Basically, most scholars think multi-tasking is bad for learning, even to the point of banning people from taking notes (let alone having any electronic devices) in class. A small cadre, however, thinks that we should be leveraging our students’ “hyper-attentive” proclivities instead of trying to reroute them into “deep attention.” But the bottom line is that those who think they are good multi-taskers probably aren’t. They’re just getting a buzz from juggling all of these balls at the same time.
