- Summary:
-
Instructional cross-media experiments are difficult to design because they involve complex instructional systems which include variables that are hard to control. Strict controls can be approached in the laboratory setting, but as the experimenter moves from the laboratory to the field study, especially in developing countries, concessions to realism must be made. In these situations, the experimenter finds his control over conditions eroded by geographic isolation and the lack of financing and facilities, by the degree of commitment and interference of administrators, and by the moral imperative for total reform which denies the opportunity to exclude control groups from innovation. Nevertheless, cross-media field studies can be useful in evaluating the success of new systems, for conducting pilot studies, and for planning purposes, for what they lose in controls they gain in realism. Such studies are particularly effective when the researcher is aware of necessary trade-offs, provides the client group with descriptive and cost data on a full range of dependent variables, develops local tests, and helps to designate the maximally effective instructional system under a given set of environmental conditions.
