Abstract

This research aims (1) to describe the level of validity of mathematics learning media using Geogebra on the Cartesian Plane material, (2) to assess the mastery level of teachers and the students' engagement using Geogebra on the Cartesian Plane material, and (3) to explore educators' and students' responses to the development of mathematics learning media using Geogebra on the Cartesian Plane material at SMP Negeri 2 Pematang Siantar. The research design employed is Research and Development, following the ADDIE model consisting of Analysis, Design, Development, Implementation, and Evaluation. Based on the material validation results, it falls into the highly valid category with an average of 60.5, situated in the interval 54.6 ? VR < 65. Similarly, media validation is deemed valid with an average of 82, falling within the interval 68 ? VR < 84. The validated learning media was then implemented in the teaching process. Data analysis revealed that the teacher's mastery level averaged 92, categorized as practical within the interval 74.8 ? PR < 92.4. Additionally, during the trial, the students' engagement level averaged 47, falling in the interval 44.2 ? P < 54.6. The effectiveness of the developed learning media is evidenced by the students' achievement in the eighth-grade class at SMP Negeri 2 Pematang Siantar. Out of 30 students, 25 students achieved a passing grade with a percentage of 83.4%, while 5 students did not pass, constituting 16.6%. The developed learning media meets practical criteria, receiving highly positive responses from students with an average response rate of 94.97% and positive feedback from teachers with an average response rate of 82%.

Abstract

This research aims to determine whether there is an influence of the Problem Based Learning (PBL) instructional model on the mathematical problem-solving abilities of seventh-grade students at SMP Negeri 7 Pematang Siantar. The study employs a quantitative method, specifically a one-shot case study design. The population consists of all seventh-grade students at SMP Negeri 7 Pematang Siantar for the academic year 2023/2024, totaling 288 students. Cluster Random Sampling was used to select a sample, and one class, namely VII-1, was chosen for the study, resulting in a total sample size of 30 students. Data were obtained through a questionnaire measuring students' perceptions of the Problem Based Learning model and a mathematics problem-solving ability test for seventh-grade students at SMP Negeri 7 Pematang Siantar. The instruments utilized included 12 closed-ended statement questionnaires with Likert scale measurements and 5 mathematics problem-solving ability test questions. Following calculations, the conclusion drawn from the simple linear regression analysis with the equation Y’ = a + bX = 27.228 + 0.234X is that the calculated t-value (4.196) exceeds the critical t-value (2.042) at a significance level of 0.00 < 0.05. Consequently, the null hypothesis H0 is rejected, and the alternative hypothesis H  is accepted. The influence of the Problem Based Learning instructional model on the mathematical problem-solving abilities of seventh-grade students at SMP Negeri 7 Pematang Siantar is 38.6%. This implies that the Problem Based Learning model can affect students' mathematical problem-solving abilities by 38.6%, while the remaining 61.4% can be influenced by other factors
