The objective of this investigation was to assess the efficacy of realistic mathematics education (RME) as a pedagogical approach for enhancing mathematical problem-solving proficiencies of students. The study employed an experimental research design utilizing a pretest and posttest design group. Two distinct classes were included in the study, with each class receiving different treatments. Data collection involved the utilization of an interest-in-learning questionnaire and a question test. The results of the hypothesis test indicated that the experimental class data exhibited significantly higher scores than the control class data on both measures of learning interest and test questions, with a two-tailed significance level of 0.000, 0.025 and 0.014, 0.025, respectively. This suggests that the RME-based mathematics learning flow is an effective approach for enhancing students' mathematical problem-solving abilities in class VIII SMP Negeri 1 Bangkinang.
