Pengembangan Multimedia Interaktif Berbantuan Geogebra untuk Menumbuhkan Literasi Numerasi Kelas IV Sekolah Dasar

Abstract

Learning Media greatly affects student learning outcomes. This research is motivated by the fact that the learning media used by teachers has not been maximized so that students' numeracy literacy has not grown and there are still many teachers who are not familiar with Geogebra learning media. The research was carried out at SD Negeri Sumberejo 1, Bonang District, Demak. The subjects of this study are Grade IV Elementary School Teachers spread across Central Java Province as many as 17 respondents and Grade IV students of SDN Sumberejo 1 with a total of 23 students. This study uses the R&D method with ADDIE steps which consists of five stages which include analysis, design, development, implementation and evaluation. Data processing was taken from the results of initial observation of the research, validation of media experts and material experts and student learning outcomes. The results of observations made by researchers using google forms as many as 17 respondents of grade IV teachers spread across Central Java Province showed that 52.9% of students' numeracy literacy was still lacking, the subjects that were most experienced by students were mathematics learning with a percentage of 70.6%, while the media used by teachers to overcome these problems included storybooks, pictures and videos,  fragment boards, sticks, chalkboards, and more. The results of media validation with a percentage of 95% and material validation show a percentage of 95% with the interpretation of product feasibility showing that it is very feasible. The conclusion obtained from this study is that the development of interactive multimedia assisted by geogebra to foster numeracy literacy in grade IV elementary school has been effective, which can be seen from the learning results showing that students have completely achieved above the KKM, namely 23 students with an average score of 83.
