PENERAPAN MODEL DISCOVERY LEARNING BERBANTUAN MEDIA MATOKA (MATEMATIKA BONEKA) UNTUK MENINGKATKAN PEMAHAMAN KONSEP DASAR ARITMATIKA SISWA KELAS I SD NEGERI TANJUNGREJO 1

Abstract

Ideally, mathematics learning in early grades uses concrete object manipulation. However, in grade I of SD Negeri Tanjungrejo 1, 40% of students have not achieved the minimum mastery criteria (KKM) in understanding basic arithmetic concepts due to reliance on passive digital media (PPT and video). This study aims to describe the improvement of basic arithmetic concept understanding through the application of the Discovery Learning model assisted by MATOKA (Matematika Boneka) manipulative media. The research method used is Classroom Action Research (CAR) based on the Kemmis and McTaggart model, conducted in two cycles with 28 first-grade students as subjects. Data collection techniques included evaluation tests and learning activity observation. The results showed a significant improvement. The data recorded an increase in the class average score from 62 in the pre-cycle, to 71 in Cycle I, and reaching 83 in Cycle II. The percentage of classical completeness also increased sharply from 60% to 89% at the end of the action. Based on these results, it is concluded that the collaboration of the Discovery Learning model and MATOKA media is highly effective in improving students' understanding of basic arithmetic concepts.
