Exploration and Practice on the Design of the Virtual Simulation Experiment Evaluation System—Based on the"Transonic Compressor Stall/Surge Virtual Experiment"
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 proficiency evaluation,and report evaluation is proposed.Taking the construction of the national first-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 differentiation.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 effectiveness of the experiment grading system demonstrates the convenience,wide applicability,and objectivity of virtual simulation experiment grade statistics.
