This presentation will discuss two studies using computer-assisted instruction with digital stories to teach expressive writing to secondary students with disabilities. One study focused on students with autism, and the other involved those with learning disabilities. "PhotoStory" of Microsoft in the Windows platform was used to allow learners to post, crop, move and rotate digital pictures, typing texts, and recording voices, in order to produce a story in a slideshow format. As a result, students learned writing skills to develop their compositions to increase the length, correct words and sentences, and improve quality of writing.
