I’m glad that my colleague Jay Greene believes that the school-reform movement should be advocating both good instructional practices and improvement through competition. And I intend to keep writing about the moral imperative of school-choice programs for poor children stuck in failing inner city public schools, just as I did in my City Journal article. I look forward in turn to his support in the future for scientifically tested instructional programs like Direct Instruction, Success for All, Singapore Math, and Core Knowledge.
