Why is the play called "The Miracle Worker"?

The play is called The Miracle Worker because Annie Sullivan worked a miracle when she not only taught Helen Keller to communicate but also when she brings the Kellers closer to each other. Helen's entire family thought that teaching her was hopeless. They had pretty much given up on her ever being able to live a normal life. Sullivan, however, believed otherwise. She refused to give up on Helen because, in a sense, she would be giving up on herself. Sullivan's persistance opened up the lines of communication with Helen and showed her a new world. Mr. Keller was very uncommunicative and harsh toward his son James. Sullivan is the only one who stands up to his harsh criticism and eventually she makes him realize that he has become a hard man. Sullivan also made James realize that he was a man and had the ability to stand up to his father's criticism. Sullivan worked a miracle with the entire Keller family. She believed not only in Helen but also in herself, and because of this belief, a miracle occured.
