Collaborative teaching strategies such as peer instruction and conventional group work have previously been shown to enhance meaningful learning, but they have not previously been compared. In this present study, we compared the impact of solving quizzes with peer instruction and conventional group work on immediate learning in a laboratory exercise. A total of 186 second-year medical students were randomized to solve two quizzes by either a peer instruction strategy ( = 93) or conventional group work ( = 93) during a mandatory laboratory exercise on respiratory physiology, after which all students completed an individual test. There was no difference in total test scores between groups, but students randomized to peer instruction obtained the highest test scores in solving simple integrated questions. Conversely, students randomized to conventional group work provided the best evaluations of the overall assessment of the laboratory exercise. In conclusion, different collaborative teaching strategies implemented during a laboratory exercise appear to affect immediate learning and student satisfaction differently.

Peer instruction versus conventional group work-based teaching in a laboratory exercise on respiratory physiology: a randomized study.

What is the central question in this study? How reliable is the combined measurement of the pulmonary diffusing capacity to carbon monoxide and nitric oxide (D ) during exercise and in the resting supine position, respectively? What is the main finding and its importance? The D technique is reliable with a very low day-to-day variability both during exercise and in the resting supine position, and may thus provide a useful physiological outcome that reflects the alveolar-capillary reserve in humans.
