Instructors are constantly baffled by the fact that two students who are sitting in the same class, who have access to the same materials, can come to understand a particular chemistry concept differently. Variation theory offers a theoretical framework from which to explore possible variations in experience and the resulting differences in…

This paper defines a schema as a memory structure representing a general concept and its framework of associated concepts, and identifies the three processes by which learning can occur in individuals whose memories are schema-based, i.e., accretion, tuning, and restructuring. Ways in which schema might influence instructional design are then…

This paper details how memory protocols obtained in individual interviews may be translated to scores on several dimensions suggested by White. White's nine dimensions are: (1) extent, (2) precision, (3) internal consistency, (4) accord with reality, (5) variety of types of element, (6) variety of topics, (7) shape, (8) ratio of internal to…

The world presented to our senses is essentially continuous in space and time. The simplest observations of children have shown that we are not born with ways of "breaking up" the world. The structures of our knowledge must be developed, and the major issue this paper considers is how those structures develop. The discussion focuses on Jean…

Some feel that a persistent shortcoming of the collective views of human action is that they often advocate a view of the individual as merely a bearer or token for the group to which he or she belongs. These theories do not account for individual choice. This project attempts to arrive at a general critique of individualism, drawing on a number…

Ten individuals in the Educational Technology Program at the University of Northern Colorado served as subjects for this study, which was designed to: (1) identify cognitive networks of concepts within components of a system design model for expert and novice instructional developers, and (2) determine cognitive networks of concepts between…

Like any apparently novel approach to the basic epistemological problems of "knowledge," the constructivist ideas that have spread in the last 20 years continue to generate a host of negative as well as a few positive reactions. This document focuses on some aspects of Radical Constructivism, as distinct from "trivial"…

This description of the Structure-Mapping Engine (SME), a flexible, cognitive simulation program for studying analogical processing which is based on Gentner's Structure-Mapping theory of analogy, points out that the SME provides a "tool kit" for constructing matching algorithms consistent with this theory. This report provides: (1) a…

This paper analyzes Bogdanov's theory of knowledge as found in philosophical dialogues and essays. The style of Bogdanov's writing and his ideas on philosophy, science, scientific constructs, truth, human knowledge, objectivity and ethics are discussed. These ideas are compared to the constructivist view of knowledge. (CW)

This study reports two experiments which indicate that the processes of providing subjects with insightful representations of example programs and guiding subjects through an "ideal" problem solving strategy facilitate learning. A production system model (GRAPES) has been developed that simulates problem-solving and learning in the…

This paper presents preliminary results of research founded on the hypothesis that in real environments there exist regularities that can be idealized as mathematical structures that are simple enough to be analyzed. The author considered three steps in analyzing the encoding of modularity of the environment. First, a general information…

Reviews recent research in the area of mathematical understanding and compares and contrasts it with a model formulated for the growth of understanding. Uses the analysis of a transcript from an interview with an eight-year-old boy to illustrate the power of the model to describe and map the growth of his mathematical understanding. (18…

Secondary school geometry students have been found to have misconceptions concerning parallel lines. Correctional teaching programs did not seem effective in changing these misconceptions. This research describes an attempt to use teaching strategies which take into account current learning theory and which encourages students to be actively…

Contrasts recent views of learning and cognition with cognitive learning theories of the late 1950s and early 1960s. Maintains that Jerome Bruner's spiral curriculum approach, still valuable, is not sufficient to explain cognitive development. Proposes a lattice-like cognitive development structure, inviting differing paths of exploration. (CFR)

Reports on the assessment of student thinking in the area of commitment to the laws of conservation of matter and energy during a study of conceptual change among introductory chemistry students. States four conditions upon which strategies for conceptual change are based. (RT)
