苏教牛津版英语三上《On and off》教学实录
step 1 : warming-ups:
1. sing a song: （上课前两分钟）
（设计意图：三年级时刻重视字母教学，用字母歌复习，同时渲染英语课气氛。）
2. greetings:
t: look, this is a nice room. what colour is it?
s: it鈥檚 yellow.
t: some 鈥Γ╣rapes）。
hello, i am miss zeng. i like yellow. i like mangoes. hi, how are you?
s: i鈥檓 fine. thank you. and you?
t: i鈥檓 fine,too. let鈥檚 go to the zoo.
s: all right.
ss practise.
（设计意图：对于小学生而言，英语知识需要反复的巩固，这部分知识涵盖了几个单元的内容，从单词到句子都有体现。同时鈥渋 like鈥澋牟倭芬晨梢砸鲂碌ゴ示湫偷慕淌凇＃�
t: i like yellow. i like watching tv.
step 2 presentation and practice:
1. tv
learn
t: look, this is a tv.
e b c d g p t v
that鈥檚 a tv, too.
let鈥檚 watch tv.
xx,turn on the tv, please.
2. turn on the tv, please.
learn < turn on the tv, please.>
ss practise.（ one by one , one or two , a group ）
（设计意图：这个句型理解不难，但是读音不容易，所以在开始呈现时就应打下坚实的基础，机械操练到位，为下面有意义的生成准备。）
t: who can say: 鈥� miss zeng, turn on the tv please.鈥�
ss say and t turns on the tv.
t: time for class. xx, turn off the tv, please.
s: all right.
learn < turn off the tv, please.>
t: bird says/ elephant says/ monkey says/boy says/ girl says鈥︹��
（设计意图：通过让学生模仿各种动物的声音操练句型，达到巩固的效果。）
ss practise in pairs. （在黑板上各组的鈥湻孔逾�澙锘弦惶╰v表示奖励，第二次奖励时画上一台light。）
3. light
t: is this a tv?
s: no, it鈥檚 a light. （ helping）
learn 鈥� light鈥� （ hi ,nice）
（设计意图：通过奖励引出light一词，学生印象较深刻，过渡也自然，顺利进入下一环节的教授。）
t: look at some lights.（多媒体呈现四幅灯的图片）
this is a light.
that鈥檚 a light, too.
（设计意图：单词的操练不应仅仅是重复的读，我通过图片让学生针对不同的对象巩固同一单词，也起到了操练的效果。）
t:xx, turn on/off the light, please.
s: all right.
read after the teacher. （ turn on/off the light. ）
ss practise.（此处一生在大家齐声鈥溍钼�澫驴亟淌依锏牡啤＃�
（设计意图：对话操练除了小组对话还可以是个体和全体之间的对话，此处我就采用了这种方法，个体边回答边做动作，也使操练具体化。）
say a chant: tv, tv, turn on the tv.
light, light, turn off the light.
4. walkman
let鈥檚 play a game. guess, what鈥檚 in the bag? touch it,please.
s: a walkman.

s: turn off the walkman,please.
t: all right.
t make a dialogue with a student.
ss practise in pairs.（画一个walkman作为奖励。）

light, light, turn off the light.
walkman, walkman, turn on the walkman.
5. tap
t: let鈥檚 play a magic game. first., look at the picture. what can you see?
s: i can see a tv, a light.
t: i can see a tv, a light and a room. close your eyes.
open your eyes. what can you see now? （屏幕上的tap藏在一个角落里）
s: i can see a tap.
learn
（设计意图：用变魔术的方式引出tap，在学生逐渐涣散注意力时及时呈现新单词，让好动的小学生的注意力又一次集中。）
t: （look at the hands.） too dirty. （作洗手状） xx，turn on the tap ,please.
s: all right.
t: （作洒水状） turn off the tap,please.
s: all right.
learn : turn on/off the tap.（ 小组之间进行命令问答，操练句型。）
ss practise in pairs.
step 3 : consolidation
1. play a word game.（课件上呈现半遮的图片）
t: what鈥檚 this?
s: it鈥檚 a 鈥Α�
（设计意图：让学生在思考中巩固单词，代替了重复的朗读。同时在单词中，我加入了几个以前的单词鈥溍曰筲�潱谜庖换疃挥刑粽叫浴＃�
2. show the room picture., using 鈥� here鈥檚 a 鈥Αｂ�� to review the words.
t: guess, here鈥檚 a 鈥Α�
（设计意图：让学生在整体的房间中安排单词，将提高他们对单词的认识。）
3. say the chant again.
step 4 learn the dialogue
1. show the two pictures.
t: look ,this is鈥Α＃ń樯苋宋铮鳎�
2. listen and repeat.
3. read together.
4. act it out.
