Development of instruments for measuring contextual-based video quality of fluid for physics at senior high school grade XI

Abstract

Abstract Contextual learning videos present various events related to the topic of the lesson. One of the benefits of contextual-based learning videos is to improve critical thinking, creative thinking, collaboration, and communication skills (4C). The requirement for a video to meet the standards as a learning medium is valid, practical, and effective. An instrument is needed to measure the three the quality standard of the learning media. The instrument must meet valid and reliable criteria. An instrument has been developed to measure the validity, practicality, and effectiveness of CTL-based fluid learning videos for high school physics lessons level XI. The instruments consist of (1) validity according to expert physics learning and physicists, (2) practicality according to senior teachers and high school students, and (3) effectiveness for measuring critical thinking skills, creative thinking, collaboration, oral communication, and written communication; over all 9 instrument units. Expert validation tests have been carried out and all instruments are considered valid. Experts, teachers, and students have tested the use of instruments, the test results show that all the instruments are reliable. Based on the results obtained, it can be concluded that the instrument made meets the standards as a measuring tool for the quality of contextual-based fluid learning media.
