Abstract

This study aims to determine the improvement between the Realistic Mathematic Education model and the conventional learning model on students' Mathematical Reasoning abilities with the material of Curved Side Space Buildings. This type of research is quantitative, and the research techniques used in this study are observation, testing, interviews and documentation. Based on the results of data analysis and pretest posttest data hypotheses, the average posttest value of the experimental class can be obtained at 0.738, the average posttest of the Control class is 0.039, so there is an increase in the Realistic Mathematic Education learning model on students' mathematical reasoning abilities using Quiziz. This is evidenced by the results of the t-test obtained tcount> ttable, namely (0.000> 0.05). This means that there is a difference in the average mathematical reasoning ability of students before and after using the Realistic Mathematic Education learning model. The pretest Normality Test shows that the sig. value is 0.993> 0.05. While the pretest Homogeneity test shows a sig. value of 0.395> 0.05. The results of the data analysis test in the form of pre-test data hypothesis testing, showed that both sample classes had the same initial ability regarding students' Mathematical Reasoning abilities.

Abstract

This study aims to analyze the effect of the Teaching Factory (TEFA) learning model assisted by the Desmos application based on Batak Toba local wisdom on students’ mathematical problem-solving abilities. The research employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The subjects were eleventh-grade science students of SMA Muhammadiyah 7 Serbelawan, consisting of an experimental class and a control class with 38 students each. The experimental class was taught using the TEFA model assisted by Desmos integrated with Batak Toba cultural contexts, while the control class applied a scientific learning model based on local culture. The research instrument was a mathematical problem-solving ability test that had been validated and tested for reliability. Data analysis included normality testing, homogeneity testing, independent sample t-test, and N-Gain analysis. The results indicated that students taught using the TEFA model assisted by Desmos achieved higher problem-solving abilities than those in the control class, with mean posttest scores of 90.34 and 85.94, respectively. The t-test results showed a t-value of 3.925, exceeding the t-table value of 1.993, with a significance level of 0.000 < 0.05. Furthermore, the N-Gain value of the experimental class was 0.81, categorized as high. These findings indicate that the Teaching Factory learning model assisted by the Desmos application based on Batak Toba cultural wisdom has a significant and positive effect on improving students’ mathematical problem-solving abilities.

Abstract

This study aims to examine the effect of using student worksheets (LKPD) integrated with Nusantara ethnic culture on students’ mathematical numeracy skills through the SAVI (Somatic, Auditory, Visual, and Intellectual) learning model. This research employed a quantitative approach using a true experimental design with a Post-test Only Control Group Design. The participants were eleventh-grade students of SMA Nurul Iman Tanjung Morawa in the 2025/2026 academic year, who were randomly assigned into an experimental class and a control class. The experimental class was taught using culturally integrated LKPD through the SAVI learning model, while the control class received conventional instruction. The research instrument consisted of an essay-type mathematical numeracy test that had been validated by experts. Data were analyzed using normality tests, homogeneity tests, and an independent samples t-test at a 0.05 significance level. The results indicated that the average mathematical numeracy score of students in the experimental class was higher than that of the control class. Hypothesis testing revealed a significance value lower than 0.05, indicating a statistically significant difference between the two groups. These findings demonstrate that the use of LKPD integrated with Nusantara ethnic culture through the SAVI learning model has a positive and significant effect on improving students’ mathematical numeracy skills. Therefore, culturally integrated worksheets can serve as an effective contextual learning alternative to enhance students’ mathematical numeracy abilities.
