Abstract
Virtual classroom is a computer medicated communication system. The need of gathering at one place for communication in traditional classroom is been overcome by virtual classroom, the main advantages of virtual classroom is that due to shrinking distance communication is improved.
Under virtual classroom-concept come the tools it should provide to the learner, students prerequisites for virtual classroom and types of virtual classroom.
The architecture of virtual classroom is in three phase which include the normal instructor to classroom setup, classroom behind firewall setup and instructor to group of geographically dispersed student.
There are various developed virtual classroom one of which is blackboards, which include synchronous as well as asynchronous environment of teaching. Its possible features are explained in brief.
Introduction
1.1 WHAT IS A CLASSROOM:
A classroom can be defined as a communication system that makes it possible for a group of people/users to come together to dialogue about something they want to learn, and to look at visuals (pictures, diagrams) and text that might aid them in understanding.
The conventional classroom is surrounded by walls that provide protection from outside noise and interference, contributing to a more effective learning process
1.2 Need Of Virtual Classroom:
Traditionally, teaching by distance or externally has involved the provision of written notes, which were sometimes supplemented by audio-visual materials such as video and audiocassette. This approach has been surpassed with the integration of written notes, interactive multimedia and the World Wide Web. Interactive multimedia may have been presented on CD-ROMs or servers. These interactive programs have included items such as digitized textbooks, video, animation, photos and figures, as well as self-test facilities. A major benefit of the Virtual Learning Center is the reduction in travel time and expense compared to traditional classroom training
The virtual classroom can be simply viewed as a forum or meeting area for students and the lecturer. Just as the lecture theatre, tutorial room or laboratory provide a physical ‘place’ for students to meet and learn, it also provides a congregation point through which knowledge and experiences are shared, debated and compared. The virtual classroom presents an opportunity for those students who are unable to physically meet at a campus to gather using an alternative environment.
VIRTUAL CLASSROOM OVERVIEW
The VIRTUAL CLASSROOM is not much different from a REAL CLASSROOM . It is simply an interaction defined by instructors and users in hyperspace or that area of communication held within the confines of the computer.
2 Expectation for Learning
Web courses must strive to create within learners and educators the same expectation that learning will occur and that the class is serious business. Learners will have to complete the coursework and meet their responsibilities with the same intensity that they would in classroom. Instructors will have to treat the course with even more preparation that they invest in the regular classroom because the pedagogy is very different for the webcourse.
4 Experimentation and Application
Theory is important for the mastery of any subject but experimentation and application of knowledge in applied, practical contexts is equally important. In a real classroom, learners participate in lab experiments or classroom discussion. In the virtual course, students must also participate in assigned experiments and in active discussion groups. The web site will have assigned reading and online discussions and emphasize student completion of assigned hands-on laboratory projects that range from library assignments to knapping of stone and use of high power magnification of use-wear. The online presentations will introduce the learner to a broad range of theories and methods, will assign experiments, and require discussion, written summaries, and database building. The introduction is online, the hands-on exercises are real, and the summary and presentation is back on line. The learners will be required to develop skills and knowledge appropriate to the course.
2.1.6 Secure Learning Environment
An effective classroom, virtual or real, is one in which learners feel free to express themselves in appropriate ways, take risks to learn more, share their ideas openly, and ask questions. Learners should have the opportunity to question instructors and other learners, and to test their ideas and skills in non-threatening ways. Safe web sites establish protocols for using the technology (equal access to resources, ensuring that non one can tamper with another learner's or the instructors' materials) and for communicating with each other ("non flame" rules for e-mail messages, guidelines for netiquette, and procedures for taking turns in chartrooms).
2 Traditional Classroom and the Virtual Classroom.
A really good teacher can make the traditional classroom an exciting place, and the same is true for the online classroom. The specific goals of any class, or course, must be clear in the mind of the teacher, as well as the best methods for the type of classroom, and type of content presented.
