【案例】认读钟面上的时刻:()时()分这是一道北师大版第二册有关时间教学的习题。当时教学很顺利,学生掌握得也还不错。但在课后的作业练习中,我发现很多学生的答案都是7时55分。低年级的学生思维简单,可能是还不怎么理解,或是不怎么熟悉,毕竟时间比较抽象,出现这样的错误也不足为奇。于是,在课堂上我将此类题目分析研究了一回,方法是老套的,但探究是深入的,我想下次总不会有人错了吧。

[Case] ​​read the time on the clock face: () when () This is a second edition of the Beijing Normal University book about time teaching exercises. At that time, teaching was smooth and students were good at it. However, after homework exercises, I found that many students answered the answer at 7:55. Students in lower grades have a simple thinking which may not be well understood or not yet familiar. After all, the time is rather abstract and it is not surprising that such errors should arise. So, in class, I analyzed the topic once and for all. The method is old-fashioned, but the inquiry is in-depth. I think next time nobody will be wrong.
