研究型综合化学教学实验的探索.

Combined with the research hotspots from chemistry, materials and environment sciences in recent years, this paper explored a research-based comprehensive chemistry experiment which was designed and converted from I lie research subject "preparation grapheme through green chemical reduction of graphene oxide". This experiment could satisfy the requirements of the stability and reproducibility in teaching experiment. Through this proposed comprehensive experiment, the students could understand and grasp the structure, working principle and operation skill of UV-vis spectrometer and spectrofluorimeter, meanwhile, they also could understand the preparation methods and characterization techniques of nanomaterials, and strengthen their knowledge, experimental operation skill and comprehensive ability. The experiment has attained preferable teaching results. Moreover, according to this experiment, practical research topics were introduced into the system of chemistry experiment teaching, it contains a large number of content which the students can explore and investigate autonomously. It is found that these measures can improve the teaching quality, and develop the students’ comprehensive creative abilities, scientific literacy and research ability. [ABSTRACT FROM AUTHOR]
