Som e students are not active and confident in class, some students have trouble in reading, an d they are poor in reading strategies, so I’ll have students study in a relaxed atmosphere.Part 3 Teaching Methods(说教法)As we know, a good teaching method requires that the teacher should help students develop good sense of the English language. For achieving these teaching aims and after t he analysis of the teaching material and teaching aims, I will use the following methods a ccording to the modern social communication teaching theories:(1) Interactive Approach(2) Task-based Language Teaching(3) Students independently inquiryPart 4 Studying Methods (说学法)According to the situation of the students and teaching aims. I’ll teach Ss how to be successful language learners by these ways:(1) Let students get the knowledge actively by skimming, scanning and detailed rea ding.(2) Let the Ss design their own mind map.Part 5 Teaching Procedure （说教学过程）Now, let’s come to the teaching procedure. I have desig ned the following steps to tr ain their reading abilityStep 1 Warm-up and lead-inAsk students some questions about doing sports:Q1. Do you often do sports?Q2. What sports do you usually do?Q3. Can you list eight sports played in China?Purpose of my design(设计意图)(1) Lead in the topic and catch Ss’ attention about the topic.(2) It is a connecting link between the preceding and the following.Step 2 Pre-reading◇Task1 Let students look at some pictures and talk about the sports in the picture.Q1: W hat’s your favorite sport?Q2: Who’s your favorite sports star?Q3: Do you know how to play basketball?Purpose of my design(设计意图)(1) It is close to students’ life, so it can make them interested in the next studying.(2) Let Ss have the desire to read further◇Task2. Look at a picture and name the basketball equipment.Purpose of my design(设计意图)(1) To stimulate students’ interest in reading.(2) To provide the necessary background knowledge.(3) To lead in the topicStep 3 While-reading◇Task 1 Skimming1. Ask the Ss to look through the passage and find out the main ideas. Let the stud ents know maybe it’s a good idea to read the first sentences in each paragraph.2. After two minutes, students got the answer: The passage mainly talks about the hi story, invention and popularity of basketball.Purpose of my design(设计意图)Lead students know skimming is useful for them to find out the main idea of a pas sage.◇Task 2 ScanningLet the students read the first and second passage and answer the questions(1) When was the sports of basketball invented?(2) How popular is basketball?(3) Why were the Berlin Olympics important for basketball?Purpose of my design(设计意图)(1) Lead students to know the strategy of scanning, let them learn to scan the usefu l information they need.(2) Let students learn about something important about the history of basketball.◇Task3 Detailed reading1.

Blackboard design（说板书）Finally, let’s focus on the last aspect, the blackboard design. First, on the left, I w ill write down the title of this unit and put down the key words to make students realize t he importance of them and have a deeper memory. The PPT will hang out in the middle. The part next to PPT will be used for free writing and scores of each group will be wriPart 7 Teaching Reflections (说教学反思)In my opinion, it is successful. My reasons are as follows: Firstly, the teaching aims were quite clear. All the activities were focused on the theme “reading strategies” and w ere developed to reach the teaching goal----Enable the students to master the ways of exte nsive reading and reading in details. Secondly, task-based teaching method and making a mind map were adopted successfully. Thirdly, in this lesson I designed different activitiesto arouse the students’ interests of learning English. Such as: skimming, scanning, detailed reading and mind map. The students were eager to speak and use English in class. In ad dition, I think, the most shinning point of this lesson ismaking a mind map and introduci ng it to others. It is a new way for students to practice their spoken English. The student s became more interested and more active in thinking and using.No class is perfect. As a teacher, we should pay more attention to the students who are not good at English. We should encourage them more. Give them more chances to s peak and use English. I think, with more encouragement, they are sure to make greater pr ogress in the future.Above is my representation of this lesson. Thank you!。
