3D 프린터를 활용한 기술교과 교육 프로그램 개발 및 적용 – ‘제조 기술과 자동화’ 단원을 중심으로

Abstract

The purpose of this study was to develop the technology education program with 3D printer focused on the ‘Manufacturing Technology and Automation’ in the middle school technology subject. The education program was implemented by following the 4 stages of preparation, development, implementation, and evaluation. The preparation stage was composed of the analysis of ‘Manufacturing Technology and Automation’ unit and the selection of themes. The development stages was made up of the establishing educational objectives, the selection of learning content, the preparation of the theme net, and the organization of learning content. And the development program was put into practice for the students in the implementation stage. In the evaluation stage, the program was revised and supplemented by the evaluations obtained from the specialists and students. The results of this study were as follows. First, the preliminary themes of the technology education program with 3D printer were selected pencil stand, strap of mobile phone, and stamp. Through the consultation of experts, the theme of education was chosen to make pencil stand. Second, the learning contents of making pencil stand were composed of conception and design stage of concept sketches and 3D modelling, printing stage of converting the file for 3D printing, and evaluation stage of the output finishing and presentation of activity. Third, the validity assessment of the education program with 3D printer was conducted by experts group. And the developed program was evaluated by students through preliminary lesson and field application. Through these activity, the final program was developed.
