)肋椎关节和椎弓根后缘骨皮质到椎体前缘骨皮质的距离;(2)肋椎关节、椎弓根轴线与椎体矢状轴的夹角(e角);(3)肋椎关节轴线与椎体水平面的夹角(f角)。
采用SPSS 16.0软件进行统计学分析。
2 结果T1~T8相同节段经肋椎关节与经椎弓根固定的钉道长度及e角的测量数据比较均有统计学意义(P <0.05),见表1、2。
经肋椎关节固定的钉道长度>经椎弓根固定。
T1的钉道长度最短,T1~T8逐渐增大。
肋椎关节的e角>椎弓根。
T1的内倾角度最大,向下逐渐减小。
不同肋椎关节f角的变化不大,总体在-3~3°之间,见表3。
3 讨论胸椎椎弓根窄细,形态上横径短于上下径,以T4~T6节段最窄,平均横径<5mm。
Vaccaro等报道,因上胸椎椎弓根较细,临床上有41%的椎弓根钉误置率,其中23%偏内侧,18%偏外侧,所以医源性胸椎椎弓根骨折及出现血管、脊髓损伤等并发症时有发生。
虽然减少椎弓根螺钉的直径可以降低并发症,但螺钉的固定强度也会受到影响。
Willett K等用完整的人椎体进行常用的椎弓根螺钉的拔出试验表明,直径越大的螺钉拔出力学强度越强。
而经肋椎关节固定作为一种新的固定方法穿钉时不必要求椎弓根钉在椎弓根内,椎弓根和肋骨可为螺钉提供足够的安全路径,因此可以使用直径更大的螺钉来增加固定强度。

.An Exploratory Comparison of the Roles of Representations in Face to Face andOnline Collaborative LearningDaniel D. Suthers, Christopher D. Hundhausen, and Laura E. GirardeauLaboratory for Interactive Learning TechnologiesDepartment of Information and Computer SciencesUniversity of Hawai`i at Manoa{suthers,hundhaus,girardea}@AbstractThe paper reports an empirical study comparing the role of discourse and knowledge representations in face to face versus distance collaborative learning. The study reported in this paper compares Proximal (face to face) with Distal (synchronous collaboration via networked software) conditions. Two competing hypotheses were evaluated: (1) The influence of representations in the Distal condition could be weaker because of the lack of implicit "taken as shared" that results from working together in front of a physically shared display, and because of the greater difficulty of utilizing the representations as a resource for conversation through gesturing. (2) The influence of representations in the Distal study could be stronger because participants may rely more on them for their communication in the absence of face-to-face communication. The quantitative data supported the second hypothesis, while other observations supported the first hypothesis. A synthesis is offered.1. IntroductionOnline collaborative learning intrinsically requires that learning be mediated by external representations. These representations may include discourse representations (e.g., the chat rooms and threaded discussion tools by which learners and teachers communicate in their native language [5], disciplinary representations such as visualizations and designed artifacts (e.g., [7, 11]), and symbolic representations of one's theories and reasoning that we will term knowledge representations (e.g., [16]). Unlike the spoken discourse of proximal collaboration, the discourse in distance collaboration takes place in a software-supported representational medium. Given the total reliance on external representations in online collaborative learning, it is appropriate to ask how these representations should be designed to facilitate collaboration.Our prior work on external representations in face-to-face collaborative learning situations has shown that differences between representational notations can translate into differences in the focus of learners' discourse and collaborative activities [14, 15]. In these studies, learners were asked to solve a problem in science or public health, presented as a sequence of information pages, while utilizing one of several experimentally manipulated alternate representations (text, graph, and matrix) for recording data, hypotheses, and the evidential relations between them. Differences in discourse focus were predicted according to the kinds of information that the representations prompt one to seek, and the information needs that become salient as one constructs a representation [12]. We found that visually structured and constrained representations can provide guidance for collaborative learning that is not afforded by plain text. However, more guidance is not necessarily better. For example, the matrix representation prompted for consideration of irrelevant relationships as well as relevant ones. The graph representation – “evidence maps” – provided guidance without excessive prompting. Benefits of graphical evidence maps have also been observed in a classroom setting [17].This paper reports our first extension of this work to a study of how representations might influence collaboration in distance collaboration situations. We begin with a comparison of face-to-face and online collaboration, since we have studied the former in great detail and need to understand how online collaboration differs. This is not a new topic. Extensive prior research has compared performance of face-to-face collaborators to performance of users of various forms of technology-mediated communication (including audio, video, and various forms of computer mediated communication). Studies of synchronous problem solving generally show degradation of both problem solving performance and interpersonal communication due to the reduced “bandwidth” or available modes of interaction associated with technology-mediated communication [4.9], although factors extrinsic to the technology itself may play a role[19], However, it