This study investigated the performance of 13 graduate students' collaborative efforts toward a group research project in an Instructional Analysis, Design, and Evaluation online course. Gaps between course expectations from the instructor and student collaborative performance were identified through the review of the team agreement, the use of surveys, and focus group interviews. Performance gaps occurred in the areas of communication, assignment completion, and group cohesiveness. These performance gaps were caused by lack of knowledge and skills, motivation, and/or organizational support. Appropriate intervention strategies such as effective group interaction and communication, building relationships and establishing trust, periodic review of team agreements, mini-training sessions on collaboration and supportive behaviors, and role differentiations and collaborative task designation are presented. Instructors who are interested in incorporating group research projects into their future online courses may consider implementing these interventions to facilitate the improvement of students' collaborative efforts.
