PENGARUH KECERDASAN NUMERIK DAN RASA PERCAYA DIRI TERHADAP PEMAHAMAN KONSEP MATEMATIKA

Abstract

This study aims to investigate: (1) the joint effect of numerical intelligence and self-confidence on students’ understanding of mathematical concepts in public junior high schools in Bekasi Regency, (2) the effect of numerical intelligence on students’ understanding of mathematical concepts, and (3) the effect of self-confidence on students’ understanding of mathematical concepts. The population consisted of 678 students from SMP Negeri 2 Cikarang Selatan and SMP Negeri 4 Cikarang Utara, with a sample of 87 students selected randomly. The research employed a survey method with a correlational technique. The results revealed that numerical intelligence and self-confidence simultaneously had a significant effect on the understanding of mathematical concepts, with Sig. = 0.000 < 0.05 and F-value = 84.500. The contribution of both variables together was 87.22%, while the remaining 12.78% was influenced by other factors not examined in this study. Partially, numerical intelligence had a significant effect with Sig. = 0.000 < 0.05 and t-value = 4.922, while self-confidence also had a significant effect with Sig. = 0.000 < 0.05 and t-value = 1.032. These findings emphasize that numerical intelligence and self-confidence are essential factors influencing students’ understanding of mathematical concepts in junior high schools.
