Carey and Carey define instructional strategy as “the process of sequencing and organizing content, specifying learning activities, and deciding how to deliver the content and activities” (Dick & Carey, 2008, p. 67).
Instructional strategy has four main elements. Media selection is the fourth element and involves the selection of the best delivery system that will help to achieve the intended goals. “Media constitutes the physical elements in the learning environment with which learners interact in order to learn something” (p. 98). The media selected should be compatible with the delivery systems selected.
It is possible to revise the media selected for a number of reasons. Media choices are influenced by the category of the learning objectives. For instance, with verbal delivery system, less interactive media is applicable. On the other hand, intellectual skills require interactive media so that complicated issues are simplified.
