Deaf children have significant difficulties in comprehending written text. This is mainly due to the hearing loss that prevents them from being exposed to oral language when they were an infant. However, it is also due to the type of educational intervention they are faced with, which accustoms them to decoding single words and isolated sentences, rather than entire texts. This paper presents an evolved version of a literacy web tool for deaf children based on stories and comprehension exercises. Two substantial improvements were made with the respect to the first version of our application. First, the text of the stories is now presented to children in the context of "animated" web pages. Second, "intelligent dynamic feedback" is given to the users when resolving the exercises. A preliminary evaluation study with deaf children, as the treatment group, and hearing children, as the control group, assessed the usability and effectiveness of the new system and its graphical interface.
