高中数学的教学目的是使学生学好从事社会主义现代化建设和进一步学习现代科学技术所必需的数学基础知识和技能,培养学生的运算能力。《立体几何》作为高中数学的重要组成部分,既是教学中的重点,又是教学中的难点。一、上好第一堂课,激发学生学习《立体几何》这门课的兴趣 The purpose of high school mathematics teaching is to enable students to learn well the basic knowledge and skills of mathematics necessary to engage in socialist modernization and further study of modern science and technology and to cultivate students’ computing abilities. As an important part of high school mathematics, “three-dimensional geometry” is not only the focus of teaching, but also the difficulty in teaching. First, a good first class, to stimulate students to learn “three-dimensional geometry” interest in this course
