In this research, it was intended to determine the effects of geometrical-mechanical intelligence game activities on the spatial abilities of secondary school seventh grade students. The research was designed according to quasi-experimental design with pre-test and post-test control groups and conducted with two experimental and two control…

The purpose of this study is to analyse geometric transformations of children in the early childhood period. The study utilised a case study to design one of the qualitative research methods. Interviews were conducted with 6-, 7- and 8-year-old children, in total 24 children, who were enrolled in a private pre-school and a primary school of the…

This study aims to examine the developmental changes in young children's perception. A matching completion task consisting of three geometric figures and one bird-like figure were completed by children 3-5 years of age ("N" = 99). The rotation effect, in which the correct response decreased with orientation (45°, 90° 135°, and 180°), was…

In this article, the author draws on contemporary science to illuminate the relationship between early play experiences, processes of self-development, and the later emergence of the fractal self. She argues that orientation within social space is a primary function of early play and developmentally a two-step process. With other people and with…

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…

In this examination of young children's acquisition of geometric skills, spatial performances were conceptualized as specific combinations of actions applied within stimulus contexts. The relationships among eight action/context combinations were examined, and predicted patterns compared with observed ones. (Author/BW)

Used realistic models of turning situations to study second, fourth, and sixth graders' concepts of turning and bending. Found that young students viewed turning (knob, doll, and door) as a movement, and bending (road bends) as a configuration. Many did not spontaneously interpret turning as a configuration or bending as a movement. Explored…

Seven-year-olds compared successively presented oblique lines which varied as to their position within a square display and their relation to the diagonal axis of the display. Children apparently encoded lines in terms of position and axis features. They used a categorical spatial representational system to compare oblique lines. (Author/RD)

The investigation reported pursued the possibility of cross-cultural differences between American and Swiss children in terms of how they perceive and conceptualize spatial figures. There was statistical evidence that the preferences of American and Swiss children were different when compared as a whole or by sex and test version. (MK)

A developmental sequence of stages in the representation of regular space figures, first obtained in Jamaica, was cross-validated on a U.S. sample. Discussion centers on the relation between representational ability and perceptual development and on the variation in the difficulty of drawing different figures. (Author/MK)

Tests seven- , 10- , and 13-year-olds for developmental differences in processes and strategies involved in geometric matrix solution and the relationship between strategy differences and item complexity. (AS)
