Abstract

This study aims to determine the effect of implementing the Problem-Based Learning (PBL) model on the learning outcomes of fourth-grade students at SDK Waipanda in Natural and Social Sciences (IPAS). The study used a quantitative approach with a pretest–posttest control group design. The sample consisted of 20 students selected purposively, namely 10 students in the experimental class and 10 students in the control class. The research instrument was an IPAS learning outcome test consisting of 15 multiple-choice questions that had been validated. Data collection was conducted through pretest and posttest, then analysed using normality test, homogeneity test, and t-test. The results showed that the average pretest score of students was 41.00 and increased to 56.75 on the posttest. The t-test confirmed a significant difference between learning outcomes before and after the implementation of the PBL model with a significance value of < 0.05. These findings indicate that the PBL model has a positive effect on the learning outcomes of Grade IV students in IPAS. Thus, it can be concluded that the implementation of Problem Based Learning can improve student learning outcomes and is suitable as an alternative in IPAS learning in primary schools.

Abstract

The purpose of this study is to determine the mathematical elements contained in woven fabrics at the Ori Angu Waingapu Art Studio. This type of research is descriptive qualitative. The subjects in the study were two cloth traders at the Ori Angu Waingapu Art Studio and the object of the research was Ethnomathematics in Woven Fabrics at the Ori Angu Art Studio. The instruments used in this study were observation sheets, interview sheets, field notes and documentation. The research data analyzed were qualitative research data carried out through three simultaneous activity flows, namely data reduction, data presentation, and conclusion drawing. The results of the study were to find mathematical elements in algebraic form, namely the number of images contained in woven fabrics and more using the formula for the area of a rectangle (P) times the width (L) to calculate a collection of images arranged regularly on woven fabrics. So this discovery got two things, namely using algebraic formulas and rectangular area formulas.
