But a growing body of evidence shows that over all, college students learn less when they use computers or tablets during lectures. They also tend to earn worse grades. The research is unequivocal: Laptops distract from learning, both for users and for those around them. It’s not much of a leap to expect that electronics also undermine learning in high school classrooms or that they hurt productivity in meetings in all kinds of workplaces...Can't pass up a shout-out to my alma mater!
The researchers hypothesized that, because students can type faster than they can write, the lecturer’s words flowed right to the students’ typing fingers without stopping in their brains for substantive processing. Students writing by hand had to process and condense the spoken material simply to enable their pens to keep up with the lecture. Indeed, the notes of the laptop users more closely resembled transcripts than lecture summaries. The handwritten versions were more succinct but included the salient issues discussed in the lecture...
At the United States Military Academy, a team of professors studied laptop use in an introductory economics class. The course was taught in small sections, which the researchers randomly assigned to one of three conditions: electronics allowed, electronics banned and tablets allowed but only if laid flat on desks, where professors could monitor their use. By the end of the semester, students in the classrooms with laptops or tablets had performed substantially worse than those in the sections where electronics were banned.
Anyway, go read the whole thing.