would be overly simplistic to treat technology mediation as an atomic variable, or to evaluate this variable apart from task characteristics or objectives [2]. Indeed, an extensive literature on asynchronous online learning typically concludes that there is no significant difference in learning outcomes as compared to traditional classroom learning [10].It was not our intent to replicate or test these results. Rather, we sought to understand how the roles that representations play might change between face-to-face and online collaboration in order to understand how our previous work might inform the design of online learning environments. Our previous study provided a baseline understanding of how a representation such as Graph is appropriated and used by learners and influences learner’s activities in a face-to-face setting. Would the role of Graph be similar when interaction is online, with a textual “chat” tool replacing spoken language?The conditions compared in this study are termed Proximal (face to face) and Distal (synchronous collaboration via networked software) in analogy to the medical terms. We approached this work with two hypotheses in mind. At the outset of the study we considered these hypotheses to be competitors with each other, but had no prediction concerning which would be the dominant factor.(H1) The “Co-present Affordances” Hypothesis: The influence of representations in the Distal conditionwill be weaker because some key representationalaffordances for collaboration depend on workingtogether in front of a physically shared display,including implicit “taken as shared” context and useof the representations as a resource for conversationthrough gestural deixis (referring to something inthe extralinguistic context [3]).(H2) The “Appropriation for Communication”Hypothesis: The influence of representations in theDistal study will be stronger because participantsmust place greater reliance on those representationsfor their communication to compensate for theabsence of face-to-face communication.The results show that the distribution of activity was quite different between the Proximal and Distal groups. Quantitative analysis of this distribution largely supports the second hypothesis. However, other observations indicated that influences predicted by the first hypothesis are also manifest in different aspects of participants’ activity. We discuss alternate explanations for these results, and broader implications for the nature of collaborative learning with knowledge representations. 2. DesignThe present study built on a prior study that compared three representations: matrix, graph, and text [14, 15]. We elected to implement a synchronous distance collaboration version of the graph condition and to compare performance of participants in this condition with those in the previous proximal (face to face) graph condition. Both groups were given the identical task of exploring an unsolved “challenge problem,” presented as a series of textual web pages, by recording data, hypotheses, and evidential relations as they encountered them.2.1. ParticipantsTwenty (20) students were recruited in self-selected, same-gender pairs, out of introductory biology, chemistry, physics, and computer science courses at the University of Hawai`i. Participants were age 25 years or younger and native English speakers. Participants were paid a $25 honorarium. Pairs of participants were randomly assigned to treatment groups.The unit of analysis was the pair (all individual scores were aggregated for each pair). We used pairs rather than larger groups because a pilot study showed that participation of students is reduced when there are more than two students at a single keyboard and monitor in the Proximal condition. We used same-gender pairs because we observed censoring problems with mixed-gender pairs in our pilot study. We used self-selected pairs (friends) to avoid the additional social familiarization that would have been required between strangers.2.2. MaterialsPairs of participants used one of two different versions of software for representing data, hypotheses, and evidential relations. The Distal version is shown in Figure 1. Participants used the upper right hand window to move forward through a sequence of 15 pages that presented information relating to the cause of a mysterious neurological disease on the island of Guam. The left-hand window contained a graphical tool for constructing representations of the data, hypotheses, and evidential relations participants gleaned from the information pages on the right. The graph tool is based on Belvedere [16], and enables one to build a graph of nodes expressing data items and hypotheses, and links labeled “+,” “-,” or “?” representing evidential relations.Figure 1. Experimental software with chat toolThe software for the Distal condition provided a simple chat tool in a window in the lower right (which was not present in the Proximal