基础化学综合实验中学生“自主设计”的教学实践

在基础化学综合实验中,教师只提出主要原料和欲制备的产品大类,学生通过查找资料自主设计,用不同的方法、途径制备出所要求产品,并分析几种方法在操作过程、经济及环保等方面各自的优缺点,从而达到培养学生自主创新能力的目的.

Laboratory Practice of a Designed-by-Student Comprehensive Chemical Experiment

The comprehensive chemical experiments are introduced. After summarizing the advantages and drawbacks in the operation, cost, and impact on the environment based on the literature reading, students can make chemical products with a variety of methods and experimental designs starting with the raw materials provided by teachers. In such a way, the ability to bring forth new ideas is enhanced.
