Maternal involvement effects on symbolic play development in toddlers were investigated. Sixteen mother-child dyads were observed at bimonthly intervals in a free-play setting during the period from 20 to 28 months of age. The complexity and length of play episodes increased when the mother was available to play with the child. (Author/BN)

Employs latent partition analysis (a multivariate technique) to reveal pre/postcognitive structure of freshman engineering students (N=70) taking general chemistry. Similarities and dissimilarities among high and low scorers are discussed. Arguments for use of this statistical techniques are presented. (DH)

This commentary reflects on the research methods used in EC 602 984 and suggests an alternative approach for investigating dysfunctional cognitions associated with depression in special populations. The paper recommends a multimeasure approach to depression, abandonment of reporting mean differences as significant or nonsignificant, and focusing…

Post-formal operational thought is characterized by both relativism and dialecticism. To examine age differences across adulthood in relativistic and dialectical thought, and to determine whether formal operations are necessary but not sufficient for these forms of thought, 20 young (mean age, 19.6), 20 middle aged (mean age, 46.2), and 20 older…

Presents a conceptual framework of second-chance systems analyzable in terms of several basic parameters (targeted population, declared goals, processes, options for students, evaluation criteria, and implications for the regular system). Uses this framework to analyze an Israeli external high school, the subject of a large-scale study. Includes 3…

Reports four experiments focusing on Piaget's claims that conservation and transitivity concepts are experienced as logically necessary truths. Two experiments examined feelings of certainty and necessity in college students presented with Piagetian tasks. Two other experiments extended these procedures to children and the issue of developmental…

Considered are two commonly used techniques, the interview and word association techniques. Highlighted is a third technique called the repertory grid. This third technique can be used to interpret students' knowledge based on an explicit, psychological theory of human behavior. (Author/CW)

Strategic communication scholars agree that planning is critical to human action. An investigation tested plan modification aspects of cognitive planning theory. Two experiments tested whether success and failure of a plan served as predictors of plan modification and whether individuals can accurately predict whether and how they will modify a…

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…

Decisions assume some level of interdependency between knowledge and know-how, these being distinct realities. Knowledge refers to the understanding one has of a phenomenon while know-how refers to one's capability of actions on a phenomenon. Information can be related to decision only by transforming data which is held in a semiotic memory into…

Administrative scientists superimpose analytic frameworks on their observations when trying to make knowledge meaningful. The generation of knowledge should be seen as an essentially interpretive and subjective activity. An awareness of this fact may encourage a view of scientific progress that is reinforced by the social context in which research…

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…

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…
