Development of learning media for flat-sided based on the Macromedia Flash 8 application

This development aims to produce flat-sided geometry learning media based on the application of Macromedia Flash 8 at the high school level and meets the valid category that can help teachers deliver material and assist students in understanding flat-sided geometry material in learning mathematics through learning media. To produce learning media development products for flat-sided spatial construction based on the Macromedia Flash 8 application, the researcher refers to the 4-D development model with 4 stages of development, namely: define, design, develop, and disseminate. However, due to the coronavirus pandemic situation, in this study, researchers only carried out research up to the development stage. This learning medium is equipped with instructions for use so that it is easier to operate. The final prototype of the developed learning media consists of several menu options, namely, the opening page, menu page, profile page, concept map page, competency page, material page, practice question page, and evaluation page. The validity value developed was tested for validity by validators of material experts and media experts. The results of material expert validation, with an average of 95%, are in the very valid category, while the results of media expert validation, with an average of 84%, are in the very valid category. Based on this, the mathematics learning media based on the Macromedia Flash 8 application meets the criteria for validity with a very valid category and the product is ready to be tested. © 2023 Author(s).
