Abstract

This study aims to determine the effect of the GASING (Easy, Fun, and Enjoyable) learning method on the mathematics learning outcomes of second-grade students at SD Negeri 125543 Lapangan Bola. This study uses a quantitative approach with a quasi-experimental method and a pretest–posttest design. The study population was all 26 second-grade students who were also used as samples. The research instrument was a learning outcome test that had been tested for validity, reliability, difficulty level, and discriminatory power. Data were analyzed using a normality test and a hypothesis test (paired sample t-test). The results showed that the average pretest score of students was 22.11 in the low category, while the average posttest score increased to 69.03 in the good category. The hypothesis test showed a significance value of 0.000 less than 0.05, which means there is a significant influence between the application of the GASING method on students' mathematics learning outcomes. Thus, the GASING method is proven to be effective in improving mathematics understanding and learning outcomes quickly, easily, and enjoyably.

Abstract

Scientific writing is one of the essential competencies that students must possess, yet it is often hindered by difficulties in managing references and proper citations. This community service aims to enhance students’ ability to write scientific papers systematically and efficiently through the utilization of Mendeley as a reference management tool. The activities were conducted in the form of workshops and hands-on practice using Mendeley, covering installation, literature management, and the creation of citations and bibliographies according to academic standards. The methods employed included a combination of demonstration, discussion, and direct practice with student participants at HKBP Nommensen University Pematangsiantar. The results of the community service indicated a significant improvement in students’ skills in managing references, facilitating citation writing, and accelerating the process of preparing scientific papers. Thus, the use of Mendeley can serve as an effective strategy to support students’ academic productivity and enhance the quality of scientific writing

Abstract

This study examines in depth the dynamics of classroom interactions in the Flipped Classroom learning model in the Elementary School Teaching and Learning Strategy course at the Elementary School Teacher Education Study Program, HKBP Nommensen University, Pematangsiantar during the even semester of the 2023/2024 academic year. With a qualitative approach and case study design, data were collected through observation, interviews, and documentation studies. The results showed that providing pre-class materials significantly improved students' readiness and understanding before class discussions. Class discussions became more in-depth and interactive thanks to this preparation, while the use of learning videos made it easier to understand complex concepts. Formative assessments provided immediate and useful feedback for students to improve their weaknesses, while focusing on metacognitive skills such as reflection and planning helped in the development of more effective learning strategies. Flipped Classroom has also been shown to improve students' time management and productivity, as well as enrich social interactions in the classroom through active involvement in both in-class and out-of-class discussions. This model is flexible in assignments, which significantly increases student motivation and engagement. In conclusion, Flipped Classroom not only improves academic understanding but also plays an important role in developing students' social and metacognitive skills, making it an effective learning model in the era of the industrial revolution 4.0.

Abstract

Membaca merupakan salah satu hal yang penting dalam segala macam proses pembelajaran. Melalui membacalah berbagai ilmu pengetahuan, yang dapat mengantarkan pada kesuksesan, bisa kita dapatkan. Kemampuan literasi membaca yang rendah di kalangan masyarakat Indonesia khususnya pada anak-anak mendorong kegiatan pengabdian ini diadakan. Hasil observasi awal menunjukkan bahwa para tenaga pengajar di rumah belajar Patmos masih pasif dalam melaksanakan gerakan literasi membaca. Para tenaga pengajar tersebut belum secara aktif memberi perhatian pada upaya peningkatan literasi membaca para anak-anak. Melalui berbagai kegiatan yang menyenangkan bagi anak-anak, tim pengabdian kepada masyarakat berusaha untuk menumbuhkan kecintaan membaca siswa melalui penerapan gerakan literasi membaca. Salah satu cara, dengan pengadaan pondok baca di rumah belajar Patmos. Kegiatan dilaksanakan 15 menit sebelum pembelajaran dimulai. Dengan upaya penerapan gerakan literasi membaca, anak-anak di rumah belajar Patmos menjadi lebih antusias dan termotivasi untuk lebih meningkatkan minat dalam membaca.

Abstract

The purpose of this study was to see the effect of the Quantum Teaching learning model used by Christian Religious Education teachers in the formation of student character. The sample in this study was 50 people. This study used descriptive methods, while the data analysis carried out in the hypothesis research was Pearson's product moment correlation with data collection tools, namely a questionnaire for Variable X (Influence of Quantum Teaching Learning Model) and Variable Y (Student Character Building) The statistical test used in this research is using the Pearson Product Moment Correlation statistical test. From the test results obtained correlation test (r) 0.96 with a determination test of 92% and to determine whether or not the correlation coefficient is significant at the real level (α) = 0.05, the "t" test is held. From the test results obtained tcount > ttable (3.19 > 1.67), then the hypothesis is accepted. Thus, it can be stated that there is an influence of the Quantum Teaching Learning model in PAK learning on the character formation of students in the era of online learning.

Abstract

This study aims to determine the effect of the Picture And Picture learning model on the learning outcomes of fourth-grade students at UPTD SD Negeri 122353 Pematangsiantar. The research sample consisted of 24 students who were given 25 test items as research instruments, which were then tested for validity, reliability, discrimination index, and difficulty level. The test results showed that 20 items were valid with a reliability of 0.913, and most items had a moderate difficulty level with good to very good discrimination power. The study involved administering a Pre-Test, teaching material using the Picture And Picture model, followed by a Post-Test. The average Pre-Test score was 49.17 and increased to 83.13 in the Post-Test. Normality testing showed a normal distribution (sig = 0.16), and the t-test confirmed a significant effect of the learning model on student learning outcomes with a significance value of 0.000 and t-count (20.305) > t-table (7.634). Thus, the Picture And Picture learning model effectively improves the science learning outcomes of fourth-grade students at UPTD SD Negeri 122353 Pematangsiantar

Abstract

Penerapan karakter pendidikan di SD Swasta YP HKBP 4 Pematangsiantar, dengan fokus pada faktor hambatan dan strategi penanggulangannya. Hambatan utama meliputi faktor lingkungan yang kurang mendukung, sikap cuek dari orang tua dan siswa, serta keterbatasan waktu guru. Upaya mengatasi hambatan tersebut dilakukan melalui pemberian masukan, pertemuan orang tua, teguran tegas, dan koordinasi yang efektif. Penerapan nilai-nilai karakter seperti religius, peduli lingkungan, tanggung jawab, jujur, dan disiplin dilakukan melalui kegiatan rutin dan teladan dari guru. Konsep utama dalam pembentukan karakter adalah pembiasaan dan pemberian contoh yang baik, yang didukung oleh motivasi strategi, teguran, dan kerjasama dengan orang tua. Hasil penelitian menunjukkan bahwa penerapan karakter pendidikan yang konsisten dapat membangun budaya karakter positif dan bertanggung jawab pada kalangan siswa, sehingga mendukung terciptanya lingkungan sekolah yang kondusif dan berkarakter.
