| Abstract | The purposes of this research were 1) to compare the ability to solve problems on addition and subtraction before and after using Polya's problem solving process with the Bar model, 2) to compare the problem-solving ability after learning implementation with the 70% criterion, and 3) to study the satisfaction level of the students after learning implementation. The sample used in this research consisted of 24 Grade-4 students studying in the first semester of the academic year 2022 at Bankokwittayakhom School, who were selected by purposive sampling. The instruments were lesson plans, problem-solving ability tests, and satisfaction survey form. The statistics used to analyze the data were mean, percentage, standard deviation, and t-test. The findings revealed that the ability to solve mathematical problems after learning was greater than before learning, at a statistical significance level of .05. The ability to solve mathematical problems using the process was higher than the criterion of 70 percent. And the student's satisfaction after learning implementation through Polya's method with Bar model, was mostly in a high level (ar{x} = 4.50, S.D. = 0.45). |
