所谓学以致用,就是将所学到的理论知识运用到实际问题的解答中,实现抽象知识内容的具体化、深入化、灵活化.这种教学思路对于初中数学来讲非常适用.虽然初中阶段的知识内容不是整个数学学习过程中难度最大的,但是突然间变得抽象晦涩的内容摆在数学能力还不甚成熟的初中学生面前,仍然会使学生接受知识出现一些困难.因此,教师需要找到一个巧妙且到位的途径,让学生高效、 The so-called learning to apply, is to apply the theoretical knowledge learned to practical problems in the solution, to achieve the specific content of abstract knowledge, deepen, flexible.This teaching idea is very suitable for junior high school mathematics.Although the junior high school stage Knowledge content is not the most difficult in the whole process of math learning, but suddenly abrupt obscure contents still pose some difficulties for students to accept the knowledge, so teachers need to find out A clever and in place way for students to be efficient,
