Peningkatan Pemahaman Aturan melalui Problem-Based Learning Berbantuan Media Kotakku

Abstract

This study aims to describe the improvement of fourth-grade students' understanding of rules in home, school, and community environments, measured through learning outcomes, using the Problem-Based Learning (PBL) model assisted by the Kotak Aturanku (Kotakku) media.

This study employed a descriptive quantitative approach using classroom action research based on the Kemmis and McTaggart model. The study involved 23 fourth-grade students at SDN 020 Lengkong Besar, Bandung, during the 2026/2027 academic year. The research was conducted in three cycles, each consisting of one meeting. Data were collected through essay-form pretest and posttest and analyzed descriptively by calculating mean scores and classical mastery percentages.

The mean posttest score increased from 66.54 in Cycle I to 72.17 in Cycle II and 83.38 in Cycle III, while classical mastery increased from 17.39% to 43.48% and 86.96%. The success criterion of at least 80% classical mastery was achieved in Cycle III. Because the focus and test items differed in each cycle, the gains describe progress across the sequence of actions rather than comparisons on equivalent instruments.

PBL assisted by Kotakku was associated with improved understanding of rules, as indicated by learning outcomes that met the classical mastery criterion in Cycle III. Without a comparison group, the findings do not establish causal effects and call for further quasi-experimental research.
