How do students with disabilities access STEM content? What are some common barriers they may encounter when reading STEM content? Want to see how a screen reader actually works? In this workshop you will experience the user’s perspective through both shared user stories and a hands-on screen-reader demo, and learn how students interact with technology to assist their learning. Presentation by Zach Lattin, Campus IT Accessibility Coordinator and IT Assistive Technology and Web Accessibility Specialist at Clark College.
