Straight Language for the Deaf: A System of Instruction for Deaf Children
Fitzgerald's seminal work 'Straight Language for the Deaf: A System of Instruction for Deaf Children' was published in 1926 and was widely influential in the field of deaf education. Because the "Fitzgerald Key" gave additional visual support to those who had not heard language construction, it allowed students to correct their own grammar and syntax mistakes. At one time, her system was so widely used that three-quarters of the schools in the United States teaching those with hearing difficulties used it. Her book had been through nine editions by 1962.
