Penerapan Model Pembelajaran Contextual Teaching and Learning melalui Video pada Materi Energi dalam Sistem Kehidupan

The Application of Contextual Teaching and Learning Model with Video on Energy Materials in Living Systems

Penelitian ini bertujuan untuk mengetahui hasil belajar siswa setelah diterapkan model pembelajaran Contextual Teaching and Learning (CTL) dengan pendekatan SETS melalui video pada materi Energi dalam Sistem Kehidupan. Desain penelitian menggunakan Pre-Experiment Design dengan One-Group Pretest-Posttest Design. Metode pengambilan sampel yaitu purpose sampling dengan subjek penelitian siswa kelas VII-H di SMPN 26 Surabaya sejumlah 22 orang. Pengumpulan data dilakukan melalui lembar pengamatan (aktivitas siswa dan keterlaksanaan pembelajaran), tes hasil belajar, dan angket respon. Lembar pengamatan dianalisis menggunakan skala likert (rentang skor 1-4), tes hasil belajar meliputi pretest dan posttest (masing-masing berjumlah 15 soal) yang dianalisis dengan uji N-Gain, dan angket respon menggunakan skala Gutmann (Ya dan Tidak). Hasil aktivitas siswa dan keterlaksanaan pembelajaran pada dua pertemuan dikategorikan dengan sangat baik. Hasil belajar sejumlah 15 siswa mencapai persentase sebesar 68% (kriteria: tinggi) dan 7 siswa mencapai persentase 32% (kriteria: sedang). Peningkatan skor N-Gain diperoleh sebesar 0,76 yang dikategorikan tinggi dan sejumlah 22 siswa tuntas sehingga ketuntasan klasikal belajar mencapai 100%. Respon siswa yang tertarik dengan adanya penerapan model CTL melalui video didapatkan rata-rata persentase sebesar 91,6%. Berdasarkan hasil penelitian disimpulkan bahwa penerapan model pembelajaran CTL dengan pendekatan SETS melalui video pada materi Energi dalam Sistem Kehidupan dinyatakan tepat dan berhasil meningkatkan hasil belajar siswa.

This study aims to determine student learning outcomes after applying the Contextual Teaching and Learning (CTL) learning model with the SETS approach through videos on Energy in Living Systems. The research design used Pre-Experiment Design with One-Group Pretest-Posttest Design. The sampling method is purpose sampling with the research subjects of class VII-H students at SMPN 26 Surabaya as many as 22 people. Data was collected through observation sheets (student activities and learning implementation), learning outcomes tests, and response questionnaires. Observation sheets were analyzed using a Likert scale (score range 1-4), learning outcomes tests included pretest and posttest (15 questions each) which were analyzed using the N-Gain test, and the response questionnaire using the Gutmann scale (Yes and No). The results of student activities and the implementation of learning in two meetings were categorized very well. The learning outcomes of 15 students reached a percentage of 68% (criteria: high) and 7 students reached a percentage of 32% (criteria: moderate). The increase in the N-Gain score was obtained by 0.76 which was categorized as high and a total of 22 students completed so that the classical mastery of learning reached 100%. The responses of students who are interested in the application of the CTL model through video obtained an average percentage of 91.6%. Based on the results of the study, it was concluded that the application of the CTL learning model with the SETS approach through video on Energy in Living Systems was stated to be appropriate and succeeded in improving student learning outcomes.
