DEVELOPMENT OF LEARNING ACTIVITIES BASED ON POLYA’S PROBLEM SOLVING PROCESS TO ENHANCE MATHEMATICS PROBLEM SOLVING ABILITY ON LINEAR EQUATIONS WITH ONE VARIABLE OF MATTHAYOMSUKSA 1 STUDENTS

Abstract

The purposes of this research were to develop learning activities model based on Polya’s problem solving process and to compare the learning achievement and the ability of mathematical problems solving through linear equations with one variable by using Polya’s problem solving process of Matthayomsuksa 1 students between students who learned by learning activities model based on Polya’s problem solving process with a normal learning. The samples were 77 students of Matthayomsuksa 1 in the second semester of academic year 2020 at Thantongpittayakom school, Buriram province, gained by cluster random sampling. The instruments were Polya’s problem solving process lesson plans, normal lesson plans, the 20 items of multiple-choice mathematics learning achievement test that reliability was 0.91, and the 5 subject tests of the ability to solve mathematical problems that reliability was 0.93. The statistics were analyzed by percentage, mean, standard deviation, and z - test independent sample.

          The results of the research were a developed the learning activities model based on Polya’s problem solving proces of Matthayomsuksa 1 students had the efficiency 82.26/79.74. The learning achievement and the ability of mathematical problems solving through linear equations with one variable of Matthayomsuksa 1 students who learned by learning activities model based on Polya’s problem solving process were higher than normal learning students at the .05 level of significance.
