Abstract

The use of e-modules in mathematics learning significantly aids both teachers and students in the teaching and learning process. However, the design of e-modules has not been extensively linked to the cultural context in which students live. Therefore, this study aims to explore and analyze the needs of teachers and students in developing culturally integrated e-modules, particularly those reflecting the culture of Papua, for high school students. The research design employed is phenomenological. Participants included Mathematics teachers for grades X, XI, and XII in Nduga Regency, Papua Highlands, and 64 high school students (42 male and 22 female). Data collected from observations and interviews were qualitatively analyzed using Miles-Huberman Interactive Analysis. Findings revealed that the high schools still use the 2013 curriculum, relying on standard textbooks as teaching materials. These textbooks pose problems for students as they are often uninteresting, use formal language, are difficult to understand due to abstract content, and are not contextualized to students' daily lives. Additionally, the reduction in face-to-face learning hours, due to the school's location in a conflict area, hampers effective teaching and learning processes. Another interesting finding is that high schools in Nduga Regency have not yet utilized technology in learning, despite having internet access. These findings imply the need for teaching materials integrated with technology and local culture to help students understand mathematics concepts and assist teachers in teaching both inside and outside the school.

Abstract

Mathematics is a subject rich in representations, ranging from tables, diagrams, symbols, physical, to verbal. In the realm of mathematics, students are required to master all of these types of representations. To facilitate learning encompassing all of these representations, various structured materials and references are necessary. The objective of this research was to determine the extent of improvement in mathematical representation among students who received Model Resource-based Learning aided by Google Classroom. The research method employed was quasi-experimental. Sample of this study were students of grade XI in the academic year 2021/2022 at one high school in Bandung. Purposive sampling technique was used for sample selection. The research sample was selected based on available classes, ensuring that both classes had equivalent initial capabilities. One class then became the experimental group, while the other class served as the control group. The research instrument was a test of mathematical representation ability. Based on the data analysis, the improvement in mathematical representation ability among students in the experimental group was higher compared to students in the control group. It was also found that despite being provided with resources in Google Classroom, students' verbal representations were still lacking and remained the lowest type of representation besides physical representation.
