在学生掌握论证方法之后,为使学生掌握分析方法,即从命题的结论出发,找到使结论成立的条件,逐步进行逆推,一直逆推到与命题的题设或图形的直观性质相符合为止。可采用分析图表的方法,把分析的过程按层次清楚的反映在图表上。它不但可以培养学生严密的逻辑推理能力,而且还能提高分析能力,更为今后使用推导符号打下基础。先通过简单的例题讲透方法,然后逐步展开。讲解时要善于把分析中的失败和曲 After the student masters the method of reasoning, in order to enable the student to master the analysis method, that is, starting from the conclusion of the proposition, find the conditions for the conclusion to be established, and gradually carry out the inverse process, and always push it backward until it conforms to the intuitive nature of the title or figure of the proposition. . You can use the method of analyzing charts, and the analysis process is clearly reflected on the charts in layers. It can not only cultivate students’ strict ability of logical reasoning, but also improve their analytical ability and lay the foundation for using derivation symbols in the future. First through a simple example to explain methods, and then gradually. When explaining, be good at the analysis of failures and songs
