  2. 2. DEFINITION OF MULTIMEDIA From the words „multi‟ and „media/medium‟ Multi – refers to many or multiple Media/medium – is a tool, vehicle or agent to present or convey something Multimedia is all about communicating in several ways
  3. 3. Multimedia DefinedMultimedia means two or more media:sound, images, text, animation, and video.When the term is used with computer technology, multimedia refersto a variety of applications that combine media and that use CD-ROM, video, audio, DVD, and other media equipment.
  4. 4. Introduction The world in which we live is changing rapidly the field of education is experiencing these changes in particular as it applies to Media Services. The growth in use of multimedia within the education sector has accelerated in recent years.
  5. 5.  Teachers primarily require access to learning resources. which can support concept development by learners in a variety of ways to meet individual learning needs. The development of multimedia technologies for learning offers new ways in which learning can take place in schools and the home.
  7. 7. Text text has the most impact on the quality of the multimedia interaction. acts as the keystone tying all of the other media elements together. It is well written text that makes a multimedia communication wonderful.
  8. 8. Sound enables teachers to present lots of information at once. Sound used creatively, becomes a stimulus to the imagination; For instance, a script, some still images and a sound track, allow students to utilize their own power of imagination without being biased
  9. 9. A great advantage is that the sound file can be stopped and started very easily.
  10. 10. Video The representation of information by using the visualization capabilities of video can be immediate and powerful. Video can be used to give examples of phenomena or issues referred to in the text For example, while students are reading notes about a particular issue,
  11. 11. a video showing a short clip of the author/teacher emphasizing the key points can be inserted at a key moment dramatic ability to elicit an emotional response from an individual. can provide a strong motivational incentive to choose and persist in a task.
  12. 12. Animation used to show changes in state over time to present information slowly to students primarily used to demonstrate an idea or illustrate a concept. Video is usually taken from life, whereas animations are based on drawings.
  13. 13. Graphics provide the most creative possibilities for a learning session. can be photographs, drawings, graphs from a spreadsheet, pictures from CD- ROM something pulled from the Internet the capacity of recognition memory for pictures is almost limitless
  14. 14. MULTIMEDIA HARDWARE ANDSOFTWARE HARDWARE  SOFTWARE  Input devices  Text  Output devices  Graphic  Audio  Video  Animation
  15. 15. Educational Requirements Employing multimedia tools into the learning environment is a rewarding but complex and challenging task. All of the multimedia formats available: text, sound, video, animation and graphics, already exist in one form or another in most libraries. Students can explore an almost infinite variety of information.
  16. 16.  Giving students an opportunity to produce multimedia documents of their own provides several educational advantages.  Students work with the same information from four perspectives:1. as researcher, they must locate and select the information needed to understand the chosen topic;2. as authors, they must consider their intended audience and decide what amount of information is needed to give their readers an understanding of the topic;
  17. 17. 3. as designers, they must select theappropriate media to share the conceptsselected4. as writers, they must find a way to fit theinformation to the container including themanner of linking the information for othersto retrieve.
  18. 18.  When defining the appropriate medium to use it is vital to „know‟ the audience and the technical specification of users‟ machines. It is important to bear in mind the nature of the audience, especially their age group and culture mix.
  19. 19. Human – Computer Interface Multimediaapplications like any other application, appliance or tool, benefit from being easy to use,
  20. 20. Classroom Architecture andResources  The technology needed to support classroom teaching has increased in complexity.  only a few years ago all that a lecture room needed were some seats for the students, and a blackboard and a lectern or table for the teacher.  . Now there is the computer, networks and related display tools.
  21. 21.  From having a next to zero maintenance cost, the teaching room is becoming not only costly to equip, but costly to run and maintain, including the escalating costs of security.
  22. 22.  The live lecture in the digital theater is concurrently broadcast to the remote distance-learning site. Multimedia offers the lecturer many benefits satisfying educational objectives, increasing students understanding, demonstrating events, showing places, conducting experiments which would otherwise be impossible.
  23. 23.  Many school reform models focus on a significant restructuring of the classroom. multimedia brings a new dimension to reading and writing, develop basic skills in information retrieval in multimedia environments.
  24. 24. Concerns The fusion of all types of media in a digital world captures the ethos of the new technological age Multimedia: a combination of video, text, still images and sound can provide an effective learning aid. “Putting computers into schools will directly improve learning,”
