Enhancing Mathematical Connection Ability through Scratch-Assisted Problem-Based Learning: A Mixed-Methods Study in Exponent Topics Annisa, Nurul Fadilah Sudihartinih, Eyus Usdiyana, Dian Luneta, Kakoma Mathematics Education This study aims to investigate the role of Scratch multimedia in enhancing junior high school students' mathematical connection skills related to the topic of exponents. This study employed a mixed-methods design, integrating quantitative and qualitative approaches, with 25 ninth-grade students as participants. Six students were purposively selected for in-depth interviews. Quantitative data were collected through pre-tests and post-tests and analyzed using paired-samples t-tests. In contrast, qualitative data were obtained from observation and interview results, and were analyzed thematically to identify the main themes during the learning process. Quantitatively, the study's results showed a significant increase in each indicator of mathematical connection skills. The indicator of connections between mathematical ideas (M post-test = 78.40, M pre-test = 45.20, t(24) = 7.43, p = 0.002) with an N-Gain value of 61% showed a fairly good increase. The connection indicator between mathematical representations (M post-test = 93.32, M pre-test = 58.40, t(24) = 4.89, p < 0.001) with an N-Gain value of 84% demonstrated a significant improvement. The connection indicator of mathematics with real-life problems (M post-test = 74.40, M pre-test = 24.20, t(24) = 6.18, p < 0.001) showed a significant improvement, with an N-Gain value of 61%, indicating a strong connection. Qualitatively, the study's results revealed three main themes: the use of Scratch multimedia in exponential learning enhances students' understanding of the material, creates a fun learning experience, and strengthens understanding through games. This study shows a positive impact of Scratch multimedia on improving students' mathematical connection abilities. Future research can utilize longitudinal studies to determine whether learning improvements are sustained in the long term.    Keywords: mathematical connection, mathematics learning, scratch multimedia.  FKIP Universitas Lampung 2025-11-14 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/800 10.23960/jpmipa.v26i4.pp2209-2223 Jurnal Pendidikan MIPA; Vol 26, No 4 (2025): Jurnal Pendidikan MIPA; 2209-2223 2685-5488 1411-2531 eng https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/800/613 https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/downloadSuppFile/800/158 https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/downloadSuppFile/800/159 https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/downloadSuppFile/800/160 https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/downloadSuppFile/800/162 https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/downloadSuppFile/800/163 Copyright (c) 2025 Nurul Fadilah Annisa, Eyus Sudihartinih, Dian Usdiyana https://creativecommons.org/licenses/by-sa/4.0
