The purpose of the study was to examine the effect of a cognitive strategy programs on the
mathematical problem solving, participating act in solving the problem. The cognitive strategy
programs offered the students who have mild mental retardation at the grade 4, 5, 6 in
elementary school.
Using the multiple probe baseline across participants, I estimate the mathematical problem
solving and participating act in solving problem. The experiment includes the baseline, mediate,
contingency. During pre-sessions, the students solved the mathematical problem with their own
ways. In the main sessions, students learned strategies regarding how to solve the problem, how
to improve the problem solving strategy. Feedback was provided in order to help the
participants apply the strategies to real situations. The main goal of this study was to learn the
strategy of problem solving in mathematics and to improve the participating act.
The result is that, all of the students in the main session show the average 31% improvement
in mathematical problem solving, the average 11% improvement in participating act in solve the
problem. The program of this study revealed a significance of learning the cognitive strategy. It
was revealed that the training cognitive strategy was effective to solve the mathematical
problem. This study suggested that cognitive strategy increases the mathematic problem solving,participating act in solve problem.
