Identifies factors affecting problem solving strategies in the case of a multiplicative comparative situation involving three unknown quantities whose sum is known, and in which comparison relations between two pairs of the quantities are given. Proposes a model of the complexity of a word problem about such situation to analyze solution…

Explains an application of mathematical modeling within a school setting as well as progressive use of graphing calculators in mathematical modeling. Analyzes students' performances in the process of problem-solving using the problem of baton-passing in relay races. Discusses students' use of their mathematical knowledge and ideas when they used…

Teaching novice kayakers only the biomechanics of a roll and other "closed" (nonadaptable) skills does not create opportunities for flexible skill development. A wider approach teaches support strokes and rolls by focusing on "open" skills that can be transferred or adapted to any situation, including emergency decision making,…

Describes the Engineering Link Project for Year 11 students that might have an interest in engineering. It is a three-day course organized by teachers and conducted by engineers to give students the opportunity to test materials, design, construct, and try their own solutions to an engineering problem. (AIM)

Discusses a problem that appeared in the September, 1999 issue of this journal and presents solutions from students in grades 2-6. The question involved using colored cubes rearranged to make different stacked towers. (KHR)

Discusses examples of the detailed explanations that students offered in response to a written, open-ended geometry task, especially the ways in which students communicated their knowledge. Illustrates how different students may select different methods of communication such as using text, diagrams, or mathematical symbols to display their…

Discussion of how to teach students to use different environments for learning focuses on visual awareness and visual problem solving skills in a visual literacy walk. Highlights include observation techniques, multiple perspectives, categorizing and analyzing visual information, and generating multiple solutions for problem solving tasks. (six…

This review shows that mentally retarded children can produce problem-solving strategies if they comprehend the task requirements, share the experimenter's goal, and construct an optimal problem-solving representation. Instruction with multiple exemplars of a task can induce generalized strategy use, and nonvolitional mechanisms play a role in use…

Eighty-nine children, aged 4-8, generalized a problem-solving strategy learned on one task to a different version of the task. Compared to average-Intelligence Quotient children, the high-Intelligence Quotient children learned more from their illegal moves and more frequently recognized similarities in the tasks' features. (Author/JDD)

This study of 75 gifted students in grades 6-8 found that the group receiving Creative Problem Solving training with transfer strategies infused had a higher percentage of students applying the strategies to problems out of the context of the training sessions, compared to control group students and students receiving traditional training.…

This article discusses problem solving and how science educators can integrate problem solving into their instruction. The Search, Solve, Create, and Share (SSCS) model was developed based on the findings of problem solving research. (YP)

Twelve adolescents with learning disabilities were trained to use a cognitive strategy in algebra problem solving. The two-phase strategy (problem representation and problem solution) was effective in improving algebra performance on algebra word problems, and maintenance and transfer of the strategy were evident. (JDD)

Used a microgenetic method to examine knowledge acquisition as a process by coordinating existing theories with new evidence. Subjects were 17 community college students (ages 22-47) and 15 fourth graders. Assessed knowledge acquisition in problem solving in both physical and social domains. Found multiple strategies for, and varying levels of,…

Examined the nature of sociocognitive growth in 66 kindergarten and first-grade children by having pairs of children work together to solve spatial perspective-taking problems. Found that the entering performance composition of the dyads did not affect cognitive growth, whereas the construction of shared cognitive experiences in which children…

Discussion of computer conferencing as a collaborative learning strategy and a group-oriented decision-making process highlights a study of undergraduates at the University of Delaware who participated in a computer conference. Technical responsibilities, strategy development, debate advancement, and user temperament are examined; and the value of…
