Now, Diane Sieber at Colorado University has given students another reason to put away computers: enlightened self-interest. She found those using computers in class did 11% worse on average than those who didn’t (my emphasis). (See also here.)
Last fall, Sieber had 96 students in one of her courses and she took note of which ones were frequently using their laptops. After the first test, she alerted the 17 students who used their laptops intensely that, on average, they performed 11 percent worse than their peers who weren’t glued to computer screens. The number of students on laptops eventually dwindled to a half dozen, and the test scores of students who stopped using their computers during class shot up, according to Sieber.
“These are grown-ups,” she said. “They need to identify what keeps them from learning, and then act on it because they aren’t going to have me for the rest of their lives telling them ‘No, no, no. Focus.’”
Now, how can I get them to put away their smart phones?
