教学过程:

Step 1 Warm-up

(课前播放微课,回顾复习)。

本微课要求学生在家预习时观看,并完成进阶练习。微课内容主要是结合已知水果词汇,在创设的情景At the farm中学习了解可数名词单复数形式的变化规律,初步掌握What are these?They are.....的表达方式,为本课的学习打好基础。

T: What’s the weather like today? Can I go outside?

I want to go outside. I want to go there. Look. Where is it? Yes, it’s a farm..

Zhang Peng is at the farm. What can he see? What are these? They are...

Let’s chant:

Look at the apples. They are red.

Look at the bananas. They are yellow.

Look at the watermelons. They are green.

Look at the grapes. They are purple.

They are fresh! They are yummy!

They are good for you and me!

设计意图:因为本节课将要学习的内容涉及到可数名词的单复数形式,制作微课,明确预习的任务和目标,培养学生课前预习的习惯,也帮助学生回顾旧知,初步扫除下一步学习中的语言障碍,提高学习新知识的效率。

Step 2 Presentation

由观看微课直接导入课题,整合课本内容let’s learn 和Let’s talk ,在情境中结合自创的文本内容逐步学习掌握新知识。先是基于课前微课预习的情景,整体了解话题Vegetables,激发学生兴趣;然后是细读习得新词汇,并结合微课内容掌握它们的单复数形式,同时学习文本对话;最后化零为整,掌握对话。整个过程中贯穿健康教育的情感主线,尝试各种蔬菜,有益健康(Try some! They’re good.)

1. T: Look! Who are coming to the farm?

Now,they are at the farm. What else do they see?

设计意图:基于微课里的情境,设计新人物、新话题,并整合课本内容自编文本,这便于学生将所学语言材料进行综合、创造性地进行表达交流。这种练习方法,有接近生活的交际功能,而且能变单调、机械的句型操练为活泼、生动的交际性练习。

2.整体呈现,不呈现文本,要求看视频,听一听,回答问题,初步感受vegetables。

T: Listen and watch! What are they talking about? Then choose A,B or C?

S:...

T: Yes. C Vegetables. Say and write vegetable, vegetables.

设计意图:学习英语,“听”为先,听是基础。四年级的学生已经有了一定的英语词汇量的积累,所以在呈现新课文本时,教师以听导入,注意培养学生听的策略,也是为以后的英语长期发展打好基础。

3. 呈现文本再次听认读,结合文本细读习得新词汇和句型以及它们的单复数形式。

T: Listen and read! What vegetables are they talking about? Choose A,B,C,D,E,F.

S: A,B,C...

T: YES.! Let’s learn.

What’s this?It’s a tomato.(potato/carrot/green bean)

What are these? They’re tomatoes.(potatoes/carrots/green beans)

How do they like? They’re ......(red/ round/yum/good......)

Do you like...? Try some! They’re good.

Let’s chant :

设计意图:在听的基础上,可以进行说的练习了。这里还是基于课前预习微课的chant,逐步结合图片呈现文本,帮助学生理解对话的同时习得新词汇,在结合单词的音、形、义教学的同时,突出单复数形式和发音。然后配以歌谣,小对话形式达到语言输入的量。只有量的积累才有后面质(语言输出)的提高。同时进行健康教育,要尝试各种蔬菜,有益健康。

4.第三次整体呈现文本内容,要求学生跟读,注意问句的语调;结合图片和Guess Game 重点练习一般疑问句。

T:Look at the pictures. What are these? Can you guess?

Are these ...? Yes, they are. /No, they aren’t.

Let’s chant.

Are these ...? Yes, they are. Yes, they are.

Are these...? No, they aren’t. No, they aren’t.

设计意图:反复呈现对话文本内容,是在不断的复现,加强语言的输出,但每次的呈现又有不同要求,第一次主要是听,抓住关键词;第二次是听、认读,音、形、字在脑中有了对应;这次再听并跟读,并结合语音语调,又有了更深一层的要求。这样,对后面的语言内化才能起到促进。

Step 3 Practice

T: Now, who can try to read or act the dialogue?

1.再次整体呈现文本,学生自读对话练习并表演。

2. 分角色朗读对话,自查自纠。

3. 分角色表演对话。

设计意图:语言输出环节是检验教学效果的重要环节,在此教师也分了几个层次进行,可以针对不同水平的学生进行补缺补差;也可“以优带困”,让学优生做示范,让学困生跟上来;或者根据学生的表现调整接下来的教学环节。

Step 4 Add-activities

T: Design your dream farm and introduce it to your friends.You can change the words and say or make a new dialogue.

设计意图:此教学环节可以根据上一环节进行适当调整,可以是使用替换词编对话,也可以鼓励学生自己创造,甚至是添加内容。并适时告诉学生蔬菜的好处,教育学生不要挑食,多吃蔬菜有益健康。

Step 5 Homework:

1、Read or recite the dialogue on the book on page 38.(微信上发语音。)

2、Go to a farm . Next class, tell us what you see. Draw and say.(可选做)

设计意图:作业也是分层要求,虽然是自编了文本将课本教材进行了整合,但书本的基

本内容还是不能舍弃的,留着作业,也是反馈学生是否真的融会贯通了;其二的作业,也是根据现实情况而定的,因为在我们身边就有这样的农场供游人参观甚至是劳动,鼓励孩子身临其境,当所学的知识被使用,孩子才会有更大的兴趣。
