摘　　要：在中学几何概念教学中,教师需要对数学概念教学的意义和特征有深刻的认知,注重数学概念与现实生活的联系,创新几何概念教学的方式。该文以“直径”为例阐述基于汉字本义的教学方法,从“径”字的演变以及它在生活中的具体情境来理解直径的含义,由此激发学生的兴趣,发展其数学能力,并增强学生的文化自信。In the teaching of geometric concepts in the middle school, teachers need to have a deep understanding of the meaning and the characteristics of mathematical concepts, lay stress on the interconnection between mathematical concepts and the real life, and innovate the teaching methods of geometric concepts.This paper illustrates the method based on original meanings of Chinese characters with the teaching of the concept of diameter in geometry, which induces the meaning of diameter from the evolution of the character Jing with the specific situations involved in daily life, thereby stimulates the students’ interest in learning mathematics, develops their mathematical ability, and enhance their cultural selfconfidence.
