在新评价理念的指导下,我们对数学命题作了一些有益的研究和探索。本文试以三组试题为例,谈一些具体的做法。一、创设生活情境,凸现现实性命题1:选择正确的答案或序号填入括号内。一个数增加10%后再减少10%,这个数和原数比是()A.增加了B.减少了C.不变这是目前试题中一道常见的,
Under the guidance of the new evaluation concept, we made some useful research and exploration on mathematical propositions. This article tries to three groups of questions, for example, talk about some specific practices. First, the creation of life situations, highlights the reality Proposition 1: Select the correct answer or serial number in brackets. A number increased by 10% and then decreased by 10%, the number and the original number is () A. Increased B. Reduced C. This is a common problem in the current test,
