Hi Harry, You're right, research is very important. I also have privately and appropriately asked a physically disabled student how best I can work with them without drawing undue attention to the situation and without positioning it as just an accomodation. For learning disabilities, it is more of a step-by-step process in discovering the best way for a student to master a concept or application. In many circumstances, the learning disability was never diagnosed or addressed, and studnets with the same type of learning disability, still react and assimilate information in different ways. Thanks, Jay ED106
