The Influence of the 'Earth Tells' Module Based on Ethnomathematics on the Mathematical Literacy Skills of Fifth Grade Elementary School Students

Abstract

The low level of mathematical literacy among elementary school students in Indonesia has become a significant problem in education, as mathematical literacy encompasses not only arithmetic skills but also logical thinking, problem-solving, and the application of mathematical concepts in everyday life. This research aims to examine the effect of using the ethnomathematics-based module 'Bumi Bercerita' on the mathematical literacy skills of fifth-grade elementary school students. A quasi-experimental method with a Nonequivalent Control Group Design was used, involving 55 fifth-grade students at SDN 106161 Laut Dendang, with 28 students in the experimental group and 27 in the control group. Data were analyzed using an independent sample t-test. The analysis results show a significance value of 0.007 (p < 0.05), indicating a statistically significant difference between the mathematical literacy outcomes of students in the experimental class and the control class. Therefore, the ethnomathematics-based module has been proven to be more effective in enhancing students' ability to formulate problems, apply concepts, interpret results, and evaluate solutions, as well as in fostering a more positive attitude towards learning mathematics.
