如何引导学生思考并解决问题是当下数学课堂改革面临的严峻问题。本文以一道中考试题的解法探究,谈一点认识。一、精选习题,连点成线数学习题课是为了巩固学生所学知识而设,笔者认为每堂习题课都应像新授课一样,要有明确的教学目标。例如对于新人教版九年级下第二十六章:二次函数性质教学过后的习题课,应注重选择“数形结合”的试题,让学生体会二次函数的“式”与
How to guide students to think and solve the problem is the current math classroom reform is facing a serious problem. In this paper, a middle school exam questions to explore, talk about a little understanding. First, the selection of exercises, even points into line mathematics exercises is to consolidate the students learned knowledge and set, I think each exercise class should be the same as the new lectures, there must be a clear teaching goals. For example, the New PEP version ninth grade under the twenty-sixth chapter: the nature of the quadratic function after the exercise class, should pay attention to the choice of “combination of” with the “questions” to enable students to understand the quadratic function versus
