The title says it all. This posting lists Facebook applications that are particularly relevant for students, teachers and administrators, and everyone.
“before sending students off on work placements, ask someone at the workplace (a mechanic, a florist, etc) to Twitter regularly throughout the day. This gives the learner some idea of what someone in that job role has to do throughout a day, and it gives them the opportunitiy to ask some questions. When the learner goes on work placement, they could use Twitter to log their tasks and thoughts.”
