Virtual learning environment
From Researching Virtual Initiatives in Education
A Virtual learning environment (VLE) is a software system designed to support teaching and learning in an educational setting, as distinct from a Managed Learning Environment, (MLE) where the focus is on management. A VLE will normally work over the Internet and provide a collection of tools such as those for assessment (particularly of types that can be marked automatically, such as multiple choice), communication, uploading of content, return of students' work, peer assessment, administration of student groups, collecting and organizing student grades, questionnaires, tracking tools, etc. New features in these systems include wikis, blogs, RSS and 3D virtual learning spaces.
