The Development of Mathematical Problem-Solving Ability by using Deductive Learning with GeoGebra Program on Preliminary Data Analysis Topic for Matthayomsuksa 6 Students

Abstract

The objective of this research was to develop mathematical problem solving of Mathayomsuksa 6 students who learned through deductive learning management integrated with the GeoGebra program on Preliminary data analysis topic to meet the criterion of 60 percent. The target group used in this research obtained by purposive sampling that selected from 30 students in Mathayomsuksa 6/6 at Borabue Witthayakhan school, Borabue district, MahaSarakham province, the Office of Secondary Education Service Area Office 26, in the second semester of the 2019 academic year. The instruments used in this research were 11 deductive learning management plans integrated with the GeoGebra program, the evaluation form for ability to solve mathematical problem, and the behavior observation form for mathematical problems solving. The statistics used for data analysis were mean, percentage, and standard deviation. The research findings revealed that students had 76.50 % of mathematical problem-solving ability in the first operating cycle and showed 78.83 and 81.58 in the second and third operating cycles. The research results showed that the deductive learning management integrated with the GeoGebra program by using the concepts of Polya in the first and second operating cycle and using KWDL technique in the third operating cycle. This was a learning activity arrangement which focuses on the development of mathematical problems by using problems in daily life or problems near students to analyze problems and solve problems together. The teacher has duty to propose various situations that will motivate the students to pay attention. Along with giving theories and principles for problem solving that can improve mathematical problem solving of MathayomSuksa 6 students. The results of the research were in accordance with the objectives. Students have developed the ability to solve mathematical problems and passed score of 60 percent for 28 people, representing 93.33 percent.
