A meta-analysis of the impact of the problem-based method of learning combined with mind mapping on nursing instruction.

Abstract

Nowadays, there are a variety of viewpoints on problem-based learning (PBL) and mind mapping teaching outcomes in nursing education, but there are not many thorough assessments that are pertinent. We performed a meta-analysis to evaluate the effect of the PBL method combined with mind mapping on nursing instruction. A systematic literature search up to July 2022 was performed, and 1765 related studies were evaluated. The chosen studies comprised 1473 nursing teaching participants as the trial's baseline, with 770 of them using the PBL model with mind mapping and 703 enrolled as controls. Odds ratio (OR) and mean difference (MD) with 95% confidence intervals (95% CIs) were calculated to assess the effect of the PBL method combined with mind mapping on nursing instructions using dichotomous and continuous methods with a random or fixed effect model. The study protocol was registered in PROSPERO (registration No. CRD 42022432130). The PBL model with mind mapping reached a significantly higher results of nursing knowledge test (MD: 7.29, 95% CI: 6.88-7.71, p < 0.001) and pediatric practice test (MD: 9.89, 95% CI: 9.04-10.74, p < 0.001), as well as higher students' ability of independent learning (OR: 3.49, 95% CI: 2.11-5.76, p < 0.001) compared to the controls in nursing teaching. The PBL model with mind mapping resulted in a significantly higher results of nursing knowledge test, pediatric practice test and students' ability of independent learning compared to controls in nursing teaching.
