Facilitating class discussion by having alternatives mirror source materials

Use case
Learners and instructors who use alternate versions not only need the same information as their peers, but also need to be able to communicate with others in the school environment regarding the materials. For example, instructors need to know which page to tell the class to go to. Students need to be able to draw their peers' attention to a particular element or to find an element that has been mentioned. This is true when the alternative is for a small portion of the media, as in a text alternative for an image, as well as when the alternative completely replaces the media, as in an e-book used to replace a printed textbook.
  • keep content divisions consistent, examples:
    • page numbers
    • chapters
    • sections
    • units
    • how audio files and transcripts are organized
  • keep semantics consistent, example:
    • a list should be either bulleted or numbered for all users (not one way for some and another way for others)
  • keep labels consistent, examples:
    • button text
    • heading text
  • think about classroom interactions when writing alt-text
    • for example, a class might discuss "the cartoon," so the fact that the image is a cartoon might be important to mention in the alt-text
TO COME: Optional, links to other entries in the corpus
Relevant W3C group(s)/specification(s)
TO COME: Where the target WG/spec is obvious, specify it
External relevant group(s)/specification(s)
TO COME: Where there are external groups/specifications that address on this problem in whole or part
Obviously, people can and will work around some of this type of issue through open communication. However, we want to design products/sites in such as way that we reduce as much as possible the amount of time spent on this type of clarification.
