Well, I guess I come pretty close to fitting the description of your students (only been playing about six months) so if you want that point of view, this is what I'd want if I was enrolled.

1. Just like everybody is saying, some songs that are learnable in an afternoon's practice between sessions and that are familiar and fun.

2. A good chunk of time on posture and positions. Both right and left hand positioning, and body posture while playing. That would have saved me a fair amount of frustration and pain over the past few months.

3. Basic arpeggios and rolls along with easy songs (Parsley Rosemary Sage and Thyme is an easy arpeggio, and Goodnight Irene sounds pretty OK with a basic inside roll)

4. A little boom-chick and boom-chicka stuff. Sounds cool and makes me feel like I know how to play (oh how easily simple minds are decieved....).

Anyhow, I don't know if that is at all useful, since I am a novice and don't know what the heck I'm talking about, but I'd think that'd be fun.
