Otherwise, the extra media are simply teasers. The quizzes extend the possible uses of the software into the domain of programmed instruction. The students derive extra educational benefits from response oriented assignments over and above more passive activities like viewing, listening or reading. A 'digital textbook' combining text with audio and video is worthy of exploration at least by historians whostudy the twentieth century. The quizzing feature could be a helpful study aid for any period.
Course packs are a standard of education today.
On-line delivery of course pack information is a compelling alternative to many professors. One of the easiest ways to place course materials on-line is to use document imaging software like Adobe Acrobat. Creating a document with Acrobat can be as easy as printing, and Acrobat preserves page formats. However, Acrobat simply makes a graphic image of the page. In order to make the text searchable or to insert links more work is required.
