The Effectiveness of Using Problem Based Learning Models Assisted by VISIJAKAR Etnoscience Media in Understanding Natural Science Concepts

Abstract

This study was motivated by the low level of IPAS concept understanding among fourth-grade students at SD Kedungbulus 02. The purpose of this study was to analyze the effectiveness of the Problem Based Learning (PBL) model assisted by ethnoscience-based VISIJAKAR media in improving students' understanding of IPAS concepts. This study employed a quantitative approach using a one-group pretest-posttest design. The research subjects consisted of 28 fourth-grade students. Data were collected through pretests and posttests. The data were analyzed using the normality test, paired sample t-test, and N-gain test. The results showed a significant difference between the pretest and posttest scores. The paired sample t-test showed a significant difference between pretest and posttest scores (p < 0.05). Furthermore, the N-gain test produced a score of 0.6337, which was categorized as medium, with a gain percentage of 63.37%, indicating that the learning model was moderately effective. Therefore, the Problem Based Learning model assisted by ethnoscience-based VISIJAKAR media was moderately effective in improving students' understanding of IPAS concepts.
