Abstract

The purpose of this study was to determine whether there is an effect of implementing Contextual Teaching and Learning (CTL) based on Augmented Reality in developing students’ spatial visualization abilities and geometric reasoning on solid geometry material for eighth-grade students at SMPN 1 Bandar Pulau. This research used a quasi-experimental method with a Two Group Pre-Test and Post-Test research design. The population of this study consisted of all eighth-grade classes, totaling four classes. The research sample consisted of two classes selected through purposive sampling determined by the school. The control class used the CTL learning model, while the experimental class used Augmented Reality-based contextual learning. After the learning process was completed, the post-test results showed that the average score of the experimental class was 71.696 and the control class was 67.048. The results of the t-test obtained t_count = 1.708 > t_table = 1.669, therefore Hₐ was accepted. In addition, this study also used questionnaires to measure students’ perceptions of Augmented Reality-based contextual learning. The questionnaire results indicated that the majority of students gave positive responses toward the use of AR in learning. A total of 42.9% of students strongly agreed and 43.4% agreed that contextual learning with AR made the learning process more interesting, enjoyable, and helpful in understanding solid geometry concepts. Thus, it can be concluded that there is an effect on students’ learning outcomes through the use of Augmented Reality-based contextual learning in developing students’ 3D visualization abilities and geometric reasoning.

Abstract

This study aims to describe students’ emotional regulation based on gender in solving word problems on fraction material. This research employed a qualitative descriptive approach involving 27 seventh-grade students at UPTD SMP Negeri 1 Aek Kuasan, consisting of 16 male students and 11 female students . Data were collected through tests, questionnaires, observations, interviews, and documentation. The results showed that students' emotional regulation was categorized into high, medium, and low levels. Most students were in the medium category (40.7%), followed by high (29.6%) and low (29.6%) categories . Based on gender, female students tended to have better emotional regulation than male students, as indicated by a higher percentage in the high category. These findings indicate that emotional regulation plays an important role in helping students remain calm, focused, and systematic in solving mathematical word problems. Therefore, emotional aspects should be considered in mathematics learning, especially when dealing with complex problems.

Abstract

This study analysed the effectiveness of Malay ethnomathematics-based mathematics learning using the Indonesian Realistic Mathematics Education (PMRI) approach on the numeracy literacy of seventh-grade students at SMP Negeri 7 Kisaran. A quasi-experimental method with a nonequivalent control group design was employed. The participants were 64 students, consisting of an experimental class (n = 32) and a control class (n = 32). The experimental class learned through PMRI activities using Malay-Asahan cultural contexts, including traditional market transactions, songket motifs, local measurements, and daily community practices, whereas the control class received conventional instruction. Data were collected using essay-based numeracy literacy tests validated by experts and tried out before implementation. The results showed that the two classes had comparable initial ability (pretest means of 52.3 and 51.8; Sig. = .803). After the treatment, the experimental class achieved a higher posttest mean score (81.4) than the control class (70.2). The independent samples t-test indicated a significant difference (t = 5.42; df = 62; Sig. < .001) with a large effect size (Cohen’s d = 1.36). The experimental class N-gain (0.61) was also higher than the control class N-gain (0.38). These findings indicate that Malay ethnomathematics-based PMRI effectively improves students’ numeracy literacy.
PEMANFAATAN BUDAYA LOKAL DALAM PEMBELAJARAN MATEMATIKA MELALUI MEDIA SCRAPBOOK UNTUK MENINGKATKAN LITERASI MATEMATIKA SISWA DI SLB SWASTA OSAKALI ASAHAN Anim Anim; Putri Lidiana Permatasari; Syahriani Sirait; Muhammad Tuah Anggana Manulang; Bella Norma Iona

Abstract

Abstract: This article discusses the introduction of local culture in mathematics learning,designed in the form of a scrapbook media, to enhance mathematical literacy skills of students at SLB Swasta Osakali, focusing on flat shapes material. The scrapbook media is designed to link the learning material with local cultural elements familiar to the students, aiming to strengthen mathematical literacy. This service is specifically conducted for students with hearing impairments to observe changes in mathematical literacy skills before and after the implementation of the scrapbook, as well as to evaluate its effectiveness in stimulating students' mathematical literacy. The method used in this activity is a training approach, which includes the dissemination of the material, demonstration of scrapbook media usage, and training skills to relate mathematical concepts to local culture. A quasi-experimental approach with a pretest-posttest design is also applied to measure the improvement in students' mathematical literacy. The target group consists of 9 senior high school students with hearing impairments at SLB Swasta Osakali Asahan, assisted by class teachers as communication intermediaries. Evaluation is conducted at the end of the training by distributing questionnaires to assess participants' understanding of the material and the scrapbook media. The evaluation results show that all students demonstrated improved knowledge, both from individual questionnaire calculations and students' participation and enthusiasm during the scrapbook activity. Thus, the use of scrapbook media based on local culture can be an innovative strategy in inclusive education for children with special needs. Keywords: mathematical literacy; local culture; scrapbook media; inclusive education. Abstrak: Artikel ini membahas pengenalan budaya lokal dalam pembelajaran matematika yang dirancang dalam bentuk media scrapbook untuk meningkatkan kemampuan literasi matematika siswa di SLB Swasta Osakali, pada materi bangun datar. Media scrapbook ini dirancang untuk mengaitkan materi pembelajaran dengan elemen budaya lokal yang dikenal oleh siswa, guna memperkuat literasi matematika. Pengabdian ini difokuskan pada siswa penyandang tunarungu untuk menganalisis perubahan kemampuan literasi matematika sebelum dan sesudah penerapan scrapbook, serta mengevaluasi dampaknya. Metode yang digunakan adalah pelatihan yang meliputi penyuluhan substansi materi, demonstrasi penggunaan media scrapbook, serta pelatihan keterampilan mengaitkan konsep matematika dengan budaya lokal. Pendekatan kuasi eksperimen dengan desain pretest-posttest juga diterapkan untuk mengukur peningkatan kemampuan literasi matematika siswa. Target pelatihan adalah 9 siswa tunarungu tingkat SMA di SLB Swasta Osakali Asahan, yang didampingi oleh guru kelas sebagai perantara komunikasi. Evaluasi dilakukan dengan menyebarkan kuesioner untuk mengukur pemahaman peserta terhadap materi dan media scrapbook. Hasil evaluasi menunjukkan bahwa seluruh siswa mengalami peningkatan pengetahuan, dilihat dari skor kuesioner dan antusiasme siswa selama pelatihan. Dengan demikian, penggunaan media scrapbook berbasis budaya lokal dapat menjadi strategi inovatif dalam pendidikan inklusif untuk anak berkebutuhan khusus. Kata kunci: literasi matematika, budaya lokal, media scrapbook, pendidikan inklusif.

Abstract

This study aims to analyze the effect of the CTL (Contextual Teaching and Learning) model assisted by the Xsolver application to improve students' numeracy literacy skills. The research method used is quasi-experimental. The population included all Grade VIII students of SMPN 3 Kisaran in the 2024/2025 school year. The study sample comprised two classes: Class VIII-1 as the experimental group and Class VIII-3 as the control group,each containing 30 students. The instrument used was a validated essay test consisting of 5 questions. Data analysis revealed an average post-test score of 71.83 for the experimental class and 57.5 for the control class. The t-test results of post-test scores showed a significant difference in numeracy literacy skills between the experimental and control classes. It can be concluded that the Contextual Teaching and Learning (CTL) model assisted by the Xsolver application has a positive effect on improving students' numeracy literacy skills.
