This document provides an overview of universal design for educational technology. It discusses the importance of designing online courses and tools to be accessible and usable for all students, including those with disabilities. The presentation covers the legal mandates around accessibility, as well as the seven principles of universal design - equitable use, flexibility in use, simple and intuitive use, perceptible information, tolerance for error, low physical effort, and size and space for approach and use. Examples are given for how to apply these principles when evaluating courses and tools. The goal is to design learning environments that can be used by people with diverse abilities.
