摘　　要：笔者以"凝固点下降法测定溶质的摩尔质量""电解质溶液的电导测定""表面张力的测定"三个实验为例,通过对多批次学生的实验数据和结果进行跟踪、统计和分析,首次阐述了建立物理化学实验差异化考核评分标准体系的必要性,并根据不同实验的内容和特点,初步建立了各实验的评分标准等级。差异化评分标准体系的建立能有效激发学生自主学习的积极主动性,进一步规范任课教师的评分准则,进而提高物理化学实验的教学质量。For the first time, Differentiation Grading Standard System（DGSS） was put forward and carried out in the course of Physical Chemistry Experiment through multi-batch statistical results of a large number of students＇ experimental data by taking three example experiments as examples, including determining molecular weight of naphthaline with freezing point depression, determining conductance of aqueous electrolyte solutions of acetic acid and determining surface tension of aqueous solutions of n-butyl alcohol. Necessity of DGSS in the course of Physical Chemistry Experiment was also expounded in details. Construction and implementation of DGSS can stimulate the initiative of students＇ autonomous learning, restrict the normative grading standard of the teachers and can therefore improve the teaching quality.
