The investigators have planned a randomized study, examining the effect of self-directed
training in groups vs. individual training on trainees' acquisitions of open surgical skills.
Eighty participants who signed up for a pre-existing simulation-based course in basic open
surgical skills will be randomized to practice either in pairs or individually during the
course. Participants open surgical skills will be tested on a simulated skin model before and
after the course. The investigators hypothesis is that dyad training will enhance
self-directed learning in open surgical skills.
