数学试题的编拟是教师创造性教学活动的基本功之一.笔者认为首先应遵循科学性原则,所谓科学性原则指有关的数学概念必须是被准确定义的,有关的记号必须是被清晰标明的,条件必须是充分的、不矛盾的,条件必须是独立的、最少的,叙述必须是清楚的,要求必须是可行的.罗增儒教授认为,如果我们把每一道数学题都看作一定数学系统的子系统,那么题目的条件与所在系统的公理组成的体系应该具有:充分性——足以推导出题目的结论;独立性——每一个条件都不
The preparation of mathematical questions is one of the basic skills of teachers in creative teaching activities.I think the scientific principle should be followed firstly.The so-called scientific principle means that the relevant mathematical concepts must be accurately defined, the relevant symbols must be clearly marked, Conditions must be sufficient, not contradictory, the conditions must be independent, at least, the narrative must be clear, the request must be feasible .Ruo Zengru think, if we think of every mathematical problem as a mathematical system System, then the conditions of the title and system where the system of justice should have: Sufficient - enough to deduce the conclusion of the title; Independence - each condition is not
