Review and Comparison of ADDIE, Rapid Prototyping, and SAM Instructional Design Models
ADDIE ADDIE was originally designed to be a linear waterfall system, although some modern interpretations have represented the process using circular flow charts. It is composed of five distinct stages, including Analysis, Design, Development, Implementation, and Evaluation. Although these distinct stages can be helpful in providing clear guidelines and structure, room for flexibility can become an issue. ADDIE mostly reserves feedback and revision for the final phase, Evaluation. Rapid Prototyping Unlike ADDIE, the Rapid Prototyping model is nonlinear and lacks the same level of distinction between stages. Instead, Rapid Prototyping emphasizes the development of an initial prototype over multiple iterations. Feedback and revision is a core part of the entire process as the prototype is continuously developed into the desired end-product as opposed to saving feedback and revision until the very end. This allows for greater flexibility in design and more involvement from users thro...
