Form of blended learning in which students learn content outside the classroom, e.g., by watching video lectures or tutorials. Instructional content is often delivered online. Afterwards, students and teacher meet in the classroom to discuss the instructions, apply the knowledge, and do excercises.
Folksonomy (folk+taxonomy), also known as social tagging, is a user-defined metadata collection. A folksonomy evolves when many users create or store text at particular sites, such as wikis, and identify via tags what they think the text is about. Folksonomies differ from taxonomies: Folksonomies structure content via user tags; taxonomies are classifications defined by more formal methods that do not necessarily include user-generated tags.
