In recent years, the booming higher vocational education sector in China has compelled vocational colleges to prioritize the academic achievement of higher vocational students. Our research aims to delve into the factors that shape culinary students' learning performance, drawing insights from a case study and empirical analysis of higher vocational students in Zhejiang, China. Prior to administering the questionnaire, we employed item-objective congruence (IOC) and a pilot test of Cronbach's alpha to ensure the content's validity and reliability. We selected 80 culinary students from a Zhejiang-based higher vocational institution using intervention methods for our study. We employed both qualitative and quantitative techniques to evaluate the efficacy of the intervention. Three phases structured the study: pre-IDI intervention design and implementation, IDI intervention, and post-IDI intervention. The findings indicated that self-efficacy, behavioral engagement, cognitive engagement, emotional engagement, and student-instructor interaction significantly impact learning performance. We validated the five proposed hypotheses, thereby achieving the research objectives. The study recommends that educators in higher vocational universities and colleges prioritize these factors and teaching methods to enhance student learning performance, taking heed of the study's outcomes.
