摘要：AbstractA growing number of studies have been carried out to understand learning and teaching activities in online learning environments (OLEs) and to design effective OLEs for meaningful learning in higher education. Although there were a small number of studies to provide research trends in educational technology in regards to research topics, methods, and researchers, more research is necessary to help educators to understand new trends and issues of OLEs in higher education. This study intends to provide an overview of practical and theoretical issues pertaining to OLEs by analyzing literature recently published in peer-reviewed journals. The present study qualitatively analyzed research questions and purposes to identify themes of OLEs in higher education. The OLE research topics were grouped into three major themes: (1) participants, (2) micro-level environments, and (3) macro-level environments. The findings are followed by discussion of an ecological approach as a new theoretical framework to guide future OLE research and practice.
