One possible method is to not release marks on the VLE until the students have collected their coursework from the seminar/workshop. The lecturer would take a marks list to the workshop and return the coursework without a mark. The students are then given some time to try and work out their mark from the feedback. They could also be encouraged to compare the feedback on their work with that of their peers in order to help them with the process. A grade incentive could also be used to encourage the students to take the activity seriously. For example they could be awarded the higher of the two marks if they self-assessed within 5% of the lecturer’s assessment.
