The development of rich, reliable, and robust measures of the composition, structure, and stability of student thinking about core scientific ideas (such as natural selection) remains a complex challenge facing science educators. In their recent article (Nehm & Schonfeld 2008), the authors explored the strengths, weaknesses, and insights provided…

It has been suggested that the enterprise of developing mechanistic theories of the human cognitive architecture is flawed because the theories produced are not directly falsifiable. Newell attempted to sidestep this criticism by arguing for a Lakatosian model of scientific progress in which cognitive architectures should be understood as theories…

Viewing truth and knowledge as intertextual phenomena, the theory of rhetoric-as-epistemic presented in this paper defines the consensus model as unanimity and the "discourse community" model as involving primary texts (rather than people). A theory of intertextual reality and knowledge is developed, based on five major assertions: (1)…

What is the nature of latent predictors that facilitate diagnostic classification? Rupp and Templin (this issue) suggest that these predictors should be multidimensional, categorical variables that can be combined in various ways. Diagnostic Classification Models (DCM) typically use multiple categorical predictors to classify respondents into…

Discusses various views of domain-specificity. Argues that it is time to move beyond an acknowledgment that constraints on the way knowledge is represented influence the way in which new learning proceeds. Directions for future research are pointed out. (RH)

Hypothesizes that writing systems affect cognitive strategies at a deeper level of human information-processing than is generally accepted in present day psychology. Discusses why almost all varieties of alphabets, syllabaries, and consonantal systems have been written to the left while vocalic systems have been written to the right. (JD)

Claims that people determine whether something is a member of a given artifact kind by inferring that it was successfully created with the intention that it belong to that kind. Discusses function-based and intentional-historical accounts of artifact concepts. Concludes that a rich set of inferential capacities is needed to constitute a theory of…

Argues that the unconscious mind plays a central role in argumentation. Discusses the nature of the unconscious and analyzes invention, focusing on rules theory. Claims that argument reception is controlled by the unconscious. Identifies a series of basic issues needing investigation. (JD)

Description of expert system development focuses on identifying the problem, or knowledge, domain, and discusses three methods for defining the domain: (1) brainstorming, (2) concept analysis, and (3) information processing analysis, which describes cognitive processes. The techniques are illustrated by a description of an auto manfacturer's sales…

Illustrates distinctions among kinds of knowing. Distinguishes knowing-to from other forms of knowing, and explores implications of that distinction for teaching and learning mathematics. Proposes that knowing-to act in the moment depends on the structure of attention at the moment, and on what one is aware of. (Contains 75 references.)…

A major error in cognitive science has been to suppose that the meaning of a representation in the mind is known prior to its production. Representations are inherently perceptual--constructed by a perceptual process and given meaning by subsequent perception of them. The person perceiving the representation determines what it means. This premise…

Discusses the enigma of what and how people know apparently trivial information. Presents an experiment, expected answers, and actual responses to grammar questions to determine the degree of common knowledge in professional trivia. Concludes that further research may bring a clearer understanding of the "tradition" of language teaching…

A model of mental representations is developed and shown to provide a framework for interpreting research. The content of awareness is characterized as a model of the world capable of simulating future events, anticipating present events, and thereby formulating appropriate actions. Properties of awareness and of underlying processes are…

One of the major trends occurring in the area of task analysis methodology is the development of better methods to analyze cognitive tasks, including new methodologies for analyzing the ways in which knowledge should be structured within a student's head to facilitate given types of performance. The most important trend is the integration of task…

Good thinking can be placed within a descriptive framework which includes a state of doubt about what to do or believe; goal, possibilities, and evidence seeking; and evidence use. The framework is useful in describing all types of thinking, although the search process may differ in the degree of control the thinker has over his search. Examples…
