Transactional Distance

online learning is most effective when the perceived pedagogical distance between the instructor and students in the course is minimized with increased interaction; Interaction occurs through learner-instructor communication, learner-learner collaboration, and learner-content engagement. All three levels of interaction have important implications for effective online learning

Community of Inquiry (CoI)

The Community of Inquiry theoretical framework focuses on the degree of presence in the online learning environment. Presence is vital to student success in online courses. There are three types of presence that must be maintained: 1. Social presence to increase learners’ sense of community in the online environment, 2. Cognitive presence to enable learners to construct meaning from the online experience, and 3. Teaching presence to increase learner perception of the instructor’s ability to provide structure and direction in the online environment
