Abstract

The aim of this research was to determine: 1) Implementation of role playing in class V of SD Al-Ittihadiyah, 2) speaking skills of class V students of SD Al-Ittihadiya, 3) the influence of role playing on the speaking skills of class V students of SD Al-Ittihadiyah. The method in this research uses quantitative research, the type of research used is quasi-experimental. The population at this time is 38 people, all of them are class V students at Al-Ittihadiyah Elementary School for the 2023/2024 academic year. The sampling technique used in this research is total sampling. The research instruments and tools used to collect data in this research are observation. The data analysis techniques used are Descriptive Statistical Data Analysis and Inferential Statistical Data Analysis. Based on the results of data analysis, it was found that 1) The speaking skills of fifth grade students at Al-Ittihadiyah Elementary School showed that the average speaking skills of students in the control class who did not receive treatment received a score of 65.26, while those who received treatment using Role Playing in the experimental class received a score of 76. .58, 2) The application of role playing in Class V of Al-Ittihadiyah Elementary School shows an increase according to the results of data analysis in the average level of students' speaking skills after implementing Role 76.58. This average value shows that the students' speaking ability after implementing role playing is higher than the average value of students' speaking ability before being given treatment. 3) The effect of role playing on the speaking skills of fifth grade students at SD Al-Ittihadiyah is 65.26 with a standard deviation of 10.603. This means that there is an increase in the average student's speaking ability. The average value before being given treatment was 56.84, with a standard deviation of 13.664, and the value after being given treatment was 76.58 and a standard deviation of 6.882. Finally, based on the results of the independent t test, the Sig (2 tail) value was 0.000 < 0.005. Accepted, this means that there is an influence between the role playing learning model and students' speaking skills in Indonesian language learning at SD Al-Itiihadiyah T.A 2023/2024.

Abstract

Education and culture are habits that are interconnected with human life. In education, culture can be used as a medium of learning both in schools and in culture itself. North Sumatra has various unique ethnicities, one of which is the Toba Batak which must be preserved and passed down from generation to generation. One of the Toba Batak cultures is the Taganing , a traditional musical instrument consisting of five drums with different heights and diameters that produce different tones and are played by two players. The purpose of this study is to explore what mathematical concepts exist in the Taganing  musical instrument so that it can be implemented in learning mathematics.This research uses qualitative with ethnography methods with research instruments in the from of observation and documentation. The results of this study indicate that the Taganing  musical instrument contains the concept of geometry and integral calculus.

Abstract

Biology teachers have not made regional potential a source of learning. The natural environment around the school is used to support teacher explanations that do not create exploratory. This study aims to determine the validity, practicality, and effectiveness of the integrated module of the local potential of South Tapanuli for the biodiversity of the Andaliman (Zanthoxylum acanthopodium DC) plant. The research uses the Research and Development (R&D) method referring to the 4-D development model developed by Thiagarajan. The small group trial subjects consisted of 14 students of class X MIA-1. The results of the development module research show validity values of 87% and 95% by teaching module and material experts, 87% and 83% practicality values by biology teachers and students, while effectiveness based on individual mastery of student learning outcomes achieves classical mastery of  85% . The overall results meet the valid, practical and effective categories, so that the development module deserves to be a teaching material in learning activities about andaliman plants.ABSTRAK: Guru biologi belum menjadikan potensi daerah sebagai sumber belajar.

Abstract

Penelitian ini bertujuan meningkatkan literasi matematika siswa kelas X SMKN 1 Aek Nabara Barumun melalui model Project-Based Learning (PjBL). Menggunakan desain one group pretest-posttest, intervensi dilakukan selama empat pertemuan pada semester genap 2024/2025 dengan 16 siswa. Hasil analisis menunjukkan peningkatan signifikan skor pretest ke posttest, dengan rata-rata N-Gain sebesar 0,57 (kategori sedang). Temuan ini menunjukkan efektivitas PjBL dalam mendorong pembelajaran aktif dan pemecahan masalah, serta layak dipertimbangkan sebagai alternatif pendekatan oleh guru matematika di SMK. This study aims to improve the mathematical literacy of tenth-grade students at SMKN 1 Aek Nabara Barumun through the Project-Based Learning (PjBL) model. Using a one-group pretest-posttest design, the intervention was conducted over four meetings in the even semester of 2024/2025 with 16 students. The analysis showed a significant increase in pretest-posttest scores, with an average N-Gain of 0.57 (moderate category). These findings demonstrate the effectiveness of PjBL in encouraging active learning and problem-solving, and are worthy of consideration as an alternative approach for mathematics teachers in vocational high schools.

Abstract

Spatial visualization ability is very important in learning geometry of solid shapes because it allows students to imagine, manipulate, and represent three-dimensional objects, but many students still have difficulty in imagining the shape of solid shapes in mathematics learning due to the lack of learning media based on mathematical spatial visualization. This research aims To examine the impact of Augmented Reality (AR) media on spatial visualization of students' mathematical spatial visualization abilities. The study was conducted at Mts Darul Ulum Budi Agung Medan with a quantitative approach and one group pretest - posttest design. Class samples were randomly selected, namely class VIII-2, totaling 32 learners. The instruments used were test and student questionnaires response questionnaires. Data were analyzed through normality tests, homogeneity, N - Gain, and paired sample t - test. The results of the study showed that the average student score increased from 42.91 to 75.19. The t test showed a significance value of 0.000 <0.05, which means that the use of AR has a significant effect on students' spatial visualization b most students experienced an increase in the moderate category. A total of 91% of students also responded positively to AR-based learning. Thus, AR media has proven to be an effective learning alternative for improving mathematical spatial visualization skills in geometric geometry.

Abstract

Proses pembelajaran pada beberapa sekolah belum dilaksanakan secara optimal. Saat melakukan observasi lapangan, sesuai kenyataan yang terjadi di temukan beberapa hal seperti, 1) guru belum memusatkan pembelajaran, 2) kurangnya peran siswa dalam proses pembelajaran, 3) suasana yang kurang kondusif. Dalam hal ini pendekatan pembelajaran yang cocok untuk digunakan yaitu kombinasi pendekatan Joyful Learning berbantukan metode Mind Maps dalam kombinasi pendekatan dan metode ini maka akan terlihat bagaimana siswa dapat berperan aktif dalam proses pembelajaran. Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan Joyful Learning terhadap hasil belajar pada materi sistem koordinasi kelas XI MIA SMA NEGERI 1 PANCURBATU. Jenis penelitian ini adalah penelitian Quasi Eksperiment dengan menggunakan desain pretest posttes control group design dengan dua kelas yaitu eksperimen dan kontrol. Teknik pengumpulan data menggunakan instrumen tes yang berupa piliha berganda. Teknik analisis data menggunakan program SPSS versi 22. Berdasarkan uji hipotesis menggunakan “Independent sample t test” dan uji regresi linier sederhana menunjukkan nilai Sig. (2-tailed) sebesar 0,005 < 0,05, dan nilai R² 0,976, maka dapat disimpulkan bahwa H₀ ditolak dan Hₐ diterima. Hasil penelitian ini diharapkan dapat memberikan informasi sebagai dasar pertimbangan, pendukung dan sumbangan pemikiran untuk penelitian berikutnya.
