This book contains several generally accepted principles in creating learning environments. I was actually shocked by an original thought somewhere near the end. The author is very vague, and contradicts himself several times.
He says "A major advantage of the Internet is that teachers do not have to worry about software and hardware issues as much as in other situations." This is absurd. It is a major barrier to learning. Teachers often have to cope with just those things before any learning on the subject matter can take place. It was not any easier in 1997 when this book was published -- it was more difficult because the technology was still young and far less stable, and because learners were not nearly as comfortable in the environment!
I feel that in his push to get his book to market early in the game, he sacrificed content and ideas for (what was then quite forward-thinking) technology.
You can learn something here, but watch your step.
