近几年来 ,“铺垫型”研究性试题开始崭露头角 ,逐渐成为全国各地中考数学命题的新亮点 .这种题型 ,乍看似有超越初中数学教学大纲、超过学生可接受的研究程度之嫌 ,但由于这些题目有“铺垫” ,考生可从简单情形入手 ,向特殊情况转化 ,在归纳中探索结论 ,让考生经历观察、分析 In recent years, the “bedding type” research questions have begun to emerge, gradually becoming new highlights of the national mathematics propositions across the country. This type of question seems to be beyond the junior middle school mathematics syllabus, beyond the students acceptable level of research, However, because these topics are “foreshadowing”, candidates can start with simple situations, transform into special situations, explore conclusions in induction, and allow candidates to experience observations and analysis.
