Comparison And Applied Research Of The Evaluation Methods In Middle School Chemical Experiments

With the deepening reform of new chemistry curriculum, more and more attention has been paid to chemistry experiment teaching(CET). But in the current chemistry teaching practice, many problems still exist in CET. The main reason for those problems is due to the imperfect chemical experimental evaluating method under the examination-oriented education conditions. Now, our country has been trying to put forward some chemical experimental evaluation methods in line with international standards, but due to the influence of traditional ideas and the problems facing in operability, adaptability and etc.,the chemical experiment evaluation method in our country still remains to be improved. There are some issues, such as vague understanding of the importance of CET, inadequate attention of chemical experimental evaluation and lack of scientific, systematic and operational, should be solved in CET. While for solving those issues, it has to need to be continuously improved in the evaluation of idea, mode, methods, content and standard.In this paper, first, comparing research with the important international chemistry examination of ICho, AP, IB and A-level and the chemical experiment evaluation in China, some available for reference conclusions of chemical experimental method have been screened out. Then, through the research on sophomore in school of chemistry, Sichuan University and 53 chemistry teachers in Sichuan province, the present situation of middle school chemistry experiment evaluation method, and the suggestion and desire of teachers and students to improve the experiment evaluation were deeply understood and researched, which preliminary verified the conclusions in first step. Once more, according to analysis resultand requirements of chemistry new curriculum, the conclusions in contrast study were applied to the actual experimental evaluation in the affiliated high school of Sichuan University. And the important results were gradually improved and corrected in the experiment. Last, analyzing and organizing onthe basis of the results of contrast study, survey and experiment, four thoughts were put forward to improve our country’s chemical experimental evaluation. Those thoughts were not only verified by foreign experience but also supported by domestic survey and application research. Hope the study in this paper can contribute to improve the domestic chemical experimental evaluation.
