Abstract

This study aims to produce a valid contextual based learning video of wave material. This research uses the ADDIE development model which consists of five stages, namely analyze, design, development, implementation, and evaluation. The instruments used to test the validity of contextual-based learning videos were expert learning validation instrument, physicist validation instrument, and linguist validation instrument. The learning expert validation instrument was assessed by a learning expert, the physicist's validation instrument was assessed by a physicist, and the linguist's validation instrument was assessed by a linguist. The validity data analysis refers to the Aiken's V coefficient. The learning video is declared valid if it is in the valid category, namely ≥ 0.6. Based on the results of the validation, it was found that the average value of the validation of learning experts was 0,75, the average value of validation of physicists was 0,74, and the average value of linguist validation was 0,87. So the contextual-based learning video of the wave material developed is valid both in terms of construct, content, and language feasibility. This means that the contextual-based learning video of wave material is suitable for use in the learning process so that it can improve student’s critical thinking, creative, collaboration, and communication skill.
