Mapping the dropout phenomenon in open, distance, and digital education (ODDE): A conceptual analysis

During the sudden shift towards online learning in the COVID-19 pandemic issues of low student engagement and dropout became a major concern in the mainstream of digital higher education. However, open and distance education has a long history concerning dropout research and practice. In the digital transformation, the terminologies and concepts that have been long adopted are inevitably subject to change. To understand dropout in open, distance, and digital education (ODDE), it is important to take an evidence-based approach and examine the literature to learn from previous research and experiences and to inform current practices and policies in digital education. Therefore, this study applies a conceptual analysis of the corpus yielded through the steps of a systematic literature review. Thus, the concept maps of the relevant articles on dropout and research trends between 2010 and 2022 through content analysis via text mining were created. The results indicate that student dropout and retention declined in publication during the pandemic despite remaining one of the critical issues in higher education. The main concepts indicate that most of the dropout studies focus on comparisons between face-to-face and online modalities; the learning environment and student engagement; and student support, motivation and social capital. The study concludes with a summary of key findings from dropout research in ODDE and a consideration of research desiderata.
