This study investigates the relationships between the ITPA, which measures the development of specific language abilities, and the CAK, which is the most readily available measure of the development of conservation, in a sample of non-pathological preschool children. (Author)

Children were grouped according to ability to conserve number and then randomly assigned to training on arithmetic concepts or playing a game. The research hypothesis that there would be an interaction effect between conservation and effect of treatment was not confirmed. (SD)

The paper describes an experiment in which 52 deaf children (7-19 years old) and 36 normal hearing children (7-16 years old) were given several Piagetian conservation tasks to determine if the conventional instructions are the basis for conservation failure in deaf children and to examine the order in which deaf Ss acquired various forms of…

The question of how Piaget selects mathematical concepts for his theory is addressed as a problem which may have contributed to a misinterpretation of the relevance of conservation studies for mathematics education. A new form of pseudo-conservation is discussed in which nonconservers of length are able to pick out strips of equal length from an…

Included in this annotated bibliography are entries on the role of the social sciences in the discipline of forestry. Four major categories of entries are included: (1) social science applied to forestry at large; (2) social science applied to forestry's productive agents; (3) social science applied to forest production; and (4) social science…

This study investigates the effects of a training procedure on children's conservation. Volume conservation was induced in twenty-one 8-year-old non-conserving children by a procedure that combined two sources of conflict. First, the competing schemes used in making decisions on volumes were aroused; second, the non-conserver was made aware of a…

Twenty-four profoundly deaf children (7 to 13 years old) from a residential school were presented with conservation problems of liquid, matter, weight, and volume. Analyses of variance showed that age was significant beyond the .01 level and type of task (conservation) at the .25 level. No significant sex effect was found. Differences among means…

In two experiments (N=210) conservers, transitional conservers, and nonconservers were directed to lie or pretend to other children that their judgments and explanations of a series of conservation problems were the opposite of what they really were. Nonconservers and transitional subjects in both studies made large and significant gains in…

The purpose of this study was to explore among first grade children the relationship between achievement in mathematics and the understanding of the principles of conservation, seriation, and categorization as these are defined by Jean Piaget. Research instruments included those designed by Piaget and the Greater Cleveland Mathematics Tests.…

It was hypothesized that the acquisition of conservation behavior would be facilitated when stimuli were more concrete than abstract. Eighty white second graders were randomly assigned to four groups and presented with three conservation-of-weight problems. Clay balls and the conservation transformations were either shown, demonstrated, and…

The child's ability to identify numerousness as a property of a set, distinct from all the other properties of that set, may be a prerequisite to conservation of numerousness of sets. To test this theory, 11 lessons designed to develop the ability to identify properties of objects and of sets of objects and to represent length and numerousness…

Conservation of a property is the ability to recognize that the property in question hasn't altered, even though other properties have been varied. It is Piaget's view, confirmed by empirical evidence that children are not able to conserve length until age 7 or 8. Recent concern over confounding variables led to the present study in which the…

The Minnesota School Mathematics and Science Teaching (MINNEMAST) Project is characterized by its emphasis on the coordination of mathematics and science in the elementary school curriculum. Units are planned to provide children with activities in which they learn various concepts from both subject areas. Each subject is used to support and…

The relationship between scores on three area conservation tasks and scores on two area measurement tasks, as affected by two sequences of presentation of Piagetian tasks to children in grades one through three, was investigated. The five area tasks were administered individually to 168 children ranging in age from six years five months to nine…

The purpose of this study was to investigate the effects of practice on relevant components of selected operations on a child's ability to conserve substance and weight. A group of 108 children between the ages of five and seven was selected from one school and pretested for conservation of weight and substance. The 48 non-conservers were then…
