The WISC, Piagetian logico-mathematical and representational space tasks, the Frostig DTVP and a motor ability test were administered to elementary children at 3 age and arithmetic achievement levels to determine whether specific patterns of cognitive and/or spatial development were related to arithmetic achievement and whether patterns varied…

Evaluation of classification skills of 88 unimpaired children (grades K, 2, 4, and 6) were evaluated using the Iconic-Symbolic test (IS) of the Muma Assessment Program and follow-up interviews. Results found little relationship between the rationales the children reported using and the classification criteria presumed by the IS procedure. (DB)

Describes a study in which 383 children in grades 1 through 5 were individually interviewed to find out at what point they construct unit iteration out of transitive reasoning. Indicates that most children construct unit iteration out of transitive reasoning by fourth grade. Suggests a better approach to the teaching of measurement that presents…

To determine whether children possess representations and concepts of space before they acquire verbal descriptions of these, children's formation of symbolic representations of space and their acquisition of verbal referents for them were observed. It was found for subjects in the study that conceptual representations of space relations were…

Mathematical games designed for children from kindergarten to grade five using buttons as counters are described. Each game description includes a brief discussion of the number and mathematical concepts it teaches. (JD)

This study with 12 elementary school children with mild mental retardationship found that the relation between lexical knowledge and mental age depended upon the nature of the vocabulary test. Results suggested that mental age in this population was more strongly related to knowledge of abstract relational terms than to knowledge of labels for…

Proposes that children progressively recognize deeper and deeper similarities between their physical angle experiences, and classify them firstly into specific situations, then into more general contexts, and finally into abstract domains. Indicates that the standard angle concept first develops in situations where both arms of the angle are…

This study compared the spatial-geometrical abilities of 85 students (ages 5-13) with learning disabilities (LD) and 94 children without LD, matched for IQ and age. Generally, students with LD did not perform as well as same-aged students without LD, suggesting that LD students experience delayed development in this general spatial-cognitive…

Two experiments were designed to assess children's ability to understand recursive structures of thinking which include thinking about contiguous people, thinking about action between people, thinking about thinking, and thinking about thinking about thinking. In Experiment I, 32 second, fourth, sixth, and eighth graders were tested on eight tasks…

A cross-sectional study examined age differences in children's conceptions of early U.S. history. Students in grades 2, 3, 6, and 8 (n=281) were asked to respond to a question about how the United States became a country. Their essays show significant changes with age. Older students were more likely to include errors of historical fact in their…

A total of 100 second graders were pretested for conservation of length and weight. Fifty pairs were then formed, each pair consisting of one conserver and one nonconserver. During the second session, the children attempted to resolve their opposed answers on the conservation tasks and on two control questions as well. On both length and weight,…

Reports a study involving 35 learning-disabled boys attending full-time remedial schools and 35 matched normal achievers to investigate whether learning-disabled children differ from normal achievers in terms of logical thought and whether they exhibit decalages in their acquisition of Piagetian concepts. (BD/BR)

Shows that age or conceptual tempo are not related to the number of trials needed to reach the criteria for a learning task. Impulsive responders performed more poorly than groups of slow-inaccurate, fast-accurate, and reflective responders on the transfer of learning task. (RL)

This article discusses the feasibility of and the skills needed for teaching basic economic concepts such as supply and demand in an informal learning situation, in this case the simulation of an economic system based on barter. (CJ)
