Professor Shin-Jae Park of the College of Liberal Arts at Kookmin University has developed a “Teacher-AI Co-orchestration (TAC) model for English writing feedback” and is conducting research to apply it to actual university classes.

This study aims to scientifically analyze the effectiveness and utilization of AI-based feedback and build a hybrid feedback system that contributes to improving students' writing skills by combining it with teachers' higher-order feedback.

The study consists of three stages. ▲In the theoretical stage, a meta-analysis encompassing recent domestic and international studies will be conducted to derive the effectiveness of AI feedback and key moderating variables. ▲In the empirical stage, the current state of AI feedback utilization in actual university settings will be quantitatively and qualitatively investigated to examine educational effects. ▲In the practical stage, the TAC model, which integrates AI's initial feedback and instructors' supplementary feedback, will be designed and its effectiveness validated.

In particular, the TAC model is evaluated as having both practical applicability and scalability, as it combines large language models (LLMs) and reinforcement learning algorithms to provide customized feedback tailored to learners' characteristics, and includes instructor dashboards and training programs.

Professor Park stated, “Even in the age of AI, the role of human instructors will never diminish; rather, more sophisticated instructional design and strategies will be required. We aim to bring about real change in the field of education by implementing a practical model that demonstrates the potential for collaboration between AI and instructors.”

This research has been selected for the 2025 Korea Research Foundation's New Researchers Support Program in the humanities and will receive a total of 60 million won in research funding over three years. Professor Park was previously selected for the New Researcher Support Program (multi-year type) in 2022 for his research applying machine learning techniques to comprehensively analyze the complexity, accuracy, fluency (CAF), and vocabulary of English learners.

It is rare for a researcher to be selected for the Ministry of Education's multi-year program twice in a row, and this is a result of Professor Park's continuous research capabilities and practical contributions to the field of education being officially recognized.

The research results will be widely shared with the education community and academic community through presentations at relevant academic conferences and publications in academic journals.
