背景分析：要想使小組合作學(xué)習(xí)能順利進(jìn)行并且充滿活力，采取適當(dāng)?shù)陌l(fā)展性評價方法與策略至關(guān)重要。評價是小組合作學(xué)習(xí)不可缺少的環(huán)節(jié)。
(一)教學(xué)目標(biāo)與要求
1、知識目標(biāo)：能夠聽、說、讀、寫動詞短語的ing形式。
2、能力目標(biāo)：學(xué)生能用句型表述他人正在進(jìn)行的動作。
3、情感目標(biāo)：使學(xué)生學(xué)會與他人進(jìn)行合作、交流。
(二)教學(xué)重點
重點掌握進(jìn)行時的表達(dá)方式和四個短語動詞的ing 形式。
(三)教學(xué)難點:重讀閉音節(jié)動詞現(xiàn)在分詞形式的變化。
(四)教學(xué)設(shè)備
cia, tape recorder, pictures
(五)教學(xué)步驟及說明
step 1: warm up
1.let’s chant：
what are you doing? what are you doing?
i am sweeping the floor. what are you doing?
i am reading a book. what are you doing?
i am drawing pictures. what are you doing?
i am washing clothes. what are you doing?
i am cleaning the
2. sing a song: what are you doing?
(設(shè)計意圖：唱歌是學(xué)生喜聞樂見的教學(xué)形式之一，通過說唱、唱歌等形式，引入課堂,能夠調(diào)動學(xué)生的學(xué)習(xí)興趣。)
step 2: revision
1.show students some photos, ask and answer:
-----what are you doing?
----i’m drawing pictures, reading a book, washing clothes, cleaning the dolls.
2. students write down the phrases on the blackboard and read.
(設(shè)計意圖：讓學(xué)生進(jìn)行兩兩合作，一個表演，一個運用句型復(fù)習(xí)四個已學(xué)過的動作，為下面的教學(xué)作好鋪墊，使學(xué)生能更好的掌握所學(xué)的句型。)
step 3. presentation
1. t: what do you usually do at the weekend?
s:i usually……(通過師生對話，直接引出詞組)
t: but i usually read books at home. i like reading books very much.
2. learn to say and spell “read books”.(學(xué)生跟讀詞組，并拼寫詞組)
3.show the photos, ask and answer: (從what are you doing句型引出what is he doing?句型)
-----what’s he doing?
-----he’s reading books.
4. learn to say the following three phrases and write down the phrases on the blackboard:(繼續(xù)引出其余三個詞組，并將詞組寫在黑板上，為學(xué)生以后的活動做準(zhǔn)備)
watch tv —— watching tv
sleep —— sleeping
run —— running
step4. drill and practice:
1.look at the photos, ask and answer:
what is he/she doing?
he’s/she’s……
2.look and guess:
there are three actions in the pictures, guess:
what’s he/she doing?
(設(shè)計意圖：通過模糊畫面，讓學(xué)生猜一猜他們在干什么，鞏固詞組，每幅圖片上三個動作，看誰記得最快，讓小組合作進(jìn)行說，看哪一組猜得多而準(zhǔn)確。學(xué)生對猜一猜的興趣較濃，再用小組競爭的形式讓學(xué)生進(jìn)行猜測，這既能調(diào)動學(xué)生的學(xué)習(xí)興趣，又能培養(yǎng)他們的團隊的合作精神。)
3.showing the pictures of page 48.practise the sentence patterns.(呈現(xiàn)書中d部分的圖片，操練句型)
4. do an action: students are divided into several groups. one acts teacher and says “everybody. do an action.”
