New in paperback. Hardcover was published in 2020. A leader in educational technology separates truth from hype, explaining what tech can - and can't - do to transform our classrooms. Reich takes readers on a tour of MOOCs, autograders, computerized "intelligent tutors," and other educational technologies whose problems and paradoxes have bedeviled educators. Learning technologies - even those that are free to access - often provide the greatest benefit to affluent students and do little to combat growing inequality in education.
