数学实践告诉我们,作为一个教师、掌握一些常用的编题方法是非常必要的。这有利于我们联系教学实际、学生实际,根据教学中不同阶段的要求编造习题进行教学,这对提高教学质量无疑是十分重要的。 本文探讨的递推编题法,是由命题结论(或中间结果)逆推命题条件的一种编题方法。下面举例谈谈递推法编题的过程。
The practice of mathematics tells us that as a teacher, it is very necessary to master some common methods of editing. This is conducive to our contact with the actual teaching, the reality of the students, according to the requirements of the different phases of teaching to create exercises for teaching, which is undoubtedly important to improve the quality of teaching. The recursive editing method discussed in this paper is a method of editing the propositional condition by inverting the propositional result (or intermediate result). The following is an example of the process of recursive editing.
