Abstract

Self-confidence is considered a key psychological factor in enhancing students' ability to communicate mathematical ideas effectively. However, few studies have explored this relationship in the context of lower secondary education. This study aims to investigate the effect of self-confidence on the mathematical communication skills of eighth-grade students at SMP Negeri 5 Mataram during the 2024/2025 academic year. A quantitative approach with an ex post facto design was employed. A purposive sample of 29 students was selected, and data were collected using a self-confidence questionnaire and a mathematical communication skills test on the topic of systems of linear equations in two variables. The data were analyzed using descriptive statistics and simple linear regression. With the regression equation, the correlation coefficient, and the coefficient of determination. The results indicate that self-confidence has a significant positive effect on students' mathematical communication skills. These findings underscore the importance of cultivating students' self-confidence to support their development of mathematical communication skills.

Abstract

This study aims to describe the ability of grade XI students at SMA Negeri 1 Lembar in solving trigonometry story problems based on their level of mathematical literacy. This study employs a qualitative descriptive approach with six eleventh-grade students from class XI-1 as subjects, two each from the high, moderate, and low literacy categories. Data were collected through story problem tests and interviews, then analyzed using the Miles and Huberman model: data reduction, data presentation, and conclusion drawing. This study used a mathematical literacy framework that included formulate (formulating situations mathematically), employ (applying mathematical concepts, facts, procedures, and reasoning), and interpret (interpreting, applying, and evaluating mathematical results). The results of the study show that high-level students are able to perform all three processes well: understanding the context of the problem (formulate), applying formulas and procedures correctly (employ), and interpreting results and drawing conclusions according to the context (interpret). Meanwhile, intermediate-level students are sufficiently capable of identifying information and formulating problems (formulate), applying formulas although not yet systematically (employ), and drawing logical conclusions although there are still errors (interpret). Meanwhile, low-level students have difficulty formulating problems (formulate), use formulas in a limited and inaccurate manner (employ), and are unable to interpret results and draw conclusions correctly (interpret), although they are beginning to show basic understanding.

Abstract

The abstract nature of mathematics often makes students feel challenged, bored, and even anxious during the learning process. Therefore, mathematics learning should be interactive, enjoyable, and motivating. This study aimed to develop ethnomathematics-based comic learning media that connects the concept of cylindrical solid geometry with the traditional Sasak musical instrument Gendang Beleq to improve the mathematics learning outcomes of 29 seventh-grade students at SMPN 1 Lingsar, consisting of 10 male and 19 female students. The research employed a Research and Development (R&D) method using the 4D model (Define, Design, Develop, Disseminate), but was limited to the Develop stage. Research instruments included validation sheets, practicality questionnaires, and learning achievement tests. The analysis focused on the validity, practicality, and effectiveness of the media. The results indicated that the developed comic media was categorized as “highly valid” with an average percentage of 81.73%, “highly practical” with an average percentage of 92.65%, and “effective” with an N-Gain score of 0.73 (high category). Furthermore, this media successfully increased students’ learning interest, reinforced contextual conceptual understanding, and fostered an appreciation of local culture. The visual and narrative presentation of the comic made the learning process more enjoyable and meaningful.
