命制一套规范,科学的数学试题,是一项艰苦细致的工作,稍有不慎就会出庇漏.本文试剖析近年中考数学试题中的一些失误现象,以期引起命题人员的注意,做到防患于未然.1.叙述不严密由于题目叙述含糊,干扰考生对题意的理解,使得解答与命题人员的想法相违.例1 命题“矩形是平行四边形”的逆命题是____.剖析:这类试题是中考的常考题型,试题本意是要求考生写出命题“矩形是平行四边形”的逆命题,但考生理解成是一个数学判断而填上
It is a hard and meticulous job to order a set of standardized and scientific mathematics test questions. If you accidentally leave it out, you will try to analyze some of the mistakes in the mathematics test questions in recent years in order to attract the attention of the propositioners. To prevent accidents before it occurs. 1. The narrative is not exact Because the title ambiguity is ambiguous, it interferes with the examinee’s understanding of the meaning of the question, making the answer contrary to the propositional person’s idea. Example 1 The proposition that the “rectangle is a parallelogram” proposition is __. Anatomy: This type of exam is a regular exam type in the exam. The exam is intended to require the examinee to write the inverse proposition of the proposition “rectangular is a parallelogram”, but the examinee understands it as a mathematical judgment and fills in
