MULTIMEDIA A generic term for multimedia refers to the sequential or simultaneous use of a variety of media formats in a given presentation or self-study program.

MULTIMEDIA The term multimedia goes back to the 1950s and describes early attempts to combine various still and motion media. Today examples of multimedia includes slides with synchronized audio tapes, video tapes, CD-ROMS, DVD, the World Wide Web, and virtual reality.

MULTIMEDIA The goal of multimedia in education is to immerse the learner in a multisensory experience to promote learning. Multimedia addresses different learning styles. These are auditory, visual, and tactile learners

DIFFERENT TYPES OF MULTIMEDIA Multimedia kits Hypermedia Interactive media Virtual reality Expert systems

MULTIMEDIA KITS A collection of teaching/learning materials involving more that one type of medium and organized around a single topic. This kits could include CD-ROMs, filmstrips, slides, audiotapes, still pictures, transparencies, charts, real objects, etc.

ADVANTAGES Interest. Multimedia kits arouse interest because they are multisensory. Cooperation. Kits can be an idea mechanism for stimulating small-group project work. Logistics. Kits have an advantage of being packaged to be transported to locations

LIMITATIONS More expensive than conventional methods Time consuming to produce and maintain the materials Replacement of lost components make the kit frustrating to use

HYPERMEDIA Hypermedia refers to computer software that uses elements of text, graphics, video and audio connected that users can move within the information. Based on cognitive theories of how people structure knowledge and how they learn

HYPERMEDIA CONT. Designed to resemble the way people organize information with concepts and their relationships, or links, are associations between ideas. No continuous flow of text, as in textbook Information is broken into small units

ADVANTAGES Engrossing-capture and hold interest Multisensory-incorporation of sounds and images Connections-connect different ideas from different media sources Individualized-allows users to navigate through information according to interest

LIMITATIONS Easy to get lost-users could get confused Lack of structure-some students may become frustrated Complex-advanced programs may be difficult to use Time consuming-more time needed to reach objectives

INTERACTIVE MEDIA Computer based interactive media creates a multimedia learning environment that capitalizes on both video and computer-assisted instruction Instructional delivery system in which recorded visuals, sound, and video materials are presented Viewers can make active responses, with those responses affecting the pace and sequence of the presentation

ADVANTAGES Multiple media. Text, audio, graphics, still pictures, and video can be combined in one easy to use system Learner participation. Maintain attention, and allows greater participation than video alone Simulations. Can be used to provide simulation experiences

LIMITATIONS Cost. The most significant limitation to interactive video is the cost. Production expense. Expensive to produce CD- ROM and DVD discs, making it necessary to rely on commercially prepared material Rigidity. Discs cannot be changed once they have been made and may become outdated

VIRTUAL REALITY One of the newest multimedia applications of computer-generated technologies A computer-generated three-dimensional environment Places the user into the virtual environment and provides an opportunity to interact with that environment

ADVANTGAGES Safety. Creates a realistic world without subjecting viewers to actual imagined danger or hazards Expansive. Provides students opportunities to explore places not feasible in the real world

LIMITATIONS Cost. The equipment is extremely expensive Complexity. The technology is complex and does not lend itself to most classroom uses Limited titles. Limited software “realities” available at this time

EXPERT SYSTEMS After computers became a reality, scientists were intrigued by parallels between human brain and computers Expert systems is a software package allowing collective wisdom to bear on problem Games were developed One such program is a program that help train doctors make accurate diagnoses of diseases The term knowledge engineers has been coined for people who work in this field
