Component display theory
Component display theory (CDT) addresses the issue of learner control and the separation of instructional strategy from instructional content.
“Component Display Theory was an attempt to identify the components from which instructional strategies could be constructed. CDT describes instructional strategy in terms of strategy components: primary presentation forms (PPFs), secondary presentation forms (SPFs), and interdisplay relationships (IDRs). CDT identifies strategy prescriptions for different kinds of learning outcomes. Each of these prescriptions identified a best case combination of PPFs, SPFs, and IDRs for a particular kind of learning outcome. CDT was analysis oriented, emphasizing the components of instructional strategies for different kinds of instructional goals.” (Merril)
This instructional design model was developped through the Time-shared Interactive Computer Controlled Information Telelvision (TICCIT) project in the seventies.
