Abstract

ABSTRACTLearning mathematics is considered difficult material by students from elementary school to high school. Based on the results of observations made through interviews with Mathematics teachers, it was found that the problems experienced by students at SMAN 1 Sewon Bantul were found. The problems experienced by students are related to three dimensions and geometry transformation materials. In addition, there are still many students who cannot understand and visualize geometry material. How to make it easier to learn and understand abstract mathematics, especially geometry material, requires learning media, namely mathematics software. In learning mathematics, students need technology-based media that can represent their intuition in understanding a mathematical concept. The purpose of this service is to socialize GeoGebra Android as an open-source application to visualize geometry learning very accurately and more easily for high school students. The method used in this service activity is a training method through lectures, discussions, demonstrations, and assignments. With the use of applications in learning, it is expected to increase students' motivation and understanding in learning mathematics, especially geometry material. The results of the questionnaire from 24 respondents of class XII IPA 6 students obtained a percentage that as much as 72.7% agreed that learning using geogebra was very interesting and interactive in learning geometry material. Keywords: GeoGebra, geometry, training, math learning. ABSTRAKPembelajaran matematika dianggap materi yang sulit bagi para siswa.

Abstract

This study aimed to develop an ethnomathematics-based digital comic on Systems of Linear Equations in Two Variables (SLETV) and to examine its validity, practicality, and potential effectiveness in supporting students’ mathematical literacy. The study employed a Research and Development (R&D) approach using the 4D model, consisting of define, design, develop, and disseminate stages, although the development process was limited to the develop stage. A one-group pretest–posttest design was applied during the field-testing phase without a comparison group. The participants included 10 eighth-grade students and one mathematics teacher in the limited trial, followed by 30 eighth-grade students and one mathematics teacher in the field trial at Mangunan Eksperimental Junior High School. Data were collected through observations, interviews, questionnaires, and mathematical literacy tests. The literacy assessment was designed based on the OECD mathematical literacy processes of formulating, employing, and interpreting mathematics in contextual situations. The developed digital comic integrates Yogyakarta cultural contexts, including batik and local culinary products, into literacy-oriented SLETV learning activities. The validation results indicated a very high level of validity, with scores of 94% from content experts and 86% from media experts. Practicality was supported by positive responses from students (87.86%) and teachers (86%). The field trial results showed an improvement in students’ mathematical literacy, as reflected in an average N-Gain score of 0.58, categorized as moderate, and a statistically significant difference between pretest and posttest scores. These findings suggest that the developed digital comic has the potential to support mathematical literacy development in the tested context and may serve as a valid and practical learning medium for junior high school mathematics learning. This study contributes to mathematics education by demonstrating how local ethnomathematical contexts can be systematically integrated into digital comic media to promote OECD-oriented mathematical literacy in SLETV learning.

Abstract

Mathematics is often perceived as a difficult subject that triggers anxiety, especially among students facing academic pressure. This study aims to analyze and describe the level of mathematics anxiety experienced by final-year vocational high school students. Employing a descriptive qualitative approach, data were collected through a questionnaire distributed to six randomly selected Grade XII students from a vocational school in Gedangsari. The instrument consisted of 23 statements: 6 positive and 17 negative using a Likert scale to assess students’ anxiety. Data analysis followed the Miles & Huberman model, which includes data reduction, display, and verification. The results showed varying levels of mathematics anxiety: 2 students were categorized as having very high anxiety, 3 were in the moderate category, and 1 student experienced very low anxiety. Students with high anxiety reported symptoms such as trembling hands, increased heart rate, mental blocks, and a lack of confidence during mathematics tasks. Meanwhile, students with lower anxiety demonstrated greater emotional control, focus, and proactive engagement in learning activities. The findings indicate that mathematics anxiety can significantly hinder students’ cognitive and emotional capacity to learn effectively. This study contributes to educational psychology by providing insight into how mathematics anxiety manifests among vocational high school students. It highlights the importance of recognizing emotional factors in learning, particularly in high-pressure academic contexts. The results can inform teachers, counselors, and curriculum designers in developing supportive strategies to reduce anxiety and enhance mathematical engagement in vocational education. In conclusion, addressing mathematics anxiety is crucial for fostering a positive and supportive learning environment that empowers students to perform better academically. This research contributes to the understanding of mathematics anxiety in vocational education and emphasizes the need for empathetic, emotion-sensitive teaching approaches that support both cognitive and emotional student development.

Abstract

Students' errors in solving mathematical problems reflect their level of understanding and systematic thinking skills. This qualitative study aims to identify the types of errors and factors causing students' difficulties in solving the System of Linear Equations in Two Variables (SPLDV). The subjects were three eighth-grade junior high school students in Banjarnegara who were selected purposively. Data were obtained through written tests, in-depth interviews, and documentation. The results showed three main error categories: errors in modeling problems, calculations, and incomplete answer structures. The contributing factors include weak conceptual understanding, minimal contextual practice, the habit of solving problems instantly, and a lack of thorough problem interpretation. These findings are expected to provide an empirical basis for teachers and curriculum developers in designing effective learning and emphasizing conceptual understanding, contextual practice, reasoning, and systematic communication in SPLDV material
