Abstract

This study aims to determine the improvement of mathematical representation ability and self-efficacy in ratio material among fifth-grade elementary school students using the Model-Eliciting Activities (MEAs). This research employs a mixed-method approach with a quasi-experimental nonequivalent control group design. The experimental group received treatment using Model-Eliciting Activities (MEAs), while the control group was taught using conventional learning methods. Data collection techniques in this study included tests, questionnaires, documentation, observation, and interviews. Data analysis consisted of descriptive analysis, prerequisite tests, and final analysis in the form of hypothesis testing (T-test, Z-test, mean difference test, and gain test). The results of this study indicate that Model-Eliciting Activities (MEAs) have a significant effect on the mathematical representation ability of fifth-grade students in the Sultan Agung cluster in ratio material. This is demonstrated by the analysis results using the paired sample t-test, which produced a t-value (t_calculated) greater than the t-table value (13.047 > 2.145). Model-Eliciting Activities (MEAs) are effective in improving students' mathematical representation ability, as shown by the independent sample t-test results, where t_calculated was greater than the t-table value (2.52 > 2.048). There is a significant difference in self-efficacy between students who received MEAs-based learning and those who received conventional learning. The analysis using the independent sample t-test showed that the t_calculated value for self-efficacy was 2.935, for the magnitude dimension was 2.522, for the strength dimension was 2.699, and for the generality dimension was 2.871. Given that the t-table value was 2.048, it can be concluded that the t_calculated values for the self-efficacy questionnaire results in the experimental and control classes, across the dimensions of magnitude, strength, and generality, were greater than the t-table value.
