常言道:“万事开头难”·要想上好一堂数学课,良好的开端是成功的一半·二十几年来,我一直努力探索和试验,总结出了数学课的八种导入方法·一、温固知新导入法温固知新的教学方法,可以将新旧知识有机的结合起来,使学生从旧知识的复习中自然获得新知识·例如:在讲切割线定理时, As the saying goes: “Everything is difficult at first.” To start a good math class, a good beginning is half the battle. In the past 20 years or so, I have been trying hard to explore and experiment, and I have summarized eight introduction methods for mathematics classes. Wen Guzhi’s new introduction method, Wen Wenzhi’s new teaching method, can combine the old and new knowledge organically and enable students to naturally acquire new knowledge from the review of old knowledge. For example: When speaking about the cutting line theorem,
