Perbedaan Pemahaman Konsep Matematika Siswa Pada Model Pembelajaran Blended Learning Antara Yang Dibelajarkan Menggunakan E-Learning Melajah.id Berbantuan Aplikasi Geogebra Dengan E-Learning Konvensional

This research purpose to determine whether or not there are differences in students' understanding of mathematical concepts in the Blended Learning learning model between those taught using E-Learning Melajah.id assisted by the Geogebra application and conventional E-Learning. This research method is a qualitative method. This type of research is experimental. The research design used is the Posttest-Only Control Group Design. The data was collected by means of tests, interviews, observation and documentation. The subjects of this study were students of class XI MIPA SMA Negeri 1 Abiansemal with a total of 285 students. The research sample was selected using the Cluster Random Sampling method so that the number of samples for this study was 72 students. The material used is Geometric Transformation material. The data analysis technique uses Prerequisite Test, namely normality test, homogeneity test and hypothesis testing. The average student learning outcomes of the control group was 81.61, while the average student learning outcomes of the experimental group was 86.11. The posttest results show that is 2.16>1.67. So, it can be concluded that is rejected and is accepted. In other words, there are differences in students' understanding of mathematical concepts in the Blended Learning learning model between those taught using E-Learning Melajah.id assisted by the Geogebra application and conventional E-Learning.
