The Effect of Problem-Based Learning Model on Efforts to Improve Critical Thinking Abilities of Nursing Students of Jayapura Health Polytechnic Papua

Critical thinking skills are essential competencies that nursing students must possess to navigate the complexities of clinical practice. The problem-based learning (PBL) model is believed to foster the development of these skills through an active, collaborative, and contextual approach. This study aimed to determine the effect of implementing PBL on the critical thinking skills of nursing students at the Jayapura-Papua Health Polytechnic. The research method used was quantitative with a pretest-posttest control group design. The sample consisted of 60 students divided into two groups: an experimental group (participating in PBL learning) and a control group (participating in conventional learning). The instruments used included a critical thinking questionnaire and an observation sheet. Data analysis was performed using paired t-tests and independent t-tests. The results showed a significant increase in critical thinking skills in the experimental group compared to the control group (p < 0.05). PBL proved effective in improving critical thinking indicators such as analysis, evaluation, inference, and reflection. It can be concluded that the problem-based learning model has a positive influence on the development of critical thinking skills in nursing students at the Jayapura-Papua Health Polytechnic. It is recommended that nursing educational institutions integrate PBL more broadly into their curricula.
