对比实验在高中化学概念教学中的应用研究

Research on the Application of Comparative Experiment in the Teaching of Chemical Concept in Senior Middle School

高中化学课中的实验操作是学生运用所学的化学知识展开实践探索的一个重要环节,也是学生检验化学知识原理的必经途径。文章简述实验教学的类型,并对高中化学概念教学中应用对比实验法进行探究。教师可以通过组织操作型实验活动、运用循序渐进的思维、重视学生意见的表述,运用合作教学法、运用趣味游戏等组织学生完成对比实验。

The experiment operation in the chemistry course of senior middle school is an important link for students to explore the practice by using the chemical knowledge they have learned,and also the necessary way for students to test the principles of chemical knowledge.This paper briefly introduces the types of experimental teaching and probes into the application of comparative experiment method in the teaching of senior middle school chemistry concept.Teachers can organize the operational experimental activities,use step-by-step thinking,pay attention to the expression of students'opinions,and organize students to complete the comparative experiment by cooperative teaching methods.
