Abstract

From the research results, there is data that the use of computers in learning is still limited to the use of powerpoint. Mathematics teachers still face difficulties in making learning media and teaching materials. The solution offered is to provide GeoGebra application training to mathematics teachers to assist them in the process of learning mathematics. The purpose of this activity is to increase teacher and student understanding of the role of mathematics learning media and increase the knowledge and skills of teachers and students about good and explorative virtual learning media (mathlet). The method that will be carried out in this activity is through several stages, namely direct observation, interviews, presentations, and question and answer. The result of this activity is that teachers can improve the quality of the learning process in accordance with the current digital era. and knowledge gained in training, teachers are more creative and innovative in creating learning processes, teachers have understanding and knowledge of virtual learning media, teachers can use the GeoGebra application to create virtual learning media, teachers can create visual media, teaching materials, and assessment instruments relating to algebra and geometry.

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.
