The ultimate goal of any student is to learn. However, having access to information is not the only essential ingredient in achieving that goal.
Education requires challenge and resistance.
Universal Design provides the challenge and resistance-requiring careful attention to the goals of any given learning experience when selecting curriculum materials and deciding what modifications are appropriate. If the goal of a teacher is to teach word decoding to a student with a learning disability, for example, having the computer read all of the words aloud could undermine learning. On the other hand, if the goal is to convey science concepts, having the computer read the text aloud could enhance the learning opportunity for the same student. Each student, with or without a disability, is unique. They also make assumptions about the differences among students across categories while missing the similarities.
