Students who experience learning difficulties in natural science (science) lessons obtain unsatisfactory learning results and grades that do not fulfil the KKM. Quantitative research method is a research method based on positive philosophy which is used to examine research instruments and quantitative/statistical data analysis, with the aim of testing predetermined hypotheses. In this research, researchers used experimental methods. The student's natural science (science) learning outcomes before being given treatment obtained an average score of 60.46. The normality test result is 0.150, so it can be concluded that the pre-test learning results are normally distributed. The student's natural science (science) learning outcomes after being given treatment obtained an average score of 82.46. The normality test result is 0.094, so it can be concluded that the post-test learning results are normally distributed. This can be proven with a correlation coefficient value of 0.960 which is a very strong interpenetration. The results of the T-test calculation to find out whether the hypothesis is accepted or rejected, the tcount 16,830 is greater than ttable 1,706, which means that there is an influence of Problem-Based Learning Based on Song Media on student learning outcomes. Thus, Ha is accepted and Ho is rejected.

This study aims to determine whether the implementation of problem-based learning models can improve students' mathematical numeracy literacy skills in class VIII SMP Negeri 30 Medan. This research method uses Classroom Action Research (CAR). The research procedure is in the form of a cycle. Each cycle consists of 4 stages, namely: planning, implementation of action, observation and reflection. Data collection techniques through observation and tests. This data collection uses several instruments in the form of teacher observation sheets, student observation sheets. Meanwhile, to determine the ability of students' mathematical numeracy literacy tests were used. The results showed that the use of problem-based learning models can improve students' mathematical numeracy literacy skills in the mathematics subject matter of cubes and blocks.

Ruma Bolon adalah rumah tradisional kebanggaan Suku Batak Toba yang memiliki nilai budaya dan gaya bangunan yang unik. Tujuan dari penelitian ini adalah untuk mengkaji nilai matematika yang terkandung dalam pembuatan dan desain Ruma Bolon, serta mendeskripsikan bagaimana nilai-nilai matematika tersebut mencerminkan konsep geometri dan proporsi yang ada dalam bangunan Ruma Bolon dari suku Batak Toba. Pendekatan etnomatematika digunakan untuk menyelidiki bagaimana konsep-konsep matematika berhubungan dengan elemen-elemen bangunan tradisional suku Batak Toba ini, seperti simetri, bentuk geometris pada struktur bangunan, dan pola ukiran. Hasil penelitian menunjukkan bahwa Ruma Bolon tidak hanya berfungsi sebagai tempat tinggal, tetapi juga memiliki simbolisme matematika yang dalam dan unik. Simbolisme ini mencerminkan keseimbangan di langit yaitu kaitannya dengan Mula Jadi Nabolon, keseimbangan dalam kehidupan sosial atau bermasyarakat, dan penghormatan kepada alam dan leluhur sebagai suatu kesatuan yang utuh. Studi ini menghasilkan kesimpulan bahwa matematika dalam bangunan Ruma Bolon bukan sekadar estetika, tetapi juga merupakan manifestasi dari nilai-nilai budaya yang mengakar kuat dan bermakna yang dalam untuk kehidupan masyarakat Batak Toba.

PISA is a prestigious platform for assessing students' learning achievements globally, including 4C skills: creative thinking, critical thinking, communication, and collaboration. However, the 2022 PISA results once again showed disappointing achievements for Indonesia. Indonesian students struggle with solving complex problems (critical thinking), have difficulty conveying ideas effectively (communication), are less prepared for creative challenges (creative thinking), and lack effective collaborative learning approaches. This research aimed to analyze the 4C skills of students at SMP Negeri 31 Medan. The study involved 29 students from class IX-3. Data were collected using two selected essay questions from the 2022 PISA mathematics test, specifically designed to assess 4C skills through indicators like interpreting, formulating, and reasoning. Collaboration was assessed through semi-structured interviews with the class teacher to gain insights into students' interaction and teamwork skills, complementing the written test results. Qualitative descriptive analysis was used to interpret students' written responses, while collaboration data were analyzed based on teacher observations. Assessment criteria followed established indicators for critical thinking (Employ and Evaluate), creativity (formulate), communication (interpret), and collaboration (effective teamwork). The results indicate that 69.56% of students correctly answered interpretation questions (communication, level 3), 39.13% and 43.47% answered employability questions correctly (critical thinking, levels 2 and 1a), and 30.43% correctly answered formulation questions (creativity, level 2). However, teacher observations revealed that students still struggle with effective collaboration, reflecting a broader challenge in fostering teamwork and peer learning. Overall, although communication skills are relatively strong, significant improvements are needed in critical thinking, creativity, and collaboration.

This research examines the transformation of mathematics learning through the combination of gamification and the ethnomathematics approach using the literature study method. In an effort to enhance student engagement and understanding, the combination of these two approaches offers significant potential in creating a more engaging and culturally relevant learning experience. Through the analysis of various literature sources, this research explores the concepts, strategies, and best practices that have been implemented in the context of mathematics education. The research findings indicate that gamification can enhance student motivation with game elements, while ethnomathematics enriches learning with local cultural contexts. However, this research also identifies the challenges faced, such as the limited training for educators, resistance to pedagogical changes, and the need for resources that support effective implementation. These findings provide valuable insights for educators, curriculum developers, and researchers in designing innovative and contextual learning approaches, as well as opening up opportunities for further research in the field of mathematics education.
