The document compares and contrasts the ADDIE model and the Dick and Carey model, which are two instructional design models. The ADDIE model consists of 5 sequential phases - analysis, design, development, implementation, and evaluation. The Dick and Carey model promotes a systems view of instruction and has 10 phases including identifying goals, analyzing learners/contexts, developing objectives, and conducting formative and summative evaluations. Both models focus on input, output, and an iterative process. A key difference is the Dick and Carey model has more detailed phases and two stages of evaluation.
