People generally use the Web to access passive information. Educational materials on the Web are generally fixed presentations of predetermined content.
Intelligent books are different, because the information they present is only partly composed by the authors: most of an intelligent book is dynamically constructed and accumulated through conversations with its readers. More concretely, an intelligent book understands the principles and strategies of the subject matter, and uses those to answer questions, to fill in details, and to accumulate new examples as suggested by the conversations with its readers.
This project is investigating the general system infrastructure required to write and present intelligent books with specific case studies in material for teaching electronic circuits and discrete mathematics.
The current state of the project can be followed on the Intelligent Book website.
