Abstract

This study investigated the efficacy of Problem-Based Learning (PBL) in enhancing students' problem-solving abilities in physics education, addressing the lack of effective methodologies in nurturing this crucial skill. Utilizing a quasi-experimental design, 58 secondary school students from Nigeria were divided into an experimental group, which received PBL instruction, and a control group, which received traditional teaching methods. Over three months, both groups were assessed using an essay test format before and after the intervention, focusing on problem-solving abilities related to force and motion concepts. Descriptive and inferential statistical analyses were employed to evaluate the pretest, posttest, and n-gain scores, revealing significant improvements in problem-solving abilities within the experimental group compared to the control group. Specifically, students exposed to the PBL model exhibited higher average scores and greater improvement in problem-solving skills across various indicators, including understanding the problem, developing a plan, implementing the plan, and reflecting on solutions. The findings underscored the effectiveness of the PBL model in fostering active engagement, collaborative learning, and structured problem-solving processes, aligning with contemporary educational approaches that prioritize practical skill development and critical thinking. This study contributed to the growing body of literature supporting the efficacy of PBL in enhancing problem-solving abilities, highlighting its potential to cultivate a dynamic learning environment conducive to the development of essential skills in physics education.

Abstract

This study investigates the impact of integrating ethnoscience with problem-based learning (PBL) on the enhancement of critical thinking skills among secondary school students. Employing a nonequivalent control group design with purposive sampling, the research involved 66 students from a Nigerian secondary school, divided into experimental (n=31) and control (n=35) groups. The experimental group engaged in a PBL curriculum enriched with ethnoscience, while the control group received traditional expository teaching. The study aimed to bridge the gap in current educational practices by incorporating cultural relevance into science education, thus making learning more meaningful and directly applicable to students' lives. Results indicated a significant improvement in the critical thinking abilities of the experimental group, as evidenced by their pretest and posttest scores, compared to the control group. The findings underscore the effectiveness of the ethnoscience-integrated PBL approach in fostering higher-order thinking skills, suggesting a notable advancement over conventional teaching methods. This research contributes to the educational literature by demonstrating the benefits of combining ethnoscience and PBL, advocating for a shift towards more dynamic, student-centered, and culturally relevant teaching strategies. The study highlights the importance of contextual learning experiences and suggests further exploration across various disciplines and educational levels to validate the approach's effectiveness and applicability.
