||The ADDIE model is a generic and simplified instructional systems design (ISD) model. ADDIE is short for Analyze, Design, Develop, Implement, and Evaluate.
In the analyze phase, the instructional problem is clarified, the goals and objectives are established, and the learning environment and learner characteristics are identified. The design phase is where the intructional strategies are designed and media choices are made. In the develop phase, materials are produced according to decisions made during the design phase. The implement phase includes the testing of prototypes (with targeted audience), putting the product in full production, and training learners and instructors on how to use the product. The evaluation phase consists of two parts: formative and summative. Formative evaluation is present in each stage. Summative evaluation consists of tests for criterion-related referenced items and providing opportunities for feedback from the users.
