That students will eventually use computers in place of traditional textbooks is almost certain. Just watch the eight-year-old children at your local elementary school pulling their backpacks (now on wheels). Will the digital textbook become more than a CD-ROM of the print version? First, like most other education technologies, it will be an adaptation of business or entertainment technology. More than anything else, it will probably resemble today's Tablet PC. It will be carried into the classroom under our arms or in small book bags. There are other physical aspects that might be explored about what digital textbooks will look like, but the more interesting question is "How might the concept of the textbook change, if it becomes digital?" This question assumes that the textbook is still an evolving tool. This is an interesting issue, as it exposes a wide variety of new possibilities in learning experiences for students. In order to examine these possibilities, the author targets three qualities of networked digital information that are uniquely compelling for teaching and learning. They are: (1) Digital Information Is Rich and Interactive; (2) Digital Information Is Interconnected; and (3) Digital Information Can Be Expressed Compellingly. The author also asks if teachers are beginning to construct the online digital textbook for their students, might there be some value in asking students to assemble their own textbooks? Is there some relevance in the 21st century to make students producers of their learning resources rather than mere consumers?
