Why not hire more “Jaime Escalantes” in the school system to encourage the students to make math FUN again? There are ways to make math fun and competitive without dumbing it down.
Hire some people of color who are damned good at math to teach these kids!
When my daughter was young one of the better math teachers she had was a black lady. This teacher lady was very smart, and her children (she had a lot of children) went on to become get good educations and become employed as professional people.
I worked with a black guy who was very good in math and was good at visualizing abstractly. He got his masters in engineering degree while he was working. He did not have good English skills and struggled with writing, however.
It is just not true that black people cannot be really good in math. It is the culture and family structure that is holding them back.
