物理化学实验量化评价体系的构建

Construction of a Quantitative Evaluation System for Physical Chemistry Experiment

基于"量变是质变的基础"这一哲学思想,结合物理化学实验教学中存在的问题,对实验考核制度进行了探索与实践,提出一种构建物理化学实验量化评价体系的思路和方法。把学生的实验预习、实验操作、实验综合素质、实验报告、实验小论文等项目作为评价的内容。以过程评价表为依托,对学生的学习成果进行必要的"量化"测量,从而建立一套多指标的物理化学实验课程量化评价体系。该量化评价体系的实施能规范学生实验操作,激发学生学习物理化学实验的主动性,提高学生观察力、分析问题和解决问题的能力,从而培养学生的创新能力。

This paper presented a method to improve an evaluation system for physical chemistry experiment based on a philosophical thought that "quantity is the precondition of qualitative change " and problems presented in physical chemistry teaching. The quantitative evaluation for physical chemistry experiment course adopted a multi-index system,and comprehensive evaluation method. This method employed preview reports,experiment operation,comprehensive quality,experiment reports and experiment thesis as items of the evaluation contents. Process-evaluation tables were applied to measure the students’ learning outcome by the multi-index system. The application of the evaluation system can regulate the experimental operation skill of students,stimulate learning enthusiasm,develop the ability of analyziing and solving problems,so as to cultivate students’ innovation ability.
