Validity and Reliability of Instruments in Physical Education Learning Multimedia

Abstract

Some current studies need to conduct validity and reliability on these instruments. This study aims to measure the validity and reliability of learning multimedia tools. Instrument validation and reliability are determined using three quantitative methods with three main stages or steps, namely expert assessment (content validation), theory test (logical validation), and data test (construct validation). The research distributed questionnaires through Google Forms. Instrument validity data is based on the average score of the research subject's assessment. Media experts scored 92.68%, 90.5%, and 94.7% on three aspects. In contrast, material experts scored 89.50%, 88%, and 96% on three elements. KMO and MSA factor analysis tests covering three aspects produced values: The content aspect is 0.976, the learning/programming aspect is 0.962, and the display aspect is 0.978. The instrument's reliability, divided into three elements, is reliable because the Cronbach alpha value is higher than 0.7. The findings of this study provide new insights that multimedia development needs to be measured using the right instrument, the right instrument, valid and reliable. This research results in a multimedia evaluation instrument comprising content, appearance, learning, and programming. This research will undoubtedly provide positive things to evaluate multimedia in physical education.
