With the rapid development of AIGC (Artificial Intelligence Generated Content) technology in the field of education, its impact on students’ learning experience and cognitive development has garnered increasing attention. This study adopts quantitative research methods such as questionnaire surveys, targeting college students as the research subjects. By constructing a structured questionnaire with a scale and collecting valid data, this study processes the data through methods such as correlation analysis after analyzing reliability and validity. The research results indicate that the application of AIGC in classroom teaching significantly enhances college students’ self-efficacy. AIGC effectively boosts students’ self-efficacy by providing personalized learning support, instant feedback, and an interactive learning environment.
