ABSTRACT
Research on distance education, online learning, and blended learning are examined from the perspectives of quantitative (meta-analyses) and qualitative (meta-syntheses) systematic reviews. While not all of the reviews are outstanding examples of the best characteristics of systematic reviews, overall, they portray an interesting and informative perspective on the state of research, and its evolution over the past 15 or so years. Future directions for research and practice are presented and discussed.
