Gerlach & Ely Instructional Model

In 1971, Vernom S. Gerlach and Donald P. Ely devised the Gerlach & Ely instructional model. This model was designed as a prescriptive instructional model and is similar to the IDI (Instructional Development Institute) model. The Gerlach & Ely model effectively illustrates the fundamental principles of teaching and learning and is suitable for K-12, as well as, higher education. Additionally, this model supports media rich instruction.

Specification of Content and Objectives

The Gerlach & Ely model begins by synchronously determining the content and objectives. Ordinarily, the content is considered prior to the objectives, because in the classroom, content is typically predetermined, however, these steps can also be conducted simultaneously (Grabowski, 2003).

Measurement of Entering Behaviors

Entry level skills and abilities are identified as a basis for determination of instruction. A concrete method of assessing entry skills is not specifically defined within this instructional model, therefore this is typically accomplished through review of records or the administration of a pre-assessment (Gerlach, 1980).

Determination of Strategies, Organization of Groups, Allocation of Time and Space, and Selection of Resources

This portion of the instructional model is comprised of five fundamental elements that are interrelated. Due to the correlational nature of each element, they are commonly addressed simultaneously (Qureshi, 2004).

Evaluation and Feedback

To evaluate effectiveness, this linear model concludes with an evaluation and feedback loop (Prestera, 1997). Following the evaluation, instruction is modified to address the specific needs of instruction.
