Peer- and Self-rating of Open Surgery Skills

Participants will be given a print and a e-mail of the modified OSATS global rating scale and will be introduced to how the rating scale is used to rate technical performance. The participant will receive a USB stick each allowing the participant to see a video of his/her own performance and two videos from previous post-test performances from participants enrolled in the course. One video is a video of a participant who performed poorly,the other is from a participant who performed well. The participants will be asked to watch and rate the videos of their peers' performance first and afterwards watch and rate the participants own video performance. The investigators choose to let the participants rate their peers' performances before their own, so the participants will have the best opportunities to self-rate. Participants will be asked to email the results of their ratings to the principal investigator within 3 days. And expert in surgery will also rate the videos using OSATS.
