The Validity of Contextual-Based Learning Video on the Physics Fluid Material For Senior High School

Entering the 21st century, human needs are increasing along with the development of technology. Various demands occur that require humans to improve their quality. Teachers as educational subjects play an important role in providing provisions for students to develop and improve their quality through the use of instructional videos. Based on the problems encountered, it turns out that videos used by teachers in learning have not met the needs of the 21st century. To meet the needs of the 21st century, A contextual-based learning video was developed. In order for the video to suit the needs, the video quality was tested through the validity test. This type of research used a Research and Development referring to Addie's Development Model. The instrument used was a questionnaire instrument which had five Likert scales. Then, the data were analyzed by using Aikens'V formula. Based on the results and the discussion that has been done, it illustrated that the contextual-based learning video on the physics fluid material for SMA is in the valid category and can be used as a physics learning medium in schools.
