Abstract

The problem in this study is the low understanding of multiplication concepts in fourth-grade elementary school students caused by traditional learning practices (lecturing and memorization) that emphasize procedural outcomes rather than conceptual understanding. This study aims to determine the effect of the Contextual Teaching and Learning (CTL) learning model on students' understanding of multiplication concepts. Using a quantitative approach with a one-group pretest-posttest design, this study involved fourth-grade students of SDN Gili Timur 2 as subjects. Data were collected through test instruments (pretest and posttest) and analyzed using a paired sample t-test. The results showed an increase in the average score from 51.05 to 72.35. The results of the hypothesis test showed a calculated t value (7.006) > t table (2.093) and a significance level of 0.000 < 0.05, so H0 was rejected and Ha was accepted. It was concluded that the use of the CTL model had a significant effect on fourth-grade students' understanding of multiplication concepts.

Abstract

This study aims to determine the effect of using shell-based loose parts media on second-grade students’ numeracy skills in addition and subtraction material. The research used an experimental method with a pretest-posttest control group design. The results of the independent sample t-test on the pretest showed a Sig. (2-tailed) value of 0.637 and a t-value of 0.467, which is less than the t-table value of 2.026, with the average scores of the control class at 46.31 and the experimental class at 47.77. This indicates no significant difference between the two groups before treatment. However, the posttest results showed a Sig. (2-tailed) value of 0.000 and a t-value of 4.556, which is greater than the t-table value of 2.026, with average posttest scores of 47.36 for the control class and 72.22 for the experimental class. These findings indicate a significant difference after the treatment. Therefore, mathematics learning using shell-based loose parts media is proven effective in improving students’ numeracy skills.
