This research aims to design and develop a Social Studies textbook using Android-based Augmented Reality (AR) Technology for the secondary school level. The research method uses a qualitative and quantitative approach with Design-Based Research. Data collection techniques use observation, documentation, and questionnaires. Qualitative data analysis uses data collection, data reduction, data presentation, and conclusions, and quantitative data analysis uses correlation regression. Research subjects are students, lecturers, and experts. The experimental results showed that implementation of social studies textbooks using Android-based AR technology is easy to visualize via cell phone. Based on expert validation, Social Studies textbooks are quite effective in Android-based AR technology. Research discussions provide evidence that the use of books is quite effective in fostering critical and creative thinking and building students' 21st-century skills. Research implications make it easier for students to visualize abstract material to become more concrete.
