Abstract

Purpose – Problem-solving is a key component in mathematics education, as emphasized by the NCTM. At SMAN 6 Kota Bengkulu, students’ performance in trigonometry remains low due to weak problem-solving skills and limited engagement. This study investigates the effect of the Problem-Based Learning (PBL) model, supported by mathematical literacy worksheets, on students’ mathematical problem-solving abilities. Methodology – A quasi-experimental design was employed using the Nonequivalent Posttest-Only Control Group Design. The population consisted of all 10th-grade students at SMAN 6 Bengkulu. Two classes were selected: Class XJ as the experimental group, taught using the PBL model with literacy-based worksheets, and Class XI as the control group, taught using a Cooperative Learning model. Data were collected through a mathematical problem-solving test and analyzed using an independent t-test. Findings – Results showed a significant difference in performance, with t<sub>value</sub> = 3.713 > t<sub>critical</sub> = 1.673, indicating that the experimental group outperformed the control group in problem-solving ability. Novelty – This study offers a novel integration of PBL with mathematical literacy worksheets—an underexplored instructional approach in secondary trigonometry education. By combining content-specific literacy materials with a problem-based pedagogy, the study addresses a gap in research focused on enhancing higher-order thinking in mathematics. Significance – The findings provide empirical support for incorporating literacy-based, student-centered strategies in mathematics instruction. The study has implications for curriculum design aimed at improving problem-solving performance in similar educational contexts.

Abstract

Students face challenges in understanding the minimum competency assessment (AKM) mathematical literacy questions, as they struggle to interpret and solve the problems effectively. This difficulty stems from their low comprehension of the questions and limited problem-solving skills, particularly when confronted with questions differing from the examples provided by the teacher. This study investigates students’ abilities to solve AKM mathematical literacy questions using Polya’s problem-solving steps. The research is descriptive with a qualitative approach, involving a population of all Grade VIII students at SMP 21 Bengkulu City during the 2023/2024 academic year. The sample consisted of 30 students from class VIII.3 and 30 from class VIII.6. Data collection included test and non-test (interview) methods, utilizing AKM-based test instruments and Polya step-guided problem-solving tasks. Results indicated that 44 students (73.33%) demonstrated low ability, 11 students (18.33%) showed medium ability, and only 5 students (8.33%) exhibited high ability in solving AKM literacy questions. Overall, students’ problem-solving skills were categorized as low, with notable difficulties in planning, executing, and reviewing solutions to mathematical problems.
