Abstract

This study was driven by the low mathematical problem-solving abilities of students. To address this issue, Think Talk Write (TTW) learning model, supported by GeoGebra software, was implemented as an intervention. The research aimed to determine whether students taught using the TTW learning model assisted by GeoGebra demonstrate greater improvement in mathematical problem-solving skills compared to those taught through conventional methods. This quasi-experimental study employed a quantitative approach with a non-equivalent control group design. The sampel in this research was class VII-G, with 28 students and Class VII-H, with 26 students. Data were collected using a mathematical problem-solving ability test and analyzed quantitatively. The gain index results indicated that the experimental class experienced a higher improvement in problem-solving skills than the control class. Furthermore, the t' test at a 5% significance level confirmed significant differences in mathematical problem-solving abilities between the two groups. Thus, it can be concluded that the TTW learning model assisted by GeoGebra software significantly enhanced students' mathematical problem-solving abilities compared to conventional learning methods.

Abstract

Geometry is one of the branches of mathematics that is important for students to master to support their profession in the future. However, there are still difficulties in geometry materials, especially transpormation geometry. In fact, there are many test questions about transformation geometry when taking the university or job entrance test. Therefore, it is necessary to conduct an analysis of spatial ability in solving the transformation geometry problem. This study uses a descriptive qualitative approach involving 24 grade XII students in Sumedang Regency as subjects. The results showed that students with high spatial abilities were able to visualize transformations well, although they still faced difficulties in translating them into proper mathematical models. In contrast, students with moderate and low spatial abilities showed significant challenges in understanding the basic concepts of geometric transformations. This study underlines the importance of applying spatial-based learning strategies to improve students' competence in understanding and applying geometry concepts effectively.

Abstract

Mathematics education in Indonesia continues to face challenges in accommodating diverse student characteristics and connecting mathematical concepts with meaningful cultural contexts. Uniform and procedural teaching practices often hinder the development of conceptual understanding and mathematical literacy. Although differentiated instruction and the integration of local wisdom have been discussed extensively, studies that systematically integrate both within digital mathematics learning media remain limited. This study aims to develop and evaluate BATIK BEKAL (Learning Mathematics through Local Wisdom), a web-based mathematics learning platform integrating differentiated instruction with Kasumedangan local wisdom. The study employed a Research and Development (R&D) approach using the ADDIE model. Participants included 50 mathematics teachers involved in the needs analysis and 25 junior high school students in a limited classroom implementation. Data were collected through questionnaires, expert validation instruments, classroom observations, and semi-structured interviews. The results indicate that the developed platform demonstrates high pedagogical, technical, and cultural validity and is perceived as practical by both teachers and students. The integration of local wisdom functions as a conceptual scaffold within differentiated mathematics learning. These findings contribute to the development of culturally responsive and adaptive digital mathematics learning media.

Abstract

The use of statistical concepts in real-life problems has become a challenge for students. This challenge is related to statistical reasoning (SR) ability which is influenced by several factors including cognitive style. Therefore, this research aims to understand the process of statistical reasoning from the perspective of cognitive style. A qualitative method was used and the subjects were students who are pre-service mathematics teachers. The instrument used were Group Embedded Figures Test (GEFT), statistical reasoning tests, as well as interview guidelines, and the data were analyzed using the qualitative descriptive method. The results showed statistical reasoning of the field independent pre-service mathematics teacher is better than the field dependent. Also, those with the same cognitive style, which is field independent, but different genders showed different reasoning processes. It was concluded that males have better Statistical Reasoning processes than females, and cognitive style as well as gender affect the reasoning abilities.

Abstract

Penelitian ini bertujuan memetakan tren pengembangan media pembelajaran berbasis teknologi untuk meningkatkan literasi matematika serta menelaah karakteristik efektivitasnya pada publikasi tahun 2020–2025. Metode yang digunakan adalah systematic literature review dengan alur PRISMA. Artikel dikumpulkan melalui penelusuran literatur terstruktur, kemudian diseleksi berdasarkan kriteria inklusi dan eksklusi hingga diperoleh 28 artikel yang relevan. Data diekstraksi untuk mengidentifikasi jenis platform yang digunakan, jenjang pendidikan sasaran, serta temuan utama terkait validitas, kepraktisan, dan efektivitas media terhadap literasi matematika. Hasil kajian menunjukkan adanya pergeseran dari perangkat lunak yang kompleks menuju platform no-code dan gamifikasi, seperti Canva dan Wordwall. Implementasi media paling banyak dilaporkan pada jenjang SMP. Secara umum, media interaktif yang ditinjau dinilai valid dan praktis serta menunjukkan dampak peningkatan literasi matematika pada kategori sedang hingga tinggi. Efektivitas paling kuat muncul ketika media dirancang kontekstual dan mendorong keterlibatan kognitif siswa melalui aktivitas penalaran, pemodelan, dan interpretasi representasi. Temuan ini menegaskan bahwa keberhasilan media lebih ditentukan oleh kualitas desain pembelajaran daripada kecanggihan aplikasinya, serta merekomendasikan strategi integratif dengan memadukan no-code, gamifikasi, dan perangkat math-specific secara terarah sesuai tujuan belajar. This study aims to map trends in the development of technology-based learning media to improve mathematical literacy and examine their effectiveness characteristics in publications from 2020–2025. The method used was a systematic literature review with the PRISMA flow. Articles were collected through a structured literature search, then selected based on inclusion and exclusion criteria to obtain 28 relevant articles. Data were extracted to identify the type of platform used, the target educational level, and key findings related to the validity, practicality, and effectiveness of the media on mathematical literacy. The results of the study indicate a shift from complex software to no-code and gamification platforms, such as Canva and Wordwall. Media implementation was most commonly reported at the junior high school level. In general, the interactive media reviewed were deemed valid and practical and showed a moderate to high impact on improving mathematical literacy. The strongest effectiveness emerged when the media was designed contextually and encouraged students' cognitive engagement through reasoning, modeling, and interpretation of representations. These findings confirm that the success of media is more determined by the quality of the learning design than the sophistication of the application, and recommend an integrative strategy by combining no-code, gamification, and math-specific tools in a targeted manner according to learning objectives.
