Mock Impoliteness in Online Courses: A Study of Liu Xiaoyan’s PEE Classes

Abstract

Mock impoliteness known as banter refers to the offensive way of being friendly. Many researches have examined mock impoliteness in sitcoms, talk shows and social platforms such as Wechat and Weibo, as well as in live streaming commerce. However, its application in educational settings remains underexplored. Drawing on Liu Xiaoyan’s Postgraduate Entrance Examination (PEE) online courses, this study investigates three strategies in using mock impoliteness: (1) explaining key points, (2) motivating students and (3) engaging in self-deprecation. Through qualitative analysis, the findings demonstrate effective functions of mock impoliteness in alleviating tension and stimulating motivation, thereby enriching our understanding of strategic teacher discourse in digital environments, which may provide pedagogical implications.
