Mathematics and culture have a strong relationship in life. In Indonesia, culture is different from local wisdom, and the culture of certain community groups or tribes that support mathematical activities is called ethnomathematics. One example is cultural heritage buildings, such as the ANRI (National Archives of the Republic of Indonesia) building which was founded in 1750 in DKI Jakarta Province, precisely on Jalan Gajah Mada, West Jakarta. The purpose of the research that we use, which is exploratory with this ethnographic method, is to find and categorize the mathematical concepts contained in the ANRI building which is one of the sources of learning mathematics and efforts to develop ethnomathematics as a basis for mathematics learning. This study focuses on understanding the informal mathematical knowledge acquired by local people from their environment and culture, especially those related to cultural heritage sites, which are referred to as ethnomathematics. The study findings show that the National Archives Building is a significant cultural heritage site with historical and architectural significance. The architectural features of the building, such as the rectangular and trapezoidal shapes of the main structure and roof, reflect various geometric concepts. Overall, this research emphasizes the importance of preserving cultural heritage and documents in the National Archives to retain the historical knowledge contained within. Ethnomathematics provides a valuable framework to explore and appreciate mathematical concepts embedded in cultural artifacts, promoting a deeper understanding of mathematics through real-world activities and cultural practices.

Puspa Nur Afifah — 2024-12-24

This study aimed to test the effectiveness of using YouTube and e-modules for statistics learning for social science students enrolled in statistics courses. Statistics is often considered an abstract and difficult subject to understand, which can trigger anxiety and reduce students' learning motivation. A total of 31 students of the Islamic community development study program at UIN Sultan Maulana Hasanuddin participated in this study. Students were divided into one group that underwent two learning sessions: first, they studied frequency distribution material with YouTube learning media (audiovisual), and second, central measurement with e-module learning media (text-based), with a comparative quantitative approach evaluated through pretest and posttest. The results showed that both YouTube and e-modules were equally effective in improving students' understanding of statistics. However, 84% of students who used YouTube showed a significant increase in understanding, while only 68% showed an increase after using the e-module. The average increase in scores with YouTube was 13.81 points, higher than 4.77 points on the e-module. The paired sample t-test indicated that YouTube was significantly more effective than the e-module, with a p-value < 0.05. YouTube’s advantages mainly lie in its visual and interactive features that help facilitate the understanding of abstract concepts in statistics. This study recommends integrating YouTube and e-modules to optimize statistics learning outcomes, especially in the social sciences.

DEFRAGMENTATION OF CONSTRUCTION HOLE THINKING PROCESS OF JUNIOR HIGH SCHOOL STUDENTS IN SOLVING NUMERATION LITERACY QUESTIONS

Dewi Nurmalitasari — 2024-12-25

Teachers must be aware of and take action regarding students' errors in creating incomplete mathematical concepts, also referred to as construction holes, particularly when it comes to answering numeracy literacy questions. This will help students rebuild their understanding of numeracy literacy questions overall. By using diagrams to depict the answers to numeracy literacy questions both before and after the defragmentation process, this study seeks to identify the places where pupils fall short conceptually. A mixed-methods research methodology was employed for this study, which was conducted in two phases: quantitative analysis was used in the first phase, and qualitative analysis in the second. Based on the research findings, the numeracy component of the statistics curriculum is where the gaps in students' thinking processes are located. Students' thought structures can be strengthened by the use of defragmentation. When answering questions on numeracy and literacy, the defragmentation method utilized is scaffolding at level two, which consists of explaining, reviewing, and restructuring. The mean, mode, and median material in the student results contained construction holes that were later resolved through a scaffolding type that involved three steps: explaining, reviewing, and restructuring. This process helped students avoid making mistakes when answering the questions about the mean, mode, and median.
