> individual learning differences can function to intensify and amplify the underlying economic and racial inequities in education. If a bright child from an affluent family doesn’t learn well in a traditional classroom –– and make no mistake, many don’t –– his parents have the option to place him in a private alternative educational setting (including homeschooling or unschooling) where he may be able to thrive. If a bright child from a low-income family has the exact same problem, he has nowhere to go. The system will treat him as though he has lower intelligence and academic aptitude; after years of this he may come to believe that he is less intelligent, and/or the frustration, shame, and stigma that he experiences may be channelled into discipline problems at school.
