This article reports on a controlled study to investigate the efficacy of incorporating explicit discussions about the duality of human reasoning and its implications for learning in physics instruction. The central goal is to probe to what extent, if at all, such discussions improve student performance on tasks that tend to elicit intuitively…

The purpose of the study was to determine whether individual differences in at-risk 4th graders' language comprehension, nonverbal reasoning, concept formation, working memory, and use of decimal labels (i.e., place value, point, incorrect place value, incorrect fraction, or whole number) are related to their decimal magnitude understanding.…

HYPOTHESIZING THAT CONGENITALLY BLIND ADULTS WOULD SCORE LOWER ON TESTS OF ABSTRACTION THAN ADVENTITIOUSLY BLIND OR SIGHTED ADULTS, THIS STUDY TESTED 25 CONGENITALLY BLIND, 25 ADVENTITIOUSLY BLIND, AND 25 SIGHTED SUBJECTS. THE WECHSLER ADULT INTELLIGENCE SCALE (WAIS) VOCABULARY TEST WAS ADMINISTERED TO EACH GROUP AND RESULTS SHOWED NO SIGNIFICANT…

This study examines the relationship between a child's concept of geographic and territorial relationships and his competence on classification and class inclusion measures. Jean Piaget's stages of development and studies conducted by other investigators (Jahoda, 1964; Stoltman, 1971; Rand and Towler, 1973; Flavell, 1963; Asher, et al, 1971;…

The Conceptual Learning and Development (CLD) Model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known object when it appears in a different spatial, time, or sensory perspective; (3) classificatory--generalizing that two items are alike…

The Goldstein-Scheerer Tests of Abstract and Concrete Thinking are reviewed. This evaluative summary supplements several reviews in the Mental Measurements Yearbook series. The Goldstein-Scheerer tests are used by clinicians and researchers to distinguish normal individuals (those able to engage in two qualitatively different levels of cognitive…

The purpose of this study is to show that there is a gradual and measurable development in the drawing of space representation concepts. A further purpose is to show that children's drawings of a village (which represent relations among concepts) may be a better measure of their conceptual maturity than their drawings of a man (which represent a…

A four-year longitudinal study of concept attainment and uses of concepts, as specified by the Conceptual Learning and Development Model, is described. Data collected during the first two years were based upon the assessment of the concept, equilateral triangle. The assessment battery was administered to 351 children (grades K, 3, 6, and 9) in…

In order to investigate the hypothesis that the conceptualization of sequence precedes that of simultaneity in child development, and to explore the use of elicited imitation in studying lexical acquisition, 32 subjects between 3 and 5 years of age were asked to verbally imitate a list of sentences. The constructions combined simple and reverse…

Performance in concrete and abstract tasks is examined systematically by varying the degree of abstractness of problem-solving and concept formation tasks. Four forms of a problem solving test were constructed. Each form of the test presented problem situations through four different modes: verbal stories, picture-book, color slides,…

Thirty-seven normal and 33 gifted children from kindergarten classes and 26 retarded children from special classes with mean mental ages of 76 months, 80 months, and 72 months respectively, were initially tested for their understanding of the terms more, same, and less. All who had failed conservation of substance pretests using juice, sand, clay,…

This document accompanies the Conceptual Learning and Development Assessment Series III: Tree, a test constructed to chart the conceptual development of individuals. As a technical manual, it contains information on the rationale, development, standardization, and reliability of the test, as well as essential information and statistical data for…
