+  abstract = {The emergence of e-learning comes at a time when education and training are undergoing important transformations. The teacher-centered model that has dominated instruction for centuries is slowly giving way to a learner-centered model with instructors in the roles of facilitators or "guides on the side." E-learning is no exception. But e-learning's use doesn't preclude facilitators' responsibilities for structuring learning experiences. The effectiveness and success of e-learning programs are dependent on facilitators' roles in delivering and managing instruction. One of the leading conceptualizers in the field of distance learning, Zane Berge, broke down an instructor's role in computer conferencing into four separate parts. I propose a similar model, in which an e-learning facilitator "wears four pairs of shoes"{\textendash}acting as instructor, social director, program manager, and technical assistant.}
