摘要
自主设计型实验是我校分析化学实验教学体系的重要环节之一。本文以分析化学实验教学过程中产生的含铬废水为处理对象。要求学生通过自主查阅文献、设计实验方案、分析实验方案的可行性,再进行实验探究,并对实验结果进行综合分析。该教学过程的实施,不仅培养了学生分析和解决复杂问题能力,而且培养了他们的创新思维意识。
Self-design experiment is one of the important links in the teaching system of analytical chemistry laboratory in our university. In this paper, the chromium-bearing wastewater produced in the teaching process of analytical chemistry lab class is taken as the treatment object. Students are required to independently consult the literature, design their experimental schemes, and evaluate the feasibility of their schemes. On this basis, the selfdesign experiments are carried out, and the harvested results are analyzed and evaluated. The implementation of the teaching process trains not only the students’ ability to analyze and solve problems, but also their innovative thinking consciousness.
