Pengembangan Buku Ajar dan Augmented Reality pada Konsep Sistem Eksresi di Sekolah Menengah Atas

Abstract

The research was a Research and Development (R&D). The development model was 4D
development model which consists of four activity stages, namely: 1) define, 2) design, 3)
development, and 4) dissemination. The research aimed to produce a textbook and an Augmented
Reality which are valid, practical, and effective. The assessment instruments consist of three items,
namely 1) validity instrument in a form of validity assessment instrument of textbook and
Augmented Reality, 2) practicality instrument in a form of teachers and students’ responses
questioner on textbook and Augmented Reality, 3) effectiveness instrument in a form of students’
learning outcome evaluation test. Based on the data analysis, the average validity of the textbook
and Augmented Reality by two expert assessors was 4.24 (valid) and 4.3 (valid), respectively.
Media practicality of the text book and Augmented Reality based on teachers’ responses was 4.4
(high) and 4.1 (high), respectively. Media effectiveness score was 89% students reached the
learning completeness score. Based on the result of the research, it could be concluded that
textbook and augmented reality that were developed were valid, practical, and effective.
