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。几十年来,我一直努力探索和试验,总结出了数学课的几种导入方法。一、温故知新导入法温故知新的教学方法,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 the beginning.” To start a good math class, a good start is half the battle. For decades, I have been trying hard to explore and experiment, summed up several introduction methods of mathematics classes. First, learn from time to time and introduce new methods to learn new teaching methods. You can organically combine old and new knowledge so that students can naturally acquire new knowledge from the review of old knowledge. For example, when it comes to cutting line theorems,
