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

摘要

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 7th 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 user-friendly levels between mathematics Braille and audiotac book uses had significant difference.
