Abstract

This research aims to determine the increase in student activity and learning outcomes in flat building materials through the use of the think pair share (TPS) design. The research design used to achieve the objectives of this research was classroom action research conducted at SMP Negeri 1 Indramayu. Apart from that, the subjects in this research were 32 students in class VII B, while the instruments used in this research were student observation sheets which aimed to measure activity and formative tests given each cycle. Next, deep data analysis study uses pattern study quantitative descriptive for measure enhancement results Study mathematics students through test formative and measuring enhancement activities carried out every cycle. The results of data processing on learning outcomes obtained an average of 65.09 for cycle I, cycle II of 74.07, and cycle III of 80.45. Likewise, the increase in the number of students reaching completeness Study that is from cycle I as much 5 students out of 32 students or 22%, cycle II as many as 15 students out of 31 students or 47% of the criteria high completeness, and in cycle III there were 26 students out of 31 students or 81% included in the category the criteria for completeness are very high. Next, based on the results of data processing of student activity during the learning process obtained that cycle I had not reached the active category (A) (24 students out of 32 were inactive or 25% from target 75% so cycle I Not yet reach category active). In Cycle II there was an increase from Cycle I to reach the active category (A), namely 20 students were active in the learning process and 11 students were still not actively involved in the learning process. Additionally, in Cycles III there was a significant increase in reaching the active category (A), namely, there were 25 students, or 81% of students involved in the learning process, while the rest were still not active. This matter shows that using the Think Pair Share (TPS) design through the involvement of students and mathematics teachers can increase student activity and learning outcomes in plain material.

Abstract

This research aims to identify and reveal the connection between ethnomathematics and ethnomodeling in Indonesia’s bocah sukerta traditional ceremony. An ethnographic design was used to reveal the research objectives. The participants involved in this research were the ceremony leader and bocah sukerta. Next, the data obtained from interviews and observations were analyzed using the content analysis method. The research results reveal that the ethnomathematics connection is reflected in weighting activities (weighing objects, calculating total weight, making comparisons, and balancing weights) and the shape of the scales (the basic shape represents 2D geometry, and the frame shape represents 3D geometry). This research also concludes that the ethnomodeling connection produces mathematical understanding, especially in arithmetic operations, weight measurements, weight conversions, mathematical equations, basic statistics, Cartesian coordinates, the center point of a square, and determining a pyramid’s distance, length, and area. Furthermore, this research concludes that the relationship between ethnomathematics and ethnomodeling in the bocah sukerta traditional ceremony can be used to construct didactic designs for square material volumes and rectangular pyramids.

Abstract

Ethnomathematics research has documented mathematical concepts embedded in various Indonesian cultural artifacts; however, few studies have transformed these findings into validated instructional materials, and the traditional houses and accessories of the Dayak Bumi Segandu Indramayu community remain unexplored in mathematics education literature. This study addressed this gap by combining an ethnographic exploration with the ADDIE development model to design and validate an ethnomathematics-based learning module on three-dimensional geometry for seventh-grade junior high school students. The research was conducted at Padepokan Nyi Ratu Kembar Jaya, Krimun Village, Indramayu Regency. Data were collected through observations, interviews, and documentation involving four purposively selected participants representing the community leadership and members. Qualitative data were analyzed using coding, data reduction, data display, and conclusion drawing assisted by ATLAS.ti 8. The exploration identified mathematical concepts embedded in traditional houses and cultural accessories, including lines, angles, plane figures, and solid figures, which were integrated into the module. Validation by two mathematics education experts yielded an average score of 72.8% (Good), indicating satisfactory conceptual and pedagogical quality, although improvements were recommended for language clarity. Practicality evaluation by two mathematics teachers produced an average score of 95.5% (Strongly Agree), demonstrating high classroom usability. These findings indicate that the cultural heritage of the Dayak Bumi Segandu Indramayu community can be systematically transformed into a valid and practical mathematics learning resource while contributing to the preservation of local knowledge through school mathematics.
