The Difference of User-Friendly Level Between Mathematic Learning in Blind Students Using Braille Book and Using Audiotactual Book

Abstract

This research is aimed to examine the difference of user-friendly level between the students who learning mathematics with Braille book and those with audiotactual (audiotac) book. The research design employed in this research was quasi experiment-Posttest-Only Control Design. The population of research was the 7 th blind graders throughout Indonesia. The sampling technique employed was purposive sampling. The subject of research consisted of 38 students affiliated in 8 SLBs (Special Schools for Disabled Students) in 6 provinces in Indonesia. Techniques of collecting data used were questionnaire and test. Instrument validation was carried out using content validity, while reliability test was conducted using inter-rater technique. Technique of analyzing data used in this experimental study was t-test data analysis. The result of research showed that t statistic was-4.955 at sig. 0.00 meaning that there was a significant difference of user-friendly level between the use of Braille and audiotac books. The mean difference of Braille and Audiotac book uses was-12.016-5.036. The easiness of learning using Braille book is different from that using AUDIOTAC book, with the difference of mean score of 8.527 (36.684-28.157), so that it could be concluded that the userfriendly levels between mathematics Braille and audiotac book uses had significant difference.
