Hi Joan,
I just had a meeting with the graduate admissions program at my University, and something they told me is: you can't dabble in graduate school. I guess this doesn't help you so much since you're already immersed in a program, but you may want to explore the different options within your area of study right now. Talk to professors and professionals to see if there's a world outside of teaching which may be an option (like one-on-one teaching, or consulting.) Are there other areas of Art Education which you haven't experienced? If so, do an internship or look into whether it might interest you. If not, why bother continuing the program if you're sure it's not for you?
I've just stopped my current path after determining it wasn't for me, and am committed to trying other options out as best I can to see if I like them. When I find a better fit, I can go back to school if I need to at that point. But, speaking from experience, there's no point continuing something you know you're not passionate about just because you've already started the path...in the end you'll either be unhappy or end up switching anyway and will have spent more time and money in the process.
Hope this helps.
Kate
