EduChat is a large-scale language model (LLM)-based chatbot system designed for intelligent education. It provides personalized, fair, and compassionate support to teachers, students, and parents through various educational functions such as open question answering, essay assessment, Socratic teaching, and emotional support. One of its key features is the use of real-time updated corpora from the internet as an external knowledge source for open question answering. This ensures accurate and up-to-date information in responses. In terms of essay assessment, EduChat goes beyond coarse grading by offering fine-grained and comprehensive feedback. It combines the expertise of teaching professionals to provide overall scores, aspect-level ratings, and detailed comments on content, expression, paragraph structure, and overall evaluation. This allows for personalized guidance in all aspects of writing. EduChat also focuses on developing Socratic teaching capabilities rather than providing direct answers to students. Through multi-step question-and-answer interactions, it stimulates discussions, debates, evaluations,and analyses to foster advanced cognitive skills and cultivate students' autonomy in learning. Recognizing the psychological pressures faced by adolescents and children,EduChat incorporates a psychology-based emotional support framework. By simulating a psychological counselor based on emotion psychology theories like Rational Emotive Behavior Therapy (REBT)and the ABC theory (Ellis), EduChat provides personalized diagnoses and emotional support tailored to individual users' needs. The training procedure of EduChat involves two stages: fundamental capabilities acquisition and educational skills acquisition.In the first stage,the model is pre-trained on educational books and Q&A pairs to establish foundational knowledge across disciplines.Large-scale instruction tuningand open-domain dialogue datasets are also incorporated to enable basic instruction following abilityand dialogue ability. In the second stage,EduChat further hones its abilities through domain-specific training in educational skills.This ensures that it can effectively fulfill its role as an intelligent education tool,providing a comprehensive and personalized learning experience for users.

Abstract: EduChat (https://www.educhat.top/) is a large-scale language model (LLM)-based chatbot system in the education domain. Its goal is to support personalized, fair, and compassionate intelligent education, serving teachers, students, and parents. Guided by theories from psychology and education, it further strengthens educational functions such as open question answering, essay assessment, Socratic teaching, and emotional support based on the existing basic LLMs. Particularly, we learn domain-specific knowledge by pre-training on the educational corpus and stimulate various skills with tool use by fine-tuning on designed system prompts and instructions. Currently, EduChat is available online as an open-source project, with its code, data, and model parameters available on platforms (e.g., GitHub https://github.com/icalk-nlp/EduChat, Hugging Face https://huggingface.co/ecnu-icalk ). We also prepare a demonstration of its capabilities online (https://vimeo.com/851004454). This initiative aims to promote research and applications of LLMs for intelligent education.
