VALIDITAS MODUL DIGITAL INTERAKTIF BERNUANSA MARITIM PADA MATERI SUBTOPIK MATERI ATURAN SINUS DAN ATURAN COSINUS

Abstract

One of the influences of the 4.0 revolution era is the development of technology that affects education. The use of current technology can be used to develop teaching materials in the form of modules. Therefore, this study aims to describe the validity of an interactive digital module with maritime nuances in the material subtopics of sine rules and cosine rules which have valid criteria. This type of research is development research. Questionnaires and documentation are data collected by researchers. The validity of the product developed was seen from the material aspects, media aspects, and language aspects so that the research instrument used was the validation sheet from each of these experts. The data analysis technique used is the descriptive method and the Method of Summated Ratings (MSR) to measure the validity of the product. The results of material validation obtained an average of 84% with the valid category. Validation by linguists obtained an average of 78% with the valid category. Meanwhile, validation by media experts obtained an average of 88% with a very valid category. Overall, the validity of the interactive digital module with maritime nuances on the material subtopic of sine rules and cosine rules obtained an average of 83% with valid criteria.
