Abstract
In order to further promote the innovative design of College English teaching and improve the level of English teaching, this paper proposes a college English teaching evaluation system based on multimodal discourse analysis. Firstly, a new teaching evaluation model was constructed to deeply explore the problems of multimodal discourse in English textbooks from the perspective of multimodal discourse analysis. Secondly, applying multimodal discourse analysis to English teaching evaluation provides new perspectives and methods for evaluation. Finally, an English teaching evaluation algorithm and scheme were designed based on the MATLAB 7.0 environment, and the feasibility of the algorithm was tested through alpha coefficient. The consistency of teachers’ evaluation of students’ learning status was determined, and the English teaching evaluation mode was innovated. The results show that the alpha coefficient is between 0.00 and 1.00, which also shows that there is a strong consistency between the two projects. At the same time, it also shows the feasibility of the system and the effectiveness of the algorithm.
