To increase student participation in the learning process, active learning methods, including small group learning, have become increasingly popular in modern curricula. One kind of small group learning, team-based learning, is a relatively new instructional strategy in health care education. Team-based learning uses theoretically based and empirically grounded strategies for ensuring the effectiveness of small groups working independently in classes with high student-to-faculty ratios (e.g., up to 200:1), without losing the benefits of faculty-led small groups with lower ratios (e.g., 7:1). To explore the effectiveness of this learning pedagogy, we evaluated students' level of engagement and attitudes toward the value of teams. Findings demonstrated that team-based learning is an effective teaching strategy for large groups of students.
