This study aims to identify the factors influencing the academic achievement of mathematics education students at Nias University. The researcher employed the CHAID method to address this research problem. Data was collected through an online survey distributed to Mathematics Education students from the 2020 to 2023 cohorts who were in their second to eighth semesters. The analysis results indicate that both the type of residence and gender significantly influence students' academic achievement. The analysis revealed that students who chose to live in dormitories or with their parents significantly obtained higher Grade Point Averages (GPAs) compared to those who chose to live with guardians or in rented accommodations. The findings of this study can be utilized to design more effective intervention programs to enhance students' academic achievement, particularly for those who choose specific types of residence. A deeper understanding of the factors influencing academic achievement is expected to serve as a foundation for efforts to improve the quality of education at Nias University..

Early studies show that: (1) students' mathematical abilities are in the category of lacking; and (2) The learning process still does not utilize technology in an integrated manner. Therefore, LKPD was developed using a liveworksheet to overcome these problems. The purpose of this research is to develop a valid, practical and effective LKPD to improve students' mathematical problem-solving skills. This research uses the ADDIE (analyze, design, development, implementation, evaluation) development model. The instruments in this study are learning outcome tests, material expert validation questionnaires, linguist validation questionnaires, media expert validation questionnaires, teacher response questionnaires and student response questionnaires. Based on the results of the research, the LKPD developed has been tested and declared valid both in terms of material validity, language validity and media validity. Furthermore, the LKPD is also very practical based on the results of the teacher response questionnaire and the student response questionnaire. The LKPD developed is also effective in improving students' mathematical problem-solving skills, as seen from the test scores of student learning outcomes. Thus, it can be concluded that LKPD using the liveworksheet developed has met the expectations or objectives of the research.

This research was motivated by students' low mathematics learning outcomes at one of the State High Schools in Umbunasi. The primary purpose of this study is to analyze the relationship between character education and mathematics learning outcomes. This study uses a quantitative approach with an associative descriptive method emphasizing the cause-and-effect relationship. The research design applied is correlational. The research subjects comprised 24 students in grade XII-Science at the State High School. The instruments used to collect data include observations, questionnaires, tests, interviews, and documentation. The study results showed that the questionnaire and test data were normally distributed. The hypothesis test using the t-test produced a local value = 603, more significant than the ttable value = 1.717, which means that the null hypothesis (H0) was rejected, indicating a significant relationship between character education and mathematics learning outcomes. The results of the product-moment correlation test showed a calculation value = 0.700, more significant than the table = 0.404, which showed a strong relationship between the two variables and the contribution of character education of 49.06% to mathematics learning outcomes.

Learning processes and daily life are significantly influenced by reasoning ability. Specifically, in mathematics education, reasoning is crucial for students to master. Reasoning plays a vital role in the development of mathematical thinking, serving as a foundation that enables students to delve into and understand general mathematical concepts and to draw conclusions from mathematical problems. By applying a problem-based learning model, students can be assisted in solving mathematical problems related to current issues. This study uses a qualitative approach with a phenomenological perspective, aiming to analyze and describe students' mathematical reasoning abilities through the problem-based learning model. The research was conducted at SMP Negeri 4 Gunungsitoli Utara. The results showed that after the reasoning ability test, student scores varied, with the highest score being 87, the lowest 31, and an average of 63.35, categorized as moderate. The analysis identified several factors affecting students' reasoning abilities, including lack of conceptual understanding, inconsistency in problem identification, lack of precision, and difficulty in finding formulas to solve problems.
