I don't think a degree in education really prepares someone for teaching, except in meeting legal requirements. I've read that Teach for America recruits with only a few weeks of training do at least as well as new teachers with education degrees. See for example https://www.teachforamerica.org/sites/default/files/what_the_research_says_oct2013.pdf , although the source is TFA .
