The purpose of this study is to correlation analysis between technological problem-solving traits and engineering design competency. To this end, correlation analysis and regression analysis between technological problem-solving traits and engineering design competency were used to analyze the relationship between each other. To collect data on individual characteristics, technological problem-solving traits, and engineering design competency, a survey was conducted with university students. As a result of the analysis, there was no difference in engineering design competency by gender, but there was a difference in technological problem-solving traits. There was no difference in technological problem-solving traits by major, but there was a difference in engineering design competency. As a result of correlation analysis, the correlation was found. In the case of regression analysis, a statistically significant result was found in the problem-solving trait domain, and the regression analysis model was found to be suitable. The results of the analysis of differences in engineering design competency according to technological problem-solving traits showed that the effective problem solvers were significantly higher.

Amonng many creative problem-solving methodologies, the TRIZ with practicality and applicability has been utilized a lot in practice and education. This research introduced the TRIZ course for engineering problem-solving training to engineering college students. Then, a survey about students' ability to solve engineering problems after the TRIZ course were analyzed statistically. Finally, problem-solving cases of industry in each team project were examined. It is proved that an understanding of the TRIZ should be confirmed on that can be applied and utilized and can be linked to well performing team projects. Therefore, it is determined that more active efforts are required for the development of TRIZ learing methods to improve the education system to help students improve comprehension for students in creative problem-solving skills.

The core issue of ethical problem solving in engineering is to understand what exactly happened and to define its nature. Problems often arise mostly in morally complex situations. Traditional philosophical theories usually focus on extreme conflicts of interest and suggest moral theory-centered problem solving methods. However, these methods are not only difficult to specifically apply to real situations, but also are likely to fail to deal with actual moral issues in engineering fields. This study aims to develop more desirable ethical problem solving methods, based on STS (Science and Technology Studies) and engineering ethics combined. First, we have examined the engineering ethics with implications of an STS perspective, then have analyzed traditional ethical problem solving methods in a critical point of view. This study will suggest a new ethical problem solving method named Matrix Guide, based upon those analyses. Specifically, this study classifies four stages of problem definition, analysis, solving, and feedback. Here, we focus on how to combine technological and non-technological factors in each stage, when we are facing morally complex situations in engineering sectors.

Many methods have been suggested for a creative problem solving approach. TRIZ approach is ranked top in its practical application because it is originated from the real patent analysis. This approach is assumed to be generic which can be applied to any types of problems regardless of problem type and its domain. The objective of this study is to propose a creative problem solving approach using TRIZ's contradiction analysis, then introduce a case study of applying this approach to a creative design coursework. Main topic covers a creative problem solving approach, a problem definition using TRIZ contradiction analysis, finding invention principles, and problem solving from the generic approach. For the course project, Roborobo tool is adopted to implement the design concept. This coursework helps students finding a general problem solving approach, and applying a generic solution for their specific problem domain.

The purpose of this study is to analyze the characteristics of efficient problem-solving teams and inefficient problem-solving teams using SYMLOG. In this study, 35 college students majoring in engineering education at C university were organized into 7 teams and carried out technological problem solving projects over one semester. Based on the results of the team project, the top 2 teams were defined as efficient problem solving teams and the bottom 2 teams were defined as inefficient problem solving team, and analyzed the characteristics of the team using SYMLOG. The main results are as follows: First, an analysis of SYMLOG from efficient problem solving teams and inefficient problem solving teams showed that there was a difference between self-awareness and others' perception in terms of U(Upward)-D(Downward) dimension. Second, in the inefficient problem solving teams, there was a significant difference between self-awareness and others' in the F(Forward)-B(Backward) dimension. Third, there was no difference between self-awareness and others' in both efficient and inefficient teams at the P (Positive)-N(Negative) dimension. Fourth, an efficient problem-solving team had a clear leader, and there was a team member who supported the leader. On the other hand, the inefficient problem-solving team did not have a clear leader, or one person played the role of leader and there were no team members supporting the leader.

본 연구는 공대생들을 대상으로 창의적 문제해결유형별로 셀프리더십과 통제소재의 특성을 파악함으로써 문제해결능력과 과제수행을 증진시키고 효과적인 팀을 구성, 관리하는데 도움을 주기 위해 수행되었다. 창의적 문제해결유형의 3가지 차원(변화에 대한 지향, 일처리 방식, 의사결정의 중심)에 대해 각 차원을 구성하는 2가지 유형(혁신-개량, 외적처리-내적처리, 사람중심-과제중심)에 속하는 학생들을 분류하고, 문제해결유형과 성별에 따른 셀프리더십과 통제소재에 차이가 있는지를 알아보기 위해 이원분산분석을 실시했다. 문제해결유형의 주효과는 각 차원별로 다르게 나타났고, 성별의 주효과 및 성별과 문제해결 유형의 상호작용효과는 모든 척도에서 나타나지 않았다. 마지막으로 본 연구의 제한점과 후속연구를 위한 제언이 논의되었다.

The creative problem-solving becomes one of the most important cognitive skills in the engineering education. As AI and automation technology(of 4th Industrial Revolution) penetrate our everyday life, its role as a human ability is highlighted. In this paper, we examine the relation between the creative problem-solving and the critical thinking, and the usefulness of the latter in the engineering education. To sum up, the critical thinking is the pre-conditon of the creative problem-solving.

In this paper, the effect of daily creativity of engineering students on problem-solving ability is addressed through the dual mediating effect of teamwork competency and self-directed learning ability. To this end, a regression-based statistical mediation analysis has been performed on the dual mediation model in which daily creativity and problem solving ability were treated as independent and dependent variables respectively, and teamwork competence and self-directed learning ability were included as mediation variables. The analysis result confirmed that the daily creativity has direct effect on the problem-solving ability, as well as indirect effects through teamwork competence and self-directed learning ability. In particular, the serial mediating effect of teamwork competency and self-directed learning ability was also confirmed to be statistically significant in the relationship between daily creativity and problem-solving ability. This verifies that problem-solving ability can be improved not only directly by improving daily creativity but also indirectly by improving teamwork competence and self-directed learning ability. In addition, teamwork competency showed greater indirect effect on problem-solving ability than self-directed learning ability, so increasing teamwork competency has a more significant effect on improving problem-solving ability than increasing self-directed learning ability. Therefore, in order to develop better problem-solving ability, it is necessary to identify and improve the learners' teamwork competency first and to strive to create an environment where learners can solve problems based on mutual trust with their teammates.
