课堂教学实践使我深深体会到:教师课前的准备工作,不仅要服务于上课,更要上好课。教前构思就是为上好课服务,它决不是可有可无的,是十分必要的,我们不要小看这短暂的时间所发挥的作用。 The classroom teaching practice has deeply deepened my understanding of the preparatory work for teachers: not only to attend classes, but also to take good classes. Pre-conception is to serve the good lesson. It is absolutely not necessary. It is very necessary. We should not underestimate the role of this short time.
