Mathematical literacy is the ability to understand, use, and convey mathematical concepts in various contexts known as mathematical literacy. In Indonesia, the level of students' mathematical literacy skills is still low. This research aims to evaluate the validity and reliability of mathematical literacy test instruments using Rasch Model and SPSS. This research used a quantitative method with a survey approach involving 100 high school students from various demographic backgrounds, the instrument must be valid and reliable to ensure accurate measurement. The results of the analysis showed that the instruments tested has the same result which is invalid on item 5 and have good reliability of 0.639.

Abstract

This studynalyzes the effects of the CORE learning model on the mathematical representation abilities of junior high school students based on Field Independent (FI) and Field Dependent (FD) cognitive styles. Using a quasi-experimental methodology, this study involved 68 eighth-grade students from SMPN 169 Jakarta, divided into an experimental group using the CORE model and a control group with conventional learning. Study instruments included GEFT and mathematical representation ability tests. ANOVA analysis results indicate significant differences (F=48.655; p<0.05) between these groups, with the highest mean values in the FD experimental group (8.53), followed by the FI experimental group (7.84), FD control group (6.31), and FI control group (4.44). This study proves that the CORE learning model provides a significant effects in improving students' mathematical representation abilities, especially when combined with their cognitive styles.
