Schoology is a social networking service and virtual learning environment for K-12 schools and higher education institutions that allows users to create, manage, and share academic content. Also known as a learning management system (LMS) or course management system (CMS), the cloud-based platform provides tools needed to manage an online classroom.[1]

Visually and functionally similar to Facebook,[1] . . . the social media features facilitate collaboration among a class, a group, or a school.[2]
