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.

Abstract

The use of learning media is still limited, making students tend to be more passive during the learning process. At SMA Negeri 1 Suwawa, the learning process predominantly uses textbooks, whiteboards, LKPD, and sometimes PowerPoint. These limitations make it difficult for students to understand the material, including mathematics lessons on the material of the System of Linear Equations of Three Variables (SPLTV) which requires image visualization. With the existing problems, research was conducted by utilizing technology which aims to develop mathematics learning media using the Sparkol VideoScribe application on SPLTV material which was carried out involving 20 class X students at SMA Negeri 1 Suwawa in June. This type of research uses the Research and Development (R&D) method using the four-D development model, namely Define, Design, Develop and Disseminate. Data analysis was carried out based on expert assessments, teachers, and student responses using a Likert scale. The development assessment was carried out based on the results of three media validators as well as learning materials and obtained validation results of 77% for media and 82% for materials with criteria worth using. The results of teacher and student responses obtained an average total percentage of 98% and 85% respectively which indicates that the media used meets practical criteria. For further research, it can develop learning media that attract more students' attention in learning activities and increase the activeness of students in learning activities, especially math lessons on SPLTV material.
