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

This study aims to describe students’ mathematical communication skills in the topic of two variable linear equation systems, viewed from the perspective of extrovert and introvert personality types among eighth-grade students at SMPN 1 Labupi. This type of research is qualitative with a descriptive method. The research instruments consisted of a questionnaire, a test, and interview guidelines. Of the 34 students who completed the personality type questionnaire, 14 were identified as extroverts and 20 as introverts. Subsequently, the students were given a mathematical communication skills test. Based on the results, four research subjects were selected, consisting of two extroverted students and two introverted students. The qualitative data analysis used in this study consists of three stages: data reduction, data presentation, and drawing conclusions. The results showed that both high and low level extrovert students demonstrated good mathematical communication skills, as they were able to meet the indicators of mathematical communication skills, namely writing, reading, and mathematical expression. Extroverted students were more proficient in explaining problem solutions compared to introverted students. High-level introverted students also showed good mathematical communication skills, fulfilling the aspects of writing, reading, and mathematical expression. Meanwhile, low-level introverted students were only able to fulfill the writing aspect and still experienced difficulties in meeting the reading and mathematical expression aspects.

Abstract

Mathematical representation ability is an essential aspect of solving mathematical problems, particularly in the topic of relations and functions. However, in practice, many students struggle to express mathematical ideas through verbal, visual, and symbolic representations. One factor that may influence this ability is self efficacy, or students’ belief in their ability to complete mathematical tasks. This study aims to describe students’ mathematical representation ability in solving problems on relations and functions viewed from their self efficacy. The research was conducted at MTs Negeri 2 Mataram in the academic year 2024/2025 using a descriptive qualitative method. The subjects consisted of three eighth-grade students representing high, moderate, and low self efficacy categories based on questionnaire results. The instruments used included a self-efficacy questionnaire, a mathematical representation test, and interview guidelines. The findings show that students with high self-efficacy were able to fulfill all types of representation accurately and completely. Students with moderate self efficacy showed partial ability but were inconsistent. Meanwhile, students with low self-efficacy experienced difficulties in all forms of representation. These findings indicate a tendency that self efficacy plays a role in students’ quality of mathematical representation ability.

Abstract

Higher-order thinking skills are skills that are an important aspect of teaching and learning mathematics. Mathematics and culture have a very close relationship, so the development and application of mathematical concepts in the learning process must be based on situations of daily life or local culture. In 2021, Researchers have developed a textbook of Logic and Set containing ethnomathematics oriented toward higher-order thinking skills. The textbook meets the 'Very Good' category on the validity test after being assessed by five experts. This year, the research focuses on the implementation and evaluation of the textbook in Logic and Set courses. The purpose of this research was to describe the feasibility level of the textbook. ADDIE's design research was used in this development research. The trial subjects in this research were 140 students in the Department of Mathematics Education, Faculty of Teacher Training and Education, Universitas Mataram who were taking the Logic and Set courses in the 2021/2022 academic year. Data collection techniques in this research were practicality questionnaires and higher-order thinking skills tests. The results of the data analysis for the practicality assessment of the textbook showed an average score of 81.44, which met the practical classification. Then the average value of the students in the final value of the Logic and Set courses is 81.90. In addition, the percentage of students who achieved a score of 75 was 76% or 106 students. Therefore, it can be concluded that the textbook meets the effective criteria.
