有数学的学习就有解题。在解题实践中,所有人都有过解错题的体验,思路不清晰、叙述不严谨、考虑不周密、概念理解不清、知识结构残缺等,这些错误往往集中表现在需独立完成的数学作业或考试中。面对形形色色的错解,不能简单地将错误归结于粗心大意,而应该以严肃认真的态度看待错解,认真分析,找出错误的深层次原因,进而获得有益的启示,不断总结、完善自己,真正实现“错中得益”。本文将笔者在“常用逻辑用语及推理证明、算法、概率、统计”单元的作业及试卷批阅过程中,发现的学生错解整理出来,以便对同学的学习有所启示。 There are problems with math learning. In the practice of solving problems, all people have the experience of solving the problem, the thinking is not clear, the narrative is not rigorous, the consideration is not clear, the concept is not clear, the knowledge structure is incomplete, etc., and these mistakes often focus on the mathematics Homework or exam. In the face of misunderstandings of all kinds, we can not simply attribute the mistake to carelessness. Instead, we should treat misunderstandings with seriousness and seriousness, analyze them carefully, and find out the deep-seated causes of mistakes so as to obtain useful enlightenment and keep concluding and improving ourselves , Really “wrong benefit ”. In this paper, the author in the “common logic and reasoning, algorithm, probability, statistics,” unit operations and papers review process, the students find the wrong way sorted out in order to enlighten the students learning.
