One of the pedagogical problems encountered by Special School (SLB) Teachers in teaching deaf students is the difficulty in teaching communication and language skills. Deaf students, especially those who are just learning in early grades of elementary school, faced three problems, namely not being able to hear, not being able to pronounce words verbally, and also not understanding sign language. It is not easy for teachers to teach communication skill and language ability to deaf students. Therefore, it is necessary to find a solution, by identifying the teachers' pedagogical problems in teaching deaf students. The purpose of this study was to identify the pedagogical problems faced by special school (SLB) teachers in teaching communication skill and language ability for deaf students. This research is a survey research at SLBN Semarang, SLBN Purbalingga, and SLB Swasta YRTRW Surakarta involving 33 teachers as research subjects who were selected purposively, namely SLB teachers who have direct experience in teaching in a class for deaf students.
