化学是一门以实验为基础的学科。本文作者利用普通而简单的两个化学实验内容进行探讨,生动有力地说明在职教师在进行化学实验教学过程中,如何科学分析实验现象的本质,揭露化学反应的规律,以及根据课常教学实际情况,恰如其分地论述化学实验操作规程。这是提高学生学习化学兴趣、扎扎实实地学好化学的一个极其重要的问题,也是教师如何通过化学实验提高教学质量的必修课。
Chemistry is an experiment-based discipline. The author of this article uses ordinary and simple two chemical experiments to explore the content, vividly and powerfully illustrates how the in-service teacher in the process of chemical experiment teaching, how to scientifically analyze the nature of experimental phenomena, expose the laws of chemical reactions, and according to the actual situation of teaching It is appropriate to discuss the chemical experiment procedures. This is an extremely important issue for improving students’ interest in chemistry and learning chemistry in a down-to-earth manner. It is also a compulsory course for teachers how to improve teaching quality through chemical experiments.
