Title IV - Telecommunications
Prior to the ADA, those who were blind, deaf or dumb had major challenges with communication. Today services like text telephone (TTY/TDD) have opened up the world to the hearing impaired. The hard of hearing or speech impaired can use these services to communicate by typing messages which are then relayed and received back in a way they can understand. Closed captioned TV has allowed those with hearing disabilities to keep up with current events or watch their favorite shows without lip reading. Computer generated relay services also allow communication through the internet and even your smart phone will allow hands-free communication through both visual and audio means. Communication is different, much different.
Here is another example of a simple error of omission that could have been caught if the student had read the essay aloud or given it to a friend to read. The word "of" should be between "calculation" and "the." That one small error makes the entire sentence awkward and confusing. If the instructor has to reread the sentence to try to understand its meaning, the flow of the essay is interrupted. If this happens often enough in the essay, it gives an overall bad impression on what otherwise might be a very good paper in terms of research.
