美国著名数学教育家波利亚曾说过:“教师讲什么不重要,学生怎么想比这重要一千倍。”由此可见,读懂学生非常重要。它既是教师设计教学的前提,也是教师上好课的必要条件。因此,我们现在的课堂教学应该以“读懂学生”为立足点和出发点,处处体现 Polly, a famous American mathematics educator, once said: “What teachers say is unimportant and how students think it is a thousand times more important than this.” Thus, it is very important to understand students. It is not only a prerequisite for teachers to design teaching, but also a necessary condition for teachers to take good lessons. Therefore, our current classroom teaching should be based on “reading students ” as the starting point and starting point, reflected everywhere
