命题是数学教师应具备的教学基本功之一,深入研究数学命题技巧,是充分发挥考试功能、教学改革成功不可缺少的一环.试题命制的教研活动对于教师的专业成长起到了不可忽视的作用.近期,笔者学习了改编试题的否定属性策略.借贵刊一角,谈谈否定属性策略在改编试题中的应用,以飨读者.早在1969年,美国学者Brown和Walter提出了问题的否定属性策略.他们将这种策略分为五个水平:水平0:选择出发点(如定理、具体材料、习题等);水平1:列出各个属性;
Proposition is one of the basic teaching skills that mathematics teachers should have. Studying mathematics proposition skills in depth is an indispensable part of giving full play to exam function and teaching reform success. Recently, I studied the negative attributes of adaptation questions strategy.From the corner of your magazine, to talk about the negation of attribute strategies in the adaptation of the test questions to readers.As early as 1969, the American scholar Brown and Walter raised the negative attributes of the problem Strategy They divide this strategy into five levels: Level 0: Choose a starting point (eg theorems, material, exercises, etc.) Level 1: List each attribute
