课堂教学从钻研教材开始。只有深刻理解教 材,准备充分,上课时才能轻松自如,深入浅出。 讲课深入浅出是很重要的。所谓深入浅出就是对 知识结构的各个环节了解深刻,讲解生动、易懂。 最怕的是深入深出,起点高,讲解也深,学生听不 懂。最糟的是浅入浅出,学生越听越没有兴趣。只 有对教材的钻研达到一定的深度、广度,才能在课 堂上轻松面对教学中的任何问题。 Class teaching begins with studying textbooks. Only a profound understanding of teaching materials, preparation, class can easily ease, explain profound theories in simple language. Lecture easy to understand is very important. The so-called easy to understand is profound understanding of all aspects of the structure of knowledge, vivid, easy to understand. What we are most afraid of is deep penetration, high starting point, deep explanation, students do not understand. The worst is easy to understand, the more the students listen less interesting. Only the study of textbooks to reach a certain depth, breadth, in the classroom can easily face any problems in teaching.
