This is going to be difficult. Math ability is largely genetic, as are the abilities to focus on a problem or to hold one number off to the side while you do a second calculation.

For this reason, the kids that are not that good at math can only be taught by drill and repetition. Insight is useless. But education schools are determined that drill is bad, and literally anything else must be used to teach all subjects, including math.

Also, there is no evidence that inspirational or motivational tactics are any good in most subjects, and have even been found to be an additional problem (because they are a distraction, increase anxiety, and increase guilty feelings) in math and science.

Lastly, the type of math that males, including black males, are better at is spatial, which is the weakest category of math for the women who are teaching school. They therefore do not even pick up who might have an interesting ability that could be turned into something useful because they don't even recognise it themselves.

So to fix this the schools will have to admit that
1) the races are On AVERAGE not equal in mathematical ability
2) their preferred method of teaching does not work and the thing they dislike most does work
3) their main fallback of being encouraging can make things worse as often as it makes them better, depending on the "encouragement," and
4) not only classroom teachers but the faculty and research arms of the ed schools will have to be taught the rudiments of spatial knowledge and be trained to look for it.

How likely is this?
