Design of Mathematics Learning Media Using Genially Combined Quizwhizzer Platfrom for Class X Senior High School Students

This study aims to develop and evaluate the effectiveness, practicality, and validity of learning media in improving student academic achievement. The method applied is R&D (Research and Development) by adopting the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research findings indicate that the Genially platform- based math learning media combined with Quizwhizzer is declared Valid, based on the assessment of material experts and media experts. Practicality test shows good results, seen from student observation sheets and teacher observation sheets. Meanwhile, the effectiveness of the media in improving math learning outcomes is said to increase. In conclusion, the development of mathematics learning media using a combination of the Genially platform and Quizwhizzer proved to be very effective in improving students' understanding of quadratic equation material.
