This article reviews progress toward the development of a cognitive theory of aptitude for learning and presents descriptive and precriptive goals for aptitude theories. Preliminary hypotheses about the nature of cognitive processes in aptitude for learning from instruction are reviewed. Twelve constituent points of the descriptive theory are…

Argues that style and self are inextricably bound together in a writer's work, and the voice that they create emerges only after a certain level of writing development has been reached. This happens when the writer has been thoroughly immersed in a context and has had plentiful experience in a specific form of expression. (HOD)

Mastering the basic number combinations involves discovering, labeling, and internalizing relationships, not merely drill-based memorization. Counting procedures and thinking strategies are components, and it may be that using stored procedures, rules, or principles to quickly construct combinations is cognitively more economical than relying…

The author first corrects Baroody's description of the network retrieval model for basic number facts, in which facts are stored in memory and retrieved as needed. He then indicates weaknesses in Baroody's argument. (MNS)

Description of several computerized tutoring systems is organized around types of knowledge any tutor must possess--subject area, student's information, and how to teach and communicate. Data and control structures of Meno-tutor are described to illustrate use of artificial intelligence to model the student, a domain, and teaching strategies. (MBR)

Describes some of the key intellectual actions that underlie the process of revision in writing and that most affect its practice. Provides a working model of revision and discusses diagnosing problems and devising solutions. (HTH)

An empirical analysis of the relationship between science reasoning skills and the amount of information acquired during science learning as predicted by a neuromathematical model of information processing is presented. Subjects were 93 adolescents (mean age of 15.4 years old) with a IQ range of 91-142. (Author/JN)

Describes recent developments in brain science with implications for persons whose research interests are in science education. Discusses new conceptual models, useful methods and techniques, and how neuroscience paradigms and technologies can be applied to teaching and learning. (JM)

In three experiments, differences between good and poor writers were examined on six cognitive-processing tasks: ordered letters, ironic memory, letter reordering, word reordering, sentence reordering, and paragraph assembly. Both college and high school students were studied. Significant differences were found in abilities to hold and…

Building on Bloom's, and subsequent educational taxonomies, a larger, synthetic, theoretical basis, called the process hierarchy theory, is developed. Its relationship to general systems theory and its metatheoretical context are described. A general methodology for empirically testing aspects of the theory using mathematical modeling is explored.…

Provides an overview of the recent changes in the theoretical conception of memory and language comprehension and how these are influencing reading research, assessment, and teaching. (FL)

Describes the construction of a knowledge representation from the identification of the problem (nephrotic syndrome) to a running computer simulation of causal reasoning to provide a vertical slice of the construction of a cognitive model. Interactions between textbook knowledge, observations of human experts, and computational requirements are…

Describes a new theoretical model of the learning process produced by the computer's strict reliance on procedure and its unique methods for managing data. The implications of this model for mathematics learning are illustrated through an experimental paradigm comparing the problem-solving skills of an expert and a novice. (MBR)

A model of subtraction development and the computing difficulties and research issues suggested by the model are outlined. Demands of simultaneous processes, difficulties with informal subtraction, and the impact on the counting-up procedure are discussed. (MNS)

Discusses learning behaviors where the "picture superiority effect" (PSE) seems to be most effective in biology education. Also considers research methodology and suggests a new research model which allows a more direct examination of the strategies learners use when matching up picture and text in efforts to "understand"…
