Abstract

This study is a systematic literature review aimed at describing various research findings related to students’ mathematical reasoning ability in relation to their self-efficacy levels. The method used is a systematic literature review by applying the keywords self-efficacy and reasoning ability, along with predefined inclusion criteria to select relevant articles. Articles that met the inclusion criteria were then analyzed qualitatively to draw valid and accountable conclusions. The results of the analysis reveal inconsistencies across studies regarding the influence of self-efficacy on students’ mathematical reasoning ability. Differences were also found in how varying levels of self-efficacy affect students’ performance in solving mathematical reasoning tasks. These discrepancies may stem from several factors, including sample limitations, differences in methodological approaches, the theoretical frameworks adopted, and variations in contextual field conditions. Therefore, further research is needed that involves more diverse variables and employs more comprehensive methodological designs to gain a more consistent and holistic understanding of the relationship between self-efficacy and students’ mathematical reasoning ability.

Abstract

Low student learning outcomes are a common problem found in the learning process. Learning models that are not yet varied are one of the causes of low student learning outcomes. This research aims to see the effect of the discovery learning model on the learning outcomes of class VII students at Bintang Langkat Junior High School. This research was carried out at Bintang Langkat Junior High School. The population in this study were all class VII students at Bintang Langkat Junior High School. The sample group was divided into 2 classes, namely the control class and the experimental class. Each class will be given a pretest and posttest. The instrument used was a multiplechoice test instrument with 20 questions. Before testing the hypothesis, the data was tested for normality and homogeneity. From the analysis results it was found that the samples were normally distributed and categorized as homogeneous. Next, a statistical hypothesis test can be carried out using the t test. The results of hypothesis testing with the t test show that H0 is rejected. So it can be interpreted that there is an influence of the use of the discovery learning model on the learning outcomes of Bintang Langkat Junior High School students.
