Introduction

Pengaruh pendekatan realistic mathematics education (rme) terhadap kemampuan pemecahan masalah matematis siswa kelas viii smp negeri 2 kabun. Pelajari pengaruh Pendekatan Realistic Mathematics Education (RME) terhadap kemampuan pemecahan masalah matematis siswa kelas VIII SMP. Penelitian ini membuktikan RME efektif tingkatkan kemampuan tersebut.

Abstract

This research was motivated by the low mathematical problem-solving abilities of class VIII students at SMP Negeri 2 Kabun. One solution to overcome this problem is to use Realistic Mathematics Education (RME) approach.This research aims to determine whether or not there is an influence between student who use the RME approach and student who use a conventional approach on problem solving abilities. This research is a quasi-experimental study using a posttest only design with nonequivalent group. The research subjects consisted of class VIII A, totaling 27 students and VIII B, totaling 27 students. The sampling technique used is random sampling. The data collection techniques used were observation sheets and mathematical problem-solving ability test questions. The results of this research can be concluded that the RME approach can influence the mathematical problem-solving abilities of class VIII students at SMPN 2 Kabun. This can be proven through the t test from the two groups, it was found that 2,00 with a significance level of α5%. Because the value of (6,94 2,00) then is rejected and is accepted

Review

This research addresses a highly relevant and persistent challenge in mathematics education: the low mathematical problem-solving abilities among students. The study's motivation to explore the effectiveness of the Realistic Mathematics Education (RME) approach as a potential solution is commendable, given RME's pedagogical foundations in linking mathematics to real-world contexts. By investigating its influence on Class VIII students at SMP Negeri 2 Kabun, the paper contributes valuable empirical data to the discussion on effective teaching methodologies for improving crucial mathematical skills in the Indonesian educational context. Methodologically, the study adopted a quasi-experimental design using a posttest-only with non-equivalent groups, comparing an experimental group (Class VIII A, n=27) taught using RME with a control group (Class VIII B, n=27) using a conventional approach. While the abstract mentions "random sampling" for subjects, the non-equivalent group design typically implies using pre-existing intact classes, suggesting the random element might pertain to the assignment of the teaching approach to these classes rather than individual student randomization. Data was collected through observation and a specific mathematical problem-solving ability test. The key finding unequivocally supports the RME approach, concluding it significantly influences students' problem-solving abilities, a result robustly demonstrated by a t-test where the calculated t-value (6.94) substantially exceeded the critical t-value (2.00) at a 5% significance level. The strength of this study lies in its clear focus, practical applicability, and the strong statistical support for its conclusion. However, the inherent limitations of a quasi-experimental design mean that causal inferences, while strongly suggested, cannot be as definitively established as with true experimental designs. Further details on the specific duration of the intervention, the mathematical topics covered, and a more explicit description of how "random sampling" was implemented within the non-equivalent group framework would enhance the methodological transparency and rigor. Despite these points, the research provides compelling evidence for RME's efficacy, offering practical implications for curriculum development and pedagogical practices aimed at boosting students' mathematical problem-solving capabilities.
