Learning Activity Managemant on Pythagoras' Theorem Focused on Inductive and Deductive Reasoning for Mathayomsuksa II Student in Enrichment Science and Mathematics Classroom at Pramochwittayaramintra School Bangkok

Abstract

           The puroposes of this study were: to determine the level of achievement, reasoning ability and evaluate the attitudes of students toward learning activities on Pythagoras' theorem focused on inductive and deductive reasoning. The study was conducted during the first semester of the 2017 academic year with Mathayomsuksa II students at Pramochwittayaramintra School. The experimental group consisted of 26 students, selected through cluster random sampling. The students were taught for a total of 14 hours. The research instruments included: lesson plan, achievement test, reasoning test and attitude questionnaire. The statistics used in this study were: frequency, percent, arithmetic mean, standard deviation and paired t-test.

            The results indicated that; 1) The achievement of the experimental group after studying was higher than before studying at a .05 level of statistical significance and effectiveness Index (E.I.) was equal to 0.477; 2) The reasoning ability of the  experimental group was higher than 60% and effectiveness Index (E.I.) was equal to 0.596 and; 3) the scores on questionnaire showed a high satisfaction of the experimental group toward the instruction.
