The document discusses two instructional design models: the ADDIE model and the ASSURE model. The ADDIE model consists of five phases - Analysis, Design, Development, Implementation, and Evaluation. It is a flexible guideline for building effective training. The ASSURE model focuses on analyzing learners, stating objectives, selecting appropriate methods and materials, utilizing the methods and materials, requiring learner participation, and evaluating outcomes. Both models provide stages for instructional designers to follow in order to help learners achieve instructional goals. The ADDIE model emphasizes formative and summative evaluation, while the ASSURE model incorporates learner participation and the integration of technology into the design process.
