一、问题的提出数学解题方法是解决数学问题的途径和策略,是数学思想的具体表现形式,初中数学常用的经典解题方法有配方法、反证法、面积法、待定系数法等等.在初中数学解题中,待定系数法被应用于求函数解析式、多项式因式分解等,在解题时使用比较频繁,所以“待定系数法”的教学也就格外重要.但是,很多教师偏执地认为“解题方法的教学就要让学生多做题,通 First, the problem put forward Mathematical problem solving method is to solve the math problems and strategies, is a concrete manifestation of mathematical thinking, junior middle school mathematics commonly used classical problem-solving method with matching method, inverse method, area method, to be determined coefficient method and so on. In junior middle school mathematics problem solving, the coefficient method to be determined is applied to find the function analytic, polynomial factorization and so on, which are used more frequently in problem solving, so the teaching of ”undetermined coefficient method“ is especially important.However, many teachers Paranoid think ”problem-solving method of teaching should let students do more problems
