Validity of Interactive Multimedia on Metal Coating Learning Developed Using the ADDIE Model

The Metal Coating course in Unimed's Mechanical Engineering Education Department only uses learning media the form of printed textbooks and there is no interactive that can improve student competence affective psychomotor domains. To increase competency metal plating courses, multimedia has been validated for its quality needed. This study aims to validate using ADDIE development model. As three acquisitions validity, namely analysis requirements, determining objectives designing multimedia, as well developing involving several material experts, design activity validators. Data collection techniques validation are carried out by distributing questionnaires. assessment criteria used a Likert scale which was analyzed descriptively. results showed validity expert 89.7% very good category, 91.58% category 88.3% category. from these data it be concluded use teaching process developed valid implemented
