Emerging themes in distance learning research and practice: some food for thought
回顾了过去五年远程学习研究论文，归纳出定义、学习理论、协作方式、学习者特征和效果测量等主要主题，指出实践已领先研究，呼吁更多研究识别关键成功因素。
With the rapid spread of distance learning as a medium for delivering instruction, the practice of distance learning has outpaced research. This paper describes major themes identified in a review of selected research papers published in the past five years. Themes include the following: definitions of distance learning and why it should be studied; identification of the major learning theories on which research is based; how collaboration can be achieved via distance learning; the role that learner characteristics play in the success of distance learning systems, and issues related to measuring the effectiveness of distance learning. The authors conclude that more research is needed to identify critical success factors for distance learning.
