Improvements of Tabletop Model of Internal Organs for Anatomy Learning of the Visually Impaired

This study established an enhanced tabletop model of internal organs designed to anatomy learning for students with visual impairments. We implemented several modifications to the model presented in 2022. These included adjusting the color scheme of the respiratory system components, correcting the positional relationship between the pancreas and stomach, and modifying the shape of the large intestine. Unlike the previous model, which did not incorporate magnets to connect or fixate organs, this updated model integrates this feature. As a result of these modifications, we have developed three variations of the model: Model-A, which does not use magnets to connect and fixate organs; Model-B, which employs magnets solely for fixation purposes and not for connectivity; and Model-C, which uses magnets for both organ connection and fixation. The results of the evaluation experiment revealed that Model-B serves as a superior instructional tool in terms of operability.
