We conducted a qualitative research of case studies based on think-aloud protocols. The aim was to carry out in-depth analyse secondary students' cognitive difficulties appearing in early stages of transfer processes in problem-solving. The task was to relate several source problems to a target problem, in order to solve it effectively. Source and…

This paper reports the findings of research into an educational intervention featuring open-ended mathematical problems situated in "real life" contexts and associated pedagogies. "Money and financial mathematics" is the topic in focus, with tasks termed "financial dilemmas" being trialled by 35 teachers in 16…

In order to achieve their course learning outcomes, public affairs instructors can train students to solve real community problems (SRCP). This approach focuses on the learners themselves and aims to transform the role of college professors from traditional teaching (lecturing) to facilitating and coaching students' learning activities. This study…

The Tower of London (TOL) task has been widely used in both clinical and research realms. In the current study, 104 healthy participants attempted all possible moderate- to high-difficulty TOL problems in order to determine: (1) optimal measures of problem solving performance, (2) problem characteristics, other than the minimum moves necessary to…

Discussion of the role of small group performance focuses on solving problems to improve performance. Types of tasks and their effects on groups are described; group resources are discussed; factors affecting group process are explained; and a flowchart for solving group performance problems is presented.

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally…

The efficiency of infants' actions was observed as they picked up and used food-laden spoons that varied in orientation. Two interventions were designed to facilitate efficient action beyond when infants were presented with one spoon in alternating orientations: one spoon was presented in the same orientation for several consecutive trials to help…

A study of the physical activity or motor responses associated with curiosity, persistence, and problem solving behaviors was undertaken to learn more about the general developmental nature of these behaviors among elementary school children. The sample consisted of 125 children from kindergarten, second, fourth and sixth grade, all of whom…

This study examined the relationship between children's gender-typed conversational styles and joint problem-solving performance. Sixty preschool children between 4 and 5 1/2 years completed three problems with a same-sex or opposite-sex peer. Two structured tasks, copying a Tinkertoy model and stringing beads; and one unstructured task, building…

Two experiments related structure of a task to underlying cognitive mechanisms. Found that 3-year olds were no better at predicting behavior from partially true beliefs than from entirely false beliefs. Three- and 4-year olds, and autistic children had distinct performance profiles across tasks. Concluded that conceptual foundations for a…

It has been suggested that cognitive style interacts with performance on tasks measuring formal thought. It is hypothesized that cognitive style interacts with task context rather than with the underlying formal thought processes. Experiments are reported to clarify the type of task that elicits an interaction and to determine whether such…

A study involving 110 fifth- and sixth-graders (51 male and 59 female), classified as low or high in effort orientation, assessed the effects of task- versus performance-oriented instructions on a computer-assisted test programed to ensure that all examinees failed to solve all problems. Problem-solving strategy analyses were preformed. (TJH)
