In one of the starkest examples of how far new Republicanism has moved away from the old Republican establishment, new Florida Gov. Ron DeSantis said Thursday he plans to “eliminate” the Common Core academic standards from Florida’s public schools. Considering that former Florida Republican Gov. Jeb Bush was a driving force behind the national Common Core movement, this is a remarkable development.

In effect, the death of Common Core is beginning in the same state where it was conceived, and with the same state party that conceived it.

The original idea behind the core, one Jeb Bush devoted himself to evangelizing, was that uniform national standards would provide a benchmark against which the schools in all states could measure themselves and lead states to focus on the best practices to meet those standards.

The core soon swept almost the entire country, with 45 states plus the District of Columbia adopting the standards. But many grassroots conservatives revolted from the start, saying the standards would lead to a stultifying national curriculum that would effectively trample on local control of education. Substantively, critics said the reading standards devalued classic literature and encouraged cultural values antithetical to tradition and decency; that the math standards encouraged complicated, newfangled approaches while discouraging teaching methodologies that had worked for centuries; and, among sundry other drawbacks, that it discouraged cursive writing even as science was showing conclusively that cursive aids juvenile brain development.

After nearly a decade of core implementation, student performance hasn’t improved. In fact, whereas math scores actually were rising rapidly in the decade before Common Core, they have flatlined, or even dropped a bit, since the core was introduced. Not just conservatives but centrists and progressives piled on to denigrate the core.

Indeed, the standards themselves were written so badly in places that they were nearly indecipherable. Consider this bit of inscrutability from the core’s official standards of mathematical practice:



Mathematically proficient students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize — to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents — and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved.



Good luck making sense of that.

DeSantis’ promised executive order is a good move. While proponents of the Core were well-intentioned, the core always was a bad idea. A great feature of American federalism is states and localities as “laboratories of democracy” where policies can be tested and either succeed or be discarded, rather than imposed from above. Local entities naturally compete to produce the best results; successes are copied, with no central direction needed. The Common Core upended this sensible approach. It is long past time for all states to learn from the core's failures and begin again to develop high and sensible standards of their own.
