: master's, or with another 2 years experience
: here in nowheresville?
First, it's best not to try to connect getting one with financial gain. It may or may not happen and any potential financial gain is marginal at best.
Second, Just about anyone can get 2 more years of experience. No big deal there.
Third, today's bachelor's degree is yesterday's high school diploma: everyone in our business of teaching has one. Another no big deal.
Fourth, getting a master's shows initiative in furthering one's education/professional development and once you get it, it's permanently on your record. It may or may not make you a better teacher, but it at the least shows a drive to further your education.
Fifth, taking a break from teaching this early in your career can indeed be a nice way to reset things. It's a great reason to get out of "nowheresville".
Sixth, having your two years of actual teaching "in the trenches" can give you a really nice change in perspective when going back to graduate school as I know it did for me when I did exactly that.
