著名的数学家波利亚说过:“一个专心、认真备课的老师往往能够拿出一个有意义但又并不复杂的题目,去帮助学生挖掘问题的各个方面,使得通过这道题,就好像通过一道门,把学生引入一个完整的理论领域。”本文记录了从一道普通题目出发的一堂探究课的实践与思考。
The well-known mathematician Polia said: “A dedicated and careful lesson preparation teacher often can come up with a meaningful but not complicated topic, to help students tap all aspects of the problem, so that through this question, Seems to go through a door to bring students into a complete theoretical field. ”" This article documents the practice and reflections of an inquiry class starting from a common subject.
