研究型化学实验教学的实践与探索

提出了研究型实验教学内容的设计和选择,并探讨了如何培养学生科研能力和吸引学生学习兴趣的几种途径,以此促进学生学习的主动性和创造性,提高实验教学质量。通过"染料敏化太阳能电池的制作及性能研究"和"聚氯化铁絮凝剂的制备及高浊度水的处理"2个实验,逐步指导学生查阅相关文献;讨论实验意义、可行性及实验中可能遇到的问题;以组为单位进行实验,汇总数据,讨论结果;根据实验结果写出实验报告,对实验结果进行总结和展望。研究型实验吸引了学生对科学研究的兴趣,培养了学生文献检索的能力,巩固了学生课堂所学的知识,让学生初步体验了科学研究的过程。既提高了学生独立处理科学问题的能力,又培养了学生的团队协作能力。

Practice and exploration on teaching of research chemistry experiment

The design and selection on research experiment teaching were put forward tentatively. Several ways about how to cultivate students＇ capacity for scientific research and attract students＇ learning interest were discussed in detail, with the purpose of promoting the initiative and creativity of learning and improving the quality of experiment teaching. Through the two experiments, which are ＂The Research of Production and Property of DSSC ＂ and ＂The Preparation of Poly Ferric Chloride Flocculant and Treatment of High Turbidity Water＂, students would manage to look up literature, discuss the meaning and feasibility of the experiments, and solve relevant problems under teachers＇ guidance. Students would do experiments in groups to summarize and discuss the data, finish the report according to the experiments＇ results and draw a final conclusion. This research experiment attracts students＇ learning interests, develops their capacity for looking up documents, and consolidates what have been learned from class. Moreover, it also makes students experience the process of scientific research preliminarily. The research experiment not only improves the students＇ ability of dealing with scientific problem independently but also cultivates their teamwork.
