Transcript of "Technologies of Online Learning (E-Learning)"

  1. 1. Chapter 5Technologies Of Online Learning (E-learning)
  2. 2. There are five main elements in a complete multimedia system.
  3. 3. STANDARD FILE FORMATSEach of the five elements mentioned has various standard file formats. file formatis a particular way to store information in a computer.The formats will allow you to make decisions of the type of text, graphic, audio,video and animation to use when developing your own multimedia program.
  4. 4. INTERNET BASED MULTIMEDIA
  5. 5. CD-BASED MULTIMEDIA
  6. 6. STREAMING MULTIMEDIAAn internet datatransfer methodthat facilitate thetransfer of audioand video filesfrom computer tocomputer in a“stream.”

  8. 8. Push Technologies and Data Channelso There are a lot of new technologies that try to address the link between existing media, with their synchronous broadcasting of news, weather, and sports, and the asynchronous nature of Web publishing.o Web content that is formatted for channel-based delivery is pushed directly to the end-users desktop.o Channels can be chosen, modified, or created from scratch.
  9. 9. Audio Chat and Voice over Internet Protocolo Point-to-point audio connections can be made between almost any two computers on the Internet,o Some Internet service providers (ISPs) and online services are offering free Internet-based long-distance service that connects individuals calling through a personal computer to the public telephone system.o Teacher and student communication can be enhanced by the opportunity to speak to one another to discuss an assignment without the expense of long-distance tolls.
  10. 10. Web Whiteboarding o Web whiteboarding is a form of graphic conferencing used in combination with VoIP that support real-time collaboration. o Whiteboarding emulates writing or drawing on a blackboard. o With a whiteboard, both teachers and learners can create, manipulate, review, and update graphical information online in real time while participating in a lecture or discussion. o Users can annotate by writing; cutting and pasting; or clicking, dragging, and dropping. o Contents can be saved and used in future presentations.
  11. 11. Web Whiteboarding
  12. 12. Instant Messaging o It allows short messages to be sent electronically from computer to computer. o As in e-mail, the messages are stored on a central server until the recipient collects them. o ICQ is only one of a growing number of instant messenger services that have appeared online in the last three years. Other than ICQ, users can choose from MSN Messenger (from Microsoft), AIM (AOL Instant Messenger), and other similar applications. o Instant messaging is not yet used as an efficient content-delivery teaching tool.
  13. 13. Hand-held and Wireless Technologieso Mobile computing are being chosen over desktop and even laptop computers, not only as the preferred Internet access tool, but also for common computing applications, such as word processing and spreadsheets.o These devices are telephones, tablets, e-books, and Web pads, and are now including a Web browser, an instant messenger, and an e-mailer, along with other features.
  14. 14. Peer-to-Peer File Sharingo Peer-to-peer applications allow users to share any kind of file with a limitless population of other Internet users.o Of all the P2P(peer-to-peer) applications, Napster has become the most well-known, because of its focus on facilitating the distribution and sharing of files, and especially copyright-protected media, mainly music files encoded in the MP3 format.o Research and other materials could easily be offered online and offering the student or teacher a wealth of knowledge that might not otherwise be available.
  15. 15. Learning Objectso Learning objects are more highly developed, consisting of discrete lessons, learning module, or courses.o Learning objects are discrete items that can be integrated into lessons; for example, a text, graphic, audio, video, or interactive file.o They could then be made available in online databases in the form of animations, videos, simulations, educational games, and multimedia texts.
