an extremely useful tool for sharing information on what goes on in universities and
classrooms and for establishing a new level of exchange with caregivers and the community.
It also provides the potential to deepen and expand the understanding on students across the
entire student curriculum (a learning effectiveness rationale). And it helps them to overcome
problems of distance and isolation (an efficiency rationale). Each of these there rationales
supports each other.
The Internet has penetrated rapidly and extensively into U.S. public universities. A U.S.
Department of Education survey found that as of fall 1996, 65 percent of universities had
HUT – Genetic Computer School Page5
Knowledge Base System System Guide
access to the Internet; penetration had increased by 15 percentage points in each of the prior 2
years. The Office of Technology Assessment (OTA) estimated that in 2000, U.S. universities
had 7.4 million computers for use in instruction. But in Viet Nam, instead of being fully
aware of that, we failed to apply it successfully. So what are the reasons? Inadequate facilities,
lack of human resource, limitation on development of technology and the deficiency of
infrastructure when referring to this problem. In fact, the impact on the bulk of teaching and
learning has been minimal. Developments in paper/printing technologies have had far more
influence, with the consequence that face-to-face discussion and paper resources still
dominate public education. As the matter of fact, there is a communication gap between
lectures and students only in classrooms because of the passive way of learning. In an attempt
to handle the knowledge, students have no choice except for the traditional means such as
coming to libraries to read printed materials.
Needless to say, the application of information technology is an access road to mine of
knowledge. Therefore, applying the information technology in the field of education becomes
more and more important and pressing. And it gives us the reason to hope that the quality of
education and training in Viet Nam will be so much improved.

1.2 BACKGROUND
What is a Web-based Knowledge Base System?
A web-based Knowledge Base System is an online Knowledge resource on the net.
Knowledge Base System creates a huge archive of information on a website that help people
gain knowledge. Knowledge Base System also is a communication tool that helps people
share knowledge quickly and easily.
Objectives of Web-based Knowledge Base System
Web-based Knowledge Base System changes significantly the roles of traditional lecturer and
student. Students assume increasing responsibility for their learning while lecturers become
resources, facilitators and evaluators, guiding students in their problem-solving efforts. For
you as a learner, the ability to concentrate and to use your time well is the key to succeed.
Since the dawn of the Internet age, the online Knowledge Base System was supposed to let
great lecturers reach any student, any subject, any time, and anywhere. Online
teaching/learning are not fixed in time or space. Many students find the flexibility of online
learning a practical alternative to sitting in a campus classroom for hours on end. Students can
interact with the lecturer and their classmates at any time from anywhere to seek clarification
for issues they encounter in their homework assignment, to discuss topics in the course
contents, or to initiate new discussions on related topics. A successful online discussion has
the same synergistic effect as group or in-class discussion, in which students build on one
another's perspectives to gain a deeper understanding of the materials form different
perspectives.
Online Knowledge Base System engages and empowers students, increase their enjoyment
and encourage them to share and participate in their learning process. In an effective

be provided.
The impact of class size is of concern to all parties involved on Web-based learning/teaching.
It takes 2 or 3 times as much time to teach an on-line course as a face-to-face course for both
students and the Lecturers. A subject that works for 15 or 20 students now may be possible
with 100 students.

Knowledge Base System System Guide
Online Knowledge Base System allows knowledge to spread near-instantly, and makes it
accessible to everyone, i.e., breaking down the walls of education. Given the ease and speed at
which information travels. Strategy using online Knowledge Base System could prove
successful not only economically, but could exploit also human resources that would foster
innovation and strengthen the democratic foundation of a knowledge-based society.