Traditional education and online education each have unique advantages. The emotively supportive face-to-face environment of the classroom allows immediate feedback, and an immediate social environment, which has been viewed as essential to a quality educational experience. Facial expressions and body language are vital clues to the level of student understanding and engagement, and fundamental to recognizing those "teachable moments!".
Asynchronous:
In an asynchronous environment, the "sender" and "receiver" do not have to be in the same place at the same time. For e.g. Books operate asynchronously the author writes the text that is read by the reader at a later date and time. Email, discussion boards, file exchange areas, and web pages are all forms of asynchronous computer-mediated communication. The Virtual Classroom participants may dial in at any time around the clock, and from any location in the world accessible by a reliable telephone system. The fact that the educational process is asynchronous means each student may engage in more reflective thinking before having to answer or discuss issues. The internet facility with high communication channel can help the student to learn to any depth as desired.
Synchronous:
In synchronous environment communication occurs at the same time or "live." Face-to-face classrooms are an example synchronous communication. In a computer-based environment, synchronous communication includes text based Internet chat, instant messaging (through programs like AOL Instant Messenger or ICQ), whiteboard applications (which allow users at a distance to draw on or edit images online), and Internet audio and video conferencing. students get instructions at a time synchronously via instructor. It is a preplanned meeting announced by instructor. So one can discuss to other student or instructor using chatting Internet facility
Advantage of Virtual Classroom
In distance education self-instructional material has to play the role of motivating the students, creating and maintaining interest in the topic. It is an accepted fact that individuals are capable of self-learning only if they are provided with cleverly and sensitively designed materials of relative subject domain. Hence to increase the self-learning capability and interest, the concept of virtual classroom is developed and backbone for any distance learning.
Advantages of Virtual Classroom are listed below:
Virtual classroom concept in Distance learning engineering education, have to be so developed, that they are able to face the challenge of Learning, that is learning can be done at any time and in any place. The constraints of time have to be removed, removing the time-driven element from their functioning.
The students in the virtual classroom can have facilities of E-library, E-laboratory, conference facility to discuss the subject with other students or experts. Collaborative technologies such as messaging, document conferencing, multipoint audio- and videoconferencing, helps to create an interactive learning environment between students and Instructor.
Animations, video clips, lecture notes and pre-planed meeting helps students to learn effectively.
The availability of online courses at anytime, from any location, supports the current boom in home-based learning. Home-based Internet access supports ongoing opportunities for lifelong learning, group dialogue, and participation in communities of interest.
In recent years, corporations and educational institutions have been increasingly faced with the challenge to provide a learning experience for students who are geographically dispersed students who are spread across a province, state, country or even a couple of continents. Until recently, the only reasonable ways to conquer distance were either to move the students to the instructors, or to move the instructors to the students. In either case, students and teacher are being brought together physically in one place. The obvious way around all this moving of people is to find a way to provide a learning experience at a distance. The goal would be to use the best instructors to reach more students with constantly high-quality education, no matter where the instructors or students are located. This facility is provided by virtual classroom where both the instructor and student need not be at same place.
6. Conclusion
In the recent computerized society, learners no longer have to participate in the conventional school-based lecture hall. To develop such an environment, we have summarized our design concepts.
In the traditional classroom, some students process the presented information immediately and respond with interesting and valuable comments; other students might have interesting comments but not right away. Asynchronous conversation allows every single student to participate in the class discussion without being forced to an immediate response, without being interrupted by another student .
Virtual classroom system will increase course access for students, increase quality of the educational experience, and lower educational costs. The key issue is to exploit the ability of the technologies to provide a more flexible learning environment.
For distance students, the prospect of communicating synchronously using audio and videoconferencing over the Internet provides one of the most exciting aspects of learning in the third millennium.
Need for the virtual classroom of tomorrow - that is, one which offers real-time verbal communication, as well as asynchronous written interaction will need to be considered in addition to the excitement of technological advances. The use of communication as an enhancement of educational process will remain the same what will change is mode and method of communication.
