在教学中,对于同一道题,我们老师要善于引导学生从不同角度、不同侧面去分析研究,让学生思维的触角伸向不同的方向,不同的层次,这样他们就会得到不同的启示,从而引伸出多种不同的解法,提高解题技巧,即达到巧思妙解.1.妙在概念理解在关系复杂、条件隐含、数据缺少的情况下,抓住与解题相关的概念,进行推理、归纳、舍弃偏见,保留合理,达到妙解.例如,在一定温度下物质X的溶解度为M g,向(100+M)
In teaching, for the same problem, our teacher should be good at guiding students to analyze and study from different angles and sides, so that students’ tentacles reach different directions and different levels so that they will get different revelations. Introduce a variety of different solutions, improve the problem solving skills, that is, to achieve ingenuity and wonderful solutions. 1. Miao in the concept of understanding in a complex relationship, conditional implied, lack of data, seize the concepts related to solving problems, Reasoning, inductive, and abandoning prejudices, retaining reasonableness, achieving wonderful solutions. For example, the solubility of substance X at a certain temperature is Mg, to (100+M)
