Abstract
This paper reports on a four-day practical teaching session using AI-based Japanese language learning materials. The session targeted two second-year students from A University in Taiwan and consisted of 60-minute reading comprehension classes held once per day. An analysis of the use of AI materials during the practice sessions, combined with participant interviews, revealed that the materials effectively provide personalized and optimized lessons tailored to each learner's needs and proficiency levels. However, challenges for future development include designing learning procedures that account for learners' strategies, fine-tuning the difficulty levels of practice exercises, and creating diverse practice formats.
