IT education in the colleges or universities and IT industry in producing IT manpower are urgently called for to balance its supply and demand. To correct this problem, Ministry of Information and Communication launched a program where demand-oriented curriculums are developed and applied to colleges. This paper proposes a design technique based on meta-model and software development process in developing curriculums and courses. This meta-modeling technique is proven to result in the extendibility, flexibility and quality improvement in software design. Therefore, we expect that proposed technique makes it possible to be improved in quality.

This study proposes a new educational approach to basic engineering education using reverse-engineering. A freshmen level engineering coursework provided by the University, 'Engineering Design', is to deliver the understanding of the general relationship between their major and its adjacent engineering fields. Students are to understand the identity of their major fields through this effort. There are some limitations, however, to achieving these educational objectives by providing lectures in a classroom environment or practical experience because of the broad nature of the subject. A new educational approach on 'Engineering Design' has been implemented for past five years to achieve this goal using reverse-engineering techniques and this paper describes it in detail.

Circuit theory is a systematic study that analyzes and designs the most basic circuits in the field of electrical and electronic engineering. Circuit theory courses are organized as major courses for one or two semesters in the second year of university, so that electrical and electronic engineering students must learn. Experimental courses are being together organized for students to enhance understanding of circuit theory and cultivate the skills and the abilities of circuit design through experiments with actual circuits. This paper is a case study on the teaching method applied in electric circuit design and experiment courses to enhance the learning effect on the experimental education that supports circuit theory. To do this, we propose a 15-week instructional model consisting of theory study, simulation, experiments, and design projects. In the proposed model, the simulation and preliminary experiment preparation process are reinforced to complement the theoretical concept and the design project is introduced to acquire practical circuit design skills as engineers. The results of five-year operation demonstrate the effectiveness of the proposed model.

The purpose of this study was to investigate the effects of engineering design-based ocean cleanup classes on STEAM attitudes and creative engineering problem-solving dispositions. Furthermore, during this process, we tried to determine interesting points that students encountered in engineering design-based classes. For this study, a science class with six lessons based on engineering design was developed and reviewed by a professor who majored in engineering design, along with five engineering design experts with a master's degree or higher. The subject of the class was selected as the design and implementation of scientific and engineering measures to reduce marine pollution based on the method implemented in an actual Ocean Clean-up Project. The engineering design process utilized the engineering design model presented by NGSS (2013), and was configured to experience redesign through the optimization process. To verify effectiveness, the STEAM attitude questionnaire developed by Park et al. (2019) and the creative engineering problemsolving propensity test tool developed by Kang and Nam (2016) were used. A pre and post t-test was used for statistical analysis for the effectiveness test. In addition, the contents of interesting points experienced by the learners were transcribed after receiving descriptive responses, and were analyzed and visualized through degree centrality analysis. Results confirmed that engineering design in science classes had a positive effect on both STEAM attitude and creative engineering problem-solving disposition (p< .05). In addition, as a result of unstructured data analysis, science and engineering knowledge, engineering experience, and cooperation and collaboration appeared as factors in which learners were interested in learning, confirming that engineering experience was the main factor.

A digital signage is constructed using a speech recognition based API, and VRSM (Voice Recognition Smart Mirror) that obtains information such as weather, map, exercise information, schedule, and image by user's voice command so as to be different from other commercialized products is proposed. This course provides an effective method of engineering education through the process of being evaluated as the result of independent graduation certification system, and also it had been the opportunity to design and produce works for 3 semesters by 2 students one group in the majors. Through the comprehensive capstone design, it has experienced engineering approach and creative thinking opportunity. We have won the best academic prize by participating in the academic conferences of the institute about the interim result, and obtained the results of the prize contest in other academic conferences. The improvement in practical skills obtained through this process proved to be beneficial for self-confidence and job-seeking opportunities through actual employment.

The purpose of this study is to analysis the recognition of engineering professionals in Primary and middle school education. For the study, survey was proceeded through experts in engineering. The result of research follows. First, experts in engineering recognized that engineering has a significant impact in the national economic development and competitiveness. Experts in engineering, had a recognition consistent to some extent for engineering. and we have found engineering's own characteristics that emphasize "problem solving and design, innovation and creativity, economy optimization". Second, experts in engineering recognized that engineering education in Primary and middle school rarely take place, and also does not provide enough information for students. Third, experts in engineering recognized that engineering education is very needed in Primary and middle school. Through this, students can understand creative design problem-solving process. In addition, Experts of engineering, have a variety of educational demands for School level to the level of engineering education should start, level educational purposes, how to apply effective and so on.

This study is intend to define learning driving force for learner-centered education and to derive it's components(IDEA : degree of Interest, Dynamics of learning process, degree of self-Effectiveness, expectation level of Academic achievement). To validate the concept of driving force, we analyzed the instructional design techniques, operating procedures, result reports, professor's comments of flipped learning courses which were conducted systematically in K-university during last 4years. As a result, I suggest the directives and guidances required for effective flipped learning based on driving force.

In this study, the newly designed course related to creative problem solving is introduced. According to the characteristics of multimedia engineering, the Alice, which is well known as an effective 3D interactive authoring tool, is adopted as the supporting tool to validate the accomplishment of study goals set up for software design. Each creative problem solving phase could be clearly implemented and its expected performance could be evaluated efficiently by using Alice. The result of curricular implementation and performance evaluation is shown.
