M.A is more research orientated program in most of the univs. (UIUC, Stanford, U of Mich ect..)
When it comes to TC, however, M.ed is the same as m.a in the others, and m.a in TC is actually the practical one.
You can easily find out by looking which course requires more credit hours and asks for thesis.
M.ed in TC requires 60 hours while m.a only 30.
