The flipped classroom is being talked about on lots of web sites and blogs at the moment. This diagram gives a great overview of the concept.
This is fantastic for higher education but I am not so sure that it is the 'be all and end all' for education with younger children.
While I love certain aspects of this I am also concerned that children/students need to 'smell the roses' and 'get dirty'. We don't want them to have too much to do at home - they need to enjoy life as well.
