Universal Design for Learning: A Practical Guide
It is extremely important to keep the users in your mind when it comes to accounting for jaggedness and designing proactively in a UDL framework. UDL is user-centred because it is critical to understand the needs, gaps, barriers, and goals that any users may experience, which includes both the instructors and students.
But why is UDL for both of the students AND for you as the instructor? Because classrooms are systems. They are ecologies. Everyone, including you, is using the design that you created so we want to be sure that users on both sides of the design are getting their gaps filled, their goals met, and are leaving with a sense of satisfaction in teaching, learning, and reflection.
