<![CDATA[This study aims to improve students' mathematical problem-solving abilities through the implementation of the inquiry-based learning model assisted by Geogebra on the topic of polyhedral geometry at MTsN 2 Aceh Utara. 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]]>

<![CDATA[The ethnomathematical excavation of the Takpala Indigenous Village community in this study focused on the position of the fingers of the indigenous people in counting. The purpose of this study was to determine the types of numbers used by indigenous peoples based on the position of the fingers in their daily lives. To find out the type of number in question, this study uses an ethnographic method. The results showed that the use of the finger position in counting carried out by the Takpala Indigenous Village community contained modulo 10 and modulo 5 (modulo 10-5). Based on the position of the fingers, the mathematical modeling is obtained in the form of: “for every and applies ”.]]>

<![CDATA[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.]]>

<![CDATA[Mathematical literacy plays a crucial role, as many daily human activities are related to mathematics and require literacy skills to solve real-life 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]]>

<![CDATA[This study is based on the low student learning outcomes in trigonometry material. This study aims to describe the improvement of learning outcomes of class X students of SMA Negeri 3 Kota Kupang by applying the Problem Based Learning model on trigonometry material with the help of interactive power point. This research was conducted with research procedures based on the Kemmis and Mc. Taggart model which consists of four research components, namely plan, act, observe, and reflect. The data collection techniques were observation and tests. The instruments used were teacher and student observation sheets and learning outcome test sheets. The results of this study showed that the classical student learning outcomes in cycle I were 63.33% which increased to 83.33% in cycle II. Meanwhile, the observation result of teacher activity while teaching in cycle I obtained a percentage of 93.1% seen to increase to 97,9% in cycle II and the observation result of student activity during the learning process in cycle I obtained a percentage of 86.8% increased to 95,8% in cycle II. Therefore, the application of problem-based learning model on trigonometry material with the help of interactive power point can improve the learning outcomes of students of class X SMA Negeri 3 kupang city.]]>

<![CDATA[The connection between mathematics and culture is a strong foundation for enriching the mathematics learning process. Therefore, it is hoped that school mathematics learning activities can be better adapted to the cultural context of students so that mathematics can be more easily understood by students. One cultural context that can be used is the ethnomathematics of Songke Manggarai woven cloth. The type of research used in this research is qualitative research with a qualitative descriptive research method with an ethnographic approach. In this research, the instruments used were interviews and observations. Data collection techniques in this research consist of observation, interviews and documentation. The data analysis technique used in this research is the interactive model from Miles & Huberman (1994), which states that the data collection stage consists of three activities that occur simultaneously, namely data reduction, data presentation, and conclusion drawing/verification. Based on the results of this ethnomathematics exploration research, it can be concluded that there are mathematical concepts in the Songke Manggarai woven cloth of Golo Ronggot Village, both in the initial process and in the stages of the weaving process.]]>
