1 教材分析1.1 教学内容的地位和作用本节内容在小学与中学教材之间起着承上启下的作用.小学对几何知识的学习,基本停留在感性认识阶段(主要学习实验几何),还没有达到理性的认识,因而在中学有必要在小学学习的基础上,重新系统地学习几何.所以本节课首先提出几何所研究的对象和内容,让学生对几何有初步的了解,再通过几何在生活实践
1 Analysis of Teaching Materials 1.1 Status and Role of Teaching Content This section serves as a link between the elementary and middle school textbooks. Primary school’s learning of geometric knowledge basically stays at the stage of perceptual knowledge (mainly learning experimental geometry) and has not yet reached a rational level. Therefore, in the middle school, it is necessary to study geometry systematically on the basis of learning in primary schools. Therefore, in this lesson, we first propose the objects and contents of geometry study, so that students can have a preliminary understanding of geometry, and then use geometry to practice life.
