传统初中数学教学中的题海战术已经被逐渐淘汰,取而代之的是素质教育下的有效教学,成功避免了学生出现“高分低能”状况.习题教学是巩固理论知识,培养学生对知识运用能力的有效方式,能够对数学学习起到导向作用.目前,习题教学分为三个步骤,即巩固复习、知识应用以及拓展练习.因此,教师应注重对习题的讲解,以此来提升学生自主解题能力.要想避免学生在解题时出现错误,首先应该了解学生自主解题过程中容易出现的错因,以错因为主线展开解题指导,提升解题教学的有效性. The traditional tactics in junior high school mathematics teaching have been gradually eliminated, and replaced by the effective teaching under the quality education, the success of avoiding “high score low energy ” situation of students.Exercise teaching is to consolidate the theoretical knowledge and train students to apply knowledge Ability and effective way, can play a guiding role in mathematics learning.At present, the problem teaching is divided into three steps, namely, to consolidate the review, the application of knowledge and to expand the practice.Therefore, teachers should pay attention to explain the exercises in order to enhance student autonomy In order to avoid students’ mistakes in solving problems, we should first understand the mistakes that students are prone to occur during the course of self-solve problems, and correct the mistakes because the main line solves the problems and guides them to improve the effectiveness of problem-solving teaching.
