English research . . . just too broad an area!

I'm trying to think of something to do in English, maybe related to
- grammar instruction & Writing Test scores (may be unavailable for study now)
- feedback on writing & its effect on students' revision
- gender differences (teachers to students) . . . which might be trite
- classroom procedures for starting &/or ending class (effectiveness?)
- effect of teachers' use of modern music (audio, written lyrics, videos) to teach literature
- something related to students' opinion of English as a subject and the correlation with teacher attitude/posture

Anyone have suggestions??? I'm so lost! I would like to do something that I can learn from myself and carry into practice fall after next. I don't want to do something just for the sake of research, because as Dr. McCoy said, if I just "tolerate" a topic now, I'll HATE it by December!
