Introduction: Subitizing, a quick apprehension of the numerosity of a small set of items, is consistently utilized to support early number understanding. Perceptual subitizing is the innate ability to recognize less than five items without consciously using other mental or mathematical processes. Conceptual subitizing, which requires higher-level…

A core challenge for team innovation is the successful translation of creative ideas into innovation through implementation. This study examines the tension between internal and external team resourcing behaviors that account for how teams translate their creative ideas into implemented innovation. Drawing on conservation of resource theory, we…

We probed the impact of two teaching strategies, "guided inquiry" and "argumentation," on students' conceptual understanding of the conservation of matter. Conservation of matter is a central concept in middle school science curriculum and a prerequisite upon which rests more complex constructs in chemistry. The results indicate that guided…

Background: Traditional studies of children's mastery of conservation of volume in liquids and solids have reported that conservation of volume in liquids is an easier concept to master than its solid counterpart. However, the two concepts have been assessed in different ways, with the assessment tool for solids employing a more complex process.…

Purpose of study was to investigate the applicability of Piaget's theory and methods to the study of conservation in nonhumans. Two out of four subject monkeys achieved stringent and statistically significant performance criteria in sameness-difference judgment tests and showed significant generalization in the fewest possible trials.

First graders, pretested on conservation tasks, were assigned to groups consisting of one conserver and one nonconserver. Groups then had to give a joint response. Nonconservers yielded more often to conservers. Subsequent tests indicated nonconservers improved on the tasks. (ST)

Examines questions about reported findings that the natural number concept derives from a prior understanding of ordination rather than a prior understanding of cardination. (GO)

The relationship between concrete operational thought and concept attainment was investigated in second grade students. (GO)

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…

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)

Investigates the developmental priority of identity conservation as contrasted with equivalence conservation using quantity and number conservation tasks. (Author/AJ)
