Penerapan Pembelajaran Matematika Realistik Berbantuan Media Digital Untuk Meningkatkan Kemampuan Pemecahan Masalah Matematis Siswa Kelas VIII SMP Dharma Patra Sei Lepan

This study aims to describe the improvement of mathematical problem-solving skills after applying the realistik mathematics learning assisted by digital media of class VIII students of SMP Dharma Patra Sei Lepan for the 2022/2023 academic year. The subjects in this study were 32 class VIII-A students of Dharma Patra Private Middle School. Data collection techniques used were teacher observation sheets, tests of mathematical problem-solving skills, and documentation. This research is a classroom action research (PTK) which consists of 2 cycles, each cycle consisting of 2 meetings. Before taking action, first given the initial test and at the end of each cycle is given a test of students' mathematical problem-solving abilities. The test results of students' mathematical problem-solving abilities increased from the initial test, cycle I, and cycle II. In the classical pre-test, 3 students (9.38%) passed and the average pre-test ability was 49.12% with a very low level of ability. In the first cycle test, there was an increase classically, 17 students (53.13%) completed and the average ability test obtained 69.01% with the ability level in the medium category. Then the second cycle test also experienced an increase in classically obtained 28 students (87.5%) completed and an average ability obtained 81.05% with a high level of ability category. Thus it can be concluded that the application of realistik mathematics learning assisted by digital media can improve the mathematical problem-solving skills of class VIII students of SMP Dharma Patra Sei Lepan.
