Abstract

This study aims to create and test the quality of a math e-module that incorporates ethnomathematics to improve students' mathematical literacy. This is a development study that follows the ADDIE development model, which includes five stages: analyze, design, development, implementation, and evaluation. The research involved 25 students. The findings showed that the experts rated the e-module at an average score of 80.2%, which is considered valid. The e-module was also found to be very practical based on the student questionnaire score of 89.72%. Its effectiveness was proven with 100% of students achieving over 85% in the mathematical literacy test. Based on these results, it can be concluded that the developed ethnomathematics-based math e-module for the topic of systems of linear equations in two variables is suitable to be used as a learning material.

Abstract

This study aims to determine the effectiveness of the cooperative learning model Student Teams Achievement Division (STAD) on the mathematics learning outcomes of eighth-grade students at SMP Negeri 1 Halongonan. The background of this research is the low mathematics learning outcomes of students, which are caused by a lack of conceptual understanding, low learning motivation, and the perception that mathematics is a difficult subject. This research employed an experimental method with a One Group Pretest-Posttest Design. The research subjects consisted of 18 eighth-grade students at SMP Negeri 1 Halongonan. The research instruments included a learning outcome test and an observation sheet for learning activities. Data were analyzed using normality, homogeneity, and t-tests with the aid of SPSS version 27. The normality test results indicated that the data were normally distributed, with significance values of 0.200 > 0.05 for the pretest and 0.174 > 0.05 for the posttest. The homogeneity test showed a significance value of 0.149 > 0.05, indicating that the data were homogeneous. The average student learning outcome before applying the STAD model (pretest) was 49.83, while after its application (posttest), it increased to 83.39. The t-test results showed a significance value of 0.000 < 0.05, meaning that H₀ was rejected and Hₐ was accepted. This indicates a significant difference between students’ learning outcomes before and after implementing the STAD model. The correlation value between the two variables was 0.248, showing a positive relationship between the implementation of the STAD model and the improvement of students’ mathematics learning outcomes. Based on these results, it can be concluded that the cooperative learning model of the STAD type is effective in improving the mathematics learning outcomes of eighth-grade students at SMP Negeri 1 Halongonan.

Abstract

This study aims to determine the effectiveness of the Discovery Learning model using the Board Elements of Circle (BEC) teaching aid on students’ critical thinking skills in the topic of circles at MTs N 2 Padangsidimpuan. This research employed an experimental method with a non-equivalent control group design. The subjects of the study consisted of two classes, namely class VIII-6 as the experimental group and class VIII-5 as the control group, each consisting of 16 students. The research instrument was a critical thinking skills test that had been validated and tested for reliability. Data were analyzed using normality tests, homogeneity tests, and t-tests with the help of SPSS 27 software. The results showed that the data were normally distributed with an Asymp. Sig (2-tailed) value of 0.200 > 0.05, and homogeneous with Sig. values of 0.315 > 0.05 for the experimental class and 0.198 > 0.05 for the control class. The average pretest score of the experimental class was 48.8 (poor category), which increased to 89.3 (excellent category) in the posttest. Meanwhile, the control class had an average pretest score of 52 (poor category) and a posttest score of 82 (good category). The t-test results indicated a correlation value between the two variables of 0.156 with a significance level of 0.039 < 0.05, which means that Ha is accepted and Ho is rejected. Therefore, it can be concluded that the Discovery Learning model using the Board Elements of Circle (BEC) is effective in improving students’ critical thinking skills on the topic of circles at MTsN 2 Padangsidimpuan.
