Abstract

Mathematics is one of the important subjects in elementary school learning. The understanding of addition concepts among second-grade students at SD 2 Karangbener still needs to be improved because some students experience difficulties in understanding addition concepts and solving given problems. This study aims to improve the addition concept understanding of second-grade students at SD 2 Karangbener through the implementation of the Indonesian Realistic Mathematics Education (PMRI) approach. This study employed Classroom Action Research (CAR) conducted in two cycles with three meetings in each cycle. Each cycle consisted of planning, action, observation, and reflection stages. Data were collected through tests, observations, interviews, and documentation. Data were analyzed using quantitative and qualitative analysis. The results showed an improvement in students' understanding of addition concepts. The average learning score increased from 44.29 in the pre-cycle to 69.64 in Cycle I and 80.36 in Cycle II. Classical completeness also increased from 14.29% in the pre-cycle to 42.86% in Cycle I and 78.57% in Cycle II. Student activity increased from 75% in Cycle I to 85% in Cycle II. Thus, the implementation of the PMRI approach can improve the understanding of addition concepts and student activity among second-grade students at SD 2 Karangbener.
