The Story: How ODL efforts to assist faculty with ADA 508 compliance in their online courses led to development of “manymedia” and a captioning system for online materials. Motto: Always an Opportunity to Learn

By deconstructing and captioning the Tegrity presentationswe created a large and diverse set of learning media for the student that can be used in a variety of ways. The Faculty only create one presentation.

Leyla Zhuhadar –Doctoral student in Computer Science at The University of Louisville and an Instructional Designer for the Office of Distance learning at WKU. She will talk about the captioning system we built and how students use the “manymedia”.
