The use of three-dimensional media in the shape of the Earth’s surface to optimize the knowledge of blind students in social science subjects

The aims of this research are to (1) produce three-dimensional (3D) media suitable for use and (2) analyze responses and learning outcomes for blind students who use 3D media in the Earth’s shape. The subjects of this study included 16 blind students in class VII SMPLB-A Gebang Putih Surabaya and SLBN Kalirejo Bojonegoro, East Java Province, Indonesia. The feasibility level of the media is based on assessments from learning media and material experts using validation sheets from media experts and material experts. They collect data on the responses of blind students using student response questionnaires. Collecting data on learning outcomes of blind students uses tests carried out through pre-test and post-test activities. The media feasibility data analysis technique uses a four-category Likert-type scale adopted from Mardapi. The responses of blind students were analyzed using a five-category Likert-type scale adopted from Sugiyono. Learning outcomes were analyzed using the n-gain test and paired sample t-test. The study results stated that 3D media in the form of the Earth’s surface received a feasibility assessment by learning media experts in the very feasible category. The blind students responded very well to using 3D media in the form of the Earth’s surface in social science subjects. In the aspect of knowledge in the form of learning outcomes, it has high effectiveness, and there is a significant difference between before and after applying 3D media in the shape of the Earth. Through 3D media, Blind students can experience visual experiences using 3D media. By holding and touching objects in 3D media, they can feel their shape, size, and texture.
