THE DEVELOPMENT OF LEARNING ACTIVITY PACKAGE USING PROBLEM SOLVING PROCESSES OF POLYA WITH BAR MODEL DRAWING TECHNIQUE ON FRACTIONS TO PROMOTE SOLVING MATH PROBLEM ABILITY FOR PRIMARY 5 STUDENTS

Abstract

The objectives of this research are to develop a learning activities package using Polya's problem-solving processes and the bar model drawing technique on fractions for primary 5 students, ensuring its effectiveness based on the 80/80 criteria. Additionally, the study aims to compare the students' ability to solve math problems before and after using the learning activities package, and to compare the learning achievement before and after using the learning activities package. The sample group used was the primary 5 students at Watthapsai School, Pongnamron District, Chanthaburi Province, selected for multi-step random sampling, consisting of 1 classroom with 30 students. The research instruments were a learning activities package using Polya's problem-solving processes with the bar model drawing technique on fractions for primary 5 students, along with a math problem-solving ability test and a learning achievement test on fractions. The statistics used for analyzing the collected data were percentage, mean, standard deviation (SD), and t-test.

               The results revealed that the learning activities package, which used Polya's problem-solving processes and the bar model drawing technique to solve math problems for primary 5 students, had an efficiency of 83.23/81.11, surpassing the 80/80 criteria. Moreover, the students who learned with the learning activity package demonstrated higher post-learning math problem-solving abilities than pre-learning abilities, with statistical significance at the.05 level. Additionally, the students who learned with the learning activity package had post-learning achievement higher than pre-learning achievement, with statistical significance at the .05 level.
