Improvement in critical thinking dispositions of undergraduate nursing students through problem-based learning: a crossover-experimental study.

Critical thinking (CT) is important to nursing education and practice. Although there is evidence that active learning approaches, such as problem-based learning (PBL), are effective in developing CT dispositions, the findings are inconclusive. This study examines the effect of PBL on the development of CT dispositions in nursing students using a crossover-experimental study in a course offered to nursing students in China. All students were randomly assigned to two parallel groups, with one group receiving PBL and the other receiving lecture-based learning (LBL) as a control. The CT Dispositions Inventory-Chinese Version was administered before and after the semester-long course. Data were collected at three time points. No significant differences between groups were noted in overall and sub-scale scores at baseline; however, pronounced differences in overall posttest scores existed between the PBL and LBL groups. Thus, PBL learning significantly enhanced the CT dispositions of nursing students enrolled in Medical-Surgical Nursing II.
