Instructional Design Models An instructional design model is a framework for instruction, used by many trainers and educators, that helps identify and explain the steps associated with the process of instruction. (Rosenberg, 1982) Instructional design models attempt to identify student needs and provide a process by which a course will be taught. The steps within the model help instructors break down the courses they teach into a series of steps or parts to ensure that the intended learning outcomes are achieved. Many different instructional design models have been written, including the Dick & Carey model, ADDIE, and the Kemp ISD model; however, for the purposes of this article, the primary focus will be on comparing the Dick & Carey instructional design model to the ADDIE model. (Andrews & Goodson, 1980) The ADDIE (Analysis, Design, Development, Implement, and Evaluate) model, although its origin is unknown, is a five-part instructional design model, upon which many current instructional design theories are based . Although the ADDIE model is considered by some to be the original instructional design model, some weaknesses in the design have been noted, perhaps the springboard for the development of more detailed instructional design plans. (Learning Theories, 2011) The stages of this model incorporate more in each subsequent step. The five phases are not specifically broken down into smaller sections. This has been considered by some to be a design flaw, while others, such as Dick & Carey, have taken steps to further refine these 5 phases. Analysis is the first phase of ADDIE models and includes both the definition of educational objectives and educational purpose. In this part…half of the article…sequence, it appears that we continue to provide a framework for educators to follow in developing effective curricula. Their relevance seems to have survived over the years, and despite some revisions, the significance of design patterns remains constant in the field of instructional design and instruction.
