If you’re a parent, teacher, or student, you probably won’t be surprised by these statistics: In schools that permit cell phones, 71 percent of students text during class. In schools that ban cell phones entirely, the percentage is nearly as high: 58 percent. While we frequently hear teachers and parents complaining about these statistics, not all adults see these numbers as a bad thing. In fact, a small but growing number of educators are exploring how cell phones might be used to help students learn more and learn better.
