For many of us in education, accessibility guidelines can be confusing. Fortunately, they can be distilled into four core principles, as captured by the acronym POUR (Perceivable, Operable, Understandable and Robust).  Many of the learning materials educators use in classrooms and labs are self-created and understanding how to make them accessible to all students including those with disabilities is critical. Experts from the National AEM Center at CAST, in collaboration with the NSF funded ATE Central project,  will offer practical, applied techniques that educators can implement right away. Instructors can build upon their higher-level understanding of the POUR core qualities to ensure their classroom materials “are accessible and work for all learners from the start, by design.”
