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…

The figural simplicity or salience of parallel lines was studied in 3- and 4-year-olds by means of a figural matching procedure where parallelism was a basis for judging similarity. (Author/JMB)

Though increasing complexity increased the difficulty of discrimination of form, nursery school, kindergarten, and first grade children were all above chance in performance, older children being superior. The results are discussed in relation to developmental perceptual theory. Portions of this paper were presented at the American Psychological…

In a study of spatial perspectives, third- and fifth-grade students were asked to coordinate perspectives on single-object and multiple-object arrays. (ST)

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)

Portions of this paper were read at the Eastern Psychological Association meeting, April 1968, Washington, D.C. (DR)

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…

The purpose of the study was to inquire into student learning of geometrical concepts, and the order and organization of those concepts relative to visual experience, while paying attention to their logical organization within the structure of mathematics. A test battery comprised of visual illusions, problems requiring interpretation of pictorial…

The objective of the investigation was to develop and test procedures for training children in coordination of projective space. (Projective concepts involve apparent distance, relative position, shape of figures, and other topological factors. A person with a command of projective space sees objects as a coordinated system of figures in space.) A…
