中学化学实验评价方法的对比和应用研究
发布时间：2019-01-23 07:17
【摘要】：随着新一轮课程的改革,化学实验教学在化学教学中的地位越来越重要,然而在当前化学教学实践中,化学实验教学还存在很多问题。存在这些问题的主要原因在于应试教育条件下化学实验评价方法的不完善。目前,虽然我国中学化学中已经提出了一些与国际接轨的化学实验评价方法,但由于这些方法存在很多的不足,如:对化学实验教学重要性认识不清、对化学实验评价重视不够和化学实验评价不科学、不系统、操作性不强等问题。这些问题需要进一步解决,需要在评价理念、方式、方法以及评价内容和标准诸方面不断地改进与提高。本文首先将ICh O、AP、IB、英国A-level等国际重要化学考试的实验评价方法与我国的化学实验评价方法进行了对比研究,整理出了可供借鉴的化学实验评价方法的部分内容。其次通过对四川大学化学学院大二学生和四川省内53名化学教师的调查,深入了解和研究了中学化学实验评价方法的现状和师生改进实验评价的愿望和建议,初步验证了对比研究得出的结论。再次根据分析结果并结合化学新课程的要求,将对比研究结论应用于四川大学附属中学的实际化学实验评价,在实验中对重要结论进行了完善和修正。最后通过对比研究、调查与应用研究的结果再次进行分析整理,提出了四点完善和改进我国中学化学实验评价的设想。这些设想既有国外经验作为例证,也有国内调查数据和应用研究作为支撑,希望能对完善我国中学化学实验评价方法有所贡献。
[Abstract]:With the reform of the new curriculum, chemistry experiment teaching is more and more important in chemistry teaching. However, in the current chemistry teaching practice, there are still many problems in chemistry experiment teaching. The main reason for these problems lies in the imperfection of chemical experiment evaluation method under examination-oriented education. At present, although some chemical experiment evaluation methods have been put forward in middle school chemistry of our country, but because of these methods there are many shortcomings, for example, the importance of chemistry experiment teaching is not clear, The evaluation of chemical experiment is not paid enough attention and the evaluation of chemical experiment is not scientific, systematic and operational. These problems need to be solved further, and the evaluation ideas, methods, contents and standards should be continuously improved and improved. In this paper, the experimental evaluation methods of international important chemical tests, such as ICh Oppb, A-level and so on, are compared with those of our country, and some contents of the evaluation methods for chemical experiments that can be used for reference are put forward in this paper. Secondly, through the investigation of the sophomore students in the School of Chemistry of Sichuan University and 53 chemistry teachers in Sichuan Province, the present situation of chemical experiment evaluation methods in middle schools and the wishes and suggestions of teachers and students to improve the experimental evaluation are deeply understood and studied. The conclusion of the comparative study is preliminarily verified. According to the results of the analysis and the requirements of the new chemistry curriculum, the comparative research conclusions are applied to the practical chemical experiment evaluation of the secondary schools affiliated to Sichuan University, and the important conclusions are perfected and revised in the experiment. Finally, through comparative study, the results of investigation and application research are analyzed and sorted again, and four suggestions are put forward to perfect and improve the evaluation of chemistry experiment in middle school in our country. These ideas are both exemplified by foreign experience and supported by domestic investigation data and applied research. It is hoped that these ideas will contribute to the improvement of the evaluation methods of chemical experiments in middle schools in China.
