Analysis of the Effect of the Indonesian Realistic Mathematics Education Approach on the Mathematical Problem-Solving Ability of Grade 6 Students
Abstract
The Indonesian realistic mathematics education approach offers a solution by creating a collaborative learning environment based on contextual problems relevant to students’ experiences. The integration of local culture, namely Banjar traditional cakes, was chosen to make learning more meaningful and foster cultural appreciation. This study aims to analyze the effect of the mathematical problem-solving abilities of sixth-grade elementary school students through the application of the IRME approach. This study used a quasi-experimental one-group pretest-posttest design with 22 sixth-grade students at a public elementary school in Banjarmasin city, Indonesia as the sample. Data were collected through observation and pre- and post-tests. The results showed that the Indonesian realistic mathematics education approach was implemented very well, with a 92.11% implementation rate. The average post-test score of students increased to 71.91, which is considered good. There was a significant difference between the conditions before and after treatment using the Indonesian Realistic Mathematics Education approach, as indicated by a paired-samples t-test. The increase in problem-solving abilities, as measured by the N-Gain analysis, was in the moderate category (0.51). This means that the Indonesian realistic mathematics education approach affects the mathematical problem-solving abilities of sixth-grade elementary school students.
