Unit 2 HeroesLesson 1 Modern HeroesPart 1 Analysis of Teaching materialThe topic of this unit is Heroes, including national heroes, history makers, sports stars and superhero. Different fields have different heroes.The first lesson is about national hero Yang Liwei’s first journey with Shenzhou V to the outer space.The lesson not only tells the first manned spaceship’s movement from lift-off to landing, but also trains the students’ English learning abilities including reading, writing and speaking abilities. The senior students have built the basic foundation to learn English.They are more mature than before, so they are able to analyze some primary materials.They are just lack of chances to practice and courage to express their ideas.According to the new standard curriculum and the syllabus, after analysis of the teaching material and the students, I think the teaching aims are as follow:1. Knowledge and skill aims:a. To practise skimming and scanning skills to get a general idea of the text and find answers to some specific questions.b.To practise intensive reading in order to get the main idea of each paragraph and work out the meaning of the new words, new phrases and key structures.c. To practise writing skills with the new words, new phrases and structures.d. To improve oral English.2.Process and method aims:To train the students’ self-learning and cooperative ability.3.Emotion and moral aims:To understand the hardships during the development of the space exploration.The important point of the lesson is how to work out the meaning of the new words, new phrases and key structures.The difficult point is how to make good use of the new words, new phrases and key structures in proper situation. In order to stress the important point and break through the difficult point, I will adopt some teaching methods as follow.Part 2 Teaching methodsIn the teaching process, communicative approach and task-based language teaching methods will be adopted. The new standard curriculum propose that the students should be the real master of the class, and put emphasis on their probe ability and cooperative ability. So many chances will be provided to train their abilities.Part 3 Studying methods.Students of this stage are quick in thought and they are eager to show what they know. They have a certain self-learning abilities which needs more practice. A good teacher will act as a director, a guider, a helper to make the students the real master of the class. The main studying methods are individual work, group work, practise and communication strategy. The students’ reading, writing and speaking skills will be improved by the practice.Part 4 Teaching procedureSeven steps will be taken in the teaching procedure.Step 1 Lead-inThe most important purpose of this step is to stimulate the students’interest. I will show some pictures of Shenzhou Ⅸand the first female astronaut Liu Yang in our country. Then I will ask them whether they know the first male astronaut and the name of the spaceship in our country. After their answering, I will show more background of Shenzhou V and Yang Liwei. And the students should make a prediction of the content of this article. These information and questions will arouse the students’ curiosity about the content of this lesson.Step 2 Skimming readingTo train the students’ skimming reading skills, I will give 3 minutes to finish the first reading of the article. And they should get the general idea of the article and check whether their prediction is right. Circle the words that remarks the course of the spaceship’s movement in 2 minutes.Step 3 Scanning readingTo train the students’scanning reading skills and cooperative ability, we will read through 5 questions together. And then I will divide them into five groups. Each group will take charge of 1 question. They should scan the article and find the answer to the question. With the impression got in the first and second reading, they will get the answers. To train their expressing ability, they should share with the group and then with the whole class.Step 4 Intensive readingThis is the most important part of the lesson. The students will be the real master of the class in this step. The students should finish some individual work to improve the self-study ability, and group work to get cooperative abilities.Individual work: read the article carefully by themselves, and generalize the main idea of each paragraph and match the given six headings with the paragraphs.Group work: to share the main ideas and answers with the group, and choose the best one.To find out the new words, new phrases, key structures and work out the meaning by meaning-prediction in the context. Sometimes they need guess the meaning by reading again and again. As a director, I will make necessary complements when they get confused and there is language notes missing.Step 5 Post-reading practice.To learn is to use. After reading, Students need practices. N Brain-storming is used in this step to train the students’ imagination, writing and communication abilities. First, they should write a small passage with the new words, new phrases or key structures they conclude. They will share with the group and choose the best one to share with the class. Second, they should make expansion of the expression with the verbs and nouns. The verbs are given: collect, complete, express, let outStep 6 SummaryThis step is to consolidate the knowledge they just learned. The students will speak out the expressions and key words learned in this period. They should get a clear map of this article in their mind. The course of the spaceship’s movement- the main idea of each paragraph-the useful words and structures in the article-the application of the new words have learned.Step 7 HomeworkTo train the students’writing skills and their morality, the students should finish the reading of Space Heroes on page 32, and they should write down their feelings after reading the passage.Part 5 Blackboard designBlackboard design should be brief and attractive to the students’attention. And the blackboard design should give the students the main teaching points of the lesson. The blackboard design of this lesson is as follow:Unit2 Lesson 1 Modern heroes1.The course of the spaceship’s movement:The remarking words:2.The language notes: separate from and divide intoThe key structure: when...be doing, something happened.3.Brain-storming: collect+nouns.CompleteNo matter which step is taken, the purpose is to train the students’learning abilities and the teacher’s teaching skills. Both students and the teacher will get helped in the whole teaching process.That’s all. Thank you.。
