We applied a mixed-method research design to investigate the patterns of reasoning used by novice undergraduate chemistry students to classify chemical substances as elements, compounds, or mixtures based on their particulate representations. We were interested in the identification of the representational features that students use to build a…

Science classes are full of abstract or challenging concepts that are easier to understand if an analogy is used to illustrate the points. Effective analogies motivate students, clarify students' thinking, help students overcome misconceptions, and give students ways to visualize abstract concepts. When they are used appropriately, analogies can…

In his influential book "Dialogues with Children" (1984), Gareth Matthews presents strong evidence that children as young as six can and should engage in philosophical discourse. His findings form the basis of this article, a theoretical and practical guide for parents and teachers seeking respectful and creative ways to encourage…

Findings from an on-going design experiment within a year-long graduate course for middle school teachers of mathematics are reported. The purpose of the course was to help teachers assist students in transitioning from arithmetic to algebraic reasoning. Goals included developing teachers' ability to interpret, compare, and generalize across…

A model for processes of abstraction, based on epistemic actions, has been proposed elsewhere. Here we apply this model to processes in which groups of individual students construct shared knowledge and consolidate it. The data emphasizes the interactive flow of knowledge from one student to the others in the group, until they reach a shared…

The purpose of this study was to examine the Wechsler Intelligence Scale for Children-Revised (WISC-R) profiles of two treatment populations and present a theoretical rationale for using adventure therapy. Data for the first group were obtained from the psychological testing records of 150 randomly selected inpatients (81 males, 69 females)…

A discussion focusing on the abstractness of analysis in phonology, debated since the 1960s, describes the issue, reviews the literature on the subject, cites specific natural language examples, and examines the extent to which the issue has been resolved. An underlying representation is said to be abstract if it is different from the derived one,…

A unit on animals was taught to 64 preschool children (44 in an experimental group and 20 in a control group). Children in the experimental group were taught nine major concepts over four levels of abstraction (designated as superordinate, intermediate, subordinate, or particular levels). Each concept was presented by means of an advance organizer…

The Wechsler Adult Intelligence Scale was administered to 30 male criminally insane patients and 15 violent convicts. The latter had similar subtest score configurations and the mean similarities ratio score for the violent group was significantly lower than that of the nonviolent group. (Author/SE)

Suggests that the intellectual school of thought that emphasizes the strength of black families has misled the black movement away from an attack on the suffering of blacks in their family situation and related conditions; i.e. the psychological effects and social destruction of unemployment and under employment of black males. (Author/AM)

Analogical reasoning is frequently used in acquisition of mathematical concepts. Concrete representations used to teach mathematics are essentially analogs of mathematical concepts, and it is argued that analogies enter into mathematical concept acquisition in numerous other ways as well. According to Gentner's theory, analogies entail a…

This paper analyzes how philosophy enters into inquiry in teacher education, in writings by both philosophers and nonphilosophers. Examples illustrate philosophical activities (such as conceptual and logical analysis, positing and explaining distinctions, evoking shared ideas and values), as well as showing that philosophy plays an important part…

Developed in response to deficiencies in verbal and quantitative skills demonstrated by students entering New Jersey colleges and taking the New Jersey Basic Skills Placement Test, this overview is designed to help interested educators orient themselves to the important and rapidly growing field of thinking skills instruction. The Task Force on…

An important task for literature teachers is to develop students' capacity for abstract thinking so that it can be employed on problems at will and by choice. The first process of abstract thinking is one which enables a person to see a connection between A and B, including processes of cause/effect, making analogies, or making comparisons.…
