K-12 online learning journal articles: trends from two decades of scholarship

In this study, we examined the research literature in the field of K-12 online learning to identify the leading scholars, journals, top cited articles, research methods, and topics in this field of inquiry. Our research process involved collecting a corpus of journal articles focused on K-12 online and distance learning; categorizing these articles according to their research methodologies; analyzing trends not only in methodologies employed but also in authorship, citations, journals, and topics addressed. We found the field of K-12 online learning to be growing rapidly in recent years with acceleration not only of new articles but especially of new authors. We also found the field began primarily with emphasizing theoretical articles but is now maturing and emphasizing increasingly more data-based articles. We found K-12 online learning scholarship is scattered among many journals, providing rich opportunities for scholars while also making it more difficult to discern trends across the discipline.
