This document provides an overview of the ADDIE model for designing online courses. It describes the 5 phases of the model: Analysis, Design, Development, Implementation, and Evaluation. In the Analysis phase, needs are assessed through data collection and analysis to understand learners and define objectives. The Design phase involves outlining the course, modules, and learning assets. Development involves producing multimedia learning materials using design principles. Implementation delivers the course content and engages learners. Evaluation assesses how well learners met objectives and identifies improvements. The goal is continuous improvement through evaluation and revisiting each phase of the ADDIE model.
