Create your own arguments in aMap and embed into a blog or a wiki. As you add to your argument you are guided by keyword starters. Once you have stated your position you are directed to a window where you have to add your name and email. This would probably be better for older students who have their own email addresses as everybody who adds to the argument are directed to put in their details. This is still a fairly new programme and they are still fixing bugs so it will be interesting to see how it develops. I have put in a recommendation for password protection to protect arguments that students are writing.
R rating: none that I could find
