Three Weeks of Team-Based Leaning Do Not Overload Undergraduate Students

Team-based learning (TBL) is a flipped-classroom approach requiring students to study before class. Fully flipped curricula usually have fewer in-class hours. However, for practical reasons, several programs implement a few weeks of TBL without adjusting the semester timetable. Students fear that they will be overloaded by the individual and collaborative study hours needed to prepare for TBL.

We implemented three consecutive weeks of TBL in a 15-week lecture-based course on the renal system. In-class time and assessments were unchanged for all courses. Four hundred fifty-nine first-year undergraduate medical students (229 in 2018; 230 in 2019) were invited to complete weekly logs of their individual and collaborative study hours during lectures and TBL, along with questionnaires on cognitive load and perception of the course. Our program changed from A to E grading in 2018 to pass-fail grading in 2019.

Participants (n = 324) spent a similar number of hours studying for TBL vs. lectures with a mean of 3.1 h/week. Collaborative study was minimal outside class (median 0.1 h/week). Results remained similar with pass-fail grading. If in-class time were reduced, 18% of participants said they would have used freed-up time to study for TBL. Studying for TBL generated similar extraneous cognitive load and lower intrinsic load compared to studying for lectures; students were less stressed, and maintained high levels of motivation and self-perceived learning.

Three weeks of lectures were replaced by TBL without reducing in-class time. Students did not report overload in study hours or in cognitive load.
