Developing the Ability to Solve Mathematical Problems in Analytic Geometry & Conic Section by Using Deductive Learning Activities in Conjunction with the Geogebra Program for Mathayom 4 Students

Abstract

            This research aims to 1) develop learning activities using deductive learning activities combined with the Geogebra program, achieving efficiency according to the criteria (70/70); 2) compare students' problem-solving abilities in mathematics using deductive learning activities combined with the Geogebra program against the 70% criterion; 3) examine students' satisfaction with learning using deductive learning activities combined with the Geogebra program. The research sample consisted of 40 students from Grade 10 in the second semester of the 2023 academic year at Khwa Rai School, under the Secondary Education Service Area Office of Mahasarakham, selected by cluster random sampling. The research tools included 12 learning activity plans, which were found to be of very high quality. Additionally, a 5-item mathematics problem-solving ability test and a 5-point Likert scale satisfaction survey developed by the researcher were used. Statistical analyses included mean, percentage, standard deviation, and one-sample t-test. The findings revealed that the efficiency of the deductive learning activity plans combined with the Geogebra program was 74.71/73.38, which was higher than the set criterion of 70/70. Students' problem-solving abilities were significantly higher than the 70% criterion at a statistical significance level of .05. Overall, students' satisfaction with learning using deductive learning activities combined with the Geogebra program was at the highest level ( = 4.87, S.D. = 0.28).
