3D 모델링을 활용한 발명교육 프로그램이 초등학생의 기술적 창의성과 흥미도에 미치는 효과

Abstract

The purpose of this study was to develop an invention education program using 3D modeling based on solving invention problems. And to prove the effectiveness of the developed invention education program, it is to verify the effect of elementary school students' technological creativity and interest change. To achieve this aim, a 3D modeling invention education program was developed using the procedure in the ADDIE model. The developed program was finally completed after verification by a group of experts. The selected subject for the 3D modeling invention education program was “Production of inventions that can hold writing instruments.” A 10-hour program was organized, and a teaching plan was prepared for each session in addition to class materials. To examine the effect of the program, a paired-sample t-test was conducted, which indicated a significant difference in technological creativity. In the sub-domain of technological creativity, there was a significant difference in task obsession and curiosity. The students created 3D drawings using Tinkercad for their concept drawings. Because the experiential activity of directly observing the 3D expression of the conception was developed, the will to express one's own until the end was developed, which exhibited an effect on task obsession. In addition, it was judged that curiosity about 3D drawing production programs and inventions increased during the process of expressing the results. The paired-sample t-test was also used to investigate the effect of the program on the interest level of elementary school students, where a significant difference was revealed. During the program, it was judged that interest in invention and 3D drawing production increased through the process of sharing and exchanging opinions and, presenting and evaluating their own work and the work of others.
