The document discusses and compares two instructional design models: the ADDIE model and the Dick and Carey model. The ADDIE model consists of 5 sequential stages - analysis, design, development, implementation, and evaluation. In contrast, the Dick and Carey model has 10 iterative phases and emphasizes clear, measurable learning objectives. Both models take a systems approach but differ in their number of steps and evaluation processes. Overall, the document concludes that both models can be useful tools for instructional designers to create concise and engaging training materials.
