纵观中学数学教学的现状,应该看到,大多数数学课基本上还是在应试教育的惯性下运作.特别是数学复习课,仍然陷于无边的题海.如何走出题海,改变单纯靠习题堆砌的大运动量机械训练的模式?我们觉得,充分发掘教材,对教材中的一些典型习题进行变换、串联、延伸、迁移,以少胜多,提高训练质量,真正做到遵循大纲、紧扣教材,是最根本的途径.现举一例介绍我们的一些尝试. Looking at the status quo of middle school mathematics teaching, it should be noted that most mathematics classes are still basically run under the inertia of exam-oriented education. In particular, mathematics review class is still stuck in endless questions. How to get out of the sea and change simply relying on practice stacking In terms of the mode of large-volume exercise training, we feel that we should fully explore teaching materials, transform, cascade, extend, and relocate some of the typical exercises in the textbooks to improve the quality of training and truly follow the outline and the teaching materials. It is the most fundamental way. Here is an example of some of our attempts.
