Typically, instructor comfort with the design of a control pad is a critical element when an institution is evaluating different brands of compressed video equipment. As with Audiographic Learning, an instructor wanting to use Compressed Video Learning needs to know how to manipulate some of the equipment controls in order to plan a learning session. When you deliver the session, it is a good idea to have a second person operate the control pad, leaving you free to concentrate on learning issues. A learner can readily perform that function at each site. A technician is needed to service the equipment.
Many organizations have a technician on call during learning events.
As everyone gains experience, they tend to call the technician less and less frequently. One specific challenge to orderly interaction occurs when switching between various sites in compressed video conferencing. The switching is typically sound-driven, which means the bridge connecting the sites shows a picture of the site that has requested the floor. CVL has a number of strengths but requires that we pay attention to several key issues. Table 9.1 shows our summary of 10 strengths and five issues.
