情境1:学生太差了!这道题我已经讲过很多遍了,但还有学生不会。(这是很多一线教师的抱怨)情境2:老师,你一讲我就会,但是我自己做题的时候,就找不到解题的思路。怎样才能知道一道题如何解?(这是不少学生的困惑)类似的情境经常发生在教学中,尤其是在几何学习中。究其原因,主要有两方面:一是很多学生缺少基本的解题活动经验,归纳应用能力比较薄弱;二是 Scenario 1: Students are so bad! I’ve talked about this question many times, but there are still other students who do not. (This is a lot of front-line teachers complain) Scenario 2: The teacher, I talk about you, but I do not find the problem-solving ideas. How to know how to solve a problem? (This is a lot of students confused) Similar situations often occur in teaching, especially in the geometry of learning. The reason, there are two main aspects: First, many students lack of experience in basic problem-solving activities, inductive application capacity is relatively weak; second is
