THE DEVELOPMENT OF MATHEMATICAL CREATIVE THINKING SKILLS ON GEOMETRY TRANSFORMATION BY USING STEM EDUCATION

The purpose of this study was to study the development of mathematical creative thinking skills of students who have organizing learned by activities based on STEM Education. The research sample consisted of thirty Mathayom Suksa 2 students in Wat Tawan Ruang School and obtained by purposeful sampling. The research instruments used in this research were STEM Education leaning management plans in the topic of Geometry Transformation and a mathematical creative thinking test. The data were analyzed using mean, standard deviation, class normalized gain(g) and observation in the classroom by record from post-teaching.

The research finding; the post-learning mathematical creative thinking skills scores of students after learning under management based on STEM Education was significantly higher than their pre- learning counterpart scores. Class normalized gain equaled to 0.44, which was in the medium gain level. From observation students’ behavior found that the students expressed fluency thinking as clearly as possible which was consistent with quantitative data. In overall the students were able to express their mathematics creative thinking with four aspects.
