This does not have to be a difficult thing. If you post a video, transcribe the audio to post alongside the video or add captions for the hearing impaired. For visually impaired, be sure they know how to use readers. For videos, offer detailed explanations for what is happening if it is not self-explanatory.
There are many ways to address these issues. Students using ipods, ebooks, readers, and various programs that are available can now access more information than ever - regardless of their special needs status. It is important to recognize that, although these students are "all grown up", some of them may still need help in accessing the content. Regardless of whether they are dealing with a physical difficulty or have a learning disability, they have the equal right to an education. As educators, we need to find ways to address these needs so they can have the same opportunities as their classmates who do not have special needs.
