PENINGKATAN KEMAMPUAN MENGOLAH DAN MENGANALISIS DATA SEDERHANA MELALUI MEDIA ULOSDATA PADA PESERTA DIDIK KELAS IV SD TEGAL SARI

Abstract

This study aims to describe the improvement of fourth-grade students’ ability to process and analyze simple data through the use of ULOSDATA (Jelajah Data dalam Motif Ulos). The learning activity was conducted at SD Tegal Sari involving 19 fourth-grade students. The learning process used the Problem Based Learning (PBL) model supported by ULOSDATA, which presents simple data processing activities through the cultural context of Batak Toba ulos. The media consists of Ulos Motif Cards, Data Pieces, a Tally Board, a Data Table Board, a Bar Chart Board, HOTS Challenge Cards, and Ulos Information Cards. Data were collected through written pretest and posttest instruments administered before and after the learning activity. The assessment focused on students’ ability to identify information from data, read and interpret tables or bar charts, compare data, determine the highest and lowest values, calculate differences, analyze changes, evaluate statements based on data, and draw conclusions. The results showed an increase in students’ learning outcomes. The average pretest score was 55.79, while the average posttest score increased to 85.26, resulting in an average increase of 29.47 points. These findings indicate that learning activities using ULOSDATA were followed by an improvement in students’ ability to process and analyze simple data.
