Reddit mentions of Social Studies, Literacy, and Social Justice in the Common Core Classroom: A Guide for Teachers

This is anecdotal, but recent, and applies to your question. My niece was recently checking my great-niece's homework. My great-niece is 11. One of the questions was, "What did Patrick Henry mean when he said 'Give me liberty or give me death." My great-niece had written, "He was just being dramatic."

My niece asked her, "Why did you answer the question that way?" My GN said, "Because that's what the teacher told us."

Then commenced a lesson on what he ACTUALLY meant when he said that.

But more towards your question:
