Effectiveness Evaluation of Online Teaching Based on CRITIC-VIKOR Technology

Abstract

Abstract—A system including 18 second-level indexes was constructed first from three aspects to further scientifically evaluate the effectiveness of online teaching. These aspects are the effectiveness of technical support, students’ online learning, and teachers’ online teaching. Moreover, the weights of indexes affecting the effectiveness of online teaching were calculated using the improved CRITIC (Criteria Importance Though Intercrieria Correlation) method, followed by the VIKOR (VIseKriterijumska Optimizacija I Kompromisno Resenje)-based effectiveness evaluation for the online teaching of five majors, including microbiology in Henan Agricultural University. Results show that three indexes—repeated playback promotes knowledge review and consolidation (X2-2), breaking through time-space restriction facilitates learning whenever and wherever possible (X2-1), and good teacher–student and student–student interaction (X3-2)—rank top three in weight. The Q value measured using the VIKOR method reflects the best effectiveness of online microbiology teaching. The CRITIC-weighted VIKOR online teaching effectiveness evaluation model is proved to be flexible and feasible in evaluating the online teaching effectiveness of different subjects, such as schools, majors, and students. The research findings are of specific guiding significance for scientifically adjusting online teaching behaviors and carrying out online teaching activities. Moreover, this research can promote the application of big data analysis in online teaching effectiveness analysis and be of reference value for the process data evaluation of students’ online learning.
