A Study on Problem-Based Learning and Its Effects on Mathematical Resilience and Learning Achievement in Elementary Geometry Among 46th Generation Students at Phra Dabos School

This research studied mathematical resilience and learning achievement in elementary geometry among 76 students in the 46th generation of Phra Dabos School after problem-based learning activities. Research tools included five problem-based learning plans, questionnaires on mathematical resilience, and achievement tests in elementary geometry. Data analysis utilized percentage, mean, and standard deviation. Findings showed that 1) After the intervention, all students showed enhanced mathematical resilience. Moreover, at least 61.84% improved their mathematical resilience to high levels. 2) 62.90 percent of students scored higher on elementary geometry concepts on a post-intervention learning achievement test.
