Abstract

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.
