The Randomise Trial

Joshua Bellini says natural experiments are valuable for understanding the world. He explains how a study of allowing people to use electronics in the classroom led him to believe he was right about its negative effects. But it turns out that there's a big negative effect on learning from using electronic devices, which is why i forbidding them has been vindicated by this trial.Bellini: "I'm thinking aboutt the way i teach it. I've always forbidden electronics"
