PENINGKATAN PEMAHAMAN KONSEP MATEMATIKA MATERI SATUAN PANJANG MELALUI MEDIA TANGGA PINTAR PADA PESERTA DIDIK KELAS III DI SD BAWAMAI PONTIANAK

Abstract

This study aimed to improve students’ understanding of mathematical concepts related to units of length through the use of Tangga Pintar (Smart Ladder) media. The study employed a Classroom Action Research (CAR) method based on the Kemmis and McTaggart model, conducted in two cycles consisting of planning, action implementation, observation, and reflection. The subjects were 24 third-grade students at SD Bawamai Pontianak. Data were collected through observations, tests, and documentation and analyzed using descriptive quantitative and qualitative techniques, including mean scores, learning mastery percentages, and analysis of student activity observations. The results showed that the students’ mean score increased from 63.12 in the pre-cycle to 74.16 in Cycle I and 86.04 in Cycle II. Learning mastery also increased from 37.5% in the pre-cycle to 70.8% in Cycle I and 87.5% in Cycle II. In addition, students’ learning activities and engagement also improved throughout the learning process. Therefore, Tangga Pintar media was effective in improving third-grade students’ understanding of mathematical concepts related to units of length at SD Bawamai Pontianak. These findings indicate that concrete and visual learning media can facilitate students’ understanding of mathematical concepts in elementary education.
