Abstract

Purpose of the study: This research aims to determine the relationship between parental education level and student learning achievement and between the role of parents and student learning achievement which was carried out at State Elementary Islamic School 1 South Tangerang. Methodology: This research uses a correlational quantitative approach. The sample to be studied is 36 students. The sample used in this research, the author used a Nonprobabillity Sampling technique, Saturated Sampling/Census type. this research uses data collection methods in the form of documentation and distributing questionnaires. The data analysis techniques used in this research are descriptive analysis and parametric statistical analysis. Main Findings: The results of this study show that there is a positive and significant relationship between the level of parental education and the learning achievement of class V Madrasah Ibtidaiyah Negeri 1 South Tangerang City students with a correlation coefficient of 0.357. And there is also a significant positive relationship between the role of parents and the learning achievement of class V Madrasah Ibtidaiyah Negeri 1 South Tangerang City students with a correlation coefficient value of 0.359 Novelty/Originality of this study: This study provides a new perspective that the combination of parents' high level of education and their active involvement in their children's education is a stronger determining factor in improving mathematics achievement than other factors.

Abstract

Purpose of the study: This study aims to obtain population growth prediction results using the Adams-Bashforth-Moulton method. Methodology: This type of research is applied research. In this study, the Adams-Bashforth-Moulton method was applied by solving the problem of population growth in South Sulawesi Province. Main Findings: The logistic equation for population growth with a step size of h = 1 and the capacity of South Sulawesi Province is 20,000,000 people, with a growth rate of 2%. The numerical solution of the logistic equation for population growth at time t = 2020 with an optimal step size of ℎ = 1 is 8,944,168 people. Novelty/Originality of this study: This research is unique in the form of applying the Adams-Bashforth-Moulton method to solve problems in calculating population growth in South Sulawesi Province.

Abstract

Purpose of the study: The aim of this research is to improve students' learning outcomes in Mathematics by using the Problem Solving method. Methodology: The research conducted used Classroom Action Research. Data were obtained from qualitative and quantitative data. Data collection techniques included observation, testing, documentation, and interviews. The data analysis method used both qualitative and quantitative data. Main Findings: Based on the results of data analysis, it is known that, after using the Problem Solving method, student learning outcomes have increased. This can be seen from the results of the pre-test and post-test given to students, which always increased in each cycle. The increase in student learning outcomes in cycle 1 was 71.88% and in cycle II 87.10%. There was an increase in the completeness of student learning outcomes by 5.31%. Novelty/Originality of this study: This study introduces a structured problem-solving instructional model implemented through classroom action research to regularly improve students' mathematics learning outcomes. Unlike previous studies, it integrates iterative reflection cycles with authentic classroom problems, providing practical evidence on how problem-solving instruction directly enhances students' engagement, conceptual understanding, and achievement.
