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

This study aims to develop a mathematics teaching module based on the APOS (Action, Process, Object, Schema) model integrated with GeoGebra, focusing on the topic of quadratic functions for tenth-grade students at SMAN 1 Muara Beliti. The research employed the Plomp development model, which consists of five phases: preliminary investigation, design, construction, validation, and limited testing. The module was developed under the cognitive stages of the APOS model: action, process, object, and schema, and was enhanced through visual exploration using GeoGebra. The research subjects consisted of tenth-grade students and a mathematics teacher at SMAN 1 Muara Beliti, selected through purposive sampling. Data were collected through documentation, expert validation sheets, and practicality questionnaires completed by the teacher and students. The findings indicate that the developed module is highly needed by students and significantly addresses their difficulties in understanding mathematical concepts. Expert validation yielded an average score of 87.85%, classified as highly valid. Practicality testing produced scores of 92.50% from the teacher and 90.41% from the students, both categorized as highly practical. Thus, the module facilitates interactive, conceptual, and contextual learning aligned with the principles of the Independent Curriculum. Accordingly, it is deemed a feasible and innovative instructional resource for high school mathematics learning.

Abstract

This study seeks to delineate the numeracy competencies of students in the geometry domain, framed by the cultural context of Bengkulu. Employing a qualitative descriptive approach, the research involved 35 students from Grade  XI. A of State High School 1 Bengkulu Tengah. The methodology included the use of open-ended numeracy tests specifically designed for geometry. Data analysis was conducted using descriptive statistics to delineate the spectrum of numeracy competency levels among the students. The findings showed that 4 students (13.33%) were at a low level of numeracy, 24 students (80.00%) at a medium level, and 2 students (6.67%) at a high level. Further analysis of students' numeracy skills across different geometric levels highlighted average proficiency scores of 81.66% in visualization, 66.67% in analysis, and a notably lower 40.00% in deduction. These results underscore the influence of culturally relevant numeracy problems on student performance. Consequently, these insights have significant implications for educational practices, particularly in the curation of instructional materials aimed at enhancing students' numeracy competencies.       Keywords: descriptive analysis, geometry domain, numeracy competency, cultural context of Bengkulu. DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1518-1531
