Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan berpikir kritis peserta didik sebelum dan sesudah diterapkan model pembelajaran inkuiri terbimbing. Penelitian ini dilaksanakan di SMP Negeri 2 Afulu. Jenis penelitian ini adalah kuasi eksperimen dengan desain non equivalent control group design. Pengumpulan data dilakukan dengan menggunakan tes dan lembar observasi. Hasil penelitian ini menunjukkan bahwa terdapat perbedaan kemampuan berpikir kritis peserta didik sebelum dan sesudah diterapkan model pembelajaran inkuiri terbimbing. Sebelum mendapatkan perlakuan pada kedua kelas, diperoleh rata-rata skor kemampuan awal (pretest) berpikir kritis kelas eksperimen 43,52 dengan standar deviasi 9,33 dan skor kemampuan awal (pretest) berpikir kritis kelas kontrol 43,76 dengan standar deviasi 9,11. Setelah dilakukan pembelajaran yang berbeda diperoleh hasil rata-rata posttest berpikir kritis peserta didik kelas eksperimen 83,36 dengan standar deviasi 6,84 dan hasil rata-rata posttest berpikir kritis peserta didik kelas kontrol 72,72 dan standar deviasi 8,24.
This service activity aims to provide students with an understanding of learning on physics material through the experimental method using teaching aids. The place where this activity was carried out was SMP N 1 Tapian Nauli. This activity is divided into several stages, the first is the introduction of students by the student-teacher, the second stage is the delivery of learning materials, and the third stage is conducting experiments through teaching aids that have been provided by the teacher. The last stage is conveying the conclusions from the experiments carried out. This activity provides benefits in increasing student understanding of physics learning through the experimental method. With the experimental method used, students become more active and can see directly the physical phenomena that occur through observation. The application of this tutoring through teaching aids is expected to increase students understanding of learning not only with theories and formulas.
This study aims to determine the effect of discovery learning models on student learning outcomes in class VII heat material at SMP Negeri 2 Manduamas with quasi-experimental research methods and the population in the study, namely class VII SMP students with a total sample of 82 students. The sampling technique is Cluster Sampling. The instrument used was the test of learning outcomes in the form of multiple choice as many as 20. Before being given treatment to the two classes, the results obtained - the average pretest score for the experimental class was 49.63 and the average score for the control class was 49.44. After being given different treatments, the average posttest score for the experimental class was 74.26 and the average posttest score for the control class was 64.26. The results of the posttest data prerequisite test stated that the sample was normally distributed and homogeneous. Then, a one-sided t-test (a = 0.05) was performed with the condition that t count > t table or 4.13 > 1.67. So it can be said that there is a significant effect of discovery learning model on student learning outcomes in heat material for class VII SMP.
This activity is to improve the academic climate that is creative, innovative, visionary, solutive and independent and to improve the quality of students in higher education so that later they can become members of the community who have academic and professional abilities who can apply, develop and disseminate science, technology and art as well as enrich the national culture. This Community Service (PkM) activity was carried out at SMP Negeri 1 Tapian Nauli, Jalan Sibolga-Barus KM 0.8 Tapian Nauli, Central Tapanuli Regency. Community service activities are carried out from 02 to 26 February 2022. Not all learning that takes place in schools can be accepted and understood by students. Every activity carried out is expected to provide benefits, as well as community service activities organized by the HKBP Nommensen Medan FKIP Student Team. This community service activity is expected to increase the enthusiasm for learning for students at SMP Negeri 1 Tapian Nauli.
Mengingat meluasnya virus covid-19 di Penjuru dunia telah memusnahkan banyak manusia. Segala usaha sudah dilaksanakan oleh semua negara termasuk negara Indonesia. Pemerintah Indonesia telah berusaha keras menangani pandemic covid-19 Hingga saat ini semua sektor termasuk pendidikan harus menaatinya. Berbagai macam cara dilakukan untuk mengatasi permasalahan di bidang pendidikan, salah satunya adalah pengabdian kepada masyarakat yang dilakukan oleh mahasiswa Universitas HKBP Nommensen Medan. Dengan adanya program yang dilaksanakan oleh pihak kampus mahasiswa dapat mendistribusikan ilmu ataupun membantu siswa/siswi mengenai pembelajaran terlebih di masa pembelajaran tatap muka terbatas. Adapun metode yang digunakan penulis adalah metode kualitatif yang dimana data diperoleh dari hasil observasi serta wawancara guru serta test kepada siswa kelas IX di SMPN 1 Tapian Nauli. Berdasarkan pengamatan dari observasi, wawancara dan tes penerapan PTM di SMPN 1 Tapian Nauli sesuai dengan panduan pelaksanaan PTM dan tetap menerapkan protokol kesehatan di sekolah.
