这里的“题”指一切考纲范围内的数学问题,包括知识点,基本原理和各类题型.“解”指根据题目条件,通过不同角度的理解产生不同的解题方法.从不同角度思考问题,认识问题,能够提高学生的认知水平,掌握知识的本质含义,激发学习兴趣,拓展思路,激发他们的变通思维,发散思维.其实,在教材中很多知识点,公式的推导都强调一题多解.勾股定理,基本不等式,等差数列的通项公式……不胜枚举.可以说,一题多解就是
Here “question ” refers to all the math problems within the scope of the syllabus, including knowledge points, basic principles and various types of questions. “Solution ” refers to the conditions under the topic, through different perspectives to produce different solutions to problems. Thinking from different angles, understanding problems, can improve students’ cognitive level, grasp the essential meaning of knowledge, stimulate interest in learning, expand ideas, stimulate their workable thinking, divergent thinking.In fact, in the textbook a lot of knowledge points, formula The derivation emphasizes one problem and many solutions. The Pythagorean theorem, the basic inequality, the arithmetic formula for the arithmetic progression, etc ... can be said to be numerous.
