With interactive learning media using an articulate storyline, it can help teachers in the learning process, so that learning is more interesting for students to follow. Thisjstudyjaims tojproduce ajvalid and practical Articulate Storyline learning media on optical instruments. This type of research is development research or what is known as Research and Developmentj (R&D). jThisjstudy uses the development modeljproposedjby Brag and Gall which is simplified into 5 steps, namely planning, initial product development, product validation, limited trial, and final product. The product developed was assessed by 2 material validators, namely a science subject teacher at SMP N 25 Padang and 2 media validators, namely a lecturer in the curriculum and educational technology department. The assessment ofjthe practicality test was carriedjoutjby 15 grade VIII students of SMP N 25 Padang.
