The worldwide expansion of education has brought the issue of large classes to researchers' attention. In China, following the university enrolment expansion since 1999, an increasing number of Chinese educators are faced with the issue of managing large classes efficiently. However, studies on the enrollment policy and the subsequent large class phenomenon are scarce. This study primarily examined enrolment expansion in Chinese higher education by analyzing policy documents and existing literature on both enrolment expansion and large class phenomenon. Additionally, the current study amplified the need for future research on issues pertaining to large classes that can help teachers, school managers, and policymakers devise effective strategies for addressing problems affecting teaching practice.
