在原来的上课中,是教给孩子在三个变量当中,如何控制两个变量,然后只改变一个变量,来考察是哪个因素改变摆的快慢,并且设计好记录表,让他们填上,最后得出结论,摆的快慢和摆的长短有关系,和摆的重量没有关系,和摆的角度关系不大。那个时候我想教孩子科学研究的方法,一套科学实验操作,一步一步按要求讲得很细,指导得很细。 今天这节课,什么都没讲,什么都没说,“你去干去吧！”于是孩子们不知道应该从哪做起。因为我们以前对孩子们培养的基础还不够,他们不知道应该怎么样自己独立去完成,不知道怎样做记录。因此,五花八门的记录都上来了。好不好呢?我觉得是好事,起码我们了解了我
In the original class, is to teach children in three variables, how to control the two variables, and then change only one variable to examine what factors change the speed of the pendulum, and design a good record sheet so that they fill in, and finally Concluded that the speed of the pendulum and the length of the relationship has nothing to do with the weight of the pendulum has little to do with the angle of the pendulum. At that time I want to teach children scientific research methods, a set of scientific experiment operation, step by step to speak very carefully, the guidance is very fine. Today's class, did not say anything, did not say anything, “you go to go!” So children do not know where to start. Because we did not have enough foundation for children in the past, they did not know how to do it independently and did not know how to do it. Therefore, all kinds of records are up. OK? I think it is a good thing, at least we know me
