CHAPTER 1 – SYSTEM SPECIFICATION1.1 SCENARIO AND QUESTION PAPER

1.1.1 Scenario

Information technology is becoming increasingly clear that the growth of computing andcommunications technology is exceeding our understanding of its economic and socialimpacts Information technology is being used by organizations in a wide variety of settingsand ways and that information technology is critical for the smooth operation of manyorganizations Further, its usage is positively correlated with organizational productivity andefficiency

Change driven by information technology is having a significant impact on every aspect oflife and is an increasingly critical issue for education Information technology is able toimprove the delivery of education and enhance student achievement They are not onlymake teaching, learning, study more convenient and easy but also ensure desired efficiencyand scientific methods Because of the following rationales that government attemptsencouraging the use of information technology in education The education system canprepare students to participate fully in an advanced information society in which they live (asocial rationale) Environments equipped with computers and network access are extremelyuseful for providing a foundation for learning, promoting independent learning, and creatingbetter environment To create universities that disclose information using the Internet (websites) is an extremely useful tool for sharing information on what goes on in universities andclassrooms and for establishing a new level of exchange with caregivers and thecommunity It also provides the potential to deepen and expand the understanding onstudents across the entire student curriculum (a learning effectiveness rationale) And ithelps them to overcome problems of distance and isolation (an efficiency rationale) Each ofthese there rationales supports each other

The Internet has penetrated rapidly and extensively into U.S public universities A U.S

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 ofbeing fully aware of that, we failed to apply it successfully So what are the reasons?Inadequate facilities, lack of qualified manpower, limitation on development of technologyand the deficiency of infrastructure when referring to this problem In fact, the impact onthe bulk of teaching and learning has been minimal Developments in paper/printingtechnologies have had far more influence, with the consequence that face-to-face discussionand paper resources still dominate public education As the matter of fact, there is acommunication gap between lectures and students only in classrooms because of the passiveway of learning In an attempt to handle the knowledge, students have no choice except forthe 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 ofknowledge Therefore, applying the information technology in the field of educationbecomes more and more important and pressing And it gives us the reason to hope that thequality 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 peoplegain knowledge Knowledge Base System also is a communication tool that helps people

Objectives of Web-based Knowledge Base System

Web-based Knowledge Base System changes significantly the roles of traditional lecturerand student Students assume increasing responsibility for their learning while lecturersbecome resources, facilitators and evaluators, guiding students in their problem-solvingefforts For you as a learner, the ability to concentrate and to use your time well is the key tosucceed

Since the dawn of the Internet age, the online Knowledge Base System was supposed to letgreat lecturers reach any student, any subject, any time, and anywhere Onlineteaching/learning are not fixed in time or space Many students find the flexibility of onlinelearning a practical alternative to sitting in a campus classroom for hours on end Studentscan interact with the lecturer and their classmates at any time from anywhere to seekclarification for issues they encounter in their homework assignment, to discuss topics in thecourse contents, or to initiate new discussions on related topics A successful onlinediscussion has the same synergistic effect as group or in-class discussion, in which studentsbuild on one another's perspectives to gain a deeper understanding of the materials formdifferent perspectives

Online Knowledge Base System engages and empowers students, increase their enjoymentand encourage them to share and participate in their learning process In an effectivecollaborative learning environment a group of students comes together to share and learnfrom one another You are held together by a common interest in a body of knowledge andare driven by desire and need to share problems, experiences, insights, templates, tools, andbest practices Active participation in collaborative learning deepens your knowledge byinteracting on a daily basis It is a channel for knowledge to flow and is a means tostrengthen the social fabric in online learning environment

Facilitating creative dialogues between lecturers and students is the Internet's greatestcontribution to enhancing education, much more important than just putting lecture notesonline Most face-to-face courses involve a low-level of collaboration among students andlecturers A Web-based environment is where the students can think and experience asequential flow of learning allowing "teach-yourself" by way of thinking for yourself

then learning, for the online learning the emphasis is on learning then teaching From theexperience in both settings, we have realized that for online Knowledge Base Systemstudents and lecturers are partners in the learning process Partnership makes the successfaster, less expensive, and easier to achieve There is great opportunity in putting thisconcept into the hands of lecturers and supporting their change in thinking with exposure toexcellent mentoring Therefore web-based system is for both students and lecturers as ateam without any separation

Students today no longer spend all their time in a noisy lecture room or the deadly silence inthe huge reading room of a university library These components of learning environmentstill exist but their functionality has changed Web-based system delivery is the beginning of

a new wave of technology development in higher education Freeing student work frompaper and making it organized and transportable opens enormous possibilities for re-thinking whole curricula: the evaluation of faculty, assessment of programs Besides therequired textbook a collection of online resources replacing the traditional printed materials

in the libraries must be provided

The impact of class size is of concern to all parties involved on Web-basedlearning/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 studentsnow may be possible with 100 students

Online Knowledge Base System allows knowledge to spread near-instantly, and makes itaccessible 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 provesuccessful not only economically, but could exploit also human resources that would fosterinnovation and strengthen the democratic foundation of a knowledge-based society

1.3 INFRASTRUCTURE

The faculty has an Information Center with more than 300 networked PCs that connectdirectly to the Internet A broadband will be implemented in a near future The faculty alsohas a server running MS Windows 2000 Server, IIS Web server and MS SQL Server 2000

2.2 PROGRAM DESCRIPTION

Overviews

The Knowledge Base System is created to run on Web, its objective is to deletecommunication gap between students and lecturers and support information exchangingeffectively Because the system uses Internet environment so it has several security modes

To access the system, user must input username and password or register new username andpassword If user provides wrong username and password, his/her accessing requirementwill be denied, vice versa, main page will be displayed You can use functions of the systembased on the permissions that assigned by administrators

If you are an administrator, you can access all functions of the system such as managingcontents, updating information users, adding and deleting users or categories etc

If you are a normal user that means you are a student, you can edit personal information,post articles, ask questions, browse contents, search information or require statistics

If you are a lecturer, you have all rights of a normal user In addition, you have moderator’spermissions, can give instructions, material, reply information for students or delete articleswith bad contents

How the program works

The Knowledge Base System includes five main functions: User Management, ContentManagement, Category Management, Search and Statistics These functions include severalsub-functions In general, all three objects (administrators, lecturers and students) joining inthe system can interact with these functions but in different levels In more details, let usconsider in turn how each of functions of the system interacts with user

First, in order to become a member of the system, user need register new username andpassword User Management will verify if this username exists or not, if it is a newusername, it will saved information of this user into the system’s database, on the contrary

students must provide his/her username and password If it is invalid user name andpassword, there is an announcement “this username does not exist or invalid password”.After becoming a member of the system you can use functions based on your role ContentManagement allows all users to post articles, rate articles, give comments, and requireinstructions and statistics But you only can edit contents of an article unless you have right

of an administrator, moderator or article’s author In addition, administrators andmoderators can delete articles if necessary

Category Management is reserved for administrator, they will determine user’s rights (read,write, edit and delete) for each of types of contents The system leans on this assignment tocontrol accessing level of users

Search functions allows user search information according to different criterions (search byauthor name, postdate, keywords, attachment and etc.)

The last function is Statistics; user can require the system return statistics such as number ofusers, number of articles and so on Users also can require other information statistics abouttop favorite articles, articles that have highest rate points or something like that
