在高三数学复习中,教师会针对学生在知识上、方法上的错误进行一番讲解,学生会经过一番纠错,然而,当同类题目再次出现时,不少学生仍会出错,教师觉得很困惑:“课堂上讲了,学生也练了,为什么还会出错?”其实,问题往往就出在“讲”与“练”上.新课程要求实施“自主、合作、探究”的学习方式和“启发、讨论、参与”的教学方式,然而,在实际教学时落实的并不是很好,高三数学教学仍普遍存在“教师满堂灌、学生大量练”的固定模式,教师想通过多讲、多 In the third year of maths review, the teacher will give some explanations on the students’ knowledge and methodological errors, and the students will go through some mistakes. However, when similar problems appear again, many students still make mistakes and the teachers find it very confusing. In fact, the problems often lie in “stresses” and “training.” The new curriculum requires the implementation of “autonomy, cooperation, Exploring ”and“ inspiring, discussing and participating in ”teaching methods. However, it is not well implemented in the actual teaching. The teaching of mathematics in the third grade is still commonplace.“ Teachers are full of classes and students practice intensively. ” Fixed mode, teachers want to talk more, more
