Ambikairajah , Epps, Sheng, & Celler (2008) found that lecture captures increased active learning for engineering students, especially those within large classrooms. They discovered that delivering lectures solely through the use of pre-recorded lecture material allowed in-class time to be spent on focused, critical discussions. Day and Foley (2006) conducted a quasi-experimental study with students studying HCI (human-computer interaction). They found that the final grades of students who used pre-recorded lecture captures were significantly better than those in the traditional lecture classes
