Emergent technologies present new wrinkles for evaluators in an already lumpy field. This book smoothes out those wrinkles, providing a rich mix of theory and practice, with sound guidance about why, how, and what-if. I particularly like the grounding in the literature, international references, and frequent case studies.

Interactive Learning Systems Evaluation fills a large gap in evaluation textbooks. The book provides methods that will allow much more rigorous examination of Instructional Technology that has been typically done to date. In addition, graduate students were very positive about the text when using a trial version of this book in a class on evaluating instructional technology. The methods described in the book will go a long way to improve the caliber of evaluation and research in this important area.

A lot of time and money have been invested in the development of interactive educational products in the last decade and yet effective evaluation has rarely been carried out. On reason is that there has been too much mystique surrounding the term 'evaluation.' I have worked with academics in the design and evaluation of such products for ten years, and I would have loved to have had access to a book like this during that period. Interactive Learning Systems Evaluation demystifies evaluation and provides clear and accessible guidelines to assist all parties involved in educational product development to optimize the development process itself and the likelihood that student learning will be enhanced. A 'must' for every production group and educational development unit.

Even very experienced interactive Learning System developers struggle with evaluating the product of their labors. And the more complex the program, its topics, and its audiences, the more difficult the evaluation. Drs. Reeves and Hedberg have provided a comprehensive, valuable, and highly useful guide for evaluating a broad range of interactive learning systems, from the simple to highly complex.

At last there is a definitive guide for teachers and faculty involved in evaluation and research relating to instructional technologies. Reeves and Hedberg have given us a very readable and thorough guide for such activities. This book should be mandatory for all faculty and students involved in learning technologies research.
