Hypermedia

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.

Hypermedia is a database format similar to hypertext in which text, sound, or display can be accessed directly from the display.

Examples

1. Links that view audio

2. Links that view images

3. Links that view videos

4. Hypertext links to other locations

5. (WWW) World Wide Web

CHARACTERISTICS OF HYPERMEDIA APPLICATION

1. Learner control

The learner makes his own decisions on the path, flow or events of instruction.


2. LEARNER WIDE RANGE OF NAVIGATION ROUTES

- For the most part, the learner controls the sequence and pace of his path depending on his ability and motivation.


3. VARIETY OF MEDIA

Hypermedia includes more than one media (text, graphics, audio, animation and video clip) but does not necessarily use all types of media in one presentation.

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.

advantages

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.

disadvantages

Uses in education 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.

That’s

All!!!

Thank you
