Research on the evaluation of English teaching quality based on grey relational analysis

Online English teaching app is a platform that can make students more flexible and effective in mastering English skills. At the same time, teachers can be more targeted and motivated in the classroom, making the guidance more targeted. This paper sorts out the basic theory of teaching quality evaluation and introduces the advantages and disadvantages of the more commonly used evaluation methods such as fuzzy comprehensive evaluation, AHP and BP neural network evaluation. In this paper, the relevant information of three random teachers in the English online teaching platform was obtained by means of a questionnaire survey, and then the teaching quality of the three teachers on the English Teaching Platform (EOTP) was simulated and analyzed in MATLAB, and the simulation results were compared with the teaching quality of the three teachers. The results of fuzzy comprehensive evaluation method and BP neural network evaluation method are compared and analyzed. The analysis results show that the teaching evaluation model based on grey relational analysis has certain rationality and feasibility.
