Angelina,... not a technique, just an observation you seem unaware of the anger (or fear) within your comments. I don't agree wholly with your view, but do agree partly with it. I appreciate the burden you feel for parents wanting their children to have a sound education.
Unfortunately, I think the reality of 'politics' is inexorably tethered to public-education, since government funding, agencies, and legislation are involved.
There's not a simple solution to this complex government-bureaucracy knot. However , Home-schooling is probably the best work-around at present. And the way that movement is growing is forcing government-schools to adjust,.. or simply go out of business.
And just as you are unaware of the inevitable 'politics',.. there's a huge insurgency of cultural Marxism undermining sound-curriculums? I agree that the core sciences are being undermined and neglected in favor of nonsense social-engineering in DEI-CRT (Diversity-Equity-Inclusion.. Critical-Race-Theory).. along with another 'Grand Deceit',... the theory of Man-Made-Climate-Change,.. which also is a 'political' faux-science deceit promoted by Statist-Socialist-Marxists.
This is not accidental, but intentional 'political indoctrination' into destructive demoralizing of America's (and the West) societies. And it's those who adhere to Socialist---or Statist-Communist-Fascist-Marxist-Islamist ,.. political ideas... who are adamant about indoctrinating American kids into those false beliefs.
