BRAINO – Braille Domino (Fraction Series) as Learning Media for Visually Disabled Students

Abstract

The background of this research is limitations of mathematics learning media for visually disabled students, especially in fraction basic operations. The purpose of this study was to develop learning media Braille Domino (BRANO) fraction series. This research was conducted at SLB A Pembina Jakarta National with two students of class VII A and four students of class VIII A as the research subjects. This research used research and development model or commonly called Research and Development (R&D) with the stages of ADDIE development (Analysis, Design, Development, Implementation, Evaluation). The research instruments used were questionnaires and interviews. The questionnaire consists of a media validation questionnaire and a material validation questionnaire which used to determine validity of the product, as well as a teacher response questionnaire to determine practicality. The interviews consisted of interviewing student responses which were also used to find out practicality. The results showed that BRAINO media in the fraction series was declared very valid with an average score of 4.52 for media experts and an average score of 4.41 for material experts. The results of student responses in the 1^st stage trial obtained an average score of 3.72 in the practical category, while the teacher's response obtained an average score of 4.50 in the very practical category. The results of student responses in the 2^nd stage obtained an average score of 4.66 in the very practical category and for teacher responses obtained an average score of 5 in the very practical category. Thus it can be concluded that the learning media Braille Domino (BRAINO) fraction series for blind students is declared valid and practical to use. The results of this study are expected to be useful for related parties such as teachers, blind students and future researchers.
