Abstract

This study examines the influence of the Problem Based Learning (PBL) learning model on the problem solving ability and mathematical disposition of grade X students of the Private Aviation Vocational School of Berayan Island Darat Medan. Using a quasi-experimental approach with two groups, namely the experimental group taught using the PBL model and the control group taught using conventional learning, this study aims to analyze the effectiveness of PBL in improving students' problem solving skills and mathematical disposition. Data was collected through problem solving ability tests (pretest and posttest) and mathematical disposition questionnaires during the even semester of the 2024/2025 school year. The results of the two-track ANOVA analysis with a significance level of 0.05 showed that the PBL learning model had a significant influence on students' problem solving ability (F=13,669; sig.=0.000<0.05). In addition, the mathematical disposition of students was also significantly influenced by the PBL model (F=17.041; sig.=0.000<0.05). However, this study did not find any interaction between the PBL learning model and mathematical early ability (KAM) in influencing problem solving ability (F=2.114; sig.=0.131>0.05) or students' mathematical disposition (F=0.454; sig.=0.637>0.05). This indicates that the PBL model exerts influence independently without being influenced by the student's KAM. These findings suggest that PBL models can effectively improve students' problem solving abilities and mathematical dispositions, regardless of their initial ability level, as well as provide a more engaging and meaningful learning experience in mathematics learning.

Abstract

Based on the results of initial observations at SMP Negeri 40 Medan, there are teachers who have not maximized the design, development, and utilization of learning media, especially flipbook media that has never been implemented. As well as the mathematical literacy skills and learning motivation of students are still low. This study aims to (1) produce flipbook media based on the Problem Based Learning learning model that is valid, practical and effective, (2) analyze the improvement of mathematical literacy skills and (3) analyze the improvement of student learning motivation using flipbook media based on Problem Based Learning. This study uses the ADDIE model. This study involved class VIII students of SMP Negeri 40 Medan. The instruments used in the development of flipbook media are Teaching Modules, LKPD, Mathematical Literacy Ability Tests and Student Learning Motivation Questionnaires. The results of the study are that the flipbook media meets the valid criteria with a score of 4.69, then the flipbook media was tested to obtain practical and effective media so that it meets the practical criteria with a score of 88.95, and the flipbook media meets the effective criteria with a score of 87.79. The increase in mathematical literacy skills measured by N-gain on the development trial conducted twice against pretest with posttest I with an average N-gain of 0.33 in the medium category, then against posttest I and posttest II with an average N-gain of 0.73 in the high category. Furthermore, the increase in students' learning motivation by measuring the pretest and posttest with an average N-gain of 0.6 in the medium category. Based on the N-gain results, it is stated that flipbook media based on the Problem Based Learning learning model is able to improve students' mathematical literacy skills and learning motivation at SMP Negeri 40 Medan.
