Math accessibility is one of the biggest challenges faced by teachers of students with visual difficulties or impairments. In February, Steve Noble's blog post (MeTRC Research Underscores Need for Accessible Math) talked about a study involving students with reading-related learning disabilities. The study found that these students have 2-3 times as much difficulty reading math than they do reading plain text. When given accessible math materials, their outcomes on tests were much better than those students who didn't have access to accessible materials.
Adding additional credibility to their findings, these results have now been published in Information Technology and Disabilities Journal a peer-reviewed journal.
With positive outcomes like this, you may want to know what you can do to help your students. Please see "What can you do to help promote math accessibility?" for some suggestions on what you can do to get accessible books into your classroom
