1) The study examined factors that promoted and hindered collaborative learning for students in a virtual course. Factors related to positive group processes and structure were most influential. Environmental factors also impacted collaboration.
2) Promoting factors related to interaction and group structure decreased over time, while factors linked to student activity increased. Hindering factors shifted from group heterogeneity to passive group members.
3) Understanding student perspectives on collaborative learning is important for improving course design and support to enhance learning outcomes. Positive group dynamics must be supported, while individual accountability also impacts the collaborative experience.
