Development of interactive multimedia using Adobe Flash based on problem solving in trigonometry learning

Interactive multimedia is very important in learning, to help students learn mathematics so that they can learn independently, more easily understand and be motivated to learn. The purpose of this research describes the development of interactive multimedia using Adobe Flash CS6 based on problem-solving in learning trigonometry. This research was conducted in Indonesia. The research method used was the Research and Development (R&D) with the Analysis, Design, Development, Implementation and Evaluation (ADDIE) model. The research subjects were mathematics education experts, interactive multimedia experts, and 6 high school students. To test the feasibility of interactive multimedia, data were collected using the form of content validity, face validity, and questionnaires. Content validity measures the suitability of a concept with the curriculum syllabus and problem-solving. Meanwhile, face validity is more likely to measure performance style. The data collected were analyzed qualitatively. The results showed that interactive multimedia using Adobe Flash- based on problem-solving in Trigonometry learning was suitable for use as interactive multimedia in mathematics learning. The limitations of this research, which was carried out in the era of the Covid-19 pandemic, did not reach the implementation in the classroom but only limited trials with 6 students.
