The coronavirus disease (COVID-19) is a public health emergency of international concern. The spread of the virus all over the world sent billions of people into lockdown. In light of rising concerns, a growing number of universities across the globe and specifically in the United States have either postponed or canceled all campus events such as workshops, conferences, sports, and other activities. Universities took intensive measures to prevent and protect all students, faculty, and staff members from the highly infectious disease. This resulted in migrating all face-to-face courses into an online course. In this paper, the authors present the impact of COVID19 on migrating a Team-based Learning C programming course from face-to-face to online delivery and its effect on student learning. The results section of this paper shows that the student learning curve was affected significantly by the sudden online delivery of the course.
