The Use of Manipulative Media to Enhance Concept Understanding in Area Measurement Using Non Standard and Standard Units among 4th Grade Students at SD Negeri 2 Lawang

Abstract

At SD Negeri 2 Lawang, the process of teaching Mathematics is still often presented in the form of lectures. This causes students to be passive and have difficulty understanding a mathematical concept. To address this, the necessary step is to use appropriate learning media so that students can think critically, logically, and solve problems with an open, creative, and innovative attitude, especially in learning the material on Area Measurement using Non-Standard and Standard Units. This research aims to improve the ability to understand the concept of Area Measurement using Non-Standard and Standard Units through the use of Mathematical Manipulative Media. This research is a classroom action research using a qualitative approach conducted through two cycles.The sample for this research consists of 28 fourth-grade students from SD Negeri 2 Lawang, comprising 12 male students and 16 female students.The instruments used in this study are tests, observations, and documentation. The research results show that there is an improvement in students' conceptual understanding of Area Measurement with Non-Standard and Standard Units using Manipulative Media, as evidenced by the increase in students' learning outcomes. This research shows that the use of Mathematical Manipulative Media in the material of Area Measurement with Non-Standard and Standard Units has proven effective in improving students' conceptual understanding and learning outcomes.
