Abstract

This study was a research and development used ADDIE model aimed to produce mathematics textbook for 8th-grade students by applying five principles of the Realistic Mathematics Education (RME) approach, included: phenomenological exploration, bridging by vertical instruments, self-reliance with students own constructions and productions, interactivity, and intertwining. The subject in this study involved 30 students' junior high school in Yogyakarta. The qualities of the developed textbook refer to three criteria, namely validity, practicality, and effectiveness. Supporting instruments used to examine three criteria for the quality of the textbook were validation sheets, assessment sheets for teachers and students, and students' mathematical communication ability test. The textbook meets the criteria of validity, practicality, and effectiveness if at least "good" from the results of validator assessments, the results analysis from teachers and student assessments, and at least 75% of the students' mathematical communication ability test results. Based on the results of this study, the developed textbook has met the criteria of validity (very good), practicality (very good by the teacher and good by students), and effectiveness (good for 86.67%). Therefore, developing textbooks is suitable to use as an alternative to enhance the students' mathematical communication ability.

Abstract

This study aims to design an Android-based Flat and Spatial Geometry Augmented Reality Application in primary school (SD, Sekolah Dasar) that is valid and practical. This application uses the Vuforia library which is capable of playing sound and displaying animated 3D objects, played by the user in a real environment using the help of books and Android-based smartphones. This research is a Research and Development (R&D) study using the ADDIE model (Analysis, Design, Development, Implementation and Evaluation) to develop Flat and Spatial Geometry Augmented Reality Applications in Elementary Schools as a learning medium that is expected to be able to create a fun and effective learning environment to improve students' mathematical literacy ability. The research subjects were 32 students of class VI at SD Negeri 050660 Kwala Bingai Stabat. The research instruments used in this study included validation sheets to obtain an assessment of the validity of the application, and student response questionnaires to determine the practicality of the application. The results of the research and development show that the Application of Augmented Reality Flat and Spatial Geometry is in very good criteria. The results obtained based on the analysis of the black box test obtained a success percentage of 100% and the white box test obtained a success percentage of 100%. While the average validation score is 90.19% of the total interpretation. In the field test, it was obtained an average practicality percentage of 84.5% from 15 assessment items. So that the application of augmented reality flat geometry and space is included in the very good criteria.
