A Study on Mathematics Learning Achievement Using Polya’s Problem-solving Process: Addition and Subtraction of Decimals for Grade 4 Students at the Demonstration School of Rajabhat Maha Sarakham University

Abstract

This research aims to 1) Investigate the mathematics learning achievement of Grade 4 students at the Demonstration School of Rajabhat Maha Sarakham University using Polya’s problem-solving process on the topic of addition and subtraction of decimals. 2) Compare the pre-learning and post-learning computational skills of Grade 4 students using Polya’s problem-solving process on the topic of addition and subtraction of decimals. And 3) Examine the satisfaction of Grade 4 students with learning through Polya’s problem-solving process on the topic of addition and subtraction of decimals The results of this study indicated that students’ computational skills in addition and subtraction of decimals improved after learning through Polya’s problem-solving process. The average post-test score was 16.46, equivalent to 82.30%, while the average pre-test score was 7.75, equivalent to 38.75%. Furthermore, students who learned through Polya’s problem-solving process demonstrated a high level of satisfaction, with an average satisfaction score of 4.31 and a standard deviation of 0.74 Therefore, the use of Polya’s problem-solving process in learning effectively enhanced students' computational abilities.
