Research On Microclass Based On Multi-modal Discourse Analysis

Micro-lecture,a curriculum model of online education,has always been favored by the academic community because of its fine content,short time and clear theme.In recent years,with the vigorous development of the ’Internet + ’ industry,more and more education practitioners have put forward new teaching concepts and methods,and online teaching resources have been booming.As one of the curriculum models,microlecture provides students with effective knowledge input.In this context,the author focuses on Chinese micro-lecture.With the continuous development and application of information digital technology,people’s ideographic ways have changed rapidly,and micro-courses have gradually formed the current high-density modal form.In order to understand the modal application function,modal relationship combination and discourse meaning construction of micro-lecture,this paper takes 37 special prize works of Chinese students in the second to fourth national postgraduate Chinese teaching micro-lecture competition as the research object.Firstly,ELAN software is used to count and label the number of modal symbols.Secondly,the modal relationship and meaning expression in the works are analyzed.Finally,the meaning construction of the whole discourse of micro-lecture is discussed,and the concept of modal use behind the excellent works is analyzed.This study found that,first of all,in the internal modal relationship of microcourses,whether it is cultural micro-courses or grammatical micro-courses,the voice mode is dominant in the overall micro-course discourse meaning construction.Secondly,when designing modal relations,teachers should pay attention to whether the combination of modal relations follows the positive principle,and can consider using complementary relations to supplement one mode with another.In addition,the reinforcement relationship in cultural micro-courses hardly exists between words and voices.Designers often use pictures and postures to assist voices to express meaning.Finally,from the perspective of the interaction between the micro-lesson discourse and the external world,in the cultural micro-lesson and the grammar micro-lesson,the order of the proportion of meaning expression is the same,from high to low,followed by composition meaning,interactive meaning and representation meaning.
