摘　　要：针对虚拟仿真实验所具有的信息化与大数据特点,提出以操作过程评价、操作熟练度评价和报告评价为综合指标的评价体系。以所建设的国家级一流本科课程“跨音速压气机失速/喘振虚拟实验”为例,对虚拟仿真实验评分系统设计进行探索研究。该虚拟仿真实验评分系统通过准确度和时间数据统计,结合评价公式综合判断成绩,强调过程性评价。同时,限制同一网络地址在相同时间内的登录次数,克服实验数据抄袭和替考的问题,获得有区分度的客观的虚拟实验过程成绩。学生最后可以通过实验报告模块在线提交实验报告,通过回答主观问题来评估其理论理解水平,最终获得虚拟实验的综合成绩。学生还可以在线查询自己的成绩。实验评分系统的效果显示出虚拟仿真实验成绩统计的便捷性、广泛适用性和客观性。In response to the characteristics of informatization and big data in virtual simulation experiments,an evaluation system with comprehensive indicators including operational process evaluation,operational profi ciency evaluation,and report evaluation is proposed.Taking the construction of the national fi rst-class undergraduate course“Transonic Compressor Stall/Surge Virtual Experiment”as an example,the study explore the design of the virtual simulation experiment grading system.The virtual experiment grading system combines accuracy and time data statistics with evaluation formulas to comprehensively judge grades,emphasizing process evaluation.By limiting the number of logins for the same network address at the same time,the system overcome the problems of experimental data plagiarism and substitution,obtaining objective virtual experiment process grades with diff erentiation.Students can submit their experiment reports online through the experiment report module,answer subjective questions to evaluate their theoretical understanding,and ultimately obtain a comprehensive grade for the virtual experiment.Students can also check their grades online.The eff ectiveness of the experiment grading system demonstrates the convenience,wide applicability,and objectivity of virtual simulation experiment grade statistics.
