Pengembangan Media Pembelajaran Kartematika Berbasis Aplikasi Android Untuk Memfasilitasi Kemampuan Pemahaman Matematis Siswa Kelas VIII SMP/MTS Pada Materi Koordinat Kartesius
Students’s low mathematical understanding abilities are caused by the lack of learning media innovation at school, especially in cartesian coordinate subject. The goal of this research is to create a learning media called "Kartematika" based on an Android app to facilitate student’s mathematical understanding abilities in a valid and practical manner. Development research uses the 4-D model (Define, Design, Develop, Disseminate). Data collection instruments include validation sheets and student response questionnaires. The data analysis technique used is validity and practicality analysis. The result of validation of the learning medium was 93.6% with very valid criteria. The learning media passed the validation with a score of 93.6%, meeting the highly valid criteria. In a small group test, it proved to be very practical with a score of 91.4%, and in a large group, it was still highly practical at 89.6. The analysis concludes that the "Kartematika" learning media for cartesian coordinates meets the standards for both validity and practicality.
