培养学生的创新思维和学习能力是数学教学的重要目的。初中几何教学能有效锻炼学生的思维,而四边形又是初中几何的重要内容,纵观几年的中考题,很多与四边形有关的题来源于课本原型,因此对四边形课本例题教学的探讨显得尤为重要。本文就笔者在四边形课本例题教学实践中积累的一些素材和案例谈几点粗浅的认识。
Cultivating students’ innovative thinking and learning ability is an important goal of mathematics teaching. Geometry teaching junior high school can effectively exercise students’ thinking, and the quadrilateral geometry is an important part of junior high school. Throughout several years of the senior high school entrance examination questions, many of the questions related to the quadrilateral derived from the textbook prototype, so the quadrilateral textbook sample teaching is particularly important . This article on the author in the teaching of quadrilateral textbook examples accumulated some of the material and case talk about a few superficial understanding.
