First-, third-, fifth-, and sixth-grade children were administered 20 relational reasoning problems in which they had to deduce the possible sizes of one item relative to two others on the basis of a visual comparison and a written clue. Dramatic differences were observed between fifth- and sixth-grade children. Corrective feedback improved…

In two studies, children participated in route-planning tasks in which they were asked to find the shortest path to retrieve certain items. In Study 1, children participated in two versions of the task (standard versus feedback) differing in the amount of contextual support. Forty-eight children, ages 6, 8, and 10 years, had to help their…

Using a balance-beam task, studied 48 preschoolers to elucidate the process of knowledge construction from the emergence of new representation to transformed problem solving. Analyses revealed a multifaceted development from the first signs of weight representation to fully elaborated weight-based problem solving. Case studies of five children…

Focused on (1) the effect of mother-child interaction during a problem-solving task on subsequent, independent child performance; and (2) the variability in the division of task responsibilities and maternal regulation of the child as a function of task difficulty, child age, and task component. Participants were 60 three to five year olds and…

This study, which assessed hypothesis-testing abilities using a discrimination-learning paradigm, found that 16 language-impaired primary-level children solved fewer problems than 16 controls equated on cognitive level, but the 2 groups used similar hypothesis types to solve the problems. Type of verbal feedback (explicit versus nonexplicit) did…

Reports a study to determine if the formal capabilities of 81 elementary education preservice teachers would be enhoused from problem solving instruction with manipulative feedback or with pictorial feedback. Results indicate the manipulative mode was clearly superior in student attitudinal responses and achievement. (SL)

This paper briefly reports on a series of studies that explore the relationship between symbolic or pretend modes of reasoning and cognitive processes which underlie conservation of quantity. It is hypothesized that the mental transformations which the child makes while playing a game of make-believe, namely, the transformation from his original…

This article presents a rationale for emphasizing discovery instruction over guided instruction in teaching cane travel skills to people with severe visual impairments. Discovery instruction is seen to facilitate the use of intrinsic feedback in developing perceptual-cognitive skills as well as promoting problem solving, retention, and transfer of…

To replicate the findings of a previous experiment in which it was shown that the systematic presentation of rules and feedback on conservation and conservation-related problems can be employed to teach young children the traditional (Piagetian) liquid quantity problem rapidly, an analysis was made of the role of two others variables: (1) use of…

In recent research, sequences of hypotheses observed during problem-solving have been categorized according to six hypothesis sampling systems that vary in efficiency. Three systems were characterized as strategies (focus, dimension check, hypothesis check) because they always lead eventually to solution. The remainder were called stereotypes…

Performance data for 42 subjects pertaining to seven course objectives and ten propositional logic tasks were analyzed for hierarchical relationships using ordering theoretic technique. The resulting hierarchy indicated that simple implication and particular contraposition propositional logic tasks were prerequisite to some course objectives. This…

The concept of self-regulation--the process whereby students activate and sustain behaviors and cognitive paths which are systematically oriented toward attainment of learning goals--is increasing in importance among educators. Self-regulation includes activities such as attending to instruction; organizing, coding, and rehearsing information;…

The developmental increase in the ability to solve problems is a puzzle. Does it come from basic changes in mental skills, or is it a matter of practice? This book from the Developing Child series synthesizes recent research examining children's problem-solving skills development. Chapter 1 presents the major themes: (1) there is increasing…
