A Review of the Instructional Design Models

Before we discuss what instructional design models (IDM) are, it is important to first define itself. Its also referred to as Instructional Systems Design (ISD), is the process of creating instructional experiences that make the acquisition of knowledge and skill more efficient and effective. The instructional design discipline grew out of World War II, when the U.S. military needed to quickly train large numbers of personnel to perform various tasks.

While the terms Instructional Technology and Educational Technology are frequently used interchangeably, they are not exactly the same. The Association for Educational Communications and Technology (AECT) defines Instructional technology as “the theory and practice of design, development, utilization, management, and evaluation of processes and resources for learning,” while Educational Technology is defined as “study and ethical practice of facilitating learning and improving performance by creating, using and managing appropriate technological processes and resources.”
With the key definitions now out of the way, let us examine instructional design models. First, a model is a representation of a complex entity or phenomenon, whose purpose is to objective understanding of what it represents. Models help the designer to visualize the problem at hand, and to then to break it down into smaller, more manageable units.
