"...The material is well structured and goes into succeeding levels of detail to describe what works and what doesn't. Cognitive aspects of how learning is delivered are thoroughly presented, using many charts and graphics to provide alternate means of viewing the text data. The text relies on extensive research performed by the author and other notable cognitive psychologists and instructional designers in the field. The book can serve as an excellent text for upper-level undergraduate and graduate courses in instructional design. It can also be used by professionals in the field, as a reference guide to what may be new cognitive research applied to the area of multimedia learning." --Bernice Glenn, Reviews.com (Computing Reviews)
Richard E. Mayer asks whether people learn more deeply when ideas are expressed in words and pictures rather than in words alone. He reviews 12 principles of instructional design that are based on experimental research studies and grounded in a theory of how people learn from words and pictures. The result is what Mayer calls the cognitive theory of multimedia learning.
