Features of Hypertext Useful for Teaching

  1. a home page that can be reached easily from the other pages. This helps the reader to get back on track when lost in the nooks and crannies of the presentation.
  2. study guides that package WWW presentations into logical sequences and group materials for each assignment. Each guide is a specialized home page.
  3. each citation as a "hot word", and clicking takes the reader to exactly that reference in the list.
  4. layered presentations of equations. You click to select a cursory derivation, a detailed derivation, or a ridiculously oversimplified treatment for anyone with weak math.
  5. each assay procedure with an index page with entries for the techniques themselves, evaluations and tips lifted from Ph.D. or M.S. theses, lists of equipment, and name of vendors.
  6. a glossary. Key words on various pages are "hot" and take the reader to exactly that entry in the glossary.

Links to other pages can maintain the logical thread or can branch. For example, an introductory page links to more advanced material, and more advanced pages have "hot words" that bring up pages with explanations. The glossary and the literature citations have no links because the reader will return using the "BACK" feature of the browser software. This is much more sensible than scrolling through a long list to find links because you almost always want to go back to where you were.
