Computer-assisted instruction evolves toward intelligent tutoring systems (ITSs) by passing three tests of intelligence. First, the subject matter, or domain, must be "known" to the computer system well enough for this embedded expert to draw inferences or solve problems in the domain. Second, the system must be able to deduce a learner's approximation of that knowledge. Third, the tutorial strategy or pedagogy must be intelligent in that the "instructor in the box" can implement strategies to reduce the difference between expert and student performance. At the foundation of ITSs, therefore, one finds three special kinds of knoweldge and problem-solving expertise programmed in a sophisticated instructional environment. This book examines these knowledge foundations - expert knoweldge, student diagnostic knowledge, and the instructional or curricular knowledge - in detail. This book also describes (a) how these kinds of knowledge are embodied in computer-assisted instructional environments; (b) how these systems accrue the advantages of advanced computer interface technologies; (c) how ITSs will emerge in the real world of complex problem solving; and finally (d) how researchers must learn to evaluate the effectiveness and overall quality of these dynamic systems in a world where one day machine tutoring will be taken for granted. The purpose of this chapter is to introduce the major research issues and development themes that the primary authors - John Anderson, Kurt VanLehn, Henry Halff, Richard Burton, James Miller, William Johnson, David Littman, and Elliott Soloway - explore and amplify."
