Discourse System Construction in the Digital Age: Linguistic Shifts and New Communication Norms

With the rapid development of information technology, the discourse system in the field of education is undergoing significant changes. Educational technology has not only changed the way teaching content is delivered, but also profoundly affected the language interaction between teachers and students. With the popularization of online learning platforms and virtual classrooms, traditional face-to-face communication has gradually been replaced by digital communication forms. This paper analyzes the discourse system in different teaching environments through natural language processing (NLP) technology, and combines the simulation experiment of the virtual classroom platform to explore how educational technology promotes or affects the construction of discourse system. Experimental data show that in information-based teaching, the frequency of interaction between teachers and students has increased significantly, the discourse structure has become more diversified, and the language style tends to be concise and interactive. The simulation analysis results show that the construction of discourse system in the context of informatization tends to be more in line with the needs of modern education and supports more efficient learning interaction and knowledge transfer.
