The document discusses two instructional design models: ADDIE and Dick & Carey. ADDIE was established in 1975 by the U.S. Army and follows a linear 5-step process of analysis, design, development, implementation, and evaluation. The Dick & Carey model was created in 1978 and consists of 10 detailed steps in an iterative process that thoroughly evaluates each procedure. Both models employ input, process, output procedures and incorporate evaluation, though the Dick & Carey model is more time-consuming while ADDIE is foundational to many designs.
