This research employs a quasi-experimental approach with a Nonequivalent Control Group Design. The research sample consists of two classes: Class VIIIA as the experimental group, which received the inquiry-based learning model assisted by Geogebra, and Class VIIIG as the control group, which used conventional learning methods. Data were collected through pretests and posttests consisting of five questions measuring students' mathematical problem-solving abilities. The results show that the experimental class experienced a significant improvement compared to the control class, as reflected in the higher N-Gain score in the experimental class (0.59) compared to the control class (0.26). Statistical tests also indicate a significant difference in the improvement of mathematical problem-solving abilities between the two groups (Sig. = 0.000). Thus, the implementation of the inquiry-based learning model assisted by Geogebra enhances students' mathematical problem-solving abilities better than conventional learning methods on the topic of polyhedral geometry</em></p> Amam Taufiq Hidayat ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ejurnal.undana.ac.id/index.php/fraktal/article/view/20776 Thu, 15 May 2025 04:06:32 +0000 Efektivitas Model Problem Based Learning Dalam Meningkatkan Pemahaman Konsep Perbandingan Matematika Siswa Sekolah Dasar https://ejurnal.undana.ac.id/index.php/fraktal/article/view/21103 <p>This research is based on the obstacles in understanding mathematical comparison story problems.

However, students' mathematical literacy in Indonesia remains relatively low, as shown by international assessments and classroom observations. One effective approach to improve mathematical literacy is STEAM-based learning (Science, Technology, Engineering, Art, and Mathematics), which emphasizes interdisciplinary collaboration in solving real-world problems. This study aims to enhance junior high school students’ mathematical literacy through the implementation of STEAM-based learning supported by an interactive magazine e-module. The research employed an experimental method with a one-group pretest-posttest design. Data were analyzed using normality testing and non-parametric hypothesis testing to examine students’ learning progress, along with gain analysis to measure the level of improvement. The results show that students’ mathematical literacy improved after the implementation of the learning approach. These findings support that STEAM-based learning assisted by an interactive e-module can serve as an effective alternative to enhance students’ understanding and application of mathematical concepts in real-life contexts</p> Iska Barbara Nainggolan, Gugun Manosor Simatupang, Roseli Theis, Novferma Novferma ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ejurnal.undana.ac.id/index.php/fraktal/article/view/21247 Thu, 15 May 2025 04:10:02 +0000 Kesamaan Gender Pada Literasi Matematis Siswa: Implikasi Bagi Kesetaraan Gender Di Bidang STEM https://ejurnal.undana.ac.id/index.php/fraktal/article/view/21158 <p>An adequate mathematical literacy allows individuals to comprehend core concepts in STEM fields, such as complex problem solving, analytical thinking, and methodical approach to challenges. Indonesian students’ mathematical literacy was still categorized in the low group according to PISA survey. In some countries, boys still outperformed girls which, in the long run, can lead to woman underrepresentation in STEM fields. Using secondary data collected during 2018/2019 academic year in Kupang, this research focused on examining public middle school students’ overall mathematical literacy based on gender as well as their performance in the process and content areas. The technique used to select 377 participants was two-stage cluster randomized sampling. Although there were only two categories of gender, the data were analyzed using One-Way ANOVAs to open possibilities for future research to analyze more than two groups. After the normality and homogeinity of variance had been confirmed, the data was then analyzed to examine gender patterns. The results revealed gender similarities in the overall as well as in the content and process domain of public middle school students’ mathematical literacy in Kupang. The results endorsed gender equality in mathematical literacy and contributed to career aspirations and decreasing gender prejudice in STEM education.</p> Daniel Williams Fointuna ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ejurnal.undana.ac.id/index.php/fraktal/article/view/21158 Thu, 29 May 2025 14:25:17 +0000 Penerapan Model Discovery Learning Berbantuan E-Worksheet Untuk Meningkatkan Hasil Belajar Materi Turunan Fungsi Aljabar https://ejurnal.undana.ac.id/index.php/fraktal/article/view/16646 <p>Based on the interview results, student learning outcomes at SMAN 3 Kupang for algebraic function derivative material are low, which is just about 50% students passing the semester test. Students have difficulty in understanding the material from the book, and only some students are active in giving responses. This study aims to improve the learning outcomes of algebraic function derivative material in class XI MIPA SMAN 3 Kupang by using the Discovery Learning model assisted by eworksheet to make students become more active and the learning process becomes more interesting. This research is a class action research and the subjects are 36 students &nbsp;class XI MIPA 1 and researchers as teachers. The results showed that student learning outcomes had improved, shown by the presentation of classical completeness which is 62.5% in cycle I and increased to 87.5% in cycle II. The percentage of teacher activity is 91.67% in cycle I became 93.75% in cycle II and it is in the very good category. The percentage of student activity is 84.38% in cycle I became 85.98% in cycle II and it is in the good category so it can be concluded that the discovery learning model assisted by eworksheet can improve the learning outcomes of algebraic function derivative material in class XI MIPA SMAN 3 Kupang.</p> Elisa Gaudensia Wuwur ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://ejurnal.undana.ac.id/index.php/fraktal/article/view/16646 Fri, 30 May 2025 00:00:00 +0000 Desain Pembelajaran Berdiferensiasi Pada Materi Fungsi Linear Siswa Kelas VIII SMP Negeri 17 Kota Kupang https://ejurnal.undana.ac.id/index.php/fraktal/article/view/16828 <p>Differentiated learning is a learning approach designed to address the diverse learning needs of students. The aim of this research is to develop a learning design that is suitable for the varying levels of understanding and competency among students, and is effective in meeting the specific learning needs of students at SMP Negeri 17 Kota Kupang, particularly in comprehending the topics related to linear functions, specifically the subchapter on gradients. The research methodology employed is design research, which involves three stages: the preliminary stage (initial design), the implementation stage (experimentation), and the retrospective analysis stage (retrospective analysis). Data collection techniques and instruments used include tests (diagnostic assessment and formative assessment), interviews, and observations. The data analysis techniques employed encompass qualitative and quantitative descriptive analysis. This research yields a learning design that caters to students' needs and provides ample learning opportunities. Each activity in LKPD aids students in grasping concepts such as determining the gradient of a straight line passing through a central point and another point, finding the gradient of a line passing through two points, determining the gradient of a line from its equation, and applying these skills to solve real-life problems involving gradients. The research findings indicate an improvement in students' understanding and abilities, thus confirming the effectiveness of the developed learning design in enhancing students' learning outcomes.</p> <p>Keywords: Differentiated Learning, Linear Function</p> Gnadia Rambu Nodu Jaki, Damianus D.
