Has anyone experienced with a student that even though you lecture and do hands on activities on the subject at hand, they still have trouble getting it? Whats some work arounds that?

Out of all the Disabilities that are out there, can you ellaborate on what you believe is the most complex our difficult to understand?

As much as I agree that visual and hearing are huge in the learning process, Being able to do hands on (feel) is a very helpful tool in having the student learn. Working in the field of audio I have noticed that as the students learn the theory and are able to visually see presentations and video's of how things are done, actually being Hands on and doing it themselves helps tremendously in the learning process.
