I have found that the attached version of the judging sheet works better than the one included with the pack. It is more straightforward and reduces the burden on “experts”.
For this version – one judging sheet per team can be used, experts can take notes on how well each team member does in the role they are supporting and fill in the “role” scores before lunch time.
Afternoon can be used to fill in other marks and students can assign poster marks e.g. each team chooses their favourite poster and writes on a post-it note, with no voting for your own team.
