教师在习题改编中往往会遇到一些不错的试题,由于解题要求比学生所学知识水平要高,因而对如何改编会感到困惑.如果我们对这些习题给以一定的信息,让学生通过分析这些信息结合已学知识来求解,不仅巩固了知识又得到了能力的升华. Teachers often encounter some good questions in the adaptation of the exercises. Because the problem-solving requirements are higher than the level of knowledge students learn, they will be confused about how to adapt. If we give certain information to these exercises, let the students pass the analysis. This information is combined with learned knowledge to solve, not only consolidating knowledge but also sublimating the ability.
