The academic achievement of deaf students is still far below that of their hearing peers. There is not one explanation for this struggle, but two facts that contribute to this poor achievement are the speed of information being given and the problem with line-of-sight communication. Line-of-sight communication is a type of communication that relies mostly on the visual domain. Research has implied that only about half the information that is communicated by speech can be communicated by sign. This study focuses on the amount of time that communication is possible in a classroom for the deaf.
