Generative artificial intelligence (AI) is increasingly being integrated into classroom teaching.This study examines the relationship between generative AI-supported classroom interaction, student engagement, and learning perception in a teaching context where AI is incorporated into regular classroom activities.Survey data were collected from 86 students and analyzed using descriptive statistics and correlational methods.The results indicate that students generally hold positive attitudes towards AI-supported classroom interaction and report overall satisfaction with their learning experience.Students particularly recognise the value of generative AI in providing timely guidance and feedback during classroom activities.Further analysis suggests that generative AI contributes to learning experience in two ways: directly, by enhancing the quality of classroom interaction, and indirectly, by promoting higher levels of student engagement.These findings provide empirical evidence that generative AI can support positive learning experiences through strengthened interaction and engagement when integrated into classroom teaching.
