Query: Why to Buy This Book

There is only one good reason to buy this book: it is required for your degree plan. It tries to cover instructional design and web based training, but does neither well. For example, Driscoll spends a lot of text explaining the difference between a Virtual Synchronous Classroom and a Virtual Asynchronous Classroom. She describes each in great detail. The difference: in the first, all students participate simultaneously; in the second, they participate at their own convenience. For instructors, the difference lies in the amount of time spent monitoring the class. Other topics are chunked to the point of becoming meaningless.After six years of higher education and 10 years training adults, this is only the second book I have ever wanted to sell at the end of a semester....END
