The document discusses problems faced by visually impaired students in accessing textbooks, including that Braille texts take a long time to produce and many cannot read Braille, enlarged texts are heavy and inconvenient, audio texts have playback issues, and images are inaccessible. It proposes using eTexts with MathML to describe math expressions in a way that is readable by screen readers, benefiting not just visually impaired students but also those with other disabilities. Surveys find 90% of math instruction relies on textbooks, so accessible eTexts could help more students succeed in math.
