The Virtual Classroom refers to the online classroom delivery tool within a Virtual Learning Environment. A Virtual Classroom is part of the distance learning platform, which typically incorporates course materials, homework, tests, assessments, and other tools that are external to the classroom experience. Virtual Classrooms may also include social media tools that allow learners and instructors to interact via chat or online discussion boards. They often utilize Web 2.0 tools, and include a Content Management System. Virtual Classrooms are often integrated with an enterprise’s LMS/LCMS, or ERP system. Virtual Classrooms are most often part of synchronously delivered programs, but may also be incorporated into asynchronous learning programs.
