The Lexington School for the Deaf (New York) has developed a program which involves deaf students in extensive writing within the science curriculum through utilization of a local area network of linked computers. The program is intended to counter the students' low science achievement and poor written language skills. Originally developed for use in the pre-highschool Earth Science curriculum, the technology was used during 1990 with 10 deaf children (median reading grade level 4.1) in a high school preparatory class. Students used the computers to communicate with the teacher and to complete assignments including logs, summaries, reports, problem solving, story completion, filing, tests, and short-answer quizzes. Several writing measures were used to evaluate children's writing samples: a measure of writing errors, a measure of connectedness in writing, and a number of holistic measures. Analysis of changes in student writing indicated a significant reduction in writing errors and in failures to connect sentences meaningfully. Most errors were errors of reference and location, typical in the writing of the deaf. Includes five references. (DB)