version). Messages typed into a chat entry box were sent to both participants’ shared chat displays once the message was completed and the “send” button was pressed.Both versions of the software support deixis by causing the color of objects to change when one passes the cursor over them, enhancing the deictic value of the cursor. The Distal version of the software replicated these color changes to the remote display. In this manner we attempted to support the use of the knowledge representation as a resource during conversation in the Distal as well as Proximal condition.2.3. ProcedureAt the beginning of the learning session, participants (co-present in both conditions) were given a brief (10-minute) introduction to the software they would be using. At the conclusion of this introduction, one of the Distal participants was led to a different room containing an identical computer setup. Then, in both conditions, participants worked on a warm-up problem (on mass extinctions) that was unrelated to the main problem, so that they could become acquainted with the software and the information-recording process. After 12 minutes, participants were instructed to stop work on the warm-up problem, and to move on to the main problem (on the neurological disease). Participants were given as much time as they needed to explore all 15 pages on the main problem. When they reached the page that informed them that there were no more pages left, the experimenter asked them whether they felt they were done. Some participant pairs decided that they wanted to work further on their representations; they were given as much additional time as they needed. Once a participant pair declared themselves done, the experimenter instructed them to turn off their computer screen(s), at which point they were given 20 minutes to individually complete a multiple-choice post-test. (We did not have any specific predictions about the outcome of this test, but administered it to keep the conditions the same as Proximal.) At the conclusion of this test, the Distal participants were brought back together. In both conditions, participants then were allotted 30 minutes to complete a collaborative essay using a word processor. 3. ResultsPosttests of memory for factual information showed no significant difference between Proximal and Distal groups. We are currently analyzing the essays. In this paper we focus on a categorical analysis of the verbal and representational acts of the participants.3.1. Data AnalysisVideo/audiotape of the proximal sessions were transcribed by hand. The software generated transcripts of the distal sessions automatically. Transcripts were divided into “segments,” each consisting of a verbal or typed utterance (multi-propositional utterances were divided into individual segments) or a change to the representation. See [14] for details of the coding used. Then we performed a content analysis of participants’ learning processes by coding all segments in the 20 transcripts into the following mutually exclusive “topic” categories:• Evidential relation. These segments consider whether data and hypotheses are consistent, that is, whether a data item supports or conflicts with a hypothesis. For example, the segment “That’s for the genetics hypothesis” would be coded as evidential relation—consistency.• Epistemic classification. These segments classify information as either empirical or theoretical—that is, as either data or hypothesis. For example, the segment “Let’s make a hypothesis about toxic drinking water” would be coded as epistemic classification. Likewise, in the graph software, the action of clicking on the “create data” button would be coded as epistemic classification.• Hypothesis statement. This coding was applied when participants stated a hypothesis concerning a possible explanation for the disease without labeling it as a hypothesis (e.g., “Might be a combination of both”). • Metacognitive. In these segments, participants step back and either assess what they know so far (e.g., “We know that they used the drinking water for the fadang, to prepare the seeds”), or identify information that is needed but lacking (e.g., “See, but it doesn't say that these admission records are patients that have the disease”).• Warrant. These segments provide justification for an evidential relation previously cited. For example the second half of, “That supports the aluminum hypothesis, because Irian Jaya was found to have higher than normal levels of aluminum in the soil”would be classified as a warrant.• Tool talk. These segments discuss some aspect of the software. Participants might, for example, ask how to complete some specific task with the software (e.g., “How do you get this out of the way?”); they might complain about the software (e.g., “Oh my, what's wrong with this thing?”), or they might share their emerging understandings of how the software works(e.g., “If we click on this we can see it”).