The document discusses and compares the ADDIE and Dick & Carey instructional design models. It notes that ADDIE is a traditional linear model with 5 phases, while Dick & Carey is more interactive with 10 phases and evaluation after each step. Both aim to view instruction as a system, but Dick & Carey requires clear learning objectives and cannot skip steps. The document concludes that instructional designers should consider the models' characteristics to select the best approach for their needs.
