Exploring "Teacher-AI-Student" Teaching Model in College English Writing Courses

The rapid development of artificial intelligence (AI) technology is influencing and transforming the entire field of education. Under the background of AI-empowered education, college English instruction is undergoing a transition from the traditional Teacher-Student dual model to a tripartite Teacher-AI-Student collaborative paradigm. While this transformation brings new opportunities to college English teaching, it also presents numerous challenges. Based on the perspectives of Social Constructivism and Connectivism learning theories, this paper takes college English writing of sophomores as the research object. It analyzes the in-depth challenges faced by the "teacher-AI-student" model in the context of AI empowerment, including aspects such as teaching philosophy, technological application capabilities, role positioning of teachers and students, resource integration, and academic integrity. Combined with practical teaching cases, the paper proposes countermeasures integrating Technology Enhanced Learning, aiming to provide theoretical references and practical paths for the intelligent transformation of college English teaching.
