初中数学教学中融入数学美的教学设计——以“垂直于弦的直径”为例
Incorporating the Teaching Design of Mathematical Beauty into Junior High School Mathematics Teaching—Taking the Example of “Perpendicular to the Diameter of the String”

“美”常常由人的感觉来发现、创造，并通过感性去感受、鉴赏。然而，数学的美是充满逻辑与理性的。人教版初中数学九年级上册《圆》是学习图形性质的基础，也是培养学生发现数学美、欣赏数学美的重要内容。本文以“垂直于弦的直径”为例，将数学的学习与审美相结合，从而提升初中学生数学学习的效率和数学课堂教学有效性。
“Beauty” is often found and created by human feeling, and is felt and appreciated through sensibility. However, mathematical beauty is full of logic and reason. “Circle”, the first volume of ninth-grade mathematics in junior high school, is the basis of learning the nature of figures and also an important content for training students to discover and appreciate mathematical beauty. Taking “perpendicular to the diameter of the string” as an example, this paper combines the learning of mathematics with the aesthetic, so as to improve the efficiency of junior high school students’ learning of mathematics and the effectiveness of mathematics classroom teaching.
