There has been growing interest in designing online learning systems that are accessible to learners with special needs. In this project, an existing online math word problem solving system was modified for use by blind students. Text-to-speech technology was used to present math word problems in audio format, and to provide audio feedback to students about their answers. The adapted system was evaluated with blind middle school students (N = 11). Results indicated that blind students’ problem solving was comparable to that of sighted students who had worked with the original system.
