I ran that criticism by Greg Anrig, vice president of policy and programs at the Century Foundation and the author of “Beyond the Education Wars: Evidence That Collaboration Builds Effective Schools.” The research on successful schools and good teaching, he said, highlights the importance of relationships among the people in a school: administrators and teachers and students. “None of these studies identify technology as decisive.” Where technology makes a difference, it tends to do so in places with a strong organization dedicated to improving teaching and where students closely engage with teachers and one another. “A device that enhances such interactions is good,” Anrig said. “But kids focused on the device, isolated, cuts into that.”
