Don't get a Masters in Education thinking it will help with being a check airman, sim instructor, or LCA (not called IPs in the airline world). The airlines will teach you how to teach THEIR way.
Also, in my new-hire class at my legacy very few if any had a masters. The few that I know with masters got it in the military just because it was free.
If you are currently flying at an airline, 135, or military I suggest joining the training department. That is MUCH better resume material than a masters. Safety, Pro Stands, HUPER, and CIRP committees are also great resume fodder.
