“尝试错误”理论在分析化学实践教学中的应用

在分析化学实践教学中,运用美国心理学家桑代克提出的学习联结说＂尝试错误＂理论,提出了＂尝试错误＂教学法,即通过在实验过程有意设置障碍,引导学生去＂尝试＂错误的方法,从而启发学生发现错误、分析错误、改正错误,培养学生观察能力、分析问题、解决问题的能力;同时,通过＂尝试错误＂教学培养学生学习知识、应用知识的浓厚兴趣,激发学生主动学习、积极探索的求知欲望。＂尝试错误＂教学在分析化学实践教学中取得了很好的教学效果。

Application of ＂Attempt Mistakes＂ Theory in Analytical Chemistry Teaching

In the experimental teaching of Analytical Chemistry,the author applies the ＂Attempt Mistakes＂theory by Thorndike,American Psychologist to design some problems in the teaching process and to guide the students to attempt to find out,analyze and correct the mistakes so as to cultivate the students’ability to analyze and solve the problems. Meanwhile this approach allows the students to have more interests in learning and application,to motivate active exploration,and has made a good effect on practical teaching.
