PeerMark appeared in the January roll out of a major Turnitin update in January 2010. For a change, this new feature works within the Blackboard integration, so I’ve been taking a look at it. Here is a quick video demonstrating one of the assignments I set up.
If you want to do anonymous or open peer marking with students, this is certainly a good way to do it. It was used on the Bioinformatics MSc last week, which has been written up as a separate case study.
I have some usability issues with the system – it is difficult to preview the assignment to know how exactly it will appear to students. Getting the dates for submission and posting sorted out can be challenging, there are a lot of dependent dates involved and again it isn’t intuitive to know what dates to pick. Overall if you want to do peer marking on work that can be submitted through Turnitin, this is a good option.
