Abstract

This research aims to determine the effect of self confidence on student’s mathematical problem solving abilities. The population in this research was all eighth grade students of SMP Negeri 2 Sewon Bantul in the odd semester of the 2024/2025 academic year. The population in this study were all students in class VIII of SMP Negeri 2 Sewon Bantul for the 2024/2025 academic year. The sample in this research was class VIIIB which was selected using a purposive sampling technique. with a total of 29 students. Research data taken in the form of quantitative data obtained from self-confidence questionnaires and tests of student’s mathematical problem solving abilities. Based on the results of hypothesis testing using linear regression analysis obtained diperoleh nilai 0,501, sehingga persamaan regresi linearnya adalah Ŷ = 55,153 + 0,501X and correlation coefficient, it can be concluded that self-confidence has an effect on student’s mathematical problem solving abilities.
