The Effectiveness of the Use of Video Media on Learning on the Competence of Scalp and Hair Care of Vocational High School Students of Beauty Department

Abstract

The objective of this study is to determine the effectiveness of the use of video media in improving student learning outcomes in the competence of caring for the scalp and hair. The research method used was an experimental method with pretest and posttest control group design. This study used test as a research data collection instrument. The validity test of the test questions was analyzed by using product moment correlation and the reliability testi was analyzed by using the Kuder-Richardson-20 formula (KR-20). The contents validity of video instrument and the performance of students were analyzed by using the Contents Validity Ratio (CVR) formula, meanwhile, the reliability test was analyzed by using Cohens Kappa. The study population was a class of X beauty students at State Vocational High School 3 Pati. The placement of the students into the experiment group and the control group used a random assigment technique by drawing. Based on the results of the t-test, the initial average of learning outcomes in the competency of caring the scalp and hair of the control group is 54.5704, it improves into 75.0593 with the improves of 37.54%, including in the “low” category. Whereas, in the experiment group, the initial average learning outcomes in the competency of caring for the scalp and hair is 55.9438, it increases to 83.3281, with the improves of 48.95%, including in the “medium” category. The difference in the improvement in learning outcomes in the experiment group is higher than the difference in the improvement in learning outcomes of the control group (48.95% > 37.54%) so that it can be synthesized that the use of video media is effective in learning competency in caring for the scalp and hair in class of X beauty students of State Vocational High School 3 Pati.

3D Molecular Interactive Multimedia for Building Chemistry Students' Spatial Ability

“…The rotation and relation types fall in the large and strong categories, respectively. The magnitude of the effect size on the three types of spatial ability (spatial relationships, spatial orientation, and spatial visualization), according to Cohen [21], is classified as large. Again, the values indicate that the teaching of molecular geometry assisted 3D-MIM effectively increases the three dimensions of spatial ability.…”

Video Animasi yang Dapat Meningkatkan Perilaku Hidup Bersih dan Sehat (PHBS) pada Masa Pandemi Covid 19 untuk Anak Usia Dini

“…Temuan penelitian ini diperkuat dengan penelitian sebelumnya menyatakan media video pembelajaran sangat efektif digunakan pada proses pembelajaran (Pamungkas et al, 2018;Suryana & Hijriani, 2021). Penggunaan video pembelajaran animasi edukatif sangat efektif sebagai media untuk mengembangkan semangat dan motivasi siswa (Miranda, 2019;Nurhayati et al, 2018). Video animasi tentang PHBS anak dapat meningkatkan kemampuannya dalam menjaga kebersihan serta kesehatan diri, karena ada motivasi yang tumbuh setelah menyimak dan melihat cerita video animasi tentang bagaimana kita menjaga kebersihan dan kesehatan di masa pandemi Covid 19.…”

Video Pembelajaran Animasi Berbasis Role Playing Tema Profesi pada Anak Usia Dini

“…Temuan penelitian ini diperkuat dengan penelitian sebelumnya menyatakan media video pembelajaran sangat efektif digunakan pada proses pembelajaran (Pamungkas et al, 2018;Suryana & Hijriani, 2021). Penggunaan video pembelajaran animasi edukatif sangat efektif sebagai media untuk mengembangkan semangat dan motivasi siswa, hal ini ditinjau melalui kriteria pembelajaran video untuk anak, yaitu syarat ideal media pembelajaran video harus memenuhi beberapa kriteria antara lain kejelasan pesan, berdiri sendiri, akrab dengan anak, representasi isi, visualisasi atau kualitas gambar baik dapat digunakan klaisikal maupun individual (Miranda, 2019;Nurhayati et al, 2018). Kejelasan dan keterkaitan antara media pembelajaran dengan indikator, tujuan, dan materi, harus menjadi perhatian dan pertimbangan pengajar untuk memilih dan menggunakan media dalam proses pembelajaran di kelas sehingga media yang digunakan lebih efektif dan efisien untuk mencapai tujuan pembelajaran (Krissandi & Rusmawan, 2015).Pengembangan video pebelajaran berbasis Role Playing ini sangat tepat dilakukan karena mampu meningkatkan potensi siswa dalam belajar menjadi lebih efektif.…”
