Although more than 15 years have passed since the introductory design courses were opened due to the introduction of engineering education certification in the civil engineering field, these courses have been operated somewhat unsatisfactorily compared to their importance as an introductory course for engineering design. This is partially because the quality of classes is affected by the instructor's individual ability due to the fact that a standard training plan for these courses has not been established so far. Therefore, in this paper, we try to present a reference model for the introductory design course by introducing a class operation case established through continuous improvement process over the last 10 years at Chungbuk National University. This case aims to cultivate students' problem solving and system design skills by carrying out projects to develop egg drop and wood bridge systems based on creative problem solving methodologies. As a result of a questionnaire survey conducted after the class, we found that students' problem solving and system design capabilities were improved significantly and there was a meaningful increase in level of interest and attention in civil engineering by taking this class.

The purpose of this study is to explore the possibility of changing students' learning styles and preferred teaching styles after applying the flipped learning method to engineering education. In order to achieve the purpose of this study, literature review and survey study were conducted. The subject of application of the flipped learning method is the 'Creative Problem Solving Methodology' class, which is one of the specialized liberal arts subjects operated for students of the college of engineering at D university in Gyeonggi-do. For the survey study, a tool adapted to the domestic conditions of Kolb's learning style test tool and Felder & Silverman's preferred teaching style test tool was used. In addition, pre- and post-tests were conducted to measure changes in the learning styles and preferred teaching styles. As a result of applying the flipped learning method for one semester, the learning style showed a tendency to change from an accommodative to a divergent learner. In addition, in the case of the preferred teaching styles, it was confirmed that there were statistically significant changes in the organization and the area of participation. Based on these findings, a proposal for a follow-up study was presented.

This study aims to elucidate the relationship between physics and mathematics to predict achievement for the college level of engineering courses. For the last 4 years, more than 3,000 engineering college freshmen of this study took the diagnostic tests on three subjects, which were physics, mathematics, and chemistry before enrollment. We studied how strongly these diagnostic scores can predict each general college course grades. The correlation between the physics diagnostic scores and the course grades in physics was .264, which was significantly lower than the correlation between the mathematics scores and the physics grades, .311. This stronger prediction of the mathematical diagnostic scores for the general course grades was not found when predicting the grades in chemistry. We therefore conclude that mathematical preparation can unexpectedly predict future achievement in physics better than physics preparation due to the academic interrelationships between mathematics and physics.

This study is aim to the effects of job satisfaction on the major satisfaction of science and engineering college students and also analyzed the mediating effects of future outlook of job and major relevance in career choice. To do this, structural equation modeling(SEM) and multi-group SEM were applied to data from 2016 Graduate Occupational Mobility Survey(GOMS). In the results of this study, the major satisfaction, future outlook of job and major relevance were positive effects on job satisfaction and the mediating effects of future outlook of job and major relevance were verified. And results of analysis according to gender difference, the coefficient of woman was smaller than man. Among major satisfaction had a positive effect on job satisfaction, job satisfaction fell for women who value their relevance to the major when choosing a job. Based on such results, universities need to further strengthen their role in helping them enhance their expertise through skills and learning about their majors.

This paper deals with the effects of teamwork competence on problem solving ability through the mediating effect of creative personality for the engineering students. For this purpose, a regression-based statistical mediation analysis has been performed for a simple mediation model in which teamwork competence and problem solving ability were treated as independent and dependent variables respectively, and creative personality was included as a mediation variable. The analysis results showed that the teamwork competence has direct effect on the problem solving ability as well as indirect effect through the creative personality. This result implies that the problem solving ability can be improved directly by improving the teamwork competence, and moreover, it can be further improved indirectly or through the mediation effect by improving the creative personality. Thus, in order to develop excellent problem solving ability, it is necessary to form team members in a balanced way between teamwork competence and creative personality in the team-based learning.
