解题教学是数学教学中的重要组成部分,正如波利亚所说:“中学数学教学的首要任务就是加强解题训练.”通过解题教学,运用重要的数学思想不仅可以强化学生对数学基础知识的理解和基本技能的掌握,还可以发展学生的思维能力,提高学生的数学素质.如“分类讨论”思想可以很好的培养学生思维的灵活性.通过合理分类,可以将问题化整为零,逐一突破.由于分类讨论要做到不重不漏,对学生思维能力提出较高的要求,
Problem-solving teaching is an important part of mathematics teaching, as Polia said: “The primary task of mathematics teaching in middle schools is to strengthen problem-solving training.” By solving problems and applying important mathematical ideas, students can not only strengthen students’ The understanding of basic knowledge of mathematics and the mastery of basic skills, but also can develop students ’thinking ability and improve the students’ mathematical qualities, such as “classified discussion ” thinking can well cultivate the flexibility of student thinking through reasonable classification, you can Problems into zero, one by one breakthrough.Because classifications should be done without serious omission on the thinking ability of students put forward higher requirements,
