Add NYC too...they graduate illiterate highschoolers there.
BTW, IQ tests reflect language skills. Even completely visual ones reflect the ability of the person to form concepts, which can only be done with language and Im not talking about English vs Spanish or Chinese or any other real language. Any real language permits one to develop concepts.
But they have ceased to teach black children standard English, and lower income blacks are now communicating in a patois that makes them unable to communicate or understand basic concepts. Dont forget that Ebonics was a product of the fact that many slave states forbade the teaching of reading (or anything, including the BIble) to slaves. The communication form developed by these speakers of various non-Indo-European languages, some of them very primitive without even expressions for time, mixed with shouted one or two word commands i n English from ugly, brutal overseers, produced a communication form that lacks basic concepts, particularly abstract concepts. There is nothing wrong with black children that improving standard English language skills wont help. But its politically impossible to do this.
NYC was wonderful when I was a child and went through the school system there, and California had a great reputation - but it was the failure to teach standard English and demand that the kids learn it and express themselves in it that has brought us to this state.
It appears so.
It further appears the "Direct Instruction" method outranks every other teaching method in this regard but has been successfully resisted by the unions and the decision makers.
If the agenda is to flood the community with barely functional members/government dependent voters, it would appear the ed system is on track.
