I agree with rowuk... however, as a private instructer for a local high school, I understand your delimma... the key is time management... I will share with you how I go about my 30 minute block... I have two hours to teach 5 students twice a week, so I understand time constraints!! ;)

I think everyone here would probably agree that the warm up is one of, if not THE, most important part.... you should already be warm before the lesson, that way you don't waste any of the students time... then spend the first ten minutes helpind the student warm up... play some long tones and warm up exercises with them, but spend most of the time just listening and helping them, only play when you think they need to hear it. Then spend a couple of minutes explaining the next exercise... I usually go into some technical exercises that incorporate tonguing and fingering... the few minutes you spend explaing gives the students chops a rest, then play the exercise for them and let them play it back to you... at this point you should have eaten up a good 20-23 min. I like to spend the last few minutes doing something fun, a good duet book is a great way to end your lesson, pick something smooth and low and you can use this as the cool down too... It might not be the ideal situation for practice... but it is better than nothing at all!!
