PENGARUH MODEL RME BERBASIS ETNOMATEMATIKA BERBANTUAN GEOGEBRA TERHADAP KEMAMPUAN PEMECAHAN MASALAH SISWA

Abstrak

The purpose of this study is to determine the effect of the Realistic Mathematic Education (RME) learning model based on ethnomathematics assisted by the GeoGebra application to improve students' mathematical problem-solving abilities. This study used a quantitative method with a Design Pretest-Posttest Control Group. This study is conducted at SMP Negeri 2 Kisaran. The research are taken from 2 classes, that is VIII-1 class consiststs of 60 students, as an experimental class and was taught using Realistic Mathematic Education (RME) , learning models based ethnomathematic assisted by the Geogebra aplication and VIII-2 class that consists of 30 students, as the control class, tought using the direct learning model. Both classes uses a quasi eskperiment technique. The instrument used is a problem-solving ability test instrument consisting of 5 summary questions. The data obtained in this study are in the form of students' mathematical problem-solving ability scores analyzed by t-test. Based on the data obtained, it is known that the average value of the mathematical problem-solving ability of students in the experimental class is higher (82.46) than the control class (76.53). The results of the hypothesis calculation obtained,  it is  rejected and  accepted. Based on the results of the data analysis, it is found that there was an influence of the Realistic Mathematic Education (RME) learning model based on ethnomathematics assisted by the GeoGebra application to improve students' mathematical problem-solving abilities in UPTD SMP Negeri 2 Kisaran.
