New research at York University in Canada both confirms and extends the concerns of many faculty members about laptop use in class. The research found that undergraduates who multitask on laptops comprehend less of what has been covered in a lecture than do other students. That part is unlikely to surprise most professors. But the study also examined students who were taking notes -- with some students sitting next to those who were multitasking on their laptops. Those next to a laptop multitasker also saw drops in what they picked up from the lecture. The findings have been published in the journal Computers & Education.
