Development of GeoGebra-Based Fraction Gap Learning Media to Improve Understanding of the Fraction Concept of Grade V Elementary School
Main Article Content
Abstract
Students need mathematics to solve everyday problems with fundamental technological developments. Technology-based media greatly supports success in mathematics learning, especially for elementary school students. This study aims to develop GeoGebra-based Fractional Gap learning media that is feasible in improving the understanding of the concept of fractions of grade V elementary school students. The implementation of this research uses the Research and Development (R&D) method with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). Data collection techniques include interviews, observation, expert validation, and pretest-posttest tests. The study was conducted on V-A and V-C class students at SD IT Al-Falaah Sambi, totalling 40 students. The results of the media feasibility test amounted to 4.59, including the " Very Good " criteria; the material feasibility test amounted to 4.18, including the "Very Good" standards; and the feasibility test from practitioner validation amounted to 5, including the "Very Good" criteria. Product effectiveness tests were conducted using pretest-posttest test questions in experimental and control classes. The hypothesis test results obtained a probability of significance of 0.022 < 0.05, meaning that students' understanding of the concept of fractions increased. From the study results, it was concluded that GeoGebra-based Fractional Gap learning media is feasible and practical to be applied to improve the understanding of the concept of fractions of grade V elementary school students.
