My definition of UDL, adapted from Bowe, emphasizes expanding three vectors of the classroom dynamic. One focus is on how the teacher instructs—­how we deliver information and engage students in the most accessible manner possible. Another focus is on active learning by students—­varied forms of applied and interactive learning, with course materials and within a diverse community. The third focus is on multiple options for student design, delivery, and expression—multiple ways for students to show what they know, share their ideas, compose for varying audiences, and then revise. These foci necessitate less teacher dictatorship and greater communal shaping.
