Emergency Remote Teaching and Online Exams at the National and Kapodistrian University of Athens during the COVID-19 Pandemic

The outbreak of COVID-19 pandemic has caused a great disruption in higher education worldwide. Traditional face to face teaching had to change suddenly and in an unplanned way in emergency remote teaching, a temporary shift of instructional delivery to an alternate delivery mode due to crisis circumstances. This paper presents the transition to emergency remote teaching at the National and Kapodistrian University of Athens (NKUA) during the COVID-19 pandemic and explores the challenges and the opportunities in several aspects, technological, pedagogical, organizational, individual and social, based on lessons learned.
