Abstract

This study aims to identify significant differences between students who actively use social media and those who do not in the Faculty of Science and Technology at UIN Sumatera Utara, determine distinguishing variables between the two groups, develop a two-factor discrimination model, and test the model's accuracy. The study sampled 1,800 students from 220 study programs, with data collected through a questionnaire. The credibility and validity of the questionnaire were tested using SPSS with Wilk's Lambda and F-test. Discriminant analysis was employed to identify distinguishing variables, such as access, photo uploads, status updates, link sharing, and live stories, and to determine the membership proportions of each group. The results indicate significant differences in behavior between active and inactive social media users, with cross-validation showing a classification accuracy of 77.0%. These findings provide valuable insights into social media usage patterns among university students.

Abstract

The purpose of this study is to explore the role of philosophy in the in-service professional education program, batch 3, when viewed from the study of ontology, epistemology, and axiology. This type of research is qualitative research. This research method uses a case study method. The role of teachers in the education system is very important, not only as a transmitter of knowledge but also as a shaper of students' moral and ethical character. Teachers are required to continue to develop their competence to become professionals, per Law of the Republic of Indonesia Number 14 of 2005 which mandates academic qualifications, competence, certification, and physical and mental health. The Teacher Professional Education Program (PPG) aims to ensure that teachers have the required competence. This program is divided into pre-service PPG and in-service PPG, which are intended for teachers who are already actively teaching. This study focuses on in-service PPG batch 3 at HKBP Nommensen University. The results of the study are that the philosophy of education has an important role in the PPG program, providing a theoretical basis for improving teacher competence. Teachers can understand and apply ethical, moral, and scientific knowledge values ​​in teaching through the study of philosophy, including ontology, epistemology, and axiology. This research is expected to contribute significantly to the development of teacher competence.

Abstract

Penelitian ini bertujuan untuk menggambarkan tingkat kecemasan siswa dan kemampuan pemahaman matematika mereka pada materi bilangan bulat di kelas VII SMP Negeri 4 Kecamatan Pangaribuan. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif, yang berfokus pada pengumpulan dan analisis data numerik untuk menggambarkan kondisi kedua variabel tersebut tanpa menguji hubungan atau pengaruh antara keduanya. Data dikumpulkan melalui angket untuk mengukur tingkat kecemasan siswa dan tes untuk menilai kemampuan pemahaman matematika siswa. Hasil penelitian menunjukkan adanya variasi pada tingkat kecemasan siswa, yang terbagi menjadi kategori rendah, sedang, dan tinggi. Begitu juga dengan kemampuan pemahaman konsep matematika siswa mencakup beberapa indikator, seperti menyatakan ulang konsep, mengklasifikasi objek berdasarkan sifatnya, mengaplikasikan konsep, serta menyajikan konsep kedalam berbagai bentuk representasi. Penelitian ini menyajikan gambaran yang jelas mengenai distribusi kecemasan dan kemampuan pemahaman matematika tanpa menganalisis keterkaitan antara kedua variabel tersebut. Temuan ini diharapkan dapat membantu pihak pendidik untuk merancang strategi pembelajaran yang lebih efektif dan memperhatikan kondisi psikologis siswa, khususnya dalam konteks pembelajaran matematika pada materi bilangan bulat.

Abstract

The Cumulative Grade Point Average (GPA) is used in higher education to measure how well students perform in their studies. Mathematics Education students have varying GPAs each semester due to various factors. The aim of this study is to determine the type of discriminant function, or discriminant model, and identify the components that significantly influence the GPA of Mathematics Education students at HKBP Nommensen University. Another goal is to assess the accuracy of the discriminant function classification. This study involved 50 active students from the Mathematics class of 2020, 2021, and 2022. The sample was taken using a simple random sampling technique, and the research type used was quantitative, as the results are in numerical form and will be analyzed quantitatively using discriminant analysis. The research method employed is also quantitative. Based on the results, a discriminant model was obtained that describes the factors influencing the GPA of Mathematics Education students, with the equation: Y= 0.119 + 6.138X₄ + 8.120X₆ -13.910X₉. The variables that significantly affect GPA are learning motivation, mental health, and campus environment. This discriminant model can classify students with 100% accuracy, allowing it to be used to determine whether a student has a GPA below 3.75 or above/equal to 3.75.

Abstract

This study aimed to determine the effectiveness of the contextual teaching and learning model on students' problem-solving skills and mathematical reasoning abilities in linear equations with one variable. Furthermore, this study sought to investigate the level of effectiveness of the contextual teaching and learning model in enhancing students' problem-solving skills and mathematical reasoning abilities. The research employed a quasi-experimental design with the entire population of grade VIII students serving as the population. Cluster random sampling was used to select the sample. The hypothesis was tested using the F-test. The results showed that (1) the contextual teaching and learning model was effective in improving students' problem-solving skills; (2) the effectiveness of the contextual teaching and learning model in enhancing students' problem-solving skills was categorized as high; (3) the contextual teaching and learning model was effective in improving students' mathematical reasoning abilities; and (4) the effectiveness of the contextual teaching and learning model in enhancing students' mathematical reasoning abilities was categorized as moderate.

Abstract

Maths is the clearest and most unambiguous of sciences. However, for most students, mathematics is one of the most feared and difficult subjects to understand due to the lack of understanding of the concepts needed. In line with the mathematical concepts needed in learning, a teacher can relate mathematical concepts to local culture. Mathematics embedded in culture is called ethnomathematics. This research explores the concept of mathematics in Gajut Manik-manik. Gajut Manik-manik is part of the bride's outfit in Simalungun tradition which serves as a place for betel nut, areca nut, gambier, lime and tobacco. This study aims to explore the various mathematical concepts found in Gajut beads. The research method used is a qualitative method with an ethnographic approach. Data collection was done through observation, interviews, documentation, and literature study. The data collection instruments used were observation sheets, interview sheets, cameras, field notes and voice recorders. Data analysis techniques include data reduction, data presentation, and conclusion drawing. The results obtained from this study indicate that there are mathematical concepts in Gajut beads, namely the concept of tube space, circle flat and kite. Thus, it can be concluded that Gajut beads can be used as a concrete mathematics learning tool in understanding mathematical concepts.

Abstract

This study examines the influence of integrating Batak musical instruments in Student Worksheets (LKPD) on high school students' mathematical interest. The integration aims to increase students' interest in learning mathematics through a locally-based cultural approach. The research method used is quantitative with a Posttest-Only Control Group Design. The sample consists of two groups: the experimental group using Batak musical instrument-based LKPD and the control group without a similar treatment. Data were collected through a mathematical interest questionnaire and analyzed using normality tests, homogeneity tests, and t-tests. The results indicate that the data is normally distributed and there is a significant difference in mathematical interest between the two groups. Students who used the Batak musical instrument-based LKPD showed higher mathematical interest compared to the control group. In conclusion, the integration of Batak musical instruments in LKPD has a positive effect on students' mathematical interest.
