Abstract

The purpose of the study was to determine the effect of mathematical self-efficacy on mathematical reasoning abilities in online learning situations. The research design is quantitative descriptive on 75 students of class XI SMA Negeri in one of Mataram City State. The data collection is in the form of a mathematical reasoning ability test score consisting of 5 items, and a 20-point SEM questionnaire. Data analysis using simple regression. The results showed that there was a significant positive relationship between mathematical self-efficacy and students' mathematical reasoning abilities. The simple regression equation, namely: Y = 38.075 + 0.483X explains how students' mathematical reasoning abilities can be improved by increasing mathematical self-efficacy. Observation of other factors in the formulation of the regression equation is important for further research, considering that the results of these findings show that the correlation between mathematical self-efficacy and mathematical reasoning ability is only 14.8%.

Abstract

The ability to understand concepts is an ability that supports students' ability to solve problems. However, psychological factors in the form of mathematical self-efficacy and gender, which are factors influencing this ability, have not been investigated much. The purpose of this study was to determine the ability to understand concepts based on mathematical self-efficacy and gender in problem-based learning situations. The one-shot case study design was applied to 70 grade 8 junior high school students in one of the schools in Mataram City selected by the purposive sampling technique. Data collection uses a concept understanding ability test, a mathematical self-efficacy questionnaire, and gender categorization. Data analysis techniques used were the one-sample t-test and the Anacova test. The results of the study show that the PBL model can assist students in developing conceptual understanding skills. Subsequent findings state that mathematical self-efficacy and gender are factors that determine students' ability to understand concepts.
