对于数学学习中的预习学生似乎不习惯。而大多数数学教师也放不开让学生自己去预习,总认为学生自已看不懂,怕浪费了时间。总之老师和学生都没有养成这种习惯,因此传统式的教学中学生总是等待老师来 It does not seem to be accustomed to preparing students for mathematics learning. The majority of mathematics teachers can’t let students prepare for themselves. They always think that students can’t read it and fear that they will waste time. In short, teachers and students did not develop such habits. Therefore, in traditional teaching, students always wait for teachers.
