I subbed for a honors history class (aimed for AP tests) that mostly enrolls sophomores, but has a few seniors in it. The sophs are pretty motivated and gung-ho, but the seniors just weren't very motivated and didn't want to do the classwork. One of them pretty much admitted as a 2nd semester senior, after 3 1/2 years of working hard, he wasn't very motivated to put out. I did advise him that if he really let it go - he would 1) risk failing the class, then 2) not get his diploma AND 3) any college that accepted him could pull their acceptance if he did not get the diploma. I thought that was a poor example to set for the sophomores - not to mention that it interfered with classroom management. I told the regular teacher about it and he was not happy at all - said he would talk to the students' parents. What are some things/tasks that you do to combat senioritis?
