The reasoning of adolescents in indeterminate situations was examined with particular attention given to how individuals incorporate the possibility that outcomes are determined jointly by more than one variable. Kuhn and Brannock's (1977) plant problem and two other similarly structured problems were administered to 25 inner-city adolescents…

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…

Examined the effect of mothers' familiarity with a formal operations task on performance and monitoring of a cognitive task with their children and on the child's later performance alone. The task-familiar mothers elicted higher level strategies during problem solving and allowed their children to participate more than did the other mothers; their…

This paper provides an introduction to the Alberta Education Developmental Framework, and describes the provincial department's position on curriculum and the cognitive domain. Intended for use in designing and implementing instruction, the developmental framework delineates the developmental stages and processes through which students progress,…

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)

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,…

Popular sentiment toward the teaching of thinking skills and, in particular, higher order skills, is on the rise. Many people are wondering about the best way for teachers to foster the growth of reasoning skills in their classrooms. This study attempts to improve the teaching of reasoning by investigating teaching behaviors or characteristics…
