过程性评价因素与期末成绩的相关分析和通径分析

Correlation and path analysis between formative assessment factors and final grade

目的通过对过程性评价因素课程视频、章节测验、作业、课堂互动等的相关分析,探究各因素与期末成绩的相关性,为选择合适的过程性评价因素提供理论依据。方法以江苏卫生健康职业学院2022年春季学期影像电子学基础课程学习的30名学生的考核成绩为数据基础,使用相关分析、回归分析和通径分析对过程性评价因素进行分析。结果课堂互动的标准差率最大,为60.50%;作业的标准差率最小,为7.88%。各因素与期末成绩均为正相关。结论作业和章节学习次数对期末成绩的直接影响较小,指导教师应修改或完善过程性评价因素,改进教学策略。

Objective To explore the correlation between formative assessment factors and final grade through the correlation analysis of course video,chapter test,homework and classroom interaction of process evaluation factors,and provides theoretical basis for selecting appropriate formative assessment factors.Methods Based on the examination results of 30 students studying the basic course of imaging electronics in the spring semester of 2022 at Jiangsu Health Vocational College,the formative assessment factors were analyzed by the correlation analysis,regression analysis,and path analysis.Results The standard deviation of classroom interaction was the highest(60.50%)and that of homework was the lowest(7.88%).All factors are positively correlated with the final grade.Conclusions Path analysis found that the frequency of homework and chapter study has relatively little direct influence on the final grade,so teachers should be instructed to modify or improve formative assessment factors and improve teaching strategies.
