教学内容分析

本课时主要教学Sound time, checkout time & ticking time.发展学生的综合语言运用能力是基础教育阶段小学英语教学的根本目的。所以在这节知识巩固课的教学过程中，教师更要注重对学生语言知识、语言技能、情感态度、学习策略、文化意识的修炼。教师可以向学生渗透学习策略，单词记忆方法，怎样看图回答问题，怎样完成听力题等。对于语言技能的训练，现行的教材就给我们提供了很好的课文。对学生进行读写的训练，在此基础上让模仿范文，小组交流，培养学生的听说能力。最后鼓励学生将说的口头语言，变成写的书面语言，发展学生的写作能力。

教学过程

Step 1 Greeting & Revision

1. Greeting

2. Revision

T: Boys and girls, what's the topic of this unit?

S: Protect the Earth.

T: So, today, let's go on learning this unit.

(先让学生说说story time是从哪四个方面来保护地球的。)

S: Save water, save trees, save energy and don't use too much plastic.

(师根据学生的回答进行板书。)

T：They are more useful to our daily life. What can we do with them?

(PPT呈现课件)

S1: We use water to...

S2: We use wood to...

S2: We use coal to...

T: They are really important to us.

【设计意图】：复习旧知，巩固We use ...to...句型，为进一步学习做铺垫。

Step 2 Checkout time

1. T:课件呈现水枯竭，树木被伐光等地球被破坏的图片，师讲解。

T: Save the world, save our lives. So, do you want to be the “environmental small guard” to protect the Earth?

(课件呈现“环保小卫士”的图片)

  S：Yes.

  T: If you want to be the "environmental small guard ". You should pass two tests, understand?

2. Test 1 (课件出示Test1的过关条件)

T：（出示书76页的图片）Look at the pictures, can we do like that?

S: No.

T: What should they not do? Open your books and try to complete the sentences.

T: Have you finished? Let's check the answers, picture 1, what should he not do?

S1：He should not smoke in the restaurant.

(继续每一幅图，逐图与学生反馈答案)

T: read these sentences together.

T: What other behavior should we not do? Discuss in pairs.

(小组讨论，反馈，师板书并适当拓展)

T：Oh, You have passed Test 1, congratulations.

3. Test 2(课件出示Test2的过关条件)

T: Just now, we talked about the wrong behavior, right?

S: Yes.

T: So, if you're the “environmental small guard”, what should you do to protect the Earth?

（引导学生从保护资源，保护生态，减少污染这几个方面来讨论，每一大组选择一个方向，四人为一小组汇报）

T：Excellent! you can protect the Earth well. I think you can be the “environmental small guard” now.

【设计意图】：通过争当“环保小卫士”这一主线，为学生布置任务，激活学生的思维，激发学生的学习兴趣，贴近学生的生活实际。

4. Write a passage. (书77页 Think and write)                        

T: (课件呈现图片，让学生以“环保小卫士” 的身份给人类写封信。) Tell us: what should we do and what shouldn't we do.

T: If you need any help, just put up your hands, and I will help you with the spelling.

(学生完成之后，请个别学生到讲台前展示短文)

Step 3 Sound time

T: I think being an “environmental small guard” is a cool thing, do you think so?

S: Yes.

T: (课件出示图片) Look at this boy, what is cool to him? Let's listen.

       (课件出示句子并播放声音)

S1：go to school.

T：Yes. Why does he think so? Let's read together.

S: (read the sound time in different ways)

T: Look at the words, the "oo" is pronounced...?

S: /u:/

T: Good! Can you find more words like them？

T：And can you choose two of them to complete this sentence?

S：The house with a red roof, has a big swimming pool.

【设计意图】：通过读句子，体会单词发音，让学生自己找相同发音的单词，教师出示新的单词让学生拼读，内化语音规律，培养学生根据读音规则来拼读单词的能力并拓展了词汇量。

Step 4 Ticking time

T: Boys and girls, I think you did a good job just now. But did you do a good job for the whole unit? Let's check it out. Look! (PPT 显示4个目标) We have four targets in this unit. They are...

(学生自主评价，小组互评，最后老师检测，学生自己总结不足)

【设计意图】：逐条评价，相互评价，给了学生自我评价的主动权，有利于学生认识自我，有效调控自己的学习过程）

Step 5 Homework 家庭作业

Finish the exercise in Workbook.

结合研究主题进行评析

在传统的巩固复习教学中，由于教学内容有新的语言知识，教师往往在课堂上组织有意义的语言活动，发展学生的思维能力，而学生在认知事物时，需要经过一系列的思维活动，教师应根据学生的这一认知规律，在复习过程中设计相应的语言任务活动，使学生在活动中，发展思维能力，培养创新精神。除此之外，针对学生在课堂中出现的问题，教师也要将学生平时的共性问题加以提炼，并给予合理引导。只有这样；学生才能在追求知识的道路上走得更远。
