Advocates of personalized learning say that the approach has been unfairly conflated with teacherless, online-only education. They invoke Dewey and Freire and Montessori as guiding lights and take pains to emphasize, in almost liturgical unison, that personalized learning is not about tech—and that “tech is just a tool.” But skeptics warn that underneath the language of “student-centered” pedagogy is a tech-intensive model that undermines communal values, accelerates privatization, and turns public schools into big-data siphons. – The New Yorker
