Abstract

This study aims to determine whether the mathematical representation ability of students taught using the Student Facilitator and Explaining (SFE) learning model with LKPD media is better than that of students taught using the direct instruction model at SMPN 7 Mataram. The research method used is a quasi-experimental design with a posttest-only control group design. The population consisted of eighth-grade students at SMPN 7 Mataram, with the sample comprising 42 students from class VIII-J as the experimental group and 42 students from class VIII-I as the control group, selected through purposive sampling. The experimental class was taught using the SFE learning model, while the control class received direct instruction. Data were collected through a mathematical representation ability test. The results of the t-test showed that ​, namely 7.04002 > 1.664, indicating that  was accepted. This means that the average mathematical representation ability of the experimental class was higher than that of the control class. Based on these results, it can be concluded that students who received instruction using the SFE model had better mathematical representation abilities compared to those who received direct instruction.

Abstract

This study was motivated by the low mathematical problem-solving ability of students, which is attributed to the use of ineffective, teacher-centered learning models. One approach that can be applied to improve students’ mathematical problem-solving skills is the problem-based learning (PBL) model. This study aims to determine the effect of implementing an ethnomathematics-based problem-based learning model on students’ mathematical problem-solving ability. The research was conducted at SMP Negeri 14 Mataram in the 2024/2025 academic year using a quantitative approach with a quasi-experimental design. The population consisted of all eighth-grade students at SMP Negeri 14 Mataram. The research sample comprised 60 students, with 30 students in the experimental class and 30 in the control class, selected through simple random sampling. The data collection instrument was a mathematical problem-solving test. The average score of the experimental class was 77.70, which was higher than the control class’s average score of 71.40. The analysis results showed that . Furthermore, the effect size calculation yielded d = 0.69, indicating a moderate effect. These results show that the ethnomathematics-based problem-based learning model positively influences the mathematical problem-solving ability of eighth-grade students at SMP Negeri 14 Mataram, particularly in the topic of circles.
