The Exploration of APOS-based PBL Model to Improve the Students’ Mathematics Problem-Solving Skills Rahayu, Ratri Kartono, Kartono Agoestanto, Arief Math majors must be excellent problem solvers because problem-solving is the foundation of teaching mathematics. Their problem-solving skills will help them create service initiatives as math teachers. This research investigated how well the APOS-based PBL model enhances students' skills in solving mathematical problems. This quasi-experimental design used a non-equivalent post-test-only control group, which is quantitative. Students at a university in Central Java, Indonesia, participated in the study. Tests of problem-solving skills were useful to collect the data. The results of the study showed that (1) students' problem-solving skills lead to learning completion (71); (2) students taught using a modified PBL model based on APOS theory have a different proportion of learning completeness than students taught using an average class using a direct learning model; (3) students' average problem-solving skills taught using the modified PBL model based on APOS theory are superior to those taught in the average class using a direct learning model; (4) increasing students' problem-solving skills taught using a modified PBL model based on APOS theory is preferable to improving students' skills taught using a direct learning model. This study offers insightful insights into the PBL model's implementation, incorporating APOS theory at every stage. These results suggest that to maximize students' problem-solving skills, consideration of the theory of thinking processes must be given when putting the learning model into practice      Keywords: APOS, mathematics, PBL, problem-solving skills.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1577-1592 FKIP Universitas Lampung 2025-01-01 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/136 Jurnal Pendidikan MIPA; Vol 25, No 3 (2024): Jurnal Pendidikan MIPA; 1577-1592 2685-5488 1411-2531 eng https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/136/113 Copyright (c) 2025 Ratri Rahayu, Kartono Kartono, Arief Agoestanto https://creativecommons.org/licenses/by-sa/4.0
