Learning mathematics through media scales of lamps from used goods

Abstract

This study aims to determine the learning of mathematics through light scales media from used goods. Students’ understanding of weight comparison is still experiencing difficulties. Students often mistakenly distinguish heavy objects from light objects. Teachers have tried to make improvements through learning methods, but only 20% of student learning outcomes have been completed. Therefore, researchers conduct action research studies in the form of treatment for learning media applications. The research subjects were 30 first grade students. Data collection techniques in this study are through observation, tests, and documentation. The results of the study prove that the use of lamp scales media of used goods in mathematics learning that is in the initial conditions, 24 students have not reached skills, but in the first cycle, the number of students who have not reached mastery decreased to 15 students and in the second cycle all students have reached completeness. This study concludes that the use of media scales lamps from secondhand goods can develop mathematical learning understanding, especially in the theory of weight comparison.
