It lets people be creative. It lets people be productive. It lets people learn things they didn't think they could learn before, and so in a sense it is all about potential.” S TEVE B ALLMER -CEO Microsoft Virtual classroom is a learning environment created in the virtual space. The objectives of a virtual classroom are to improve access to advanced educational experiences by allowing students and instructors to participate in remote learning communities using personal computers; and to improve the quality and effectiveness of education by using the computer to support a collaborative learning process. The explosion of the knowledge age has changed the context of what is learnt and how it is learnt – the concept of virtual classrooms is a manifestation of this knowledge revolution. Virtual education is a term describing online education using the Internet. This term is primarily used in higher education where so- called V IRTUAL U NIVERSITIES have been established. Virtual courses – a synonym is online courses – are courses delivered on the Internet. "Virtual" is used here to characterize the fact that the course is not taught in a classroom face-to-face but through some substitute mode that can be associated with classroom teaching. That means people do not have to go to the real class to learn. A virtual program (or a virtual course of studies) is a study program in which all courses or at least a significant portion of the courses are virtual courses. Students in virtual classroom typically acquire knowledge in a uni-directional manner first (e.g. by studying a video, reading a textbook chapter). Subsequent discussions of problems, solving exercises, case studies, review questions, etc. help the students to understand better what they learned before. Electronic media like a discussion forum, chat room, voice mail, etc. are often employed for communication. 1
