Questions concerning the conservation of a nonequivalent volume were posed to 65 nonconservers in terms of an imagined reward. Results indicated significantly more nonconservers demonstrated an awareness of empirical reversal or performed the preference relational operation correctly as compared to conditions that required comparative-relational…

Gifted (N=19) and average-functioning (N=19) hearing impaired adolescents were examined for ability to perceive that still water remains horizontal regardless of degree to which the container is tilted. Gifted Ss performed better on this task than average functioning Ss and the straight-sided containers induced more errors than containers with…

Study compared provoked and spontaneous one-to-one correspondence along with two tasks having more preceptual support for correspondence. In opposition to Piaget's predictions, the four levels of correspondence did not differ in difficulty for kindergarteners. (Author/SB)

This paper describes a set of studies carried out as part of a larger project on the development of children's concepts of matter and its changes. In this paper, the impact of visibility and familiarity of the process of dissolving on children's concepts is analyzed. Two different studies with kindergarten and third grade students were carried…

Local school boards must wrestle sucessfully with State and federal fuel allocation agencies to achieve top school priorities. (Author)

Tests designed to measure conservation, visual memory, and static and anticipatory imagery were administered to 1st and 2nd grade children. Conservation and memory correlated significantly with IQ. The different mental processes may be involved in the development of anticipatory imagery and conservation. (CS)

The effects of modeling and corrective feedback on the conservation of equalities and inequalities were studied. Both training methods were successful in teaching children to conserve. Trained children were also capable of generalizing their learning to new conservation tasks. (CS)

Uses a study of children's understanding of relational terms in conservation tasks to illustrate negligent or inaccurate reading of research reports. (ST)

In this and a previous study, only 29 percent of the subjects of mean age 13.6 had attained the conception of conservation of volume, a finding at variance with Piaget's earlier results. (Authors/CB)

Deals with the potential for saving energy and minimizing operating costs within existing school facilities and in attempts to modernize and expand. (Author)

Support for the operation of internal factors in cognitive development was provided by an obtained increase from first to second posttest scores. Two conservations were considered to be involved--conservation of the whole and of the part. (Author)

Describes the operation and benefits of equipment designed to salvage, collect, store, and generally conserve heat energy. (Author)

Reports the result of a case where the Sierra Club challenged the commercial development of a wilderness area. (AL)

Stimulus conditions were found to interact with conservation level and relation type. (MM)
