Effectiveness of Audiotactual Media on Mathematics Learning in Blind Students

Abstract

The study aims to determine the effectiveness of audiotactual media on the independence aspects of learning mathematics in blind students. The approach used in this research is quantitative research. The design of this study uses a randomized posttest-only comparison group, consisting of 2 groups, namely groups of students using Braille mathematics media and groups of students using tactual audio mathematics media. This research was conducted in nine special blind schools from six provinces in Indonesia. Determination of the subject carried out random sampling. Data collection techniques using a questionnaire. The validity of research instruments uses content validity, while the reliability of research instruments uses interrater analysis. Data analysis using quantitative data analysis is the t-test. This study concludes that the use of audiotactual mathematics media is more effective than Braille mathematics media on the independence of blind students.
