Tessellation is included in many mathematics curricula as one way of developing spatial ideas. If students do not understand tessellation in the intended ways, however, the development of other spatial ideas, such as properties of shapes and symmetry, may be compromised. Van Hiele levels were used as a basis for analysing the descriptions of eight…

This book has as its major focus the comprehensive assessment of children's early numerical knowledge and strategies and their advancement. Practical and theoretical aspects of assessment are explained in detail. A major feature of the book is a learning framework in early number that is applied in analyzing the results of assessment and planning…

This book introduces students to the types of problems and processes used throughout the "Reshaping Mathematics for Understanding" series. The problems in this unit deepen students' understanding of mathematics by encouraging them to clarify concepts and challenge their own assumptions. Additionally, by providing opportunities to give and follow…

Space perception is necessary for work in branches of technology from the machine industry to civil, electrical, and material engineering. The spatial perception of students coming to technical universities is not highly developed. There are several reasons for this unfortunate situation: firstly, the lack of emphasis put on geometry and other…

This paper presents a collection of thoughts and observations about a grand theory of creativity in the arts. The theory elaborated in the paper is based upon the following five major bodies of psychological knowledge and research: (1) hemisphere differences and cerebral lateralization; (2) chemical balance in the brain and bipolar factors; (3)…

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

Replicates a study of spatial egocentrism in Thai 5- to 7-year-old children, using a sample of 4- to 8-year-old Australian children. (Author/CM)

In two experiments, undergraduates did/did not create a maplike representation while learning a passage, and were either forced to study the map, instructed to study, or given no map prior to reading. Free-recall data showed that forced map study benefited learners with low vocabulary scores. (Author/GK)

Used two spatial and language tasks to investigate that clockwise directionality in circle drawing indicates neutral integration difficulties. Tasks were administered to 106 children, eight years of age. Data were analyzed for sex differences and circling behavior. None of the hypotheses based on Blau's theory was supported. (Author)

Indicates that spatial ability describes a variety of different behaviors and briefly reviews efforts to define intelligence factors and identify processes involved in solving tasks requiring spatial ability. (DS)

Analysis of 116 students revealed those who preferred to process mathematical information by verbal-logical means outperformed more visual students on tests. Spatial ability and knowledge of spatial conventions had less influence on performance than expected. (MP)

First-, fifth-, and eighth-grade children were asked to make bearing and distance estimates to six targets from three sighting locations in their school. Among the results, correlations between estimated and actual bearings and distances were extremely high at all grade levels. Bearing accuracy increased between first and fifth grades. (Author/RH)

Children's performances in pointing a telescope at landmarks surrounding their own neighborhood were assessed for 60 children in three age groups: first and second graders, fourth and fifth graders, and seventh and eighth graders. Among the results, sex differences both in point consistency and in the accuracy of pointings from imagined reference…

A modified viewer rotation procedure was used to contrast two possible explanations of spatial egocentrism in spatial perspective tasks. Subjects were 60 children in first, third, and fifth grades. (MP)

A battery of four tasks which measure the interhemispheric transfer of information was utilized to test the hypothesis that there will be an increase in efficiency of interhemispheric transfer with increasing age. (MP)
