Do teachers for the visually impaired learn sign language?
Sometimes. Sign language is for people with hearing impairments or speech impairment that require they speak using their hands. Sometimes our children with visual differences may have hearing or speech problems that require that a teacher know sign language. Sometimes people who ask confuse visual impairments with hearing impairments. Generally we think of those with vision differences as those who need large print or braille while those with hearing/speech problems need sign language to communicate. I had to learn a little sign language when working with my deaf/blind students and for some of my children who could hear but not speak.
