Abstract

The achievement of high school graduates' competence is continuously improved by the government in Indonesia, one of which is by implementing the Minimum Competence Assessment. The main problem in its application is the limitations of similar problem models provided in classroom learning so that students are not accustomed to solving them. The purpose of this research is to produce mathematical reasoning questions using the Minimum Competence Assessment model for junior high school students that are valid, reliable, and have a potential impact. This research is development research with two stages of developing Tessmer’s model, namely: (1) Preliminary and (2) formative evaluation stage, which consists of self-evaluation, prototyping (expert reviews and small group), and field tests. The trial subjects of this study were 25 students of class VIII Bengkulu state junior high school 7 in Bengkulu City. The results of the study obtained questions that met valid criteria with an Aiken index each of which was more than 0.5. The questions meet reliable criteria with a count of more than 0.6 and are in the high category. The questions have a potential impact with sufficient students' selection abilities on average and students giving a good response of more than 50.00%. The suggestion from the research is that the teacher encourages choosing a real context to present the problem in mathematics learning.Keywords: development research, instrument test, mathematical reasoning, minimum competence assessment.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1515-1526

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

Abstract

The implementation of distance learning at every level of education, significantly higher education, has various obstacles. One of them was the lack of teaching materials that can support students to learn both guided and independent. Learning resources that were commonly used did not interactively support learning. This study aimed to determine the effectiveness of interactive e-modules based on project-based learning in mathematical literacy skills and student confidence in number theory courses. The type of research used was quasi-experimental with a quantitative approach. The research subjects were students of the 2021 mathematics education study program, which consisted of two classes with 32 experimental classes and 36 control classes. Technique sample used a census where each class was selected and determined treatment. Data collection techniques were used tests with literacy ability test instruments and self-confidence questionnaires. Data analysis with descriptive analysis and hypothesis testing using MANOVA and the effectiveness of learning with interactive e-modules were analyzed using a one-sample t-test.The results showed that the application of project-based learning-based interactive e-modules was effective in students' literacy skills, with a t-count result of 6.949 and a significance level of 0.000. The use of e-modules is more effective than the control class, with an average literacy ability of 81.25 in the experimental class and 62.91 for the control class. I am judging from the adequate self-confidence with a high category and the results of t count of 4.179 significant at 0.05 alpha. The results of the Manova analysis show that the application of interactive e-modules is more effective in terms of literacy skills and student self-confidence, with a significant Hotelling's trace of 0.000

Abstract

Indonesia’s low numeracy performance in international assessments highlights the need for more effective and engaging instructional strategies. This study analyzed the influence of the Quizizz application on supporting the numeracy ability of junior high school students in Bengkulu City. Using a quantitative approach, data were collected from 70 students through a Likert-scale questionnaire measuring ten indicators of Quizizz utilization. Multiple linear regression analysis using SPSS 25 revealed that the model was statistically significant (F = 3.303; p = 0.002), with the independent variables collectively explaining 36.3% of the variance in numeracy skills (Adjusted R² = 0.253). Two indicators—conceptual understanding (x1) and critical–creative thinking (x5)—significantly affected numeracy ability, whereas other indicators showed no partial influence. The model met classical assumption requirements, including linearity and homoscedasticity. These findings confirm that Quizizz is an effective digital learning tool that enhances students’ numeracy through interactive and motivating learning experiences.

Abstract

This systematic literature review analyzes international evidence on proportional reasoning (PR) in K–12 education and teacher training. We synthesized eight studies and identified four key patterns. Contexts with hands-on activities help students transition from intuitive to formal strategies. Students often succeed with probability ratios, but struggle with visual biases. Example-based practice with self-explanation improves probabilistic reasoning, especially for less prepared students. Finally, diagnostic tools such as construct maps are useful for tracking student progress from "combined unit" to "multiplicative comparison" understanding. Our review recommends designing a clear progression for ratios, rates, and probabilities; teaching anti-bias strategies; embedding routines of example problems; and using construct map-guided assessments. This synthesis provides a clear action lens to improve PR instruction by integrating student cognition, task design, and teacher practices.

Abstract

This study aims to describe students’ mathematical reasoning processes within the framework of Realistic Mathematics Education (RME), particularly focusing on how learners develop proportional and logical reasoning through contextual tasks. Using a qualitative case study design, the research involved classroom observations, task-based interviews, and analysis of students’ written work collected from two purposively selected university students. Data were examined through thematic analysis to identify patterns of reasoning related to multiplicative strategies, symbolic manipulation, and the use of contextual or visual representations. The findings indicate that both students demonstrated strong procedural and symbolic proficiency, especially in applying logical laws and performing formal transformations; Student A showed consistent vertical mathematization, while Student B provided partial conceptual explanations but lacked systematic justification. However, neither student exhibited meaningful horizontal mathematization, contextual interpretation, nor the use of emergent models characteristic of RME-based learning. Their reasoning predominantly reflected imitative-procedural approaches rather than creative or relational reasoning, suggesting that their learning experiences did not sufficiently support guided reinvention or conceptual development through realistic contexts. These results highlight the need for instructional designs that integrate contextual tasks, visual models, and scaffolding aligned with RME principles to foster deeper conceptual understanding and more flexible reasoning.
