The typical education experience for a Black boy in the United States, is to have almost all white teachers, mostly women, more than half of whom vote for the most racist candidate on any ballot, and no Black teachers. The teachers have low expectations of you, punish you more than your classmates, and threaten to call the cop who works in the hallway on you at any moment.
I don't know how to explain more clearly, that this is never going to work.
I'm not surprised that Black US kids don't perform as well as white US kids, or as well as Nigerian, Ghanaian, Kenyan, or Caribbean kids. I'm surprised that any Black kids make it through this hellish gauntlet at all.
When you look at how much the US pays to educate each student, and how poorly it does at Black educational achievement, it's clear that the US is the worst country in the world at educating Black students, by far. Because racism. No one spends more to achieve less.
