The Development of Mathematics Ability in Word Problems Solving in the Topic of Interest and Value of Money by Using Polya's Problem Solving Process

Abstract

          This study “The Development of Mathematics Ability in Word Problems Solving in the Topic of Interest and Value of Money by Using Polya's Problem Solving Process” to study and develop Mathematics problem solving skills for learners. The objective of this research were 1) develop a learning management by using Polya's problem solving process on interest and value of money to be effective according to the 80/80 criteria. 2) to compare achievements on interest and value of money before and after learning management by using Polya's problem solving process. 3) to study student’s satisfaction on learning management by using Polya's problem solving process on interest and value of money. The sample were 30 students from Faculty of Business Administration majoring in Business Administration in Management of North Bangkok University, who enrolled in Mathematics and Statistics for Business subject in second semester of academic year 2021. The sample was simple random sampling. The research instrument were lesson plans by using Polya's problem solving process on interest and value of money, a test for measuring the learning achievement, problem solving ability test and a questionnaire on student satisfaction towards on learning management by using Polya's problem solving process. The statistics used for data analysis were the means of the percentage, mean, standard deviation, efficiency E₁/E₂ and t-test. The research results were as follows: 1) efficiency of learning management using Polya's problem solving process on interest and value of money E₁/E₂ was 81.83/80.17 2) learning achievement after the learning management by using Polya's problem solving process higher than before the learning management with statistical significance at the .01 level. 3) The mean of learners satisfaction with learning management by using Polya's problem solving process at a high level ( = 4.20, S.D. = 0.55).
