Abstract

This study aims to predict student achievement based on parental income and attendance. This study uses a quantitative approach with the population included all ninth grade students at SMP Swasta YP Utama Medan and the sample taken was 25 students. This study used instruments in the form of questionnaires and documentation. Data analysis used multiple linear regression to predict student academic achievement based on the variables of parental income and attendance. Prediction of students' achievement in grade IX at SMP Swasta YP Utama Medan based on parents' income and attendance patterns resulted in a Multiple Linear Regression equation that shows a positive relationship between economic conditions, students' attendance patterns and students' academic achievement. The accuracy level of prediction of student academic achievement based on parental income and attendance patterns shows that there are 16% of students getting excellent and 84% of students getting good grades

Abstract

The problem found is the low understanding of concepts on division operation material. This is due to the difficulty of understanding the abstract material. This is triggered by the lack of utilization of relevant learning media to overcome it. This study examines the effect of RME-based division machine props on the conceptual understanding of division among seventh-grade students at SMP Yayasan Perguruan IRA. This research design uses a pre-test and post-test control group as part of a quasi-experimental research method with a quantitative approach. The population of this study was all seventh-grade students, with a sample of 18 students in the control class and 18 in the experimental class. In the post-test, the control and experimental classes obtained sig <0.05, so it was stated that there was a significant difference between the experimental class and the control class. Thus, the study results showed a substantial effect in applying Realistic Mathematic Education (RME)-based division machine props on understanding the concept of division operations in class VII of SMP Yayasan Perguruan IRA. The findings highlight the practical effect of RME-based teaching aids in improving students' conceptual understanding and emphasize the need for scalable, inclusive teaching aids in mathematics education.
