The Virtual Classroom,Learning Without Limits Via Computer Networks
This book describes the evolution of the Virtual Classroom from an idea to a reality. A primary emphasis is on evaluation tools and procedures, which enables the reader to assess the extent to which the objectives of this new use of computers were attained. Extensive descriptions are provided of the software and of the collaborative learning processes that can be supported by software. Pitfalls and problems as well as advantages and successful uses of the technology are described. Finally, the book looks forward from these initial experiments to the possibilities for the use of this technology to expand educational opportunities in the 21st century.
