The Development of A Braille Geometry Module Based on Visual Impairment Students Synthetic Touch Ability With RMT Approach

摘要

This research aims to develop a Braille geometry module based on visual impairment students synthetic touch ability with RMT approach that was valid and practically using ADDIE development design. This module optimizes students' synthetic touching ability and develop RMTs three cognitive functions i.e., the cognitive function of qualitative thinking, quantitative thinking with precision, and abstract relational logic thinking. A media experts and material experts validated the module. The student' response questionnaire measurement the practicality of the module. Data were analyzed using descriptive quantitative. The results showed the validity of the geometry Braille module from material and media experts that showed module validity average in 86, 1%. Some revisions are needed, especially on the representation of the quadrilateral model which needs appropriating to students' physiological and structural abnormalities. Based on data collected from small-scale and large-scale students who have completely filled 10 statements in the questionnaire, shows that students response assessment validation score is included in category "very good". Thus those results indicated a high level of practicality. This result research showed that the module has good validity and practicality, especially for visual impairment students' geometries object understanding that has limited visualization.
