The document discusses instructional design. It defines instructional design as a systematic process that uses learning and instructional theory to ensure quality instruction. The process involves analyzing learning needs, developing instructional materials, and evaluating instruction and learner activities. A key model is ADDIE, which consists of five phases: analysis, design, development, implementation, and evaluation. The purpose of instructional design is to identify gaps in audience skills/knowledge and create learning experiences to address these gaps, with the goal of making learning more effective and time-efficient.
