Enhancing Physics Problem-Solving Skills on Waves through Problem-Based Learning (PBL) Integrated with the Inquiry Method and Polya's Problem-Solving Techniques for Grade 11 Students at Buakhao School
Main Article Content
Abstract
This study investigates the effectiveness of using the Problem-Based Learning (PBL) management process combined with Polya's problem-solving techniques in enhancing students' physics problem-solving abilities and their satisfaction with the learning method. The research aims to (1) assess the students' ability to solve physics problems after engaging in PBL, with the goal of meeting the 70% performance criterion, and (2) evaluate student satisfaction with the learning approach. The sample group consisted of 33 students grade 11 from Buakhao School during the first semester of the academic year 2024. The research tools included six learning management plans, a multiple-choice test with four sets of ten questions each, and a satisfaction questionnaire with 20 items. Data analysis was performed using mean, standard deviation, and t-tests (one sample). The results showed that (1) students' physics problem-solving abilities significantly improved after the PBL-based instruction with Polya’s techniques, surpassing the 70% criterion, with statistical significance at the 0.05 level, and (2) student satisfaction with the PBL approach was at a high level (Mean = 4.63, SD = 0.70).
