Abstract

. Geometry is one of the mathematical taught from elementary to high level. The importance of studying geometry is due to the many benefits and applications it offers in everyday life, namely in the fields of art, construction, computers, and so on. This research aims to develop virtual learning media to improve spatial abilities, which is one of the prerequisite abilities in studying geometry through the REACT learning model. This research is included in the type of development research with 5 stages, namely ADDIE (Analyze, Design, Development, Implementation, and Evaluate). The analyze stage is collecting data related to constraints and needs in geometric material. The design stage is creating the initial framework for learning media. The development stage is the actualization of the analysis and design stages. The implementation stage is the application of virtual media that has been validated in schools. The evaluation stage is giving tests to students as a basis for reviewing the media being developed. Research data was obtained from validation questionnaires and response questionnaires filled in by teachers, students and professionals in their fields. This development product has been assessed as valid, practical and effective in the learning carried out, producing better experimental class scores compared to control class scores without the provision of virtual Geogebra Classroom media.

Abstract

Euclid's Elements is a 13-volume textbook in mathematics and geometry written by the Greek mathematician Euclid in Alexandria, Egypt, in the early 3rd century B.C. and first published in 1482 AD in Europe. This book is a collection of definitions, postulates, theorems, and mathematical proofs of these propositions. This research aims to provide a glimpse of the history of Euclid's Elements and to determine the understanding level of junior high school students on the definition and postulates of Euclid's Elements. This research is qualitative research using literature review and case study methods. The case study was conducted on eight junior high school students, six female and two male. The instruments used in this research were analysis of several journals/articles and open interviews by asking several questions related to the definition and postulates of Euclid's Elements Volume I. The data analysis used in this research was meta-analytic and thematic. The results of this research provide information about the history of Euclid's Elements at a glance and the extent to which junior high school students know and understand the definitions and postulates contained in Euclid's Elements Volume I.
