A STUDY OF MATHEMATICS LEARNING ACHIEVEMENT AND GEOMETRIC THINKING ON CIRCULAR OF MATHAYOMSUKSA 3 STUDENTS LEARNING BY USING THE GEOMETER ‘S SKETCHPAD PROGRAM (GSP) WITH CONCEPT OF FLIPPED CLASSROOM ACTIVITIES

Abstract

The objectives of study were to 1) compare academic achievement of Mathayomsuksa 3 students who were taught by teaching using the Geometer’s Sketchpad Program (GSP) with concept of Flipped Classroom activities with 70 percent standardize criterion 2) compare academic achievement of them before and after learning 3) study levels of Geometric Thinking based on the Van Hiele Model by using the Geometer’s Sketchpad Program (GSP) with concept of Flipped Classroom activities before and after learning. The subjects of this study were 32 Mathayomsuksa 3 students of Taweethapisek School, Bangkok Yai District, Bangkok, during the first semester of 2018 academic year. The students were randomly selected by using the cluster random sampling.The instruments in data collection consisted of achievement test, geometric thinking level test. The one group Pretest-Posttest design was used for this study. The data were statistically analyzed by using t-test one-group and t-test for dependent samples. The results of study revealed that 1) Academic achievement of students had achieved 60 percent standardize criterion statistically at the .05 level of significance. 2) Students had academic achievement statistically higher than before the experiment at the .05 level of significance. 3) The students had most increasing levels of Geometric thinking based on the Van Hiele Model at level 2 and level 3
