中学化学实验改进与创新研究

On the Improvement and Innovation of the Chemistry Experiments in High School

化学实验是中学化学课程的重要组成部分,有效的实验是落实三维教学目标的关键.针对教材中部分实验存在的问题与不足进行分析,阐述了化学实验改进与创新的必要性,提出了改进化学实验一般原则,列举了几则实验改进实例.

Chemistry experiment is one of the important parts in Chemistry course in high schools. An effective ex- periment is the key factor to carry out the three-dimensional teaching objectives. This paper focuses on the analysis of the problems or deficiencies in some experiments in the teaching materials, sets forth the necessity of the improvement and innovation in Chemistry experiments and puts forward a series of general principles to improve the Chemistry experiments by presenting some living examples of the experimental improvement.
