化学演示实验的教学价值研究

分析了化学演示实验教学的特点,并根据其不同的教学功能进行了分类;结合新的化学课程标准和中学化学教材,阐述了中学化学演示实验在教学中的重要价值：即引导学生在化学事实中认识化学知识的价值、在操作示范中训练实验技能的价值、对实验现象分析推理而启迪学生思维的价值以及培养学生应用化学知识解决实际问题的价值。为高师化学专业的学生正确理解和合理运用化学演示实验教学打下基础。

A Sudy of the Effects of the Demonstration Experiments in Chemistry Education

In this study,the features of the demonstration experiments are analyzed. The catalog of demonstration experiments was established based on the education functions of different experiments. The importance of the demonstration experiments is examined in this study based on the new standard of curriculum and the textbook for the middle school level chemistry course. Based on our study,the demonstration experiments can help the students to understand the knowledge deeply,to practice the experiment skill through demonstration operations,to improve the analysis capability by inspect the experiment result,and to using the chemistry knowledge for solving the problems in real- world applications. This study will benefit the college students major in chemistry education to help them correctly understanding and efficiently applying the demonstration experiment.
