A research project at Harvard University is causing a lot of controversy this morning. The school has acknowledged that it secretly photographed more than 2,000 students in 10 lecture halls as part of a study on classroom attendance. During a meeting Tuesday night, Peter K. Bol, Harvard’s vice provost for advances in learning, said that researchers in the Initiative for Learning and Teaching, which Bol oversees, installed the cameras last spring as a way to track attendance. The cameras would snap pictures of students and a computer would scan the images. The names of students whose images were taken have not been released but the revelation has a lot of people talking. What do you think? Did Harvard cross the line by installing secret cameras as a way to track student attendance?
