This document compares and contrasts the ADDIE and Dick and Carey instructional design models. The ADDIE model has 5 phases - analysis, design, development, implementation, and evaluation. It is concise and good for training tasks but may not work as well for complex courses. The Dick and Carey model has 10 phases including identifying goals, analyzing skills needed, determining entry behaviors, setting objectives, developing tests, designing instructional strategies and materials, and ongoing evaluations. It is more flexible and suitable for large course content but has more evaluation points. A key difference is that the ADDIE model may be better for task training while Dick and Carey is more appropriate for substantive course content like in schools or universities.
