"Our results also have implications for student support in online classes," they write. "Faculty members teaching online should be aware of the performance penalty associated with taking courses online and consider implementing course policies and practices that would allow them to detect student disengagement in the absence of the physical cues that FtF [face-to-face] instructors can rely on. Students should be made aware that success rates are systematically lower in online than in FtF sections so that they can make informed enrollment decisions, and should be introduced to study strategies and time management strategies that promote success in online formats."
