Purpose: Braille is the primary medium of written communication for persons who are blind. Prior research shows that Braille literacy strongly correlates with stronger reading habits and the pursuit of higher education, whereas Braille illiteracy negatively impacts students' academic performance and ability to navigate the everyday world. A recent report found that there has been a dramatic decline in Braille literacy since the 1960s and that in the last two decades the literacy rate among blind children has persisted at just 10 percent. This project will develop a web-based tutoring system to provide on-demand Braille literacy support to the visually impaired. Project Activities: The main technological objectives include designing and implementing a user interface for dynamic Braille input and output, designing a rules-based expert system for the Braille curriculum, and designing a rules-based expert system to analyze student work and provide feedback. To assess implementation feasibility, the usability of the technology, and to gather data on the promise of the product to support student learning, a single-case pilot study will collect data from 50 students over 15 weeks. Outcome measures will include items from the Minnesota Braille Skills Inventory.
