This study examined the factors that may promote student-teachers' satisfaction with online collaborative learning (OCL). Eighty-four student teachers at the graduate level at three teacher-education colleges in Israel simultaneously completed questionnaires that examined their information and communication technology (ICT) skills, collaboration experience and personality traits. The findings reveal that ICT level, positive experiences with collaborative learning and openness contributed significantly to satisfaction with the collaborative project and accounted for 63% of the variance. Personal traits were found to be mediated by ICT level, and ICT level was in turn mediated by collaborative experience. The results demonstrate the importance of ICT level as a prerequisite for these courses and the significance of preparing the groups and structuring the activities to achieve positive collaborative experiences.
