Abstract :
This study aims to produce a product in the form of learning media based on macromedia flash on the material for transformation of class IX SMP which has been tested for validity. The development model ini this study uses the ADDIE development model which was modified due to the covid-19 pandemic, which consists of the Analysis, Design and Development stages. The data collection technique used in this study was a non-test technique and the data collection instrument was a media validation sheet filled out by 3 validators. The data analysis technique used is descriptive data analysis. From the research result obtained validation results from all validators with an average 0f 90,94% with very valid category. From the result of the research, a macromedia flash based mathematics learning media has been produced on transformation material that has been test for validity.
