Children's worlds are increasingly populated by intelligent technologies. This has raised a number of questions about the ways in which technology can change children's ideas about important concepts, like what it means to be alive or smart. In this study, we examined the impact of experience with intelligent technologies on children's ideas about…

Two studies investigated the relationship between learning names and learning concepts in preschool children. More specifically, we focused on the relationship between learning the names and learning the intended functions of artifacts, given that the intended function of an artifact is generally thought to constitute core conceptual information…

Concept image and concept definition is an important construct in mathematics education. Its use, however, has been limited to cognitive studies. This article revisits concept image in the context of research on undergraduate students' understanding of the derivative which regards the context of learning as paramount. The literature, mainly on…

The authors explore how children's play can support the development of the foundations of mathematics learning and how adults can support children's representation of--and thus the "mathematization" of--their play. The authors review research about the amount and nature of mathematics found in the free play of children. They briefly…

We conducted a longitudinal analysis of the relative intensity and duration of interests associated with conceptual domains between the ages of 4 and 6 years, respectively. Results indicated a significant portion of preschool children do sustain an interest in conceptual domains during some portion of their childhood. Expected gender differences…

Barrett, Richert, and Driesenga [Barrett, J. L., Richert, R. A., & Driesenga, A. (2001). "God's beliefs versus mother's: The development of nonhuman agents concepts." "Child Development," 72(1), 50-65] have suggested that children are able to conceptualize the representational properties held by certain super-natural entities, such as God, before…

Contrary to the conventional view of infancy as a sensorimotor period without conceptual thought, research over the past 20 years has shown that preverbal infants are capable of at least 3 conceptual functions: forming concepts with which to interpret the world, recall of the past, and engaging in conceptual generalization. Research is described…

Two studies examined infants' understanding of spatial relations during the period following attainment of active search for hidden objects. (Author/SB)

Ninety-eight concepts from the Bracken Basic Concept Scale were paired, polarity (positive or negative) was assigned, and concept pairs were contrasted with 1,109 children ages three through seven to determine rate and sequence of polar concept acquisition. For 70 percent of the pairs the positive-pole concept was acquired before the negative-pole…

This study tested for deep understanding and critical thinking about basic quantum chemical concepts taught at 12th grade (age 17-18). Our aim was to achieve conceptual change in students. A quantitative study was conducted first (n = 125), and following this 23 selected students took part in semi-structured interviews either individually or in…

Recent research has shown that 2-year-olds fail at a task that ostensibly only requires the ability to understand that solid objects cannot pass through other solid objects. Two experiments were conducted in which 2- and 3-year-olds judged the stopping point of an object as it moved at varying speeds along a path and behind an occluder, stopping…

The developmental psychology of mathematical thinking and the clinical interview method can make major contributions to education by transforming the process of formative assessment--the attempt to use information concerning student performance, knowledge, learning potential, and motivation to inform instruction. The clinical interview is a…

Study indicates that for children, but not for adolescents, the number of concepts produced was inversely related to the level of abstractness of the stimuli. (Author/MG)

Three experiments involving 80 infants provide evidence that infants at 2.5 and 4 months represent objects and surfaces that they no longer perceive and that they operate on their representations to derive information about an event they have never perceived. Experiments suggest that cognition develops concurrently with perception and action. (SLD)
