Augmented Reality-Based Pop-Up Book for Teaching Rupiah Currency Recognition to Deaf Junior High School Students

Deaf students depend heavily on visual input, yet Indonesian special schools still teach currency recognition mostly with flat textbook pictures. This study aimed to develop an augmented reality-based pop-up book on the value, colour, and imagery of Indonesian Rupiah currency for deaf students at a special junior high school and to examine its feasibility and preliminary effect on learning outcomes. A research and development design based on the Analysis, Design, Development, Implementation, and Evaluation model was applied. The product pairs a printed pop-up book with scannable markers that show three-dimensional models of nine Rupiah banknotes and coins. Two content experts rated feasibility using an 18-item, five-point instrument, and eight deaf students at a state special school in Bogor, Indonesia, joined a one-group pretest–posttest trial analysed with normalised gain. The experts’ ratings yielded a feasibility percentage of 90%, in the very feasible category. Mean scores increased from 47.25 to 79.63, with a mean normalised gain of 0.62, and every student fell in the medium gain category. The medium is feasible and shows early promise for supporting currency recognition among deaf students, although a larger controlled study is required.
