Research has shown the majority of students who have completed a university calculus course reason about the definite integral primarily in terms of prototypical imagery or in purely algorithmic and non-quantitative ways. This dissertation draws on the framework of Emergent Quantitative Models to identify how calculus students might develop a…

The periodic table is recognized as one of the most powerful tools in science. While it is included in virtually all high school and undergraduate general chemistry curricula, it remains a mystery to many chemistry students who find it impossible to decode. Students are often able to predict periodic trends concerning atomic radius, ionization…

We report on interviews conducted with twenty-one elementary school children (grades 1-5) about a number of Earth science concepts. These interviews were undertaken as part of a teacher training video series designed specifically to assist elementary teachers in learning essential ideas in Earth science. As such, children were interviewed about a…

To determine concept usage performance of the mentally handicapped when confronted with familiar items used in the concept usage tasks, 32 common concepts were presented to 25 educable mentally handicapped and 22 non-retarded subjects. From the responses to this number of referents task, a concept usage task was constructed which required choosing…

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…

One of the most typical ways in which people learn is by inferring general rules from examples. In recent years, significant progress has been made toward understanding how learning from examples can occur, determining when it does occur, and identifying conditions that promote it. This paper reviews these results and then suggests a program of…

The article describes a study to determine how instruction on the distinction between two theoretical ideas will affect the intake, interpretation, and recall of new information related to but different from the first. (Author/SB)

Specific teaching strategies to help hearing-impaired secondary students comprehend abstract concepts include (1) pinpointing facts and fallacies, (2) organizing information visually, (3) categorizing ideas, and (4) reinforcing new vocabulary and concepts. Figures provide examples of strategy applications. (DB)

This paper examines the area of teachers' practical arguments (arugments consisting in the search for a plan of action), considering questions such as: How does rationality manifest itself in practice, and in specific human practices like teaching? Is practical reasoning in teaching moral? Do values of theoretical reasoning, such as universality,…

This study examined the effects of certain contextual linguistic variables on the logical performance of subjects in grades 4, 6, and 12 of selected British Columbia schools as well as some theoretical problems underlying assessment of the development of logical abilities. The task consisted of 27 syllogistic problems based upon the information…

Fluid intelligence (Gf) is a general relation-perceiving capacity determined by each person's cortical, neurological connection count development. Its processes are involved in reasoning, concept formation and problem-solving, where acculturation has little effect. Crystallized intelligence (Gc) manifests knowledge and general comprehension,…

An extensive bibliography on teaching thinking skills is presented. This bibliography incorporates from an earlier one (1989) the available relevant references in the field of cognitive education as well as new references that have appeared since early 1989. This field of cognitive education is expanding at such a rapid rate that no bibliography…

College students (N=52) were given unfamiliar or novel problems (written and interview responses) to determine how they characterize living things, criteria they use to distinguish between living/dead/nonliving, and to determine if their idea of life included the interrelationship between organisms and biosphere. Results and implications are…

Presents the results of three studies examining children's conception of the mind itself as an independent, active entity. Findings revealed a developing ability in children to interpret and produce statements personifying the mind and provided considerable evidence of children's movement toward a conception of the mind as an active agent…

This study sought to determine the basis for young children's understanding of fundamental addition and subtraction processes, and to expose any limitations on such arithmetic reasoning. Thirty-six two-year-olds and 36 three-year-olds participated in six experiments which examined children's relational quantity judgments about pairs of arrays in…
