The question of whether a particular instructional medium should be used should also be examined in light of the instructional activity it is intended to present.
Media differ with respect to their ability to present particular instructional activities.
Some media are capable of depicting motion and sound, and other media are not. So if we are interested in accurately depicting to a potential surgeon how perform surgery, you might want to use another form of media in addition to a textbook or workbook, like adding an interactive video. Cost Effectiveness Consider both development and delivery costs. You must consider the location of trainees or students and the available delivery platforms. If most of your lesson relies on the same medium, it is a good idea to have a backup lesson plan in the case of either the media hardware or software not being available.
