Analyzing the Effect of Task-Based Pedagogy on Learning Effectiveness in English Classroom Based on Computational Linguistic Modeling

Abstract

This paper proposes to use computational linguistic modeling to assess teaching effectiveness, with the help of technical methods such as Wasserstein distance and cosine similarity to assist in the diagnosis of teaching effectiveness. Taking the English teaching of two ordinary classes in a key high school as the research object, the impact of task-based teaching on English learning effect is analyzed. The questionnaire method was utilized to investigate the changes in students' evaluation of English learning before and after the experiment. The results show that the mean value of the total grade of the experimental class using task-based teaching is 119.4973, which is about 35 points higher than the mean value of the total grade of the control class, and the test of difference in grades shows that sig=0.00<0.05, the difference in the grades of the two classes is significant, which verifies that the task-based teaching method can effectively improve the English learning effect of the students.
