《数学课程标准》(以下简称“新课标”)提出,数学教学中要运用数学的思维方式进行思考,增强学生发现问题和提出问题的能力、分析问题和解决问题的能力(以下简称“四能”).在实际教学中,教师如何引导学生从生活到数学,从已有图形的零散知识到用数学的眼光去认识几何?这是一个值得我们认真思考的问题.下面以苏科版七年级上册《丰富的图形世界》为例,谈一谈如何在教学中通过学生动手操作和主动参与数学实验, “Mathematics Curriculum Standards” (hereinafter referred to as “new curriculum standards”) proposes that mathematics teaching should use mathematical thinking to think and strengthen students’ ability to find problems and raise questions, analyze problems, and solve problems (hereinafter referred to as “ability”). “Four can”). In practical teaching, how can teachers guide students from life to mathematics, from the scattered knowledge of existing figures to the use of mathematics to understand geometry? This is a question worthy of our serious consideration. In the seventh edition of Suco’s edition of “The Rich Graphical World” as an example, talk about how to use student hands-on operations and actively participate in mathematics experiments in teaching.
