Abstract

This study aims to develop an ethnomathematics-based mathematical literacy instrument for elementary school students, which will be reviewed in terms of validity, reliability, level of difficulty, and discrimination power. The type of research used is Research and Development (R&D) with the Tessmer Formative Evaluation development model consisting of preliminary stages, self-evaluation, and prototyping stages (consisting of expert review, one-to-one, small group, and field test). The subjects of this study were 30 elementary school students. The data analysis techniques used were validity, reliability, difficulty level and discrimination power tests. The results of this study indicate that the ethnomathematics-based mathematical literacy instrument is valid based on the results of the expert review test. The reliability of the mathematical literacy instrument obtained a Cronbach's alpha value of 0.687. The mathematical literacy instrument's difficulty level was 40% for questions in the easy category and 60% for questions with a moderate level of difficulty. Meanwhile, from the results of the instrument difference test, 33% were in the weak category, 27% in the mild category, 33% in the good category, and 7% in the better category. The results of the development of mathematical literacy instruments based on ethnomathematics concluded that the test instrument met the eligibility criteria, namely meeting the elements of validity, reliability, level of difficulty and good discrimination so that it is suitable for use.

Abstract

This study aimed to test the effect of a case-based learning model with a local wisdom approach on students' mathematical reasoning. This type of research is quasi-experimental research with a nonequivalent control group design. The place of this research is at the University of Mataram, the PGSD study program. The population of the study was 300 students in the second semester, while the sample used in this study was 120 students selected using a random sampling technique. The research instrument used a mathematical reasoning test. The data analysis technique used normality and homogeneity tests as prerequisite tests, and independent sample t-tests for hypothesis testing and finally used the N-Gain test. The results of this study showed that the data were normally distributed and homogeneous. Then, from the results of the hypothesis test, the significance. (2-tailed) value was obtained of 0.04 <0.05 so that H0 was rejected and Ha was accepted, meaning that there was a significant difference between the average mathematical reasoning of students in the control group and the experimental group so that it was concluded that there was an effect of the case-based learning model with a local wisdom approach on students' mathematical reasoning abilities. Meanwhile, the N-Gain test results obtained a score of 0.45 with moderate criteria. This means that the case-based learning model with a local wisdom approach has a moderate level of influence on students' mathematical reasoning abilities.
