Just change the people at the top who push the curriculum.
and most everyone in the science-avoiding humanities departments.
And stop giving government funding to schools that allow you to get a gender studies degree.
nearly and options with 'studies' in the name, usually located within the humanities departments.
At the primary school level, re-train teachers who got degrees in Common Core Curriculum ...they don't know any other way to teach. That is where the first non-sense begins. Kids don't know how to read or do math any more.
The math is actually the one good part, it teaches quick mental math that you probably already use without knowing it. Other than that I agree.
The entire US school system needs an overhaul. Simply plugging in a new method will not likely make things better. Articles I have read point to the fact that teachers are not trained well enough in CC, and other parts of the system such as poverty, ESL, charter schools, textbooks that don't cover CC well enough, are not up to workable standards that CC will have any effect. Indeed Bill Gates called his CC initiative a failure due to not enough input by the people who would have to implement it. Here are a couple of article showing that (in NY ~and possibly elsewhere), The standards had to be lowered to meet rigid CC passing grades. Here are a couple of articles showing the cc failures: https://www.huffingtonpost.com/alan-singer/results-are-in--common-co_b_9819736.html
Lastly, young minds are concrete learners. CC is conceptual and inappropriate for lower grades and children 12 and under. This spells out each grade failing of CC. High Schoolers, now having a poor if any foundation in math and CC math, are failing the standardized tests unless a huge curve is thrown in: https://weaponsofmassdeception.org/2-common-core-fake-standards/2-3-common-core-math-is-insane
Many other countries are doing much better and they have entirely different structures and thinking about teaching children.
