数学教学要重视结论的推导过程,因为在这个过程中往往具体体现了数学的基本方法和重要思路。去年秋季,常州市二中、三中、九中、二十一中在初一年级结合“加强知识发生过程实验教材”进行了教改试验,实验班从《有理数》一章的教学开始就逐步渗透了一些数学的思想方法,取得了初步的效果。下面介绍的这节课就是在这种渗透性训练的基础上教学的,文中T表示教师,S表示学生。
Mathematical teaching should pay attention to the derivation of conclusions, because in this process often embodies the basic mathematical methods and important ideas. In the autumn of last year, Changzhou No.2 Middle School, No.3 Middle School, No.9 Middle School and No.21 Middle School conducted the experiment of teaching reform in the first grade with the experimental materials of “strengthening knowledge process”. The experimental class gradually infiltrated from the teaching of “Rational Number” chapter A number of mathematical thinking and achieved initial results. The following lesson is taught on the basis of this permeability training, where T is the teacher and S is the student.
