There is an emerging consensus that spatial thinking is fundamental to later success in math and science. The goals of this study were to design and evaluate a novel test of three-dimensional (3D) mental rotation for 4- to 8-year-old children (N?=?165) that uses tangible 3D objects. Results revealed that the measure was both valid and reliable and…

Identifying and understanding the foundational skills children need to participate effectively in formal schooling is an important objective for research in early childhood education. One component of school readiness is cognitive self-regulation (CSR). The question this study addresses is how to assess CSR with prekindergarten-aged children in a…

This annotated bibliography attempts to answer the following questions: (1) What is criticial thinking? (2) Can it be taught and to whom? (3) Which methods are most practical for teaching critical thinking to secondary students? and (4) Can its acquisition be tested? The first question researches the literature for a definition of the term. The…

Analyzed the Weigl-Goldstein-Scheerer Color-Form Test using a sample of Danish children. Distinguished three dimensions: configuration of sorting, verbalization of the sorting principle, and the flexibility of switching sorting principle. The three dimensions proved themselves to constitute the a-priori-defined gradients. Results indicated a…

Investigated development of working memory in the transitional period from infancy to preschool years. The age-related increase in scores on the Imitation Sorting Task (IST) appeared to be about one unit every six months. Results suggest that the IST has a good construct validity. (AA)

Reviews bases for contemporary discontinuity theories of mental development, presents findings that support alternative proposition of continuity and scrutinizes assessment methods from which these continuity results derive. Also offers several models that help explain the continuity findings, and argues that individual differences in mental…

A study explored the relationship between print awareness and subsequent reading achievement in children. Specifically it measured changes in the development of print awareness across age and grade levels and across time, and compared the levels of lower-ability, educationally disadvantaged children in second and third grades to that of their…

The Springs task, an individually administered measure of ability to criticize and control experiments, is described. The task has characteristics similar to Inhelder and Piaget's Bending Rods task; it yields scores on naming variables, controlling variables, and analyzing experiments. (See also RIE: ED 163 092.)

Adolescents, ages 11-12 and 13-14, were tested for maturity of judgment about stability-change situations and about time perspective. (CP)
