A new diagnostic modeling system for automatically synthesizing a deep‐structure model of a student's misconceptions or bugs in his basic mathematical skills provides a mechanism for explaining why a student is making a mistake as opposed to simply identifying the mistake. This report is divided into four sections: The first provides examples of the problems that must be handled by a diagnostic model. It then introduces procedural networks as a general framework for representing the knowledge underlying a skill. The challenge (...) in designing this representation is to find one that facilitates the discovery of misconceptions or bugs existing in a particular student's encoding of this knowledge. The second section discusses some of the pedagogical issues that have emerged from the use of diagnostic models within an instructional system. This discussion is framed in the context of a computer‐based tutoring/gaming system developed to teach students and student teachers how to diagnose bugs strategically as well as how to provide a better understanding of the underlying structure of arithmetic skills. The third section describes our uses of an executable network as a tool for automatically diagnosing student behavior, for automatically generating “diagnostic” tests, and for judging the diagnostic quality of a given exam. Included in this section is a discussion of the success of this system in diagnosing 1300 school students from a data base of 20.000 test items. The last section discusses future research directions.

"Eco wittily and enchantingly develops themes often touched on in his previous works, but he delves deeper into their complex nature... this collection can be read with pleasure by those unversed in semiotic theory." —Times Literary Supplement.

The importance of this collection of writings of William James lies in the fact that it has been arranged to provide a systematic introduction to his major philosophical discoveries, and precisely to those doctrines and theories that are of most burning current interest. William James: The Essential Writings is a series of philosophical arguments on some of the most “obscure and head-cracking problems” in contemporary philosophy; the relation of thought to its object; the interrelationships between meaning and truth; the levels (...) and structures of experience; the degrees of reality; the nature of the embodied self; the relation of ethics, aesthetics, and religious experience to man’s strenuously and “heroically” active nature; and, above all, the structurization of the experienced life-world as the validating ground and origin of all theory; Bruce Wilshire has provided an introduction to William James’s thought on these and other related points which is at once both substantial and subtle.

Culture in Mind is an ethnographic portrait of the human mind. Using case studies from both western and nonwestern societies. Shore argues that "cultural models" are necessary to the functioning of the human mind. Drawing on recent developments in cognitive science as well as anthropology, Culture in Mind explores the cognitive world of culture in the ongoing production of meaning in everyday thinking and feeling.

The first full-scale history of cognitive science, this work addresses a central issue: What is the nature of knowledge?
