Abstract
Interactive multimedia for learning chemistry has been developed and used in the material for colloid system class XI Raudhatul Ulum Indralaya High School. This development was carried out using the ADDIE model modified using Tessmer formative evaluation with stages including analysis, design, development, self evaluation, expert review, one to one, small group, field test. Data collection is done through interviews, questionnaires, tests. The validity of interactive multimedia is validated by material experts with scores obtained 0.81 very valid categories, design experts with a score of 0.94 categories are very valid, pedagogics with a score of 0.86 categories are very valid. The results of the validity score of each expert are used Aiken based calculation formula. The practicality of interactive multimedia is seen from the questionnaire assessment score in the one to one stage with an average score of 0.74 in the very practical category and the small group with an average score of 0.73 categories very practical. The effectiveness of this multimedia is seen from the learning outcomes test in the field test stage which obtained a n-gain score of 0.57 with a medium effectiveness category. The results obtained in this study are interactive multimedia that has met the criteria of valid, practical, and effective learning for chemistry of colloidal system materials.
Keywords: Development, Interactive Multimedia , validity, practical and effectiveness.
