The framework for this paper is a recently developed theory of abstraction in context. The paper reports on data collected from one student working on tasks concerned with absolute value functions. It examines the relationship between mathematical constructions and abstractions. It argues that an abstraction is a consolidated construction that can…

This paper presents two puzzles that have emerged in a series of completed and ongoing studies at Queen's University, Ontario. These puzzles concern teachers' professional knowledge, a term used to refer to the non-propositional forms of knowledge assumed to be of importance to professional action. This research assumed that the professional…

Children's natural curiosity should be more adequately satisfied, resarch has suggested--especially in grades 4 to 6. Traditionally, the scope and sequence approach which is a learning-what-others think or have thought rather than a learning-to-think-for-oneself method begins during the middle school years. It is interesting to observe that…

A theory of adult cognitive development which includes two post-formal operational stages is described. The paper is divided into three sections. The first section provides background for discussion of the theory. A case study in which various employees in a hypothetical organization react to a problem is provided. Examples of pre-logical,…

Metaphor, ethnography, and other qualitative alternatives to the traditional goal-based experimental approach to evaluation have been presented recently. Among the issues associated with the experimental approach are those of preordinate specification and explicit definition. Though the former has received much attention, the latter requires…

Discussed are the concepts of intuition, the general properties of an intuitive knowledge, and the classification of intuitions as problem solving of affirmative. An example of intuition using multiplication and division is described in some detail. (MNS)

A brief survey of models in dealing with various types of understanding is given. Then a hybrid model, which proved inadequate for describing understanding, is outlined. Finally, four levels of understanding are discussed: intuitive, procedural, abstract, and formal. The concept of number is used to illustrate these levels. (MNS)

Nihilism is the fundamental movement in the history of the West. Materialism is a symptom of nihilism. Materialism is the view that all meaning has gone from the cosmos, nature, and culture. Values are objective, explicit options which imply the existence of choice. (JN)

Descries professional overspecialization and education's overemphasis on the acquisition of formalized information. Discusses the capabilities of the hemispheres of the brain and the problems caused by focusing on only the left hemisphere. Illustrates intuition and abstract patterns. Suggests that recognition of laterality will advance education…

Comments on Flavell's paper (PS 522 962) presented in the same issue. Stresses some of the positive aspects of preschoolers' conception of thinking, and raises questions about the relatively negative portrait of young child's introspective abilities. Discusses evidence of introspection among preschoolers, and underlines the special, and…

Comments on Flavell's paper in this issue. Examines the paper's findings on three different aspects of children's knowledge about thinking: their ability to differentiate thinking from other activities, their awareness that thinking is always going on in people's minds, and their capacity for introspection into their own thinking. Argues that…

Visual learning, the capacity to construe meaning from visual images and to create meaningful visual forms, distills complex information and presents information directly. It plays an important role in development of the ability to abstract and decode. (SK)

Responds to the conversation of two eminent compositionists with Noam Chomsky. Discusses the alleged literary crisis, sensible prescriptivism versus linguistic permissiveness, police and thought control, intellectually interesting versus humanly significant topics, and rhetorical theory. (PRA)

For a specialist from the communication discipline, studying with Alexander Luria, who had been a colleague of Lev Vygotsky in the l920's, provided insights into the Soviet psychologist's ideas about mediation and mind and how writing fits into those ideas. According to Luria, Vygotsky was a methodologist who worried about what kinds of methods…

A multidimensional model of the growth of moral reasoning is described that is significantly different from those proposed by Kohlberg and Piaget. A study that tests several aspects of the model on university students is reported. The suggestion that well-developed chains of reasons are a prerequisite for the emergence of metaethical reasoning was…
