Abstract:
This study explored the activities of trainees learning technical skills using an educational networking tool with and without expert facilitation. Medical students (participants) were video-recorded practicing suturing and knot tying techniques and the resulting videos were uploaded to an educational networking site. Participants were then divided into two groups (one group containing an expert facilitator while the other group did not) and encouraged to comment on the videos within their group. We monitored the number of logins and comments posted and all participants completed an exit survey. There were no differences between the activities the two groups (p = 0.387). We conclude that the presence of an expert within collaborative Internet environments in not necessary to promote interactivity amongst the learners.
