Inevitably having large‐size classes creates a huge number of challenges but also benefits that motivate the higher education institutes to recruit large‐size student bodies. This paper aims to identify the focus of scholars in this field, how the concerns have been addressed as well as a pedagogic basis for large‐class management and delivery, then further to determine gaps in the existing literature of large‐size classes. Using PRISMA, this research systematically reviews 131 articles between 1976 and 2024 on an international basis. Building upon the findings of the systematic literature review (SLR), the study introduces the Input‐Process‐Output‐Outcome (IPOO) model of education. Then, the research discusses a range of strategies proposed in academic research to effectively address the challenges posed by large class sizes. These strategies include pedagogical approaches/strategies, perception and behaviour‐based means, technological tools/strategies, and perception‐driven digitised strategies. The article identifies research gaps in the existing literature, particularly regarding stakeholders' perceptions of large class sizes. It emphasises the need for further investigation into the diverse perspectives held by stakeholders regarding the pros and cons of large class environments. The findings underscore the importance of challenging negative and neutral perceptions of large class sizes. Additionally, the study highlights the role of marketing strategies in shaping perceptions of class size and suggests avenues for future research in education business. Finally, the results of the bibliometric analysis reveal specific geographical or disciplinary focuses. The study provides insights for policymakers on developing effective policies to manage large class sizes and suggests future research avenues in education business and policy.
Context and implicationsRationale for this studyMotivated by the increasing prevalence of large class sizes in higher education institutions (HEIs) globally, driven by factors such as massification and marketisation. It aims to examine (dis)advantages associated with large classes while considering the diverse perspectives of stakeholders involved. Conducting a SLR and introducing the IPOO model, it aims to pinpoint gaps in managing large classes effectively.Why the new findings matterThe study addresses research gaps, particularly in understanding how perceptions shape educational practices. By highlighting the need to challenge negative perceptions, it emphasises their impact on outcomes and institutional strategies. Additionally, it identifies the role of marketing strategies in shaping perceptions and provides insights for education business.Implications for policy makers, stakeholders and the general publicThe study's implications span education sectors: practitioners can glean insights for managing large classes. Policymakers can utilise this research to inform the development of policies pertaining to class size regulations and resource allocation, ensuring that HEIs receive the necessary support to address challenges arising from large class sizes. Researchers are prompted to study perceptions surrounding class sizes. Funders can support research on class size perceptions, aiding evidence‐based decision making and resource distribution. Finally, the general public can benefit from increased awareness of the complexities surrounding class size dynamics, fostering a broader understanding of the challenges faced by educators and institutions in delivering quality education in large class settings.
