By: Attika yuli Indriyani

IntroductionThis chapter includes features used in online instruction today, and those we may use tomorrow. Education is one of the fastest growing and social sectors in the world, and the use of new technologies is an integral and driving component of that growth.

Multimedia on the InternetMultimedia have been using on the Internet to help deliver sources and materials in education field. Internet speeds limit quality and quantity in transmitting larger sound, animation and video files. However, with streaming multimedia, now larger files can be delivered even over modem connection. Streamed media packets can be played as soon as the data starts arriving at the receiving computer, user do not have to wait until the full file has been downloaded.

Multimedia on the Internet Streaming Audio Audio was the first type of multimedia to be delivered over the internet in a streaming format , and concert and ‘live’ radio broadcast. A wide range of streaming audio formats is in use on the web today, but while each is different in name, the basic technology reamins the same.

Educational Uses: prerecorded lectures, interviews with guests, student projects, samples of student classroom interaction, etc.

Multimedia on the Internet Streaming Video As provider, we have to know that there are some difficulties that we will face in the future while producing video. We have to consider about the size, place to save the recording video sometimes it required some hardware and some additional software.

Educational Uses: Video clip use in online education that can be used for additional resources on educational web page or classroom courses or online courses delivered synchronously.

Multimedia on the Internet Push Technologies and Data Channels

Channels of ’pushed content’ are another source of dynamic and often media-rich content online. Channels can be choosen, modified, or created from stratch. They are used for monitoring new content from relevant sites, as well as for navigating sites that the channel holder considers interesting. An individual user can create channel that links to number of sites that pertain to a specific subject of interest.

Educational Uses: can be used to feed inexpensive and timely news, weather, and sports or other information from relevant sites to a class room for use in reports, essays or current event classes. School could create channels available for subscription for the parents and other interested parties, school will update and offer suplementary information for them.

Multimedia on the Internet Audio Chat and Voice over Internet Protocol Point-to-point audio connections can be made between almost two computers on the internet and some Internet Service Providers(ISPs) and online services are now offering free Internet-based long-distance service that connects individuals calling through a personal computer to the public telephone system.

Educational Uses: Internet telephony, electronic blackboard or known as audio-graphic teleconferencing.

Multimedia on the Internet Web Whiteboarding Whiteboarding emulates writing or drawing on blackboard. With a whiteboard, both teachers and learners can create, manipulate, review and update graphical information online in real time while participating in lecture or discussion.

Educational Uses: the blackboard subtitute allows for emulation of classroom lesson. Student in different locations can participate actively and collaboratively with the teacher and other students in the creation and adaptation of graphical information.

Multimedia on the Internet Instant Messaging It has similarities to other modes of text-based communication, such as e-mail or Internet Relay Chat(IRC). It allows short messages to be sent electronically from computer to computer. It more dynamic that is shows all of the group members when the recipient logs on.

Educational Uses: Instant messaging is not yet as an efficient content-delivery teaching tool. Its strength lies in its ablility to facilitate immediate contact with other students and teachers, or it with a tutor who is supervising chat sessions.

Multimedia on the Internet Hand-held and wireless Technologies Mobile computing has arrived. Wireless devices are being chosen over desktop and even laptop computers, not only as the preffered Internet access tool, but also for common computing applications.

So your next computer probably will not just be a computer. It will also be a phone and organizer, where you will use it to check your bank balance, buy groceries, and bet on the lottery. With the advent of infrared networking, these hand-held computer devices can offer students and teachers a previously unknown degree of flexibility.

Multimedia on the Internet Hand-held and wireless Technologies

Educational Benefits and uses: as affordable access to high bandwith increases, and as the cost of wireless devices that will be able to incorporate all the features of a PC decreases, the educational possibilities become unlimited. It might mean the end of paper-based teaching and learning, lost homework, missing tests, and costly textbooks.

Multimedia on the Internet Peer-to-peer File Sharing

Allows users, regardless of location or connection speed, to share practically any kind of file with a limitless population of other Internet users.Educational Uses: Easy to make connections between learning objects, intelligent eductional systems, and the peer-to-peer model. Upcoming peer-to-peer educational applications include edutella and eduSplash, product that support the exchange of learning objects or units of learning.

Multimedia on the Internet Learning Objects Audio was the firt type of multimedia to be delivered over the internet.

Educational Benefits and uses: the principle of learning objects comes from their usability. As discrete units, they can be incorporated into a wide range of courses of learning scenarios. Their standards-based structure makes them available for use in many different learning management systems and other applications.
