化学是一门以实验为基础的学科。学生通过实验可以更直观地认识化学反应、理解化学原理,实验教学是化学教学中重要的一个组成部分,合理有效的实验可以达到辅助教学、提高课堂教学效果的目的。随着科技水平的提高和教学手段的多样化,合理地利用电教手段可以为我们解决实验教学中容易出现的一些困扰并起到丰富化学课堂、增强实验效果和拓展实验内容等方面的特殊作用。
Chemistry is an experiment-based discipline. Through experiments, students can more intuitively understand chemical reactions and understand the principles of chemistry. Experimental teaching is an important part of chemistry teaching. Reasonable and effective experiments can achieve the goal of assisting teaching and improving the effectiveness of classroom teaching. With the improvement of science and technology and diversification of teaching methods, the rational use of audio-visual means can solve some troubles that easily appear in experiment teaching and play a special role in enriching chemistry class, enhancing experimental results and expanding experimental contents.
