Abstract

This study aims to reveal the counting patterns performed by Indramayu Traditional Market Traders in buying and selling activities. This research uses a qualitative approach with a descriptive case study design. The sampling technique used was purposive sampling by collecting data using snowball sampling. The participants involved in this study were three traders. Data analysis in this study used qualitative analysis from Milles & Huberman, which consisted of 4 stages: data collection, data reduction, data presentation, and conclusion. The results of this study indicate that Indramayu traditional market traders have used mathematical concepts such as addition, subtraction, multiplication, and division operations in buying and selling activities. Besides that, this study also found that traditional traders use backward calculations (from front to back) in buying and selling their wares. The calculation method traditional trader’s use differs from that usually taught in schools. This method has become a standard pattern to make it easier for them to count. Based on these findings it implies that there are other ways of operating information activities that can be used by schools formally. In addition, teachers must be able to provide the context in everyday life, especially in buying and selling activities in traditional markets, to students so that students get a broader understanding of solving problems in arithmetic material.

Abstract

Using e-modules in learning has improved students' mathematical problem-solving abilities. However, the design of e-modules that integrate local culture is still rarely developed. This study aims to create a contextual e-module that reflects the culture of the Papuan community at State Vocational School I Agribusiness and Agrotechnology Nduga. This study used research and development (R&D) methods with the ADDIE model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The participants in this study included material, language, media experts, teachers, and eleventh-grade students. Qualitative data were collected through respondent suggestions, and quantitative data were obtained through validation questionnaires and student testing. The analysis results showed that the Papuan cultural contextual e-module was valid, with percentages of 77.33% from material experts, 73.33% from language experts, and 68.88% from media experts. Teacher and student responses showed excellent practicality, with averages of 93.33% from teachers and 85.28% from students. In addition, the pre-test and post-test results showed a significant improvement in students' mathematical problem-solving abilities, with the KKM achievement level reaching 95.5% and a significance value (Sig. 2-tailed) < 0.001. Therefore, the contextual e-module based on Papuan culture can be an effective supplementary teaching material in mathematics learning, especially in linear programming material.

Abstract

Students’ spatial visualization ability is a key component in understanding geometry, yet many students exhibit suboptimal performance in this area. This study aimed to (1) evaluate the quality of the Geogebra-assisted 6E-IM learning model, (2) examine its effect on students' spatial visualization ability, and (3) describe students' ability levels after receiving the intervention. A sequential explanatory mixed-methods design was used. The independent variable was the Geogebra-assisted 6E-IM model, while the dependent variable was students’ spatial visualization ability. A total of 60 students participated, with 30 assigned to the experimental group and 30 to the control group. Data were collected through tests, interviews, and questionnaires. Quantitative results showed that students in the experimental group significantly outperformed the control group (p < 0.05), indicating a positive effect of the Geogebra-assisted 6E-IM model on spatial visualization ability. Qualitative analysis revealed that students with high ability met all spatial visualization indicators; those with moderate ability met two indicators, while those with low ability met only one. These findings demonstrate that the integration of Geogebra in the 6E-IM learning model can effectively enhance students’ spatial visualization skills in geometry. This study contributes to the development of innovative, technology-integrated instructional strategies in mathematics education.
