PENGARUH TEMAN SEBAYA DAN DISPOSISI MATEMATIK TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA
Abstract
The purpose of this research is to investigate: (1) the joint influence of peer relationships and mathematical disposition on students’ mathematical problem-solving ability, (2) the effect of peer relationships on mathematical problem-solving ability, and (3) the effect of mathematical disposition on mathematical problem-solving ability among vocational high school students in West Jakarta. This study employed a survey method with a sample of 90 students selected through simple random sampling. Data were collected using questionnaires and problem-solving tests, then analyzed through multiple linear regression. The findings reveal that peer relationships and mathematical disposition have a significant combined effect on students’ mathematical problem-solving ability, as evidenced by the regression test results (Sig = 0.000 < 0.05; F = 115.472). Furthermore, peer relationships significantly influence problem-solving ability (Sig = 0.000 < 0.05; t = 7.877), as does mathematical disposition (Sig = 0.000 < 0.05; t = 6.415). These results indicate that both peer interactions and positive mathematical dispositions play an essential role in enhancing students’ ability to solve mathematical problems. The study highlights the importance of fostering supportive peer environments and strengthening students’ mathematical disposition as a strategy to improve mathematical problem-solving skills.
