1.复习导入法复习导入法是我们教师常用的一种方法,但是使用这种方法必须满足旧知识和新知识之间有一定的联系,通过复习旧知识能够很自然地引入新的课题。比如在讲化学键第二课《共价键》时,教师可以先复习提问离子键的概念、成键粒子、成键实质、成键元素,然后对比教学很自然地就能得出共价键的概念、成键粒子、成键实质、成键元素。这种方法既能联系旧知识又能迁移新知识。2.实验导入法化学是一门以实验为基础的科学,所以实验导课就显得非常
1. Review introduction method Review introduction method is a method commonly used by our teachers, but the use of this method must meet the certain relationship between the old knowledge and the new knowledge. It can naturally introduce new topics by reviewing the old knowledge. For example, in the second lesson “Covalent Bond”, the teacher may first review the concept of the ion key, the key particle, the key substance, and the key element, and then the comparison teaching can naturally come to a covalent bond. Concepts, key particles, key substance, key elements. This method can both connect old knowledge and migrate new knowledge. 2. Experimental introduction chemistry is an experiment-based science, so the experimental guidance is very
