Learning that occurs in schools certainly has many obstacles and difficulties for students. As a result of online learning that was previously done, many students did not understand the learning material. Learning that occurs and takes place for students in science lessons, especially physics, has been a difficult lesson because of the many formulas and theories that tend to be memorized so that students feel less interested. In physics lessons, experiments are needed to improve students' understanding, so tutoring is carried out after school to overcome students' difficulties using teaching aids with the experimental method. Community service activities with tutoring are carried out at SMP Negeri 1 Tapian Nauli. Props used in electrical circuit material. With props that have been made can help students gain understanding and maximum learning outcomes in the tutoring carried out. The development of this electric circuit aid helps students to practice skills and understanding on series circuits and parallel circuits. The results of this tutoring activity increased student interest and learning outcomes, seen the average value of students before using the electric circuit teaching aid was 34.69 and after using the electric circuit teaching aid 86.57. Based on the N-Gain analysis, it is known that student learning outcomes are categorized as high and the results of the T test (Paired Sample Test) show a significant difference. The electric circuit teaching aids developed are very feasible, practical and effective to use in learning for students.
The low learning absorption of students reflects the gap between the demands of the curriculum and the level of students' thinking abilities. The inability of students to do a task is not only because they do not have the necessary prerequisite knowledge, but also their limited ability to process the amount of information received. This study aims to analyze the relationship between mastery of science concepts, especially physics, on students' ability to solve physics problems. This research is an experimental research with a pre-experimental type and a one-shot case study design. The population in this study were 9th grade junior high school students. Determination of the sample was carried out by purposive sampling method, in order to obtain a sample of 48 students. Data collection was carried out using an instrument in the form of an achievement test for mastery of the concept of science (physics). Data analysis was carried out descriptively and inferentially. The results showed that the mean (average) was 77.40 and the standard deviation (sd) was 6.58, which was included in the good category, while for the physics problem solving ability test the mean (average) was 80.16, and the standard deviation (sd) was 6.28 which was also categorized as good. which can exceed the minimum completeness criterion (KKM) score above 70. The magnitude of the correlation coefficient index (r) is 0.815 (high), with a coefficient of determination (r2) of 0.6642, which indicates that at least 66.42% mastery of the concept of science (Physics) ) can contribute to students' ability to solve physics problems.
Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe numbered heads together terhadap hasil belajar peserta didik . Jenis penelitian ini adalah quasi eksperimental dengan populasi seluruh peserta didik kelas VIII SMP Negeri 1 Bilah Hulu. Penarikan sampel penelitian dilakukan secara non random dengan teknik purposive sampling yaitu kelas VIII-1 sebagai kelas eksperimen dan VIII-2 sebagai kelas kontrol yang masing-masing terdiri dari 30 orang. Instrumen penelitian yang digunakan adalah terdiri dari lembar observasi aktivitas belajar peserta didik dan tes objektif dalam bentuk pilihan berganda. Berdasarkan hasil analisis data setelah diberikan perlakuan yang berbeda, diperoleh nilai rata-rata posttest kelas eksperimen 86,50 dengan standar deviasi 6,58 dan nilai rata-rata posttest kelas kontrol 74,83 dengan standar deviasi 8,46. Sebelum diuji dengan uji-t, dilakukan uji prasyarat yang masing-masing sampel memiliki data yang normal dan homogen. Hasil perhitungan uji-t satu pihak data posttest untuk ?=0,05 diperoleh thitung = 3,49 dan ttabel = 1,67 yang mengindikasikan bahwa thitung > ttabel, sehingga H0 ditolak dan Ha diterima. Disimpulkan bahwa terdapat pengaruh signifikan model pembelajaran kooperatif tipe Numbered Heads Together (NHT) terhadap hasil belajar peserta didik
Merdeka Belajar Kampus Merdeka (MBKM) adalah salah satu upaya pemerintah untuk mencerdaskan peserta didik di masa pandemic covid-19 terutama mereka yang tinggal di daerah 3T. Salah satu program MBKM yaitu kegiatan kampus mengajar yang telah diperkenalkan dan dilaksanakan semenjak 12 oktober hingga 18 Desember 2020. Selanjutnya pada awal januari 2021 penyelenggara MBKM menetapkan pelaksanaan kampus mengajar angkatan ke-1. Sekolah Dasar Negeri SD Negeri 094164 Partimbalan salah satu sekolah sasaran kampus mengajar angkatan ke-2 yang pelaksanaannya dimulai tanggal 2 Agustus hingga 18 Desember 202 yang menerjunkan tiga orang mahasiswa dari 3 perguruan tinggi dan bidang ilmu yang berbeda dan dibimbing oleh satu orang dosen pembimbing (DPL). Sebelum mahasiswa melaksanakan kegiatan, pihak Kemendikbudristekdikti membekali mereka mulai tanggal 22 sampai 30 juli 2021 secara online. Hasil yang diperoleh selama melaksanakan program kegiatan kampus mengajar angkatan ke-2 berdampak positif terhadap kemampuan literasi dan numerasi peserta didik. Selain itu guru dan pihak sekolah terbantu dengan adanya adaptasi teknologi dalam pelaksanaan asesmen kompetensi minimum (AKM).
