题记:数学学习就是一个不断修正错误、不断完善与积累经验的过程.作业讲评课的功效也在于此.1.背景.由于几何作业计算或推理的过程比较长,且步步有据,对于初学几何的学生来说经常会出现思路不清晰、依据易混乱等现象,有必要经常上习题讲评课.传统意义上教者往往就题论题,对学生作业中易错点加以强调,或不着边际地泛泛而谈,切不中要害,或不分轻重把解题过程加以呈现;学生被老师牵着鼻子走,
Inscription: Mathematical learning is a constantly correct mistakes, and constantly improve and accumulate experience in the process of homework is also commenting on the effectiveness of this lesson.1 background .Because the geometry of the process of computing or reasoning is relatively long, and step by step, for beginners Geometry students often appear not clear ideas, based on the phenomenon of chaos, it is often necessary to comment on the exercises .Traditionally traditionally tend to question the subject, the students miscalculation of homework to be emphasized, or not Generally speaking, not essential, or regardless of the severity of the problem solving process to be presented; the students were led by the nose,
