This document discusses two common instructional design models: the ADDIE model and the Dick and Carey model. The ADDIE model is a five step process of analyze, design, develop, implement, and evaluate. It is widely used and accepted but allows flexibility between steps. The Dick and Carey model has ten more detailed steps including identifying goals, analyzing learners/context, developing objectives and assessments, and conducting formative and summative evaluations. Both models focus on inputs, outputs, and designing curriculum to achieve learning goals, and emphasize evaluation and revision to improve training.
