Development of Mathematics Learning Activities using Deductive Learning and Polya’s Concept with GeoGebra Program to Promote Problem Solving Abilities on Parallel Lines for Mathayomsuksa 2 Students

Abstract

The purposes of this study were: (1) to develop learning activities using Deductive Learning and Polya’s Concept with GeoGebra on Parallel Lines to meet the efficiency criterion of 75/75. (2) to find the Effectiveness Index of learning through Parallel Lines in mathematics using Deductive Learning and Polya’s Concept with GeoGebra Program. (3) to compare the mathematical achievement and problem-solving ability of students who after learning through used Deductive Learning and Polya’s Concept with GeoGebra Program on Parallel Lines to 75 percent of criteria. The participants in this study were twenty-seven students who studied in Grade 8 in the second semester of academic 2023 at school in Mahasarakham province. However, they were selected by using cluster random sampling. The research instruments were (1) mathematics learning activities using Deductive Learning and Polya’s Concept with GeoGebra Program on Parallel Lines plan (2) the learning achievement test (3) the mathematical problem-solving ability test. The statistics for data analysis are percentage, mean, and standard deviation. Moreover, to examine the hypothesis by using a Hotelling’s T². The results of the study were as follows: (1) The Efficiency lesson plans for the organization of mathematics learning activities using Deductive Learning and Polya’s Concept with GeoGebra Program on Parallel Lines was 85.29/80.99, respectively. (2) The effectiveness index of plans for organizing mathematics learning activities using Deductive Learning and Polya’s Concept with GeoGebra Program on Parallel Lines 0.6974, respectively. (3) Mathematical achievement and mathematical problem-solving ability of students who studied cooperative learning using Deductive Learning and Polya’s Concept with GeoGebra Program on Parallel Lines is higher than the 75 percent threshold  at .01 level of significance.
