Opening the black box of team-based learning (TBL): A study of verbal interactions in online application sessions.

CONTEXT: In team-based learning (TBL), an instructional strategy that encourages in-depth team discussion and deep learning, interactions in terms of sharing, co-construction, constructive conflict and procedural interactions are important. Since TBL has also been applied online in recent years, the question is whether these interactions are sufficiently present in an online setting. AIM: Gain insight into the nature and extent of these types of interactions in online TBL application sessions and to what extent these vary between teams and sessions. METHODS: We made audiovisual recordings of 12 TBL teams in two online application sessions during assignments. Transcripts were coded and analyzed using a framework derived. RESULTS: Teams spent more than 85% of their time on all four types of interactions in both sessions. The largest proportion of time was spent on sharing and co-construction. Constructive conflict occurred to a limited extent. We observed variation in proportion of time spent on and the distribution of the four types of interactions between teams and sessions. DISCUSSION: All interactions important for achieving deep learning occurred in online TBL application sessions. However, the effective use of these types of interaction should not be left to chance.

Team-based learning (TBL): Each phase matters! An empirical study to explore the importance of each phase of TBL.

CONTEXT: In Team Based Learning (TBL), it is, based on theory, assumed that knowledge development in each phase contributes to the subsequent phase and to learning performance. However, there is no empirical evidence for this assumption. AIM: In order to find support for the relation between TBL and the underlying theory, we determined to what extent each phase of TBL is associated with the knowledge development in the next phase and with the total learning performance. METHODS: We measured the scientific concepts recalled by 56 second-year undergraduate medical students before TBL, after each of the three phases and after TBL. We used multivariate regression analysis to determine the statistical association between the phases as well as the total learning performance. RESULTS: Results showed that in each phase, students produced new concepts in addition to those previously recalled. Regression models showed statistically significant explained variance ranging from 0.19 to 0.26, between the three phases and the total learning performance. DISCUSSION: Each phase of the TBL is significantly associated with knowledge development in the subsequent phase and with the total learning performance, and therefore matters. This study contributes to the scientific underpinning of TBL and offers leads to more elaborate research and interventions to improve TBL.
