I have had superb results by giving capable students their own course. In fact, my computing class have their own course where they are all teachers. They are doing a moodle project for me. More soon .....
I note what you say about results but that falls under assessment rather than learning. I have no assignments or quizzes as such in the computing course. It's more of a sandbox for them to test their ideas and share. i made an initial post at sean k's site about the results but I think I will write them up properly at some point. Dunno where I would put them. Keep an eye on the teaching and learning forums if any one is interested in my revelations.
The problem with giving kids courses is, as pointed out somewhere before, they could enroll the whole school and
spam them. That, as far as i can see is the only downside. When the students get teacher access they see how everything can be monitored so they tend to play nice. Of course, there are certain students that should not be made teachers but that is a different thread ...
What do you mean by ' code that students can bring in in these not checked edit-fields?' please???
Ger, if you want to see the work my students have done by themselves drop me a moodle message and I'll give you a url and a password.
