These prompts were designed to help students organize and reflect upon their problem-solving processes.This study analyzed the effectiveness of PlanIt! as a problem-solving tool. Subjects were administered a pretest to assess their initial ability to solve multi-step, algebraic word problems. Subjects were randomly assigned to experimental and control groups. The control group used an abbreviated word processing version of PlanIt! During the treatment period, subjects were administered an alternate form of the pretest problems. Additional information collected included the amount of time spent on the treatment task and, for the experimental subjects, the number of PlanIt! prompts answered. The following week, an algebraic posttest was administered to assess whether any portion of PlanIt!'s solving heuristic had been remembered. In the final session, a second posttest, an open-ended problem different from the previous tasks, was administered to assess whether the PlanIt! heuristic would transfer to a novel problem type.Analyses of variance were performed to analyze group differences for the dependent variables. There were significant differences between the experimental and control groups on treatment test scores and time on treatment task. The experimental group spent significantly more time on the treatment test using PlanIt!, but the control group scored significantly higher on the treatment test. There were no significant differences between experimental and control groups on pretest or either posttest. The regression analysis revealed that for the experimental group, time on task and prescore were ... |
