WebPA is an online automated tool that facilitates peer moderated marking of group work. If you do group work with your students it enables them to rate each other’s performance on a range of grading criteria set by you.
We’ve been using it in Swansea for several years now and those that use it, like it. Student feedback is also very positive.
It is open source software and starting from the 2015/16 academic year it will be integrated into Blackboard.
You can get more information on the software from the project website: http://webpa.ac.uk/
