The Effect of The Application of The Realistic Mathematucs Education (RME) Learning Model on Chritical Thingking Ability

Abstract

This research aimed to determine the effect of the Realistic
Mathematics Education (RME) learning model on students critical thinking
ability for systems of linear equations with two variabels material in class VIII at
SMP Negeri 3 Jerowaru for the academic year 2023/2024. Research with a
quantitative approach that uses a quasi-experimental design, the experimental
class learning using the RME learning model while the control class using direct
learning. The population in this study was 3 class VIII students. The samples
were taken using a simple random sampling technique, resulting in class VIII A
as the experimental class and VIII B as the control class. Data collection was
carried out using critical thinking ability test questions (posttest). From the
research results, it was found that there were differences between the
experimental class and the control class. Judging from the average score of the
experimental class 69.08 and the control class 58.40, this shows that the critical
thinking ability of the class whose learning uses RME is better than the class
whose learning uses direct learning. The effect size test results obtained were
0.69, which is in the medium category. So it can be concluded that there is an
effect of the RME learning model on students' critical thinking skills in SPLDV
material in class VIII of SMP Negeri 3 Jerowaru in the medium category.
