几何是初中数学的重要组成部分,影响着学生数学思维和数学能力的发展。新版《数学课程标准》明确指出要让学生综合性地掌握几何知识,并通过几何学习获得综合素养的提升和空间想象能力的发展。几何变换思想不仅是学生应该掌握的一种学习方法,也是新课改要求的一项重要内容,它蕴含于几何知识的学习中,是课堂教学的隐性目标,影响着学生对几何知识的理解。一、初中几何教学的现状分析几何是数学的重要组成部分,在初二学段开始设置课
Geometry is an important part of junior high school mathematics, affecting the development of students’ mathematical thinking and mathematical abilities. The new edition of “Mathematics Curriculum Standards” clearly points out that students should master the knowledge of geometry in a comprehensive way and acquire the improvement of comprehensive literacy and the development of spatial imagination ability through the study of geometry. The idea of geometric transformation is not only a learning method that students should master, but also an important content of the new curriculum reform. It is implicit in the learning of geometric knowledge, which is a hidden target of classroom teaching and affects students’ understanding of geometric knowledge . First, the junior high school geometry analysis of the status quo Geometry is an important part of mathematics, the beginning of the second semester set up classes
