I think the key to interest in a VLE is getting the pupils excited and using it. At Abbots Hall Primary school each class has a blog where pupils can share things a la Facebook. They also have their own pages to talk about themselves. Another good feature is the Quiz. The teacher can easily set up a simple quiz with multiple choice questions. The pupils enjoy going on at home to complete it. the teacher can see the reults and send them back a message congratulating them. It's going really well.
