Answer:
to ensure all schools learn about black history it needs to be integrated within the normal consensus and curriculum as history instead of being segregated as another subject entirely.
It needs to be compulsory to learn about it all year round instead of one month in the year as there is so much if not more history than we could ever learn in our lifetime let alone in a month.
in conclusion i believe to make sure all students learn about 'black' history is to stop segregating it to its own subject and just call it history. learn about all history together as one.
hope this help
