PENERAPAN PEMBELAJARAN MATEMATIKA REALISTIK UNTUK MENINGKATKAN AKTIVITAS DAN PRESTASI BELAJAR MATEMATIKA

This research was motivated by the low activity and achievement of students in learning mathematics which was found through initial observations of class VIII B students of SMP Negeri 3 Tabanan for the 2022/2023 Academic Year. This type of research is classroom action research using the design developed by Kemmis and Tagart. Based on the research above, whether the activity and achievement of students' mathematics learning can be increased through the application of realistic mathematics learning. This study aims to (1) determine student learning activities, (2) determine student achievement, by applying a realistic mathematics learning model. The research subjects were 32 students and carried out in 2 cycles. Data on student achievement in this study was measured using a multiple choice form of the Learning Achievement Test. The results showed that the activeness of students in cycle 1 was 3.13 in the active category and in cycle 2 it increased to 4.15 in the very active category. With an increase of 1.02 or the percentage increase in students' mathematics learning activity is 3 2.58%. The average value of students' mathematics learning achievement in cycle I was 74.03, increasing to 83.59 in cycle II. With an increase of 9.56 or a percentage increase of 12.91%. Thus it can be concluded that the application of realistic mathematics learning can increase the activity and learning achievement of class VIII B students of SMP Negeri 3 Tabanan for the 2022/2023 academic year. Therefore it is suggested to teachers of Tabanan 3 Public Middle School for the 2022/2023 Academic Year to apply a realistic mathematics learning model, and consider realistic mathematics learning models as an alternative in implementing mathematics learning (in particular) and other subjects.
