Abstract: videos make science concepts more concrete so that the students understand the material more easily. This study aimed to explain the differences in students’ cognitive learning outcomes through the application of learning videos on Global Warming material. This research was a quantitative research with a quasi-experimental method. The research design was a posttest only control design. The samples of this research were students of class VII-B SMP A. Wahid Hasyim Jombang as the control class and class VII-C as the experimental class. The research instrument was a test for cognitive learning outcomes. The data were analyzed by prerequisite test, then, followed by hypothesis testing using Independent Samples Test. The analysis results showed that the score of sig. (2-tailed) 0.000, so that there was a significant difference between the cognitive learning outcomes of the experimental class and the control class. It was concluded that there were differences between students’ cognitive learning outcomes taught using videos and Power Point media. Keywords: learning media of video, global warming, cognitive learning outcomes Abstrak: video membuat konsep IPA menjadi lebih konkrit sehingga memudahkan siswa memahami materi. Penelitian ini bertujuan untuk menjelaskan perbedaan hasil belajar kognitif siswa melalui penerapan video pembelajaran pada materi Pemanasan Global. Penelitian ini merupakan penelitian kuantitatif dengan metode quasi experiment. Desain penelitian berupa posttest only control design. Sampel penelitian meliputi siswa kelas VII-B SMP A. Wahid Hasyim Jombang sebagai kelas kontrol dan kelas VII-C sebagai kelas eksperimen. Instrumen penelitian ini berupa lembar tes hasil belajar kognitif. Data dianalisis dengan uji prasyarat kemudian dilanjutkan uji hipotesis menggunakan Independent Samples Test. Hasil analisis menunjukkan bahwa nilai sig. (2-tailed) 0,000, artinya ada perbedaan siginifikan antara hasil belajar kognitif kelas eksperimen dengan kelas kontrol, sehingga disimpulkan bahwa terdapat perbedaan hasil belajar kognitif siswa yang dibelajarkan menggunakan media video dengan yang belajarkan menggunakan media Power Point.Kata kunci: video pembelajaran, pemanasan global, hasil belajar kognitif.DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp222-233
