1、Unit 7 Whats the highest mountain in the world? （Section B 1a-1d）Teaching Design . . The Guiding Ideology and Theoretical Basis As we know that the principles of communicative class can be reached only when teachers create appropriate experiential scenarios. And the teaching unceasingly establishes

2、the classroom instruction situation, take the question as the master line, guides the student to cause suspicion, the question and answer, stimulates the student creative thought ability, is helpful smoothly achieves the teaching goal to the teacher. Psychology demonstrate, pleasant learning can als

3、o prove to fully arouse students interest in learning, enthusiasm and play the potential of students, thus increasing memory effect. And the training aim in English teaching is to cultivate students not only to master fundamental language skills, but also to use foreign language to achieve communica

4、tion. Let the student carry on the spirited language practice, enhances enthusiasm which the student studies. The goal of Go for it! is to make language learning motivating and successful through a step-by-step progression that builds confidence and lead to open-ended activities where students can a

5、ctively relate learning to their personal lives. . . Analysis of Materials Section B in Unit 7 has changed the topic from the comparison of nature and culture to animals. This part introduces something about elephants, pandas and panda research base. Through listening, speaking, reading, writing and

6、 other activities, the teacher can guide students to learn more comparative sentence structures. On the one hand, the contents in la-le consolidate the fact description with numbers. On the other hand, it expands more sentence patterns such as multiples to compare two different things. In activity 1

7、a, it shows some information about an elephant and a panda, and students are supposed to compare them with comparative sentence patterns. Meanwhile, it also foreshadows the groundwork for later listening. In activities 1b and lc, the listening material is mainly about the description of baby pandas

8、with length, weight, color and so on. In activity 1d, students are supposed to take turns telling something about pandas. In emotional education, the teacher should guide students to understand why and how to protect the endangered animals such as the giant panda.After much deliberation, I design th

9、is language learning, speaking and writing class based on the latest English Curriculum Standard. . Analysis of Students Since this is the second part of this unit for Grade Eight, the students have been stimulated to talk about the comparison of nature and culture. And Ss also could describe pandas

10、 based on what they saw at the zoo. However, not all of them have known the details, especially the baby panda. In emotion education part, the teacher can guide them to think why and how to protect them. In order to help students grasp the key points well, I will use the following steps. First, the

11、clear learning objectives help students to monitor their own learning. Next, provides step-by-step language support for students to follow. Then, activities encourage learners to contribute their own ideas and feelings and to be active in class, and develop studentslanguage system. . Teaching Object

44、ntages Advantages In this teaching period, the teacher had an excellent design according to the contents, the students and the New English Curriculum Standard.Here is what the teacher did well. 1. The learning objectives were set really useful and efficacious. Ss could understand and achieve them ea

45、sily. 2.At the beginning, the teacher led Ss review what they had learnt in this unit and then changed the topic from the comparison of nature and culture to animals naturally. 3. The teacher came up with an acceptable way to present multiples by a mathematic form, and tried to present the new sente

46、nce pattern by drills, without more explanations. 4. Before listening, the teacher had Ss have a prediction first according to their experience. Thats a good way to develop information literacy of students and overall ability to learn. 5. The video was chosen successfully. Ss could better understand

47、 the description through vision directly. 6. The conversation brought Ss more source material for writing. They just needed to pick up the useful sentences to make up their own writing. Meanwhile, it also showed whether they comprehended the original meanings nicely and thoroughly. 7. “How can we pr

48、otect the pandas?” Thats the emotion education part of this class. It was the best time when Ss considered pandas with great interest to discuss the protection. Ss could share their ideas in groups. 8. The ending served as a connecting link between the preceding and the following. Disadvantages 1. Maybe the teacher should show the phonetic of the new words and let Ss recognize and read by themselves. 2. Before writing, the teacher should give specific requirements, like they must use the comparative sentence pattern with time. The teacher could check if Ss mastered it well at the same time.
