Pengaruh Model Pembelajaran dan Disposisi Matematika Terhadap Kemampuan Pemecahan Masalah Matematika

Abstract

This research aims to investigate the influence of Learning Models and Mathematical Disposition on Mathematical Problem Solving Ability of high school students in the West Jakarta region. The research employed an experimental method, with data analyzed using a factorial 2x2 two-way analysis of variance (ANOVA). The population for this study consisted of tenth-grade students from two state high schools in West Jakarta. The sample consisted of 120 randomly selected students. The results showed: (1) Learning models had a significant effect on mathematical problem-solving ability (F=39.888;p=0.000). The average score of students in the Problem-Based Learning model group was 6.66, which was higher than the average score of students in the conventional learning model group. (2) Mathematical disposition had a significant effect on mathematical problem-solving ability (F=45.242;p=0.000). The average score of students with a high mathematical disposition was 47.15, whereas the average score of students with a low mathematical disposition was 43.60. (3) There was a significant interaction between the learning model and students' mathematical disposition level on their mathematical problem-solving ability (F=5.314; p=0.023).
