Research on Teacher's Metadiscourse Interaction in College English Micro-lectures
Micro-lectures,a common form in college English teaching,involve a unidirectional process of information transmission by teachers through videos.Metadiscourse,which focuses on the relationship among discourse producers,users,and the discourse itself,provides a powerful perspective for analyzing how teachers in micro-lectures actively construct teacher-student interactive relationships through language.This paper,by analyzing micro-lecture videos from ten teachers,examines the crucial role played by different types of metadiscourse in fostering teacher-student interactions and establishing communication channels.
