【摘要】 在不同版本的数学教材中,每一章内容开始之前都有章引言、章头图的内容,近年来,章引言、章头图的作用越来越得到广大学者的重视,与之相应的,一种新型课程"章起始课"出现了,对章起始课教学实践相关理论的研究也逐渐成为当前教育教学理论研究的热点。本研究以北师大版初中数学《二次函数》这一章的教学设计为例,提出了初中数学章起始课的教学策略,为初中数学章起始课的教学提供了一定的借鉴。更多还原

【Abstract】 In different versions of mathematics textbooks, there are introductions and diagrams before the beginning of each chapter, and in recent years, the role of chapter introductions and diagrams has received more and more attention from scholars. Accordingly, a new type of course “Chapter Starting Lessons” has emerged, and the research on the theories related to the teaching practice of chapter starting lessons has gradually become a hot spot of the current theoretical research on education and teaching. This study takes the teaching design of the chapter of “Quadratic Functions” in the Junior High School Mathematics of Beijing Normal University edition as an example, presents teaching strategies and provides some insight into the chapter starting lesson of junior high school mathematics.更多还原
