Abstract

Mathematics learning at SMA Negeri 1 Koto XI Tarusan was marked by teacher-centred explanation, limited digital teaching materials, and weak connections between mathematical ideas and students' experiences. Semester assessment records showed that 109 of 119 Phase F students, or 91.60%, had not reached the school minimum mastery criterion of 80. This study developed and examined the validity of an ethnomathematics-integrated mathematics e-module on systems of linear equations in two and three variables. The topics were selected as a gradual reinforcement of linear modelling from two variables to three variables, based on the school needs analysis. This Research and Development study used the 4D model. The article was limited to the define, design, and develop stages because the disseminate stage could not be carried out within the available research time. Three content experts, three design and graphics experts, and one language expert, assigned in accordance with institutional guidance, assessed the prototype. The validation results were 81.77% for content, 87.50% for design and graphics, and 86.36% for language. The combined score percentage was 84.47%, which falls into the highly feasible category. The e-module can proceed to practicality testing after revisions to conceptual accuracy, links between cultural contexts and mathematical models, information density, and sentence clarity.

Abstract

The low mathematics learning outcomes of Phase F students in the Computer and Network Engineering Department at SMK Negeri 5 Padang constitute one of the problems encountered in the learning process. This condition is characterized by low student participation, limited interaction and cooperation among students, a lack of confidence in asking questions, and a learning process that is still dominated by teacher explanations. This study aimed to determine whether the mathematics learning outcomes of students taught using the Think Pair Share cooperative learning model were better than those of students taught using conventional instruction. This study employed a quantitative approach with a quasi-experimental method. The population consisted of all Phase F students in the Computer and Network Engineering Department at SMK Negeri 5 Padang during the 2025/2026 academic year, totaling 57 students from two classes. The sampling technique used was saturated sampling, in which all members of the population were included as research participants. One class was assigned as the experimental class and received instruction using the Think Pair Share model, while the other class served as the control class and received conventional instruction. The research instrument was a mathematics achievement test in the form of essay questions that had undergone validation and pilot testing. The research data were analyzed using normality testing, homogeneity of variance testing, and a one-tailed independent-samples t-test. Because the data were normally distributed and homogeneous, hypothesis testing was conducted using the t-test. The results showed that >(4.24 > 1.68 at a significance level of α=0.05. Therefore, H₀​ was rejected and ​ H₁ was accepted. Based on these findings, it can be concluded that the use of the Think Pair Share cooperative learning model had a positive effect on the mathematics learning outcomes of Phase F students in the Computer and Network Engineering Department at SMK Negeri 5 Padang.

Abstract

Mathematics learning in Phase F requires students to understand abstract concepts, connect multiple forms of representation, and solve problems independently. However, preliminary observations at SMA Negeri 8 Padang showed that learning activities were still dominated by teacher explanations, the use of dynamic visual media was not optimal, and some students had difficulty understanding graph changes and the relationship between algebraic forms and geometric representations. This study aims to map teachers' and students' needs for mathematics learning through Project Based Learning (PjBL) supported by GeoGebra. The research employed a descriptive qualitative approach with an emphasis on needs analysis. The research context involved 116 Phase F students from three classes, consisting of 39 students in class XI F3, 40 students in class XI F7, and 37 students in class XI F9, as well as a mathematics teacher. Student interview informants were selected purposively. Data were collected through classroom observation, semi-structured interviews, and document study, then analyzed through data condensation, data display, and conclusion drawing and verification. Data credibility was maintained through technique and source triangulation. The findings identified five key needs: more participatory and contextual learning, dynamic visual media to clarify concepts, systematically structured project activities, learning tools and assessment instruments that are practical for teachers, and technology-use strategies that consider device availability and students' initial abilities. These findings indicate that GeoGebra-assisted PjBL is relevant to be developed as an alternative mathematics learning design, although its effectiveness still needs to be tested in further research.
