This study assessed the ability of third, fifth, and seventh graders to learn a problem-solving heuristic scheme and apply it to grade-appropriate tasks. A framework was utilized that focused on metacognitive aspects of task performance such as planfulness, strategy selection, monitoring, and evaluation. It was expected that use of the scheme…

This study examined the use of heuristic problem-solving strategies in math by seventh-graders under three different conditions: working individually; working in groups; and working as cooperative teams. No significant differences were found for the three conditions over a 5-week experimental period on a problem solving post-text (the Maryland…

This study investigated several aspects of a teaching experiment which focused on five seventh grade students' performance on nonroutine number theory problem-solving with a close look at the role of heuristics, concrete models, and the relationships between these variables. In the experiment, students were given a series of lessons on number…
