Views on classroom tech study

A survey from the University of Waterloo found that 68% of faculty don't like students using phones during class and 32% disapprove of laptops, saying that noneducational use of technology distracts from their teaching. Students, however, felt it was their choice to use such technology in class, with some saying they expected professors to be entertaining enough to earn their attention.

Laptop use and student achievement study

Laptop use in the classroom may be a distraction for some students, according to a study from economists at West Point. Data show students with the highest ACT scores and grade point averages who used laptops in class scored lower than peers who did not have access to the technology. In contrast, there wasn’t much of a difference between students with low ACT scores — those who were allowed to use laptops did just as well as those who couldn’t.
