PENGEMBANGAN GAME EDUKASI "KUBISA" BERBASIS ALJABAR GEOMETRIK PADA MATERI KUBUS MENGGUNAKAN MODEL ADDIE UNTUK MENINGKATKAN PEMAHAMAN KONSEP DAN KETERAMPILAN APLIKATIF PADA MATA KULIAH KAPITA SELEKTA PENDIDIKAN MATEMATIKA

Mathematics can be the basis for the development of modern technology and can encourage the development of student thinking. With mathematics learning, it is hoped that they will be able to understand concepts and apply them, thus making students able to think competitively. Therefore, it is necessary to develop an educational game called "Kusa" which is directed at the cube material. With this educational game, it makes it easier for students to understand concepts and apply skills. The method used in this study is the Research and Development (RnD) method.After the development was carried out, trials were first carried out on students, such as readability tests and game tests with development stages, namely first defining the needs in the field, then designing the game instruments that would be used and the process of making the Kubisa game based on geometric algebra on cube material.Statistically, the t-stat value is -15.03 and the p-value is far below 0.05, indicating that the difference between the pretest and posttest results is statistically significant. Questionnaire Analysis Results: A satisfaction questionnaire was used to determine students' responses to the math domino game learning media. Fifty-four percent of students rated this method in the "Good" category, and 46% rated it in the "Very Good" category. No students gave ratings in the "Enough" and "Poor" categories. This indicates that the math domino game was very well received by students
