Abstract
The dimension-expanded 3D printing art appreciation teaching aid developed in this study is a 3D printer that layers famous paintings that have been unable to appreciate touch due to their flat shape in the order of “background, sub-topic, and subject.” In other words, unlike the method of putting famous paintings on a single layer, it was organized to facilitate understanding of the concept of dimension by separating people, objects, and spaces for each layer. As a result of applying it to two blind schools over a total of three years from 2020 to 2022, students with starting disabilities can understand that famous paintings, which have been composed in a flat form, were produced through the principle of stacking and accumulation. This understanding of masterpiece production made it possible to have an interest in the artist and the times at the time, confirming that this parish could be used as a literacy cultivation tool for blind children to understand the world. In particular, the developed teaching aids and textbooks were evaluated to be able to meet the timeliness and necessity in the special education field as they were provided as auxiliary media for educational programs based on demand.
