Keep in mind that designing your class in a way that is accessible to persons with disabilities may also be beneficial to persons without disabilities. For example, a student might be in a noisy lab when watching a video. In this situation, captions on the video would be helpful for that student as well as a student who is hard of hearing. Additionally, using technology that is easy to navigate and accessible by screen readers will not only help students who are blind but it will also help all students become comfortable with the program more quickly. Several good resources on Universal Design of Instruction are listed below.
