The editors of the Washington Post state the case for the Common Core:
The Common Core is a set of objectives for student learning — not a mandated curriculum — that arose from governors, state education officials and others who understood that American children needed to raise their game to compete in the global economy. It is designed to move away from rote learning toward critical thinking and group effort. It assumes that parents will want to measure school and student progress. In many places, officials are saying that teachers should be evaluated in part on how well they are teaching, with good teachers being rewarded.
In this sentence they inadvertently make an argument for educational reform:
The critique about process is a straw man for the main objection: use of test results as a factor in evaluating teacher effectiveness.
I do not believe they mean “straw man”, i.e. an argument (usually that of your opponent) that you set up to be defeated easily. I think they mean “stalking horse”—a false pretext intended to conceal your true intentions.
