Pengembangan Media Video Pembelajaran Fisika Berbasis Saintifik Pada Materi Pokok Gelombang Mekanik Kelas XI Semester II

Abstract

This development research aims to produce a science-based physics learning video media on the subject
matter of the second semester XI mechanical wave material that is feasible to be applied in the physics
learning process at school and determine students' responses after using the developed Media Video. The
subjects in this study were 20 Physics Education students at the 2017 Faculty of Mathematics and Natural
Sciences Unimed. This type of research is a research development or Research and Development (R&D)
using 4D Models. The instrument used in this study consisted of a media assessment questionnaire and
student analysis, a media expert team validation questionnaire, and a media trial assessment questionnaire.
The data analysis technique used in this study was descriptive. From the results of data analysis obtained by
media expert validation of 63.67% while the test area of the percentage of student responses with a sample
of 20 people amounted to 85.5% with each of these presentations included in the excellent category. So
based on the results of validation, assessment of media experts and student participant responses it can be
concluded that the physics-based physics learning video media on the subject matter of mechanical waves is
appropriate for use in the learning process
