一次科学观摩活动中,老师在指导孩子们做蜡烛燃烧的实验:点燃两支同样大小的蜡烛放在盘子里,盖上两个大小不一样的玻璃杯,让幼儿发现空气与燃烧的关系。大多数幼儿很快得出了结论:小杯子盖的蜡烛先熄灭,因为小杯子里的空气少。只有一名幼儿得出了相反的结论:大杯子盖的蜡烛先熄灭。老师说:你再去试试吧。他也发现了只有自己的答案与别人的不一样,没吭声,他又去试了几次,但仍然是这个结果。这一次,他理直气壮了,大声嚷嚷着告诉大家“是大杯子盖的蜡烛先熄灭”。这一嚷立刻引起了其他幼儿的反对,课堂上一片争论声。在旁边一直观察他的张慧和教授开始参与进来,“你刚才做得很好,我相信你是对的,可为什么会与别人的结果不一样呢?再试试好吗?”在张教授的鼓励下,他又去点燃了两支蜡烛,张教授帮他盖 During a scientific activity, the teacher instructed children to experiment with burning candles: light two candles of the same size on a plate and cover with two glasses of different sizes so that young children could find the relationship between air and burning. Most young children quickly come to the conclusion that the small cup covered with a candle goes out first because there is less air in the small cup. Only one young child came to the opposite conclusion: the candle in the big cup goes out first. The teacher said: You go try it. He also found that only his own answer is not the same as others, did not say anything, he went to try several times, but it is still the result. This time, he confidently, shouting loudly to tell everyone “is the big cup of the candle to extinguish.” This clamor immediately aroused the opposition of other children, a controversy in the classroom. Professor Zhang Huihe, who has been observing him all the time, started to participate. “You just did a good job, I believe you are right, but why is it different from the others? Try again?” Professor Zhang Encouraged, he went to light two candles, Professor Zhang helped him cover
