Abstract

This community service was conducted in Penampen Village, Karo Regency, as part of the implementation of the Community Service Program (KKN) for the KKN course, accompanied by field supervising lecturers. This article aims to explore sustainable village development strategies to achieve Indonesia's advancement. By involving the community in the development process, it can become a driving force for national economic growth. The activities focus on enhancing local residents' skills and education. By involving the community in training and educational programs, it helps them acquire new knowledge that can improve their living standards. Teaching basic technology skills opens up new job opportunities or increases efficiency in daily work. Introducing technology to children at the elementary, middle, and high school levels is an important step in preparing students to face future challenges. The community's enthusiasm is evident from their active participation, both in material and non-material support. This shows that the programs implemented are relevant to their needs and can foster a sense of ownership towards the program. Good cooperation between KKN members and the village community is key to the success of this program. This synergy creates a conducive environment for learning and growing together. With all these activities, it is clear that the KKN program not only provides short-term benefits but also has the potential to bring long-term positive changes to the village.

Abstract

Penelitian ini bertujuan untuk meningkatkan keterampilan berpikir kritis siswa kelas X di SMA Negeri 12 Medan pada tahun ajaran 2024/2025. Upaya ini dilakukan dengan menerapkan model pembelajaran kooperatif tipe Think Pair Share (TPS) yang didukung oleh LKPD elektronik selama proses pembelajaran berlangsung. Penelitian ini melibatkan 30 siswa kelas X sebagai subjek. Metode yang digunakan adalah penelitian tindakan kelas (PTK) yang terdiri dari dua siklus, di mana setiap siklus mencakup dua kali pertemuan untuk pembelajaran dan satu kali pertemuan untuk evaluasi kemampuan berpikir kritis serta tanggapan siswa terhadap pembelajaran yang diterapkan. Hasil penelitian menunjukkan bahwa penerapan model cooperative learning tipe TPS dengan bantuan LKPD elektronik memberikan dampak positif terhadap peningkatan kemampuan berpikir kritis siswa. Hal ini terlihat dari peningkatan skor rata-rata kemampuan berpikir kritis yang awalnya hanya 42,39 dengan ketuntasan klasikal 0%, meningkat menjadi 66,25 dengan ketuntasan 40% setelah siklus pertama, dan mencapai rata-rata 85 dengan ketuntasan klasikal 86,67% setelah siklus kedua. Berdasarkan temuan tersebut, dapat disimpulkan bahwa penerapan model pembelajaran kooperatif tipe TPS yang didukung LKPD elektronik efektif dalam meningkatkan kemampuan berpikir kritis siswa kelas X di SMA Negeri 12 Medan.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah ada pengaruh faktor grit terhadap prestasi akademik pada mata pelajaran matematika dengan mempertimbangkan faktor internal dan eksternal yang mempengaruhinya. Grit diukur melalui skala yang mengukur ketekunan dan keberanian dalam menghadapi tantangan. Penelitian ini juga mempertimbangkan faktor-faktor internal seperti motivasi intrinsik dan self-efficacy, serta faktor eksternal seperti dukungan sosial dan lingkungan belajar. Metode Penelitian yang digunakan adalah penelitian kuantitatif dengan teknik pengumpulan data berupa kuesioner dan tes yang diberikan diakhir semester yang disebarkan kepada sampel siswa kelas 7, 8 dan kelas 9. Analisis data dilakukan menggunakan teknik regresi untuk mengetahui hubungan antara grit dan prestasi akademik, serta untuk melihat seberapa besar pengaruh faktor internal dan ekstenal dalam memediasi hubungan tersebut. Hasil penelitian menunjukkan adanya hubungan positif antara grit dan prestasi akademik pada mata pelajaran matematika siswa sebesar 77,14. Selain itu faktor internal seperti motivasi intrinsik dan self-efficacy terbukti memediasi  hubungan antara grit dan prestasi akademik siswa, sedangkan faktor eksternal seperti dukungan sosial dan lingkungan belajar juga memiliki pengaruh yang signifikan. Temuan ini mengindikasikan pentingnya pengembangan grit pada siswa SMP sebagai upaya untuk meningkatkan prestasi akademik mereka, dengan memperhatikan peran faktor internal dan eksternal yang turut mempengaruhi. Implikasi praktis dari penelitian ini adalah perlunya perhatian lebih terhadap pembinaan grit pada tingkat pendidikan, serta pentingnya dukungan sosial dan lingkungan belajar yang kondusif dalam meningkatkan prestasi akademik pada matapelajaran matematika.

Abstract

This research aims to determine the effect of the Jigsaw Type Cooperative learning model on the learning outcomes of class III students. This research method is descriptive quantitative. The research population was class III students at State Elementary Schools in Hamparan Perak, totaling 86 students. Sampling was taken using random sampling and 30 students were used in class III at SD Negeri 101743. The results of this research show that student learning outcomes are in the very good category with 78.2. By testing the correlation, it can be seen that the correlation coefficient is rcount (0.845) ≥ rtable (0.361), so ha is accepted. There is an influence of the Jigsaw Type Cooperative model on the learning outcomes of class III students at SD Negeri 101743 Hamparan Perak. It can also be seen from the t-test where tcount ≥ ttable, namely 8.458 ≥ 2.042, thus stating that ha is accepted. This shows that there is a significant positive influence from the use of the Jigsaw Type Cooperative model on the learning outcomes of class III students at SD Negeri 101743 Hamparan Perak for the 2023/2024 Academic Year.

Abstract

This research aims to determine the effect of the Reward-based Problem Based Learning learning model on the mathematical learning outcomes of class IV at SD Negeri 060919 Medan Sunggal for the 2024/2025 academic year. The procedures and techniques used in research are called research methodology. The aim of this quantitative research strategy is to identify factors that contribute to the success or failure of various learning approaches in improving academic achievement in mathematics classes with fractions as the main material in class IV. This can be seen from the average student pretest score of 43.33 and the average score of -student posttest average 74.33. Based on the results of the hypothesis test (t-test) with a value of ≥, namely 5,806 2.048 at a significance level of 0.000 0.05. These data can show that Ha is accepted, namely that there is an influence between the Problem Based Learning learning model based on giving rewards (X) on student learning outcomes (Y). At the end of the lesson, the researcher provided treatment using a Problem Based Learning learning model based on giving rewards when teaching, then the researcher tested the students again by giving a posttest of 10 questions to see the value of the treatment given. By using the Problem Based Learning learning model based on giving rewards, students' posttest learning outcomes increased with an average score of 74.33 and there were 29 students who completed and 1 student who did not complete. So the final step that the researcher took was to give a 25-item Problem Based Learning model questionnaire to students.

Abstract

The aim of this study is to determine the effect of using the STEM-PJBL learning model on students’ creative thinking skills. This study is a quantitative quasi-experimental study. The population used in this study consists of all junior high school students at an A-accredited school in the Binjai Timur sub-district. The sample comprises two classes: Class VII A, which serves as the experimental class implementing STEM-based PJBL, and Class VII B, which serves as the control class receiving conventional instruction. The instruments used in this study are pre-test and post-test questions. The data analysis techniques in this study involved prerequisite tests (normality and homogeneity tests) and hypothesis testing using the t-test. The results of the independent samples t-test showed that the calculated t-value was greater than the critical t-value (2.390 > 1.675) and the significance level was 0.002, which is less than 0.05. Therefore, H₀ is rejected and H₁ is accepted. Consequently, it can be concluded that learning using the STEM-based PBL model has an effect on students’ creative thinking skills.
