Hypermedia is a computer-based information retrieval system that enables a user to gain or provide access to texts, audio, and video recordings, photographs, and computer graphics related to a particular subject.
Hypermedia is anything that allows the user to gather information in a nonlinear way. This means that the user has a choice as to what path he or she takes in order to gather information. The user has the option of skipping certain items or can go through every piece of information that is listed
It is a term created by Ted Nelson in 1965
Examples 1.Links that view audio 2.Links that view images 3.Links that view videos 4.Hypertext links to other locations
The World Wide Web (WWW) is the best example of hypermedia applications Through WWW it is possible to deliver hypertext, graphics, animation and sound between different computer environments .
HTML formatting that is interpreted by the client's browser.
Hypertext links to other locations within a document or to other documents.
One of the major advantages of hypermedia is the ability to quickly follow associations and look up related material.
References can be traced both back-wards and forward in a way which can be difficult and time consuming with printed media. In addition, the user can annotate the material and create new references.
Information can also be structured in a variety of ways. Multiple organizations of the same material allow for specialized structures for different user categories. (Conklin 1986, 1987).
The student can browse the material and find new information as she explores a subject area.
hypermedia systems is usually considered as fun to use.
Ease of browsing might increase the risk that the learner skips through the material much to hasty, and thus get a shallow and fragmented conception of the subject.
The risk of getting disoriented can result in confusion rather than understanding, especially if the user jumps around between different nodes in a more or less random manner.
Using a hypermedia system involves a certain cognitive overhead . The problems is that the user has to interact with the system in order to accomplish anything, which can be more or less complex.
Hypermedia systems are used in educational environment. The active participation of students is one of the major advantages of hypermedia systems.
Hypermedia enables students to explore and construct their own learning.
This method of learning breaks down the barriers of time and place, allowing maximum flexibility for the learner. Students are provided a means to learn individually and at their own speed. Students can repeat difficult concepts, or skip already mastered skill areas.
Uses in education
Also it is used for effective education. Hypermedia can help students achieve a wide variety of goals in education for example:
