Enhancing Accessibility in Mathematics and Science for All Learners

This work explores accessibility in mathematics and scientific fields, focusing on the challenges faced by individuals with impairments, including dyslexia and visual disabilities. It discusses the role of Learning Management Systems and the current disconnect between mainstream software and screen readers regarding mathematical content. Two approaches to improve accessibility are examined: a plugin for verbalizing MathML and an image-based method for automatically generating alternative text for mathematical formulas. Each method's strengths and weaknesses are analyzed, emphasizing the need for accessible tools for content creators.

  9. Thestateof theart “Currently there is a complete mismatch between mainstream software for mathematics and existing screen readers when it comes to multimodal presentations of formulae.  In most cases formulae are printed on the screen using graphical glyphs.  Hence, learning environments are basically unusable for mathematics by people with disabilities such as dyslexia, dysgraphia, and any visual impairment.” Mika Seppälä, Florida State University

  13. Theimageapproach • The formula isstored as animage. • Theimagecontains a standard tag “alternativetext” with a textual description. • In thisexample: “F open parentheses x close parentheses equal integral subscript a superscript b f open parentheses x close parentheses d x”
