Traditional education is centered on sources such as schools, teachers and print media. Students get information sources with registering with schools, teachers, and libraries. Before the digital age, information was not accessible to the majority of people, and even those who were accessed could not get the flow information with respect to today’s context. Modern society wants to know information as it happens and when happen, and the world moves from an information society to a knowledge society. Thus education is given the highest priority and brain power becomes the most valuable assets of an organization. The advancement of digital technology has been open many learning paths. Technology has made information accessible / transmitted from anywhere and by / to all groups people. Education has reached most parts of the world and ICT has become an integral part of human life. RADITIONAL EDUCATION
formal education is traditionally centered at the village level school while non-formal education is centered in the library in the form of newspapers and books. The teachers convey formal education using textbooks or notes prepared using their books and experiences. Students register and visit places that offer formal education. The library offers additional reading material to enhance their learning as well as reference facilities. A teacher must be educated and knowledgeable to be able to educate others. They must also gain skills in maintaining student attention and sending content in effective ways. So teaching is an important profession and people respect them for guiding and helping students to be useful citizen. With the advent of industry and commercial influence various forms of employment. When the population increases demand learning has also increased and thus traditional schools can’t handle the request. Thus new schools must be created and existing schools must be expanded, and New teachers are asked to deliver education. To meet the demand of inexperienced, under qualified and less trained personnel are used and thus the profession has changed from social services to commercial business. Business is regulated by remuneration and when lower people are able to tend to look for other higher job offers wage. Past governments used this sector as part of job creation thereby contributing to damage sector.
The Electronic and Digital Era
The electronic era began with the use of more than 100 wireless electronic communications years ago. Sending telegraph and radio messages is the most important application of this technology. His messages were passed through the air, unseen, on the wave radio. Since then the use of technology has moved from radio, to recording, to film, to television, to computers, to CDs, CD ROMs &
This technology is very useful for instant urgent messages and also for making people aware of local and international news. This has become informal but an effective education.
SUPPORT TECHNOLOGY AND APPLICATION
There are a number of technological components available to build knowledge management system . Local area network, Internet and Intranet is the backbone. They provide rapid transfer of transparent knowledge among people and applications. Internet applications built using software and tools enables collaborative intelligent access to knowledge. Appropriate access and Authentication layer ensures security aspects from such a system. Database and document act as a repository for generating knowledge. Explicit Organization Knowledge Organization and manage explicit knowledge including generation, creation or acquisition knowledge. Such activities can be carried out through tools like RDBMS and EDMS.
One of the most commonly used tools for managing information is a relational database management system (RDBMS). RDBMS have has been used by IT applications to manage operational data. The same technology now has been used for knowledge management. Traditionally managed RDBMS texts and Primitive data types such as numbers and dates. Knowledge must be represented using outside traditional data types such as characters strings and numbers. Thus another form of representations such as pictures and videos needed. Multimedia database have sink to manage that data. Education management operational data the system is managed using this technology. Student registration data, evaluation results and their appearance was recorded using student information system.
Electronic Document Management Systemn (EDMS) is a rapidly developing technology and considered a solution for organization that needs a way to manage information efficiently. EDMS application focus on electronic document control
Media for Explicit Knowledge
Explicit knowledge could be represented using different media. Text, graphics, animation,sound and video are the media to represent them. Unlike the traditional media in forms of books information stored digitally can be preserved without any forms of distortion and they can be accessed easily and quickly from any part of the world.
Text is one of the most effective components of representing knowledge. The words embodied as text, convey a powerful message and this has been widely used in handwritten and print media. Most data and information is represented through this medium. It is impossible to convey an unambiguous message without text. To convey a message effectively the message should be specific, definite, concrete and precise. Selection of suitable fonts and size is important for legibility and aesthetic effects. Learning is concerned, summarised text is used to identify the important points and detailed descriptions are for explanations and subsequent supplementary reading.
Text and graphics are the basic components of multimedia systems. Text without graphics will fail to retain person’s attention as well as long-term retention. Bitmaps (paint) graphics and vector (draw) graphics are two basic forms of still graphics. Each type has its own characteristics and satisfies different needs. Bitmaps stores the graphics as seen on screen while vector graphics stores the instructions of how the graphics is created. Colour is an important component of a picture. However when producing graphics colours should be chosen carefully to ensure effective and pleasing displays. Human eye react to light intensity and to the three colours red, green and blue. Like in the case of fonts and sizes of text, the choice of colour composition has immediate aesthetic impact.
Animation adds impact to a presentation. Unlike text and graphics these are dynamic time based media. The visual impact of animation is to harness the learning process. Animations usually take forms like moving an object across the screen, user-controlled movement of an object, bitmap flipping and full animation files. Authoring tools are used to create such objects.
All forms of verbal communication use sound. Technology has been used to transmit sound across the universe. Teacher’s voice has been the primary focus in delivering knowledge. Sound could be represented using computers, and MIDI (Musical Instrument Digital Interface) and digital audio are the two basic file types used in multimedia systems. A multimedia system requires the use of speech, music or special sound effects. When used for education, speech should be short, manageable and integrated with other media. It should be used as a complementary to text.
Video occupies the most disk space and bandwidth when used over the network. Hence video can be integrated with other media only through use of edited segmented video clips each conveying a specific message.
Accessing Explicit Knowledge
RDBMS and EDMS manage the explicit knowledge. They are accessed using various technologies such as Internet, Intranet, Search Engines and workflow tools .
Internet provides a cost effective global network backbone. It connects users from anywhere, as long as they have access to the web. This has allowed users to host information on their computers and make them available for others. Such computers need to be dedicated for that purpose as users will be searching for information at different times. These sites are called web sites and they are connected to the web on 7×24. This technology intends to provide unrestricted access to information. An educational institute will publish all information relevant to the public through their web sites. This technology has made information accessible as it happens and people access them at any time they want to do so.
Intranet is used only within an organisation, thus restrict access to information from outside the organisation. The appropriate security measures (e.g. firewalls) implements such requirements. These web sites allow employees and authorised users to access information while protecting the same from others. This technology is used to share confidential information within an organisation. Teachers and administrators could monitor the overall status of a student and hence take appropriate actions promptly.Teachers can also make their learning material and exercises available through them. Some elearning systems runs on these networks with login accounts created for its users. Search Engines are very effective powerful tools that allow text based information retrieval. Web based search engines deploy different types of navigation strategies. Meta searching, hierarchical searching, attribute searching and content searching are among them. This facility is now widely used by most users of the Internet.
