数学教学,离不开解题.解题教学是数学教学的一个重要组成部分.通过对解题教学的调查、分析与思考,可以较完整地了解学生在解题过程中数学思维活动的真实状况,从而有助于我们从不同角度来审视、评价教材,改进教师课堂教学的方式与方法,进而提升数学教师的教育教学水平.前不久,笔者听了一堂习题讲评课,对一道填空题的讲评有些疑惑,于是在课后有意识地进行了抽样 Mathematics teaching can not be solved without solving problems. Problem-solving teaching is an important part of mathematics teaching. Through the investigation, analysis and thinking of problem-solving teaching, students can fully understand the true state of mathematics thinking activities in solving problems. This helps us to examine and evaluate teaching materials from different perspectives, and to improve teachers’ classroom teaching methods and methods, and thus improve the level of education and teaching of mathematics teachers. Not long ago, the author listened to an exercise commentary class and commented on a blank-filling question. With some doubts, I consciously sampled after class
