Design of Pedagogical Agent Based on Open-Source Large Language Model in Online Learning

Online learning provides an opportunity for students who are geographically and temporally constrained to access quality education. However, there are significant drawbacks to online learning, such as the lack of timely feedback for students, lack of instructor support, and lack of interaction, which creates a sense of separation between teachers and students. In recent years, a large number of researchers have confirmed the feasibility of pedagogical agents, but most of them are not intelligent enough for the task of immediate feedback. However, new technologies have emerged and large language modeling has been well developed, which excels at communicating with people. By designing a pedagogical agent based on the open-source large language model, each student can get appropriate feedback on their questions and meet their individual needs. Therefore, it is necessary to create one such pedagogical agent. In this paper, an intelligent pedagogical agent is designed in an educational video, and students can call the agent for support at any time as needed.
