Development of Mathematics Learning Activities Base on Polya’s Method with Geogebra Program to Enhance Mathematical Problem Solving on Rectangles for Prathomsuksa 4 Students

Abstract

The purposes of this research were to; 1) develop the Mathematics learning activities by using Polya’s Method with GeoGebra program entitled triangle for Prathomsuksa 4 students as the criteria at 75/75 level; 2) compare the students’ achievement test results with the research criteria; 3) compare the students’ problem solving with the research criteria; and 4) study the students’ retention after learning with the model. The sample consisted of 15 Prathomsuksa 4 students, Buamas (Buamas Choosin) School, second semester, academic year of 2021.  The sample used the cluster random sampling. The research instruments were: The Polya’s teaching method with Geogebra programs lesson plans, the 20 items, 3 items of mathematical problem solving ability writing test, and 4 multiple choices achievement test. The statistics used percentage, means, standard deviation, and t-test. The results of the research were as follows; 1) the efficiency of the developed learning model were as 81.80/78.67, which as similar as the research criteria at 75/75; 2) the students’ achievement scores was also as the research criterion as 75 percents; 3) The students’ Mathematical problem solving skill were higher than the research criteria, which statistically significant at the .05 level; and 4) the result of the sample’ achievement scores after learning with the model and later 2 weeks were similar.
