It was the phones that tipped off Bo Ruberg.Ruberg, a UC Irvine assistant professor in the department of informatics, was teaching “Games & Society.” It was November 2017, and the course was a required class taught to 260 students, the majority of which are typically male freshmen. Ruberg kept a strict no-screens policy in their classes — an easy enough ask to keep students from texting or scrolling through Instagram when they should be paying attention. But this was different: a dozen or so people holding up their phones, recording their lecture on gender without even the effort of hiding it. The class felt strangely fuller. Ruberg paused, reminded students of the policy, and assumed they would put them away. They kept their cameras trained on Ruberg.
