If you're reading The Miracle Worker about Helen Keller, you've got a few options to try to get the kids to understand the character's perspective. One is to tell them it's tough. One is to force them to experience it, like wearing a blindfold for a day. The one I chose was for the kids to use their imaginations in common situations.
Students get the choice of which disability. Some will choose something from which a family member suffers. They imagine a day and then analyze it from their own perspective. Finally, they are asked about accommodations. Yes, kids have big hearts, but they also have to understand the role of government in helping those who need help, which makes this a good assignment in a government-type class, too. And you don't have to be responsible for your blindfolded students crossing busy streets.
