摘要
Abstract
In order to use the multi-source data in the online-offline blended teaching mode to solve the problem of grade evaluation of system application courses,a method of performance assessment based on data extraction and principal component analysis is proposed.On the basis of collating multi-source data,the method of data integration is used to enhance the data dimensions and form the preliminary evaluation factors.The principal components analysis is used to extract the main components of the influencing factors,and the students'grades are evaluated with the main components as the independent variables.The experimental results show that the method of data integration gives more significant features to the multi-source data.The assessment scores obtained by means of feature extraction and principal component analysis have stronger correlation with the subjective assessment results.The constructed performance assessment method based on data integration and principal component analysis has better interpretability,which has reference significance for the course performance assessment of the system application of online-offline blended teaching mode.关键词
