Introduction

The Idea:

Developing a virtual classroom system to promote a greater count of students to splurge into the field of Education. It integrates the benefits of a physical classroom with the convenience of a ‘no-physical-bar’ virtual learning environment, minus the commuting hazards and expenses. It will usher in the immense flexibility and sophistication in the existing learning platform structures, with the perfect blend of synchronous and asynchronous interaction. It provides a means of collaborative learning for the students.

There are basically 4 types of users:

Student Faculty College Management (Dean, HODs, Principal) Administrator

Purpose

VCS (Virtual Classroom System) aims to promote a greater count of students to splurge into the field of Education. It integrates the benefits of a physical classroom with the convenience of a ‘no-physical-bar’ virtual learning environment, minus the commuting hazards and expenses. It will usher in the immense flexibility and sophistication in the existing learning platform structures, with the perfect blend of synchronous and asynchronous interaction. It provides a means of collaborative learning for the students.

Highlighting the main features of VCS : Attend Lectures as per student's convenience. Appear for Exams, view Progress Reports and participate in extra curricular activities online. Faculties can evaluate test sheets, schedule tests and perform related activities online. Providing easy-to-access web based service which can give management an effective means of managing all resources..

Scope

Students can choose courses, attend lectures, take exams, view their attendance records, progress reports etc as per their convenience. Attend lectures either at the scheduled time or on request view lecture at a later time. Faculties can take lectures, upload assignments, announcements, evaluate answer sheets and also can upload lectures and other discussions in various formats as in videos, power point presentation etc. Upload and Download of various assignments, college notices, student's notices, journals, videos. Real Time collaboration among Users via Chat Rooms, shared and interactive Whiteboards.

Asynchronous communication in the form of Emails, discussion boards that enable communication to occur at "convenient-times" that suit student schedules and are not accessed at simultaneous or prearranged times. There can be Forums, Blogs etc to discuss various queries and to put up suggestions posted both by students and teachers. Administrator can generate reports, log files, backup/recovery of data at any time. Shared documents and media library that can help in active learning of a student. Images library. One-to-Many, Many-to-One and Many-to-Many information sharing. Availability of Voice Mail Box to allow faculties to get the descriptive messages left by the students. Provision of resources to arouse the interest of students in extracurricular activities like public speaking etc and to grasp the chance to enhance their personalities. Students can take up various quizzes which can help them to realize their inbuilt talents in various fields.

Special Featues

The special features included in VCS are as follows:

Entire navigation is AJAX driven, thereby making the application processing fast and easy for the

user.

Passwords are stored in encrypted format which enhances network security.

Image based authentication while registration ( Captcha) increases the security of application.

The application is SQL Injection proof.

Progress Reports of students are generated in a graphical format using JFREE API.

Tests(Examination) specific data is stored in database in XML format ( eg. Question paper,

Answer sheets, Syllabus etc.)

Their will be synchronous communication among students, faculties and management through

embedded Discussion Application.

Students, faculties, management and administrator can interact through embedded E-mail

Application.

Product Perspective

The web pages (XHTML/JSP) are present to provide the user interface on customer client side. Communication between customer and server is provided through HTTP/HTTPS protocols. The Client Software is to provide the user interface on system user client side and for this TCP/IP protocols are used. On the server side web server is for EJB and database server is for storing the information.

Manage Emails Manage Financial Transactions View Requests View Activity User Records View Crystal Reports Update/Delete Notices Update/Delete Files View Notices View Files Take backup of database Generate Reports

Scope of Extension

The Virtual Classroom System can be extended to be used by WAP enabled devices. This service can be extended to be accessible through GPRS so that the registered users can share and access information "on the move".

The Virtual Classroom System can be extended to include various extra curricular activities that will simulate in the overall development of a child.
