Abstract

This study evaluates the impact of developing a culturally grounded GeoGebra application on students' mathematical visual thinking abilities. Against the backdrop of a dearth of educational applications catering to local cultures, the research aims to address this gap. The methodology encompasses pre-test and post-test assessments, learning motivation surveys, classroom observations, and interviews with both students and educators. Data analysis reveals a significant enhancement in students' mathematical visual thinking abilities following the utilization of the application, accompanied by an upsurge in their learning motivation levels. These findings are corroborated by classroom observations and interviews, underscoring the application's role in augmenting student engagement and facilitating a more concrete understanding of mathematical concepts. The implications of this study underscore the significance of integrating culturally grounded educational technology to enhance the efficacy of mathematics education within the students' cultural contexts

Abstract

This study aimed to assess the difference in improving critical thinking and mathematical problem-solving abilities among students receiving cooperative learning with the TPS Square and TPS Share methods. The experimental method utilized a pretest-posttest control group design involving two groups of students from a secondary school. One group received instruction using the TPS Square method, while the other group utilized the TPS Share method. Research instruments comprised tests on critical thinking and mathematical problem-solving abilities. Data collected were analyzed using non-parametric statistical techniques. The results of the analysis revealed a significant improvement from the pretest to the posttest, as reflected in higher test scores in the final stage. Based on the t-test calculations, the critical value (t-table) at a significance level of 5% (α = 0.05) was found to be 2.514. With the computed t-value exceeding the critical value (2.157 > 2.514), it can be concluded that there is a significant difference in the average critical thinking and mathematical problem-solving abilities before and after instruction using the cooperative learning models TPS and TPSq among the students of grade XII at SMA Al Washliyah 1 Medan during the academic year 2022-2023.
