適當(dāng)使用多媒體
多媒體可以把文字，圖像，聲音，動(dòng)畫集于一起，增加課堂教學(xué)容量，活躍課堂氣氛，提高課堂效率。講高三第14單元時(shí)，老師用多媒體教學(xué)。老師先把一副圖展現(xiàn)給學(xué)生，這副圖的內(nèi)容是一只蜜蜂趴在一朵花上。然后師生對(duì)話。
T: What’s this?
S: It’s a bee.
T: Would you like to say sth about bees?
S: They live in groups.
S: They collect honey.
S: They are hard-working workers. We should learn from them.
T: How do they communicate?
S: They communicate by dancing.
T: What kind of information do they convey?
S: They convey the information of food.
然后，老師再搖擺舞和圓圈舞的圖展現(xiàn)給學(xué)生。
T: What’s a circle dance ?
S: First it makes a circle to the right, then to the left.
T: What’s a wagging dance?
S: The dancer ran in a straight line, wagging from side to side. Then it turned in a semicircle, ran straight again, then turned in another semicircle to the opposite again.
T: What’s kind of news do they communicate each?
S: The circle dance sent the massage that the food was near the hives. The wagging dance sent the massage that the food was far away.
最后，老師讓學(xué)生總結(jié)這一課的內(nèi)容，寫一篇蜜蜂的文章。50字左右。
The honey-bees
The honey-bees live in large groups. They communicate with each other by dancing, not by sounds. There are two kinds of dancing, one is the circle dance, the other is wagging dance. The circle dance communicates that the food is near, while the wagging dance sends that the food is far away.
通過多媒體，這節(jié)課很成功，導(dǎo)入自然，各個(gè)環(huán)節(jié)緊緊相扣，課堂氣氛活躍，體現(xiàn)了師生互動(dòng)，生生互動(dòng)，知識(shí)上掛下聯(lián)
