Harvard admitted last week that it installed hidden cameras without informing either students or teachers. The cameras were used to study in-class attendance.
Researchers with the university placed the cameras in response to complaints the university received about student attendance dropping throughout the semester.
The study was approved by a vice provost with the university.
Cameras were placed in 10 classrooms where they tracked 2,000 students with still images taken at set intervals. Student names were not revealed and the pictures were destroyed after the study was finished.
Still, students and teachers felt uncomfortable. "I wouldn't call it spying, but I don't think that it's a good thing," economics professor told The New York Times.
