Implementation of Braille Code Coordinate Board Media in Learning Mathematics of Cartesius Coordinate Systems for Visual Impairment Students
Abstract.The purpose of this study was to study student achievement in studying the material of the Cartesius coordinate system using a braille-coded coordinate media. This type of research is a single subject research (SSR) reversal design A-B which consists of two phases, namely the baseline phase and the intervention phase. The methods used to collect data are interviews, learning achievement tests, and documentation. The instrument used was interview guidelines and test questions. Data analysis techniques with descriptive statistical analysis. The results of the analysis in the conditions at the baseline phase obtained a change of +2, and the conversion phase obtained a change of +14. The results of analysis between conditions obtained by data overlap by 0%. This is a very good phase of change. By using braille-coded coordinate media, visual impairmentstudents can order materials for the Cartesius coordinate system more easily.Keywords: mathematics learning, learning media, braille, and visual impairment.
