A simple way to challenge prior experience is to communicate expectations to the learner prior to instruction. A few comments at the beginning of a course can go a long way toward helping learners understand differences between broadcast television and two-way compressed video. Encourage learners to keep background noise to a minimum, for example, and let them know what to do to get your attention when they have a question or comment. Prepare learners for an active experience by assigning a pre-session activity or by beginning the lesson with a discussion. Ice breakers are important to increase comfort wi.th the technology.
