Learning Outcomes for this Session
1. Consider how properly structured math supports inclusive teaching and learning.
2. Apply an understanding of access technology and web accessibility to the challenge of online math.
3. Reflect on the way collaboration can ensure workflows produce properly structured math.
4. Gain familiarity with tools and techniques.

Important Message
• Workflows MUST ensure math is structured• Content prepared ahead of time should be fully accessible• Activities should be designed to work for AT users• Design should support equitable use
• More than one way to get it done • Consider institutional culture – faculty production/adoption• Consider student preferences - need for mobile access

Math Accessibility - Workflows
• If interactive websites are not accessible from the outset, it is very difficult to “fix” with accommodation
• It is hard to ensure equivalent ease of use in a timely manner when the content is stored beyond a firewall

Math Accessibility - Workflows
Addressing accessibility proactively requires that we:
• Know when/where accessible versions exist
• Increase adoption of those accessible options
• Work interactively and collaboratively with content publishers

Math Accessibility for All
• Users need flexibility and robustness when interacting with math • zoom/re-size or change color or contrast• keyboard navigation of content at preferred level of detail
• Users need flexibility and robustness when creating math • independent authoring• checking work in progress• working collaboratively with others
• Users rely on Institutions to ensure materials and activities are usable• Professional Development & Technical Support = Ethical Responsibility

Summary - Math Accessibility Challenges• Math is represented spatially - often treated as image which is hard to OCR• Alt text as means of providing access is limited – static rendering

Summary - Math Accessibility Challenges
• Math content (even when properly structured) is not always accessible via assistive technology
• Math content is found in (much) more than just math courses• Providing inclusive math is especially important because math is a
pre-requisite for many other areas• People may have strong emotional associations with math• Math can be a “brick wall” if there are teaching/learning mismatches

Summary - Math Accessibility Opportunities
• Math is beautiful and full of natural connection points that are grounded in reality and leverage all the senses
• Technology can create structure that is perceivable in many ways, supporting individual learner preferences
• Collaboration can bring divergent perspectives together to address complex challenges in unique and creative ways
