This document compares two instructional design models: the ADDIE model and the Dick and Carey model. Both models follow similar steps of analysis, design, development, implementation, and evaluation. The key differences are that the ADDIE model has 5 broad steps while the Dick and Carey model has 10 more specific steps. Additionally, the Dick and Carey model features formative evaluation throughout the process, while the ADDIE model only includes summative evaluation at the end. The advantage of ADDIE is its simplicity, while its disadvantage is only evaluating once. Dick and Carey's advantage is continuous evaluation, while its disadvantage is perceived complexity.
