CALL:hypertext and hypermedia

hypertext?hypermedia?err..frankly speaking, i don't know what those two words mean before Canne and Kath's presentation. i never knew that all those linking and jumping from one webpage to another are very closely related to hypertext and hypermedia. so now i know.

hypertext:non-sequential text which is organised to allow readers/users access to nonlinear information.

hypermedia:superset of hypertext.electronic documents that can access and link together a rich collection of resources in various media (not just text).

so i found out there are several benefits of hypertext and hypermedia in learning, particularly on reading skill:

1.Hypermedia enables user to locate and view every word in an online dictionary.

2.Hypermedia's linkage can be used to support reading in a foreign language.

3.Hypertext allows the user to take charge of the learning pace, level of assistance, and the order in which the data is accessed.

4. Hypermedia documents contain links not only to other pieces of text, but also to other forms of media - sounds, images, and movies.
