Regardless of what you may have actually done in school, which option best fits your learning style?
One final "capstone" class
You can count student teaching under "internship," but otherwise you are being boxed into one of these narrow options. Choose wisely!
(also, if you have not heard the term "capstone" or your definition varies, just think of a regular class with a big paper at the end, shorter than a thesis but with a narrower set of guidelines)
