Studied children's transitive inference where representation of premises provided contradictory information depending on position of two elements in a A, B, C series. Eight-year olds did significantly better on the more complex problems than did six-year olds, suggesting the presence of a developmental sequence of algorithms that enable children…

Investigated were the relation between functional M-capacity and student performance in solving chemistry problems of increasing M-demand. Student performance decreased as the M-demand of the problems increased. (Author/YP)

Five- to six-year-old children estimated the size of Euclidian objects using an addition rule of Height plus Width, rather than a multiplying rule. Within the framework of information integration theory, tested whether intensive handling of objects would facilitate shift from addition rule to multiplication rule. Found that following handling,…

This study investigated preservice elementary teacher reasoning ability levels, science anxiety levels, and content achievement in a large midwestern university. Pretest and posttest measures were taken on three dependent variables: (1) reasoning ability (cognitive development); (2) science anxiety; and (3) science content achievement. In…
