五、Teaching steps
Step1 Preparation
Now I have 4 gardens,they are for group 1,2,3,4.If you do well,you can get some flowers for your groups.(教師在黑板上畫(huà)個(gè)四個(gè)花園的形狀，分給四個(gè)小組，如果在課上他們表現(xiàn)的好就可以為他們組獲得花朵。既激發(fā)了同學(xué)們的竟?fàn)幰庾R(shí)，同時(shí)也為板書(shū)增色彩。)
1.Do as I do:walking, walking ,I’m walking./Running, running, I’m running./ Flying,flying,I’m flying./ Jumping ,jumping,I’m jumping./Swimming,swimming,I’m swimming./Climbing,climbing,I’m climbing./Cooking,cooking,I’m cooking dinner./Cleaning,cleaning,I’m cleaning the room…(通過(guò)課件出示這些動(dòng)詞，讓學(xué)生跟我做，這個(gè)熱身活動(dòng)既復(fù)習(xí)了現(xiàn)在進(jìn)行時(shí)，為新課做鋪墊，也為后面的擴(kuò)展活動(dòng)做準(zhǔn)備。)
2.Play a game(啞劇猜謎)
每組派兩名同學(xué)上臺(tái)做一個(gè)剛才熱身時(shí)的動(dòng)作，然后老師問(wèn)：What is …doing?He’s /She’s ….(由I’m doing …過(guò)渡到She’s /He’s doing…層層遞進(jìn).)
3. We are ready to go for the field trip now.Let’s sing a new song of “Field Trips”.
老師領(lǐng)唱歌曲。(以教學(xué)主題歌曲創(chuàng)設(shè)活動(dòng)情境，提示活動(dòng)主題，貼切自然。)(
Step2 Presentation
1.Last weekend our class had a field trip,too.We took many pictures about the field trip.Now let’s look at the pictures.
a.taking pictures
Look at this picture.What is …doing?引導(dǎo)學(xué)生回答：He’s doing an experiment.
教師出示“doing an experiment”的卡片，讓生跟讀，鼓勵(lì)學(xué)生邊說(shuō)邊做動(dòng)作。接著板書(shū)單詞，讓學(xué)生一起書(shū)空,并配上相應(yīng)的簡(jiǎn)筆畫(huà)。然后讓學(xué)生小組讀，個(gè)人讀。再拿出準(zhǔn)備好的試管，讓幾個(gè)學(xué)生做動(dòng)作，師先問(wèn)：What’s… doing?讓生回答：He’s doing an experiment.再讓生問(wèn)生回答。(練習(xí)形式由單詞到句子，做到詞不離句，層層遞進(jìn)。)
b.Look at this picture.What’s he doing?師示范說(shuō)：He’s watching insects.師在黑板上畫(huà)兩只螞蟻,并介紹“insects”.以同樣的方式練習(xí)“insects”,并讓一生拿著課前準(zhǔn)備的放大鏡上黑板做觀(guān)察螞蟻的動(dòng)做,來(lái)練習(xí)What’s he doing? He’s watching insects.
因?yàn)?ldquo;experiment和insects”的發(fā)音是個(gè)難點(diǎn)，所以在這個(gè)地方設(shè)置了一個(gè)冷暖游戲來(lái)突破這兩個(gè)難點(diǎn)。(讓一生背對(duì)全體學(xué)生，把詞卡藏在另一生的書(shū)底下，讓這生找，全體學(xué)生一起喊“experiment”，或“insects”當(dāng)這個(gè)學(xué)生離詞卡越近時(shí)，學(xué)生聲音越大，離它遠(yuǎn)時(shí)，聲音漸小，讓生跟據(jù)聲音的大小來(lái)找尋詞卡。)
c. 以上述同樣的方法操練catching butterflies,picking up leaves,taking pictures.
2.Listen to the tape.
聽(tīng)音正音部分我放了兩遍錄音，第一遍只讓學(xué)生邊聽(tīng)邊指，指讀對(duì)學(xué)生來(lái)說(shuō)是很有必要的，可有效改善學(xué)生的單詞認(rèn)讀能力差的情況。第二遍跟讀。
3.Read in groups.
單詞導(dǎo)呈和聽(tīng)音正音結(jié)束后的合作交流，我認(rèn)為就是學(xué)生咀嚼、消化的過(guò)程，是學(xué)生查漏補(bǔ)缺的過(guò)程，是為后面的Practice環(huán)節(jié)作好知識(shí)上的鋪墊的過(guò)程。學(xué)生在活動(dòng)前，教師一定要注意提出具體的學(xué)習(xí)要求，避免學(xué)生無(wú)目的的讀。我的合作要求是：Now read in groups. Pay attention to your pronunciation.You can help each other. Let’s see who reads best.
Step3 Practice
1.教師先用詞卡檢查學(xué)生的認(rèn)讀情況。
2.What’s missing? (說(shuō)和認(rèn)讀的訓(xùn)練)
3.Guessing game:what’s he doing?
讓學(xué)生到講臺(tái)上看老師出示的單詞做動(dòng)作，讓其他學(xué)生猜。師先問(wèn)：What’s he/she doing?生答：He’s/She’s…然后生問(wèn)生答。
4.Let’s chant:
Doing, doing,what’s he doing?
Watching,watching,he’s watching insects.
Taking,taking,he’s taking pictures.
Picking,picking,he’s picking up leaves.
Catching,catching,he’s catching butterflies.
Doing,doing,he’s doing an experiment.
(Chant既朗朗上口激發(fā)學(xué)生興趣，又富有實(shí)際意義，有利于學(xué)生理解與記憶。)
Step4 Production
1.課前準(zhǔn)備好四張大紙，每組一張，每張紙上都有個(gè)中心活動(dòng)如： Group1 is doing housework. Group2 is having a field trip. Group3 is having a sports meeting. Group4 is staying in the classroom. 每張紙上的動(dòng)詞都圍繞這個(gè)中心活動(dòng)，配上如李麗在照相的圖與相應(yīng)的動(dòng)詞，但是只給出動(dòng)詞，讓學(xué)生完成填空，并在小組內(nèi)練習(xí)句型。比如 take___ pictures讓學(xué)生試著加上ing,并讀出。
2.小組內(nèi)練習(xí)，利用句型What is Li li/he/she/ doing? He’s/She’s _____ing.充分討論。
3.讓各組學(xué)生匯報(bào)結(jié)果。
適當(dāng)?shù)募由锨楦惺芙逃篖ove nature,love life.
(通過(guò)便設(shè)情境，訓(xùn)練學(xué)生的口語(yǔ)交際能力及實(shí)際運(yùn)用語(yǔ)言的能力。)
Step5 Production
1. Do Activity Book.
2. 總結(jié)評(píng)價(jià)哪個(gè)花園里的花最多，即哪個(gè)組是今天的獲勝者。
3. Homework: ⑴.Listen to the tape and remember the 5 verb phrases. ⑵ Write a passage about your field trip.(將英語(yǔ)學(xué)習(xí)延伸到課外，達(dá)到學(xué)以致用的目的。)
