Evaluation of jigsaw collaborative learning strategy on students' learning of clinical pharmacokinetics of special populations

Objectives

To evaluate the learning gain and students' perceptions towards Jigsaw collaborative learning in comparison with lectures in learning about pharmacokinetic changes in special populations.

Methods

Undergraduates learn about A-D-M-E of specific populations via Jigsaw collaborative learning and didactic lectures. Pre- and post-lesson quizzes were conducted to evaluate the effectiveness of the teaching method in terms of knowledge gain. Surveys comprising Likert scale statements and open-ended questions were conducted to elucidate students' perception towards the teaching methods.

Results

From a class of 192 students, 118 (62%) and 110 (57%) students completed the pre- and post-lecture quizzes, respectively, while 176 (92%) and 168 (88%) students completed the pre- and post-Home Group discussion of Jigsaw quizzes, respectively. There was an improvement of 22.2% and 14.3% in median percentage quiz scores for the lecture and Jigsaw method respectively. Most students agreed that they have learned (54–60%) and collaborated (78–89%) through the Jigsaw method and rated Jigsaw as useful for their learning (54%). Open-ended survey responses offered a mixed conclusion where the didactic lecture was perceived to be as, or more effective than the Jigsaw method.

Conclusion

Learning gains were observed through the Jigsaw collaborative learning method which relied solely on peer-teaching, despite students perceiving it to be not as effective as lecture. The method provided opportunities for active and peer-learning. Further studies are needed to evaluate the long-term effects of this teaching method.
