Abstract:

You may not find all the answers to your evolving questions, but the authors throughout the book do a good job of analyzing relevant research questions, defining the current state of Web-based education, and suggesting areas for continuing research. The book comes as close as you'll find to 'everything you always wanted to know about Web-based instruction,' with its in-depth coverage of today's Web education issues and research.
