The document describes several models for structuring online courses: The ILARQ model outlines 5 components - Introduction, Lesson, Application, Reflection, and Quiz. The ICare model is similar but replaces Lesson with Connect and adds an Evaluation component. The Dream model's components are Discover, Read, Explore, Apply, and Measure. The E-Class model uses Explain, Clarify, Look, Act, Share, and Self-Evaluate/Submit. Finally, the DSELASM model structures lessons around Discover/Intro, Self-Assess, Explain, Connect/Explore, Look, Act/Apply/Engage, Share, and Measure/Evaluate.
