3D 프린터를 활용한 나무 모형 프랙탈 구조 제작 STEAM 프로그램 개발 및 적용 효과

Abstract

Recent educational use of 3D printers can do mutual cooperation among students as well as advance the big thinking and creativity. So far, what is to consider about the programs studied, it needs to select activity-oriented and subject-oriented learning content but not only do printing with 3D printer for entertainment. It also requires to develop STEAM educational materials to actively participate in. The purpose of this study is to investigate the effect of 3D printer STEAM program on the science process skills, creative problem-solving ability and scientific attitude of elementary school students. For this purpose, the STEAM program was developed based on the STEAM education standard consisting of the situation presentation, the creative design, and the emotional experience so that the 3D printer and the fractal structure can be learned in a convergent manner and applied to the sixth grade students of elementary school. Study subjects had no experience for training of 3D printer or STEAM class. As a result, the creative problem-solving ability and scientific attitude of the group applying the program showed a significant improvement in the post-test than the pre-test. However, the science process skills are no significant difference between the post-test and the pre-test. So it needs to be further complemented the contents of the STEAM program for improvement of the science process skills. This means that the STEAM program using 3D printer developed in consideration of the characteristics of elementary students positively influenced the creative problem-solving ability and scientific attitude of elementary school students. In future, the STEAM programs on the theme of fractal structure and 3D printer need to be developed more variously. And it seems necessary to apply it to the elementary school field.
