Sign language with verbal behaviorally disordered children is an alternative mode of communication for helping to maintain behavioral control. Also, fingerspelling is used to teach letter-sound association, particularly with vowels. The use of signs in the classroom reduces unnecessary conversation and expands on simple cues and signals most teacher already use. It appears that the kinesthetic value of sign language and fingerspelling assists in the educational process of remediating learning problems. Manual comunication increases opportunities for improved self esteem, attention, on-task behavior, communication, and academics. In addition, there is a motivational aspect of curiosity and novelty with the students, enhancing the purpose and results of signing.
