The document compares and contrasts the ADDIE and Dick and Carey instructional design models. The ADDIE model consists of 5 linear phases, while the Dick and Carey model has 10 iterative phases. Both models take a systems approach and include analysis, objectives, design, development, and evaluation. However, the Dick and Carey model includes more frequent evaluations throughout each phase. Strengths of the ADDIE model include flexibility, while the Dick and Carey model considers learner characteristics. Weaknesses are that both models can be time consuming and stifle creativity due to extensive planning requirements.
