Abstract

One of the factors that causes mathematics learning at SMPLB to run less optimally is the use of teaching materials. The teaching materials used by teachers when teaching deaf children at SMPLB in Kupang City still use general teaching materials, so it is necessary to have teaching materials according to the needs and characteristics of children with hearing impairment. This study aims to produce a special mathematics book for deaf children, with the first step taken is to make teaching materials based on visualization and realistics where visual ability is their advantage. The method used is a development method with the 4D model designed by Thaiagaradjan which consists of four stages, namely, the defining stage, the design stage, the develop stage, the deployment stage. The instruments developed in this study consisted of six types, namely (1) validation of teaching materials, (2) readability of teaching materials, (3) teacher activity observation sheets, (4) student activity observation sheets, (5) response questionnaires. deaf children and (6) written test sheets. The assessment indicators of this development research include valid, practical and effective. The results of the analysis show that 24 JNPM (Jurnal Nasional Pendidikan Matematika), 5(1), 23-36, Maret 2021 © 2021 JNPM (Jurnal Nasional Pendidikan Matematika) p-ISSN 2549-8495, e-ISSN 2549-4937 the teaching materials developed meet the criteria of validity, practicality and effectiveness, so that the teaching materials are of good quality and can be used in mathematics learning for Class VII SMPLB students.
