The The Development of Mathematics Learning Activities on Addition and Subtraction of Counts Greater Than 100,000 by Using Problem-Based Learning Supplemented with Polya Problem Solving Process of Prathomsueksa 4 Students

Abstract

The purposes of this research were: 1) to develop mathematics learning activities on addition and subtraction of counts greater than 100,000 using problem-based learning supplemented with POLYA problem solving process of Prathomsuksa 4 students,  2) to study mathematics problem solving ability of counts greater than 100,000 using problem-based learning supplemented with POLYA problem solving process of Prathomsuksa 4 students, and  3) to compare students’ mathematics achievement of Prathomsuksa 4 students before and after being taught by problem-based learning supplemented with POLYA problem solving process.

             The sample group consisted of 37 Prathomsuksa 4 students in a regular program at Udon Thani Rajabhat University Demonstration School, Mueang, Udon Thani Province, in the first semester of Academic year 2023. The research instruments were divided into three parts: 1) 9 lesson plans, Mathematics learning activities on addition and subtraction of counts greater than 100,000 using problem-based learning supplemented with POLYA problem solving process, 2) teachers’ and students’ learning behavior observation forms observed by the research assistant. The interview questions at the end of the process operated by the researcher and the researcher assistant, and the practice cycle tests, 3) A Mathematical problem solving ability test and a mathematics achievement tests. This research was divided into three operating cycles learning activities: first cycle was lesson plans 1-3, second cycle was lesson plans 4-6 and third cycle was lesson plans 7-9. All instruments were employed to analyze the data at the end of the process.

The findings for this research were as follows: 1. Developing of mathematics learning activity on addition and subtraction of counts greater than 100,000 using problem-based learning supplemented with POLYA problem solving process can be revealed in six steps:1) determined problem, 2) understand the problem, 3) study 4) knowledge synthesize, 5) summarize and assessment of the result, and 6) presentation and performance evaluation by POLYA problem solving process.2.The students’ mathematics learning scores on addition and subtraction of counts greater than 100,000 toward teaching problem-based learning supplemented with POLYA problem solving process were 32 points as 80% which were not less than 75%, and 3. The students’ pretest and posttest scores on addition and subtraction of counts greater than 100,000 toward teaching problem-based learning supplemented with POLYA problem solving process were 10 points as 50% and 16 points as 81% respectively.  The students’ posttest score on POLYA problem solving process was higher than the pretest.
