Gerlach & Ely: Systematic Approach



Gerlach & Ely's model of instructional design is a model that helps support media-rich instruction in student centered classrooms. In this model, objectives and content are developed synchronously, indicating that objectives often change in response to the content taught. In particular, this model focuses on concrete teaching, rather than esoteric objectives that are difficult to apply.
