Abstract

Students' mathematical understanding ability is often low, particularly on the Cartesian coordinate material, due to the lack of innovative learning media used in schools. This study aims to develop Kartematika, an Android-based learning media that is valid and practical for facilitating students' mathematical understanding. The research employs the 4-D development model, which includes the stages of Define, Design, Develop, and Disseminate. Data collection instruments include validation sheets and student response questionnaires, while data analysis techniques involve validity and practicality tests. Validation results show that the learning media achieved a validity level of 93.6%, categorized as highly valid. Practicality tests were conducted in two stages, yielding results of 91.4% (highly practical) in a small group trial and 89.6% (highly practical) in a large group trial. Based on the findings, the Android-based Kartematika learning media meets the criteria of validity and practicality, making it suitable for improving students' mathematical understanding on Cartesian coordinate material. This media is expected to serve as an innovative solution for mathematics learning in schools.

Abstract

This study aims to improve mathematics learning outcomes through the implementation of the Problem-Based Learning (PBL) model. The subjects of this study were students of class VIII-C at SMP Negeri 1 Kerumutan in the even semester of the 2024/2025 academic year, consisting of 17 male and 14 female students. The research instruments included learning tools and data collection instruments. The learning tools comprised the Learning Objectives Flow and Teaching Modules, while the data collection instruments consisted of observation sheets and mathematics learning outcome tests. Based on the analysis of students' learning outcomes, there was a significant improvement from the baseline score (before the action) to cycle I and cycle II. At the baseline, only 8 students (25.80%) achieved the minimum mastery criteria, which increased to 17 students (54.83%) in cycle I, and 19 students (61.29%) in cycle II. These findings indicate that the implementation of the Problem-Based Learning model effectively improves the learning process and enhances mathematics learning outcomes on statistics material in class VIII-C of SMP Negeri 1 Kerumutan during the 2024/2025 even semester.