• Domain talk. These segments discuss the domain of the science problem that participants are exploring.This category had the lowest precedence: we coded segments into this category only if they could not be coded into one of the five categories above. For example, “Northern Guam is a low limestone plateau” would be coded as domain talk.• On-task. These segments did not fall into any of the first six categories, but could still be considered on-task. For example, “Let’s go to the next page” would be coded as on-task. • Off-task. These segments were deemed to be unrelated to participants’ learning task. For example,“What did you do last night?” would be consideredoff-task.In addition, we coded topic segments with “modifier” categories, according to whether they were• Verbal or representational—spoken or expressed in the chat tool, versus represented using the software;• Recited or non-recited—quoted verbatim from the information pages, or not quoted;• Introduced or repeated—the first occurrence of an idea within a given conversation, or a reintroductionof an idea already brought up within a givenconversation.In order to verify the reliability of our coding system,we had two independent analysts code 20% of the transcripts. With respect to the eight mutually exclusive “topic” categories, our analysts attained 89% overall agreement, and 0.86 kappa. With respect to the modifier categories, agreement levels ranged from 88% (0.77 kappa) for introduced vs. repeated, to 100% agreement (0.99 kappa) for verbal vs. representational. We decidedthat our coding system was sufficiently reliable, and had a single analyst code the remaining 80% of the transcripts.3.2. Quantitative ResultsThe distribution of the codes across treatment groups is shown in Table 1. There were many more segments in Proximal than in Distal, this difference being attributableto larger counts in most categories, particularly in domaintalk and other on task talk, although Distal participants engaged in more epistemic classification and hypothesis statement acts.Table 1.

We performed statistical tests on the percentages rather than the raw counts to control for differences in verbosity between groups, although raw counts will be consulted inour interpretation of the results (next section). The moststriking differences in the percentages are in domain talk, epistemic classification and (to a lesser degree) evidential relation. The Proximal participants engaged in a greater percentage of domain talk, which is reflected in the rawcounts as well. Distal participants engaged in a greater percentage of epistemic classification, evidential relation and hypothesis statements. The raw counts for evidential relation are actually very similar.For the purposes of this study, “verbal” means spoken in the Proximal condition and use of the chat tool in the Distal condition; while “representational” means use of the graph tool in both conditions. Table 2 compares the two conditions with respect to their counts of On-Task, Non-Recited segments. An independent samples t-test indicates that the Proximal condition had significantly more verbal segments than the Distal condition (df = 1, T = -2.77, p = 0.0126); no other statistically significant differences were detected.Table 3 shows both raw counts and percentages of the On-Task, Non-Recited segments listed in Table 2. (Therefore the percentages differ slightly from those in Figure 2, which are of the total number of segments).To test for statistically significant differences, we compared each Proximal/Distal pair of percentages using a Kruskal-Wallis ANOVA. As indicated in Table 2, differences between all of the values shown except for the last row are statistically significant at levels ranging from p=.0001 to .05. The overall pattern is as follows. The Proximal participants engaged in a greater number of on-task, non-recited acts overall, with most of these being spoken. Distal participants engaged in a greater percentage (although approximately the same raw count) of acts concerned with relations of evidence. These acts occurred more in the verbal (spoken) medium in Proximal, and in the representational (graph) medium in Distal. Similarly, Distal participants engaged in a greater percentage of epistemological classification acts, these being primarily in the representational medium (as opposed to the chat tool). However, Proximal participants engaged in considerably more talk about domain attributes and relationships.3.3. Qualitative ObservationsExamination of the transcripts during analysis led to the following qualitative observations concerning the timing and purpose of discourse related to the representations. We offer the following impressions and examples to provide the reader with a feel for the interactions, while recognizing that formal analysis and testing would be needed to substantiate our impressions.For Proximal participants, the graph functioned as a stimulus to discourse, and the representations were also treated as an external product of the discourse. Agreement tended to be forged before representations were made, as in the following example leading up to the events at time 10:42. The graph also served well as a deictic resource. Coordination between discourse mode and diagrammatic media was easier for Proximal participants because they could simply point to an item on the screen or click their cursor when determining a relationship or discussing an issue:*L: Actually, you can’t say that this goes to that, though. <points to D5 & H1>*R: Why?