The document summarizes a study that used Kirkpatrick's four-level evaluation model to examine the effectiveness of collaborative online group work. The study compared outcomes for students who completed a course through real-time learning versus online. Results showed that while real-time students reported higher satisfaction in some aspects, the online model successfully supported group learning behaviors and improvements. Reaction levels assessed satisfaction and understanding of group work, finding both cohorts highly satisfied. Evaluation levels found online peer-assessment provided translational learning. Behavior levels showed students benefited from observing group behaviors of others.
