The development of scientific concepts and methods that supported analyses of individual cognition and learning occurred during the 1950s, 1960s, 1970s, and 1980s, with outstanding contributions by Newell and Simon (1972), van Dijk and Kintsch (1983), and others, providing an impressive and rapid scientific advance. At the same time, another…

About two decades ago, Donald Stokes published "Pasteur's Quadrant" (Stokes, 1997). Stokes proposed that the motivations of different research projects can be understood as a two-dimensional system, with higher or lower concern for improving technology and practice on one dimension and higher or lower concern for improving fundamental…

Son and Goldstone (2009) provided orienting activities intended to increase personal engagement, and these activities reduced participants' transfer based on concepts of signal detectability theory. I offer a theoretical interpretation that differs from theirs. First, instead of assuming that activity is contextualized in some conditions and not…

Earlier Analyses are shown to involve special cases of the equations developed here; also that a general four-state chain has the same parameter space as an all-or-none model if and only if its representation with an observable absorbing state is lumpable into a Markov chain with three states.

Discusses (1) neobehaviorist theory and analysis of response probability, (2) discrete models of qualitative changes in knowledge and stages of processing, and (3) programmed simulations of the detailed structure of knowledge and cognitive processes. Comments on the prospects for developing significant new understandings of learning during the…

Examines the relations between research about processes of learning and thinking and educational practices that attempt to achieve that aim. Three research perspectives, behaviorist, cognitive, and situative, that characterize thinking and learning to think differently are discussed. It argues that the situative perspective can provide a framework…

In the pair of experiments reported here the authors investigated the relationship between meaningfulness of problem statements and subjects' use of these statements in problem-solving tasks. Subjects (96 university students) were required to memorize meaningful formulae such as "volume = area x height" or corresponding symbolic formulae such as…

By 1960 there was a strongly developed theory of learning in which learning was considered as change of behavior. Neobehaviorist theories and then formal stochastic models analyzed processes in which probabilities of responses are altered. In the 1960's, analysis of learning as a discrete change between states of knowledge or stages of processing…

Presented is an introduction to the operation and mechanics of the ACTP production system, a version of Anderson's (1976) ACT system. ACTP is already in use modeling geometry theorem proving and counting of a set of objects, and has been identified as a potentially useful programing framework for developing models of the cognitive processes used…

Discusses situative perspective as a framework for integrating issues of theoretical assumptions, educational practices, and educational research. In this perspective, the focus of theoretical principles is at the level of interaction among people and between people and their environments. Contains three pages of references. (MMU)

Discussed is one "quite general" attribute that can differentiate problem representations: the kinds of entities that are included -- the cognitive objects that the system can reason about in a relatively direct way, and that are included continuously in the representation. The ontology of a domain is significant for four reasons. First,…

Argues the differences between situative and cognitive views of learning, as proposed by J. R. Anderson et al. (1996), are more conceptual than empirical. It clarifies these differences by inferring questions to which the Anderson discussion provided answers, identifies presuppositions of those questions, and states the different presuppositions…

Thinking-aloud protocols of human problem solvers working on geometry problems are presented and discussed. Protocols were obtained from six individuals working on nine different problems in which constructions were used. Nineteen protocols are presented with annotation and discussion, and other protocols are summarized. The primary purpose of the…

Problems were presented to 13 university students in which letters were to be added or subtracted (e.g., B + D = ? or F - ? = D). After each problem, each subject gave a retrospective protocol indicating the way in which the problem was solved. Models of performance by each subject in each experimental session shared major properties; choices by…

Research was conducted investigating properties of skill in learning, in the domain of elementary algebra. Thinking-aloud protocols indicate that early knowledge of the subjects studied was fragmentary, rather than involving systematically flawed procedures. Computational models, developed to simulate observed errors, focused on the role of…
