The document discusses barriers to retention and success in online higher education courses and proposes solutions. It reviews studies conducted at Rensselaer Polytechnic, Tidewater Community College, and Tomball College that identified issues such as lack of interaction, feedback, time management and computer skills. The studies found that providing more instructor support, training, and standardized course formats improved completion rates, lowered dropout rates and increased student and faculty satisfaction with online courses. The document advocates for policies, resources and training to address transactional distance, technical problems, student support services and other barriers in order to improve online education.
