SUMMARY
This study aims to find out the ability to compose sentences of deaf children in outstanding schools. This study was conducted using qualitative case study method in the form of interviews and documentation studies of students' learning outcomes, interviews were conducted on 14 elementary school teachers. This research was conducted by two schools, namely in SLB-B YRTRW and SLB YAAT surakarta. The results showed that deaf children have problems in composing sentences and understanding the meaning of sentences. This is due to, 1) the receptive ability of children who are hampered by hearing ability, 2) the interest in learning deaf children in indonesian language is low, and 3) the use of non-standard sign language systems in communication between deaf children in activities outside the classroom. According to the class teacher, most deaf children also think that indonesian language is a difficult and boring lesson. Therefore, teachers need to increase innovation and creativity in the delivery of Indonesian language materials to be more interesting, either by using media or props that are fun and worth using to increase the motivation of learning deaf children and help the understanding of materials composing Indonesian sentences.
