It is interesting how accommodations can reveal dysfunctions in educational practice. In my courses, requests for accommodations generally change the course design for all students. This is because the accommodation does not alter expected learning outcomes, but it is clearly something that aids students with difficulty learning the material succeed. My goal is that all students succeed in the expected learning outcomes. I don't want the course to be challenging for the wrong reasons. So often the request reveals something I was doing that is unnecessary and makes the class more difficult for little reason. That isn't to say that there are not learning environment that should add additional stress. Sometimes such conditioning is needed so that one can succeed in the challenges they are being trained for. That isn't the case for my students.
