概念教学在中学数学教学中占有很重要的地位，正确地掌握数学概念是培养学生的逻辑思维能力、空间想象能力、分析问题和解决问题能力的前提条件，而学生（特别是刚升入高中的高一学生）对数学概念的理解，常常带有片面性、孤立性和模糊性．本文谈一谈笔者在立体几何教学中...
Conceptual teaching plays an important role in mathematics teaching in middle schools. Correctly mastering mathematical concepts is a prerequisite for cultivating students’ logical thinking ability, spatial imagination ability, problem analysis, and problem solving ability. Students (especially those who have just entered high school High school students’ understanding of mathematical concepts is often one-sided, isolated, and vague. This article talks about the author in the three-dimensional geometry teaching...
