This article describes the development and evaluation of STARstreams, a pilot effort to utilize videos and online discussions in a conflict resolution curriculum that acknowledges the inherent socio-personal aspects of conflict. The STARstreams curricula includes a set of video-based scenarios depicting conflict situations and potential resolutions to those conflicts, a web-based conferencing system for cross-classroom discussion of the scenarios, and a handbook to guide teacher implementation of the curriculum. These materials were evaluated in a 2-week field trial with four geographically diverse 5th and 6th grade classrooms. The experimental STARstreams curriculum was well-received by participating students and teachers, engendered extensive participation in online discussions about the scenarios, and had a statistically significant effect on measures of social problem solving, self-efficacy toward conflict resolution, and perceived value and satisfaction with the materials. The overall program and its development are described; classroom experiences, online discussion, and quantitative outcome measures are presented; and implications for future efforts are discussed.
