If you've seen the elementary ed major coursework, then you can understand how this happens.
I spent one term (out of a five-quarter sequence) in an elementary ed master's program. I seem to recall that I had four courses (plus field experiences): literacy, numeracy, sociology in the schools, and multicultural topics in education. So we spent half the time talking about social justice issues, and the other half on pedagogy. I didn't stick around for the other four terms, so I don't know what they would have gone on to.
