| 總結: | Presently, advances in Internet technology and the human-computer
interface have created a wealth of new opportunities for the development of webbased
interactive distance learning systems. However, most of the effort of
developing the system focused on the information receiver and less on helping the
information provider in delivering the information.
This thesis describes WebEd, a user-friendly system that facilitates the
information provider or the instructor to carry out web-based courses. The WebEd
approach is to make the instructor centrally involved and maintain the ownership of
their courses. It also enables the students to access the course and interact with the
instructor with the aid of the system provided services. The system supports various
services for system management, communications, file management, and content
management and retrieval. Some of the examples of services provided by the system
are Appointment Manager, Announcement Board, Content Manager, etc. WebEd distance learning system is dynamic and interactive, being
developed using Java and CGI script. A JavaCGI proxy has been developed to
handle the dynamically generated pages and services.
The system is built on a 3-tier architecture which splits the system
processing load between the client-side workstation that runs on a browser, web
server that sends HTTP commands over a network and WebEd services that handle
the web-based distance learning activities. No installations are required in order to
access the system as the courses are accessible via a browser.
An evaluation on the system has been conducted in getting users feedback.
Analyses based on the system evaluation have been carried out to identify
weaknesses of the system. Finally, the system limitations and proposed solutions are
suggested for future enhancement of the system. |
