RESUMO
The phenomenon of the Industrial Revolution 4.0 currently emphasizes rapid technological advances. There is a need for innovation in technology development to package the current learning process more effectively, one of which is the development of learning media which is an important part of the learning process and is certainly directed at meaningful learning that encourages students to develop 21st Century skills as an urgency in the field of education. This study aims to 1) Develop interactive learning media with an articulate storyline based on a case method on cellular respiration material. 2) Look at students' responses to the interactive learning media articulate storyline based on the case method on cellular respiration material in training students' problem-solving skills. This research is a Research and Development (R & D). The development model in this study uses the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model, this research was carried out until the Development stage. The instruments used in this study were an open questionnaire sheet, material aspect validation sheet, media aspect validation sheet and pedagogic aspect validation sheet. The analytical technique used is descriptive qualitative analysis technique and quantitative analysis by finding the average score obtained from the validator's assessment and looking at the criteria. The results of this study obtained a very valid interactive learning media with a score of 3.9 material expert validators in the very valid category, 3.69 media expert validators in the very valid category, pedagogical expert validators of 3.47 in the valid category. It can be concluded that the articulate storyline interactive learning media based on the case method developed can improve students' problem-solving abilities.
