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 chil...

In the early 2000s, international comparative studies reported declining levels of numeracy skills among adults (16- to 65-year-olds) in the United States. In this project, the researchers aimed to further develop  an on-demand automated tutor that focused on developmental mathematics for adult learners and underprepared college students requiring remediation.

This project team developed a prototype of a web-based software that used artificial intelligence techniques to provide support for adult learners and remedial college students as they studied basic math.

Compared to students in other industrialized countries, U.S. students perform poorly in studies of achievement in high school chemistry, a core subject in the physical sciences course sequence in U.S. high schools. The purpose of this project is to complete the development of a computer-based tutoring and assessment system for a first-year chemistry course, and to obtain evidence of the system's potential to improve student learning and achievement in chemistry.

In this project, researchers iteratively a prototype of artificial intelligence (AI) tutor software program developed and tested artificial intelligence software for individualized math tutoring for students who are blind or visually impaired.  The software aimed to provide full accessibility to the blind and individuals with reading disabilities, using Internet screen reader technology.
