In this study, 3D-image based course material has been suggested as a potential pedagogical tool for laboratory courses for aviational maintenance in vocational high schools. With a special focus on assembly/disassembly of the combustion chamber, 3D contents described here are created by Soildworks 2014 based on the textbook widely used in aviational high schools. By analyzing several textbooks currently adopted at various schools, we have clearly shown that the current text-based teaching method is far from being effective regarding providing adequate learning environment for high school students who study aviational maintenance. From the analysis of the conventional textbooks, it is seen that it is urgent that we should come up with more effective and efficient way of teaching methods for these topics at vocational high schools. Using Solidworks, we have developed very vivid 3D image-based course material for topics related to a combustion chamber in the airplane. Newly developed 3D material is seen to clearly show step by step procedures of assembly and disassembly of the combustion chamber which has crucial importance in the aviational laboratory courses. Especially the transparent feature in Solidworks could make it possible to observe the parts covered by outer casing, which can not be seen even in any laboratory class with real objects. 3D animated views could provided unprecedented learning environment for students to acquire core knowledge with ease for the maintenance of a combustion chamber. In order to provide easy access for students to this 3D-based course material, the exclusive viewer is also developed using MS office powerpoint 2007. An example of a learning plan using 3d course material is suggested as well.

In this study, we have investigated potential application of 3D model-based learning material in training of new workers for production of electrical systems in the ship-building. Most of new trainees such as new employees or workers on job-transition have lots of difficulty when given the first task due to their poor ability to understand related engineering drawings. This is mainly caused by the fact that drawings are loaded with too many ambiguous symbols to precisely describe the characteristics of components required for installation of electrical equipments and cables. As one way to improve the ability of new employees to read drawings, we have suggested a new training method based on 3D models of major components required for production of the electrical systems in the ship.

Currently, most of content restoration using artificial intelligence learning is 2D learning. However, 3D form of artificial intelligence learning is in an incomplete state due to the disadvantage of requiring a lot of computation and learning speed from the existing 2 axes (X, Y) to 3 axes (X, Y, Z). The purpose of this paper is to secure a data-set for artificial intelligence learning by analyzing and 3D modeling the stone pagodas of ourinari by era based on the two-dimensional information (image) of cultural assets. In addition, we analyzed the differences and characteristics of towers in each era in Korea, and proposed a feature modeling method suitable for artificial intelligence learning. Restoration of cultural properties relies on a variety of materials, expert techniques and historical archives. By recording and managing the information necessary for the restoration of cultural properties through this study, it is expected that it will be used as an important documentary heritage for restoring and maintaining Korean traditional pagodas in the future.

This paper describes the human body learning system using the multi-modal user interface. Through our learning system, students can study about human anatomy interactively. The existing learning methods use the one-way materials like images, text and movies. But we propose the new learning system that includes 3D organ surface models, haptic interface and the hierarchical data structure of human organs to serve enhanced learning that utilizes sensorimotor skills.

Advances in computer technology have made it possible for educators to design and develop their own multimedia instructional materials using visuals such as animation. Although, it generally believed that the Mew attribute of computer animation facilitates student's foaming, there is still relatively little research regarding the way in which student benefit from multimedia instruction using 3-D animation. The purpose of this research was to examine and determine whether the use of 3-D computer generated images is an effective teaching device for hoping children to understand color theory, and enhancing the tractional methods. In this study, a 3-D computer generated presentation was creative and it demonstrated the mixing of primary color to obtain secondary color. Three research hypotheses were developed in this research. The first hypothesis stated that 3-D computer generated presentation will be an effective device for teaching color theory. The second was that the presentation will be eye-catching and it will hold the children's attention. The third was presentation would enhance the children's memory of color. Results of this study show that visualization technology and the use of 3-D graphics ends can be employed in the field of art education to increases a chi1d's understanding of color theory. Also, it was proved that teaching children through 3-D graphic is an highly effective teaching tool. Thus this research is a oontribution to both children's au education and the relatively new field of computer animation.

We explored the method of teaching and learning of 3D based software which is useful for 3D content's authoring and utilization as a suitable tool of teaching and learning for 'Smart Learning' environments. To investigate the possibility of application in the field, we applied this software to 'Smart School' temporally. After that, we conducted a survey of learning satisfaction of students, and assessed the possibility of application in the field via one-on-one talk with teachers. As a result, we drew a positive conclusion for the applications, which are instructional medias in various subject areas, presenting materials for motivation, a tool for individual or cooperative presentation, and instructional medias for underachieving students or gifted students.

천문학은 시간적·공간적 규모가 크기 때문에 학습자의 수준에 따라 공감과 이해의 정도에 차이가 크다. 2015 개정 과학과 교육과정에 따르면 초등학교 5학년부터 태양계에 대한 내용을 다루고 있다. 하지만 이를 설명하기 위한 교과서의 사진과 동영상 자료는 태양계를 명확하게 전달하기 어렵다. 이에 대한 대안으로 3D Modeling을 통한 체험 교육을 제안한다. 천문학 교과에서 3D Modeling의 적용은 학생들의 흥미, 태도의 향상 등 교육적 효과의 상승으로 이어진다. 이에 본 연구에서는 3D Modeling의 도구 중 3D 프린터와 레이저 절단기를 이용해 융합교육(STEAM) 프로그램을 개발하고 학생들에게 적용하여 창의적 문제해결능력에 미치는 영향을 알아보고자 한다. 초등학교 교육과정에 제시된 태양계 관련 학습자료를 분석하였고, 융합교육(STEAM)에서 제안하는 상황제시, 창의적 설계, 감성적 체험의 교육단계 중 '창의적 설계' 단계에 3D 프린터와 레이저 절단기를 통해 개발한 kit를 이용하여 융합교육(STEAM) 프로그램에 적용하였다. 개발된 프로그램을 형식 교육의 장에 적용하여 개발된 평가지표를 토대로 사전·사후 평가를 실시한다. 향후 3D Modeling을 초등학교 교육과정뿐만 아니라 중·고등학교 교육과정 또한 분석하여 적용한다면, 천문대중화를 위해 큰 도움이 될 수 있을 것으로 사료된다.

The purpose of this study was to develop a digital textbook on 'structure and contraction mechanism of skeletal muscle' with the learning model for biomimicry-based convergence. The unit of 'structure and contraction mechanism of skeletal muscle' is a part of Life Science I in high school. The convergence learning model was designed with three phases of biomimicry-based convergence (Exploration-Design-Implementation) including 3D modeling & printing. The developed digital textbook was composed of 8 sessions which contains the following learning contents : Exploration of skeletal muscle, creative designing of skeletal muscle using sketch application and 3D modeling, convergent implementing of the designed using 3D printing, exploration of muscle contraction, creative designing of muscle contraction using sketch application and 3D modeling, and convergent implementing of the designed using 3D printing. Each session is also involved in the contents of gallery widgets, media widgets, keynote widgets, sketch widgets, the cloud, polling widgets, and review widgets for interactive and mobile learning. After administering the developed digital textbook to 20 high school students, it was shown a positive effectiveness on life science learning for high school students. Moreover, the digital textbook was evaluated as to promote student's abilities on creative designs and implementation related to biomimicry-based convergence. The digital textbook was also shown a favorable response on students' interest and self-directed learning on life science.
