Findings in Case studies

Just as there is no single recipe for successful teaching in the traditional classroom, there are diverse techniques which can be successful in the computer-mediated environment. However, there are some fundamental differences in teaching between the VC and the TC, stemming from the differences between the communication channels.

Hiltz [] establishes four basic principles to keep in mind for successful teaching in the VC, dealing with media richness, timely responsiveness, organisation and interaction:

Timely Responsiveness

Unlike the face-to-face medium, students will not receive an immediate response to their questions and comments. This can be very frustrating, if they are stuck in the middle of a problem. However, whereas they may have only a limited opportunity to ask questions during a few set hours a week for a TC, they can participate and receive feedback on a daily basis in the VC.

Organisation

With 20/30 students, the mass of material produced must be organised, otherwise it will become messy. The instructor must establish regular rhythms and schedules, based on dividing the course into modules, so that students can plan ahead in terms of when they will need to sign online, work due, and so that the group moves through the topics in an orderly manner.

Interaction

Probably the greatest determinant of the extent of which students feel that online model of delivery is better/worse than traditional model is the amount and quality of interaction between the instructor and students, and/or amongst students. Herein lies both the key and the challenge for being an effective teacher in the VC environment.