*L: Because other people drink from the water too, yeah?*R: Like who?*L: The navy people.*R: Maybe they, maybe they got their stuff from somewhere else.*L: And then this will go against the idea of this. <points to D7 and H1>*R: Except when they get here, though.<cursor at D9>*L: But then this will go with this, you know what I’m saying? <points to H1 and D9> *R: Yeah, but this would make this whole thing go with it, though.<sweeps cursor from D9 to H1 across right hand row of boxes>Because the seeds are soaked in the water, it makes the seeds part of the water hypothesis.If they weren’t soaked in the water, thenit would be <inaudible>.*L: This lady thinks it could be just from the seeds, though. <points to D8>*R: I know, but like a dragon could have farted on them and caused the disease!<laughs>10:42:42 D07--D06 ADDED: FOR10:42:48 D08--D07 ADDED: FOR10:42:54 D09--D08 ADDED: FOR10:44:00 H01--D05 CHANGEDTO: QUESTIONI mean, like this one, what naval people was it? Was it American naval?*L: Because, this just says that Guam is part of U.S. territory.*R: America, but I mean, like, do they have their own navy or something?*L: No.*R: Well, then if it’s American naval, then maybe they have their water source or something. I’m sure they don’t drink water out of the stream. They probably clean, I’m sure they go through a cleaning process if they live on a naval base.*L: What about the other people? Guamisn’t…If it’s part of the U.S. territory, I would think that they would have enough, at least adequate facilities to treat water.*R: I don’t know.*L: Go to the next one.For Distal participants, the graph also functioned as a stimulus to and product of discourse, but was also used to a much greater extent as a discourse medium. Discourse often took place within the graphs in two ways: (1) participants proposed new items or relations by creating them in the graph medium, whereupon chat focused on approval or disapproval; and (2) participants used the graphical representation in place of the chat tool to send a message that was deleted. For instance, one pair posted on-task questions, such as “What should we do now?” and “I don’t know what the answer is” in the graph rather than in chat. Another pair posted domain questions such as, “What is causing this disease?” and linked them up with data and hypothesis shapes. At times the graph was used in a manner peripheral to discourse, when a participant independently modified the graph amidst unrelated chat discussion (the graph was rarely modified without related talk in Proximal). This created a need for the removal of duplicate or similar items created independently by each partner, and negotiation of which item would be removed.The following example, although far more verbose than most Distal exchanges, serves well to illustrate these typical characteristics of Distal discourse. Instead of discussing what to add to their graph in advance, the pair proposes new items or relations by first representing them independently of one another in the graph medium. Chat then focuses on short comments of approval or disapproval and negotiation about duplicates:*P6.1Changed to page 1: Northern GuamH01 ADDED: [Blank]*P6.2D01 ADDED: Water collects calcium as it seeps through limestone*P6.1H02 ADDED: Limestone may be the cause ofthe disease ALS-PDD01--H02 ADDED: FORH01 DELETED: [Blank]*P6.2Changed to page 2: Southern Guam*P6.1D02 ADDED the drinking water in Guam is collected from wells that have water that seeps through limestone D02--H02 ADDED: FORChanged to page 2: Southern Guam*P6.2D01 DELETED: Water collects calcium as it seeps through limestone*P6.1CHAT Why did you delete it. didn’t think it was relevant?*P6.2CHAT Its the same thing you just said*P6.1CHAT K*P6.2CHAT Except for the calcium partD03 ADDED: The water collects calcium as it seeps through limestone*P6.1D04 ADDED: Drinking water contains high levels of aluminum from streamsD04--H02 ADDED: AGAINSTH03 ADDED: Aluminum in drinking water is cause of ALS-PDH03--D04 ADDED: FOR*P6.2H04 ADDED: ALS-PD is a form of mineral poisoningD04--H04 ADDED: FOR*P6.1D02--H04 ADDED: FORCHAT Does that look alright*P6.2CHAT Ya i guess so*P6.1CHAT Moving onOvert discussion of alternate hypotheses in Distal was often concentrated at the end of the session, after all representations had been made and participants were urged to come to a final conclusion.

