The document compares and contrasts the ADDIE and Dick and Carey instructional design models. Both models follow a systematic process and include formative evaluation steps. The key differences are that the Dick and Carey model has more detailed steps and incorporates evaluation throughout each phase, while ADDIE includes evaluation as its own final phase. The ADDIE model is more flexible but can deter creativity. The Dick and Carey model requires clear learning objectives but assumes all components are essential.
