This article provides an overview of the state of research on social media and education in the twenty-first century. We begin with a synthesis of recent literature reviews to provide context for the articles within this special issue of the American Journal of Education titled “#Cloud2Class: The Disruption and Reorganization of Access and Use of Educational Resources in the 21st Century.” Next, we introduce each of the four articles and two commentaries in the issue, highlighting their intersections. We conclude with a synthesis of three themes that run across the articles. Together, these articles illuminate the disruption and reorganization of education in the age of social media, forefront critical evaluation of social media’s challenges to education, and off-practical reflections on the future of education during an emergency, such as the global health crisis in 2020 posed by the novel coronavirus—COVID-19.