DiscussionRecall that The “Co-Present Affordances” hypothesis (H1) predicts that representational guidance is less effective when participants are not co-present, because some key mechanisms through which representations support collaboration are less effective at a distance. Therefore, we might expect that the graph’s prompting for certain categories would be less influential in Distal than in the Proximal condition. The “Appropriation for Communication” hypothesis (H2) predicts that more of the communicative activity will take place in the knowledge representation medium as it is appropriated to make up for the loss of spoken “bandwidth.” Therefore we would expect to see either more communications using categories provided by the representations overall, or a shift of these categories into the representational medium at the expense the verbal medium in Distal.The quantitative results concerning categories of talk largely support the second hypothesis. To begin, a shift in emphasis on verbal versus representational activity is seen across Proximal and Distal, respectively. Participants in the Distal study represented the epistemic classification and evidential relation categories over two times more than Proximal participants. However, Proximal participants discussed epistemic classification nearly five times more than Distal participants, and evidential relation categories over nine times more than Distal participants. Clearly, Distal participants are relying on the graph for more of their communications. Yet we need to ask whether this change is universal to all communications or sensitive to the specific categories supported by the graph.A greater percentage of acts in the Distal condition were concerned with categories provided by the graph representation (epistemic classification and evidential relations). In the case of evidential relations, the counts were similar, so this reflects a difference in the denominator: perhaps the same amount of evidential thinking is taking place in the context of less overall talk. However, a greater number of the Distal evidential relation acts are classified as “introduced,” that is, as a reintroduction of the topic of evidence rather than as a continuation of an ongoing discussion of evidence. Given that many of these acts are representational, Distal participants may be using the graph medium to propose evidential relations, resulting in less overall talk but many representational introductions of evidential relations. Both numerically and in percentage, there were many more epistemic classifications in Distal. This result also supports H2, and is consistent with our qualitative interpretation that new objects are being created in the graph representation to propose ideas (each object creation event is also coded as a classification event).The claim that the specific affordances of the graph influence which relations are discussed in Distal is further supported by a converse result. The Proximal condition discussed more domain talk; indeed, domain talk made up nearly five times more of the total utterances than did Distal domain talk. The graph provides no support for domain attributes and relations, so the extra work required to type concepts and propositions of an unfamiliar domain in chat would have impacted these communications more than those concerned with categories that are supported by the graph. This observation is also consistent with H1: without co-presence, participants cannot as easily refer to previously represented domain concepts through gesturing.The hypothesis statement category, which is coded when participants proposed hypotheses without classifying them as such, poses a potential challenge to H2’s claim that Distal communications increase specifically in categories supported by the graph. Hypothesis statement, although not specifically supported by the graph, occurred twice as often in Distal discourse. However, most of the Distal segments in this category occur after the last page, when participants are asked to come to a final conclusion. Perhaps Distal participants are compensating for their lack of domain talk by making domain hypotheses more explicit at this stage. As predicted by H1 and seen in our transcript examples, activity is less tightly coordinated in Distal, so we would expect a lack of implicit agreement on the hypotheses at the end of the problem solving session.。
