The Florida Department of Education says the new standards don’t teach that slavery was beneficial.
However, one of the benchmarks (SS.68.AA.2.3) states students will be taught, “how slaves developed skills which, in some instances, could be applied for their personal benefit.”
Either this is some very unfortunate phrasing for establishing that people like Phillis Wheatley are required material (and even then it was less ‘thanks to’ and more ‘in spite of’) or something more nefarious is afoot.
