Faculty and administrators across the country, shaped by their experience adapting instruction during the COVID-19 pandemic, knew what to do last week. Shifting the modality of instruction is not new for us. Instructors quickly improvised alternative assignments, delayed quizzes and exams, populated offline course materials, and adjusted timelines in order to keep learning moving forward. When it came time to notify students of these adjustments, however, a more fundamental issue became apparent. Many instructors came to discover they had no reliable way to contact their students outside the learning management system itself. Some did not know how to access their course rosters outside Canvas. Others teaching large online lectures encountered institutional email delivery limits. Many had no established communication pathways beyond LMS announcements.
