I had one student who would always be trying to read paperbacks in class. His excuse was Aspergers syndrom and this was how he learned. I explained that in the field he chose, he would be attending meetings where his focus needed to be on the meeting and not on a paperback text. Especially since some of his meetings might also include clients or family members. Reading a paperback could be viewed as being very non-committed to the client or uninvolved with the care of the client, just to name one problem it could cause. We decided together that he would need to be able to listen in a meeting and that he would practice this in class and we wrote up a contract that covered his behavior not only in my class, but in all classes he was attending. His behavior improved dramatically, but not without some setbacks, but we all (all of his instructors) enforced his contract and reinforced the student. He did sucessfyully complete his course of study and graduate.
