  • 14. Features of VC: Time of interaction Synchronous Asynchronous Type of interaction Student-student Student-teacher Student-content Student-machine Learning style Group-based Self-based learning Flexibility Anytime Anyplace Ease of access/use Speed Development Feedback Delivery Instruction Stand-alone medium Multimedia support Cost
