1前言命制试题对初中数学教师而言,一方面需要教师深入理解《义务教育数学课程标准(2011年版)》规定的课程内容及其所倡导的考试评价理念;另一方面教师要熟悉数学试题命制的原则、程序、方法、技巧、策略等.为了在教学中快速高效地命制出一些内涵丰富、形式新颖、别具一格的试题,笔者在这方面做了一些有益的尝试:注重提炼几何模型,以几何模型作为命制几何试题的源头与活水,不但可以快速高效地命制出一些优秀的几何
1 Foreword The test of life system for junior high school mathematics teachers, on the one hand, teachers need to thoroughly understand the “compulsory education mathematics curriculum standards (2011 edition)” stipulated in the course content and the concept of the examination and evaluation advocated; the other hand, teachers should be familiar with mathematics test The principles, procedures, methods, techniques, strategies, etc. of life system. In order to quickly and efficiently produce some test questions with rich connotations, novel forms, and unique styles in teaching, the author has made some useful attempts in this regard: focusing on refining geometric models. The use of geometric models as the source of live geometry questions and living water not only allows you to quickly and efficiently produce some outstanding geometry
