In this study, we examined the cases of online video classes conducted under the COVID-19 situation for 46 first-year students majoring in electrical engineering at a 3-year college in Gyeongnam. The research was carried out according to the course development process so that classes could be conducted efficiently, focusing on electromagnetism(1) course in the second semester of the first year. The online class consisted of uploading PPT recorded videos and lecture materials to the LMS and giving assignments. The contents of the study were in the scope of examining learners' perceptions through online learning contents, assignment submission, mutual feedback between instructors and learners, university-level lecture evaluation, and free opinions on online video-based electromagnetism(1) classes. As a result of the study, it was confirmed that online lecture review and problem-solving are particularly important for understanding lecture materials, and also given the nature of engineering subjects that require plenty of mathematical expressions, the detailed and immediate feedback provided by instructor enhances learners' class satisfaction and understanding. Based on these, the direction of online classes to be developed after the COVID-19 pandemic and teaching and learning methods suitable for the characteristics of subjects were discussed.

This study explored the determinants of first job employment outcomes(employment status, salary, company size) of engineering college graduates using 2018 Graduates Occupational Mobility Survey(GOMS) data. Independent variables were used as variables for personal characteristics, academic background, and job preparation efforts. The priorities and interactions between the factors determining employment outcomes were identified using the decision tree analysis. The research results are as follows. First, it was found that the most important factor in determining the 'first job employment status' was 'exam preparation(public and private company, test for teacher recruitment)' among individual's job preparation efforts. Second, the most important factor in determining 'first job salary' was 'gender' among individual characteristics. Third, the most important factor in determining the 'first company size' was the experience of 'corporate job aptitude study' among individual's job preparation efforts. Based on the results of the analysis, suggestions for establishing customized career development strategies for engineering college students were presented.

This study started from a critical review of the current problem of ethics education in engineering colleges, how it has become stereotyped and perfunctory and hence, is failing to properly foster engineers with a sense of responsibility. Existing engineering ethics education occupies a very limited role and weight in the periphery of the engineering curriculum, unable to hold a central position. This situation is of grave concern, especially when the leadership of engineers with social and professional responsibility is of great importance. Therefore, this study explored new directions and strategies for engineering ethics education while reviewing domestic and foreign studies dealing with the current status and problems of engineering ethics education. First, this study discussed the need for and direction of shifting to ethical engineering education instead of ethics education centered on liberal arts courses. Second, this study presented specific practical strategies to construct the ethical engineering curriculum. For example, it is necessary to establish the ethical engineering curriculum with an education linking ethics with human development goals, ethics education using Korea's current issues and agendas, micro- and macro-level analysis related to engineering, and leadership education.

In this paper, the characteristics of peer-evaluation and self-evaluation of team activity participation in project-based learning and their usability were investigated. The characteristics of peer-evaluation and self-evaluation are as follows. First, in peer-evaluation and self-evaluation of project-based learning, the correlation between the two evaluation scores was very high. When students' scores from their peers correlate very well with the scores they give themselves, it means that they apply the same criteria to their peers and to themselves when evaluating team activity. Second, there was no difference in peer-evaluation and self-evaluation scores between groups with different written test scores. The fact that peer-evaluation and self-evaluation scores do not change according to academic ability shows that the two evaluation areas are independent. Third, the self-evaluation score in project-based learning is statistically significantly higher than the score received from peers. This raises doubts about the fairness of self-evaluation. Therefore, in this paper, it is suggested that self-evaluation of team activities in project-based learning is carried out together with peer-evaluation, but only peer-evaluation is reflected in credits.

The purpose of this study is to design and operate non-face-to-face online practice class in engineering education, and to explore students' perceptions and effectiveness of them. To this end, after developing and implementing a strategy for non-face-to-face online practice activities in the 'Introduction to Electric Circuits and Lab' course, the questionnaire responses of 47 learners were analyzed, and the group differences were investigated using Kruskal-Wallis test. As a result, it was found that students' perceptions of non-face-to-face online practice class were positive in terms of learning effect, learning convenience, interaction, and satisfaction. The group difference according to the face-to-face/non-face-to-face preference method was found to be higher in the group that preferred non-face-to-face class in terms of learning convenience, interaction and satisfaction. As for the group difference according to the number of questions and answers of the learners, the group who answered the question showed a higher awareness of the learning convenience and interaction than the group that did not. In addition, implications for designing a learning environment for non-face-to-face online practice classes were presented.

Generative AI has arrived and it's here. Education, research, industry, and labor are all on edge about the changes it will bring. It is noteworthy that while there is a wide range of optimistic and pessimistic predictions about the impact of generative AI, there is more concern than hope when it comes to education. This paper focuses on the lack of discussion on the impact of AI in higher education. First, we reviewed the process of the emergence of generative AI and introduced how the impact of AI is being understood from various perspectives. Second, we classified work areas based on expertise and efficiency and analyzed the impact of AI on work in each area. Finally, the study found that the educational perception of generative AI and the way it is perceived for engineering education purposes can be very different. It also argued that there is a lack of active discussion and debate on areas that need to be specifically discussed around generative AI. This has led to a phenomenon known as professors' delayed indifference. We emphasized that it is time for a serious and realistic discussion on the connection and integration of AI and education.

In engineering education, stimulating students' questions and encouraging learning participation are crucial for achieving higher-order thinking abilities. This study aims to investigate the use and effect of an online communication channel in fostering engineering students' questioning abilities. Consequently, in this research, we gauged students' satisfaction with an engineering class that implemented a communication channel, and scrutinized the changes in their perceptions regarding the significance of questions, their engagement in learning, and their academic self-efficacy. In addition, we interviewed the students who participated in the class. The outcomes are as follows: Firstly, student satisfaction improved compared to the previous semester's class where the communication channel was not utilized. Secondly, learners' understanding of the importance of asking questions positively escalated, alongside their actual frequency of posing questions. Thirdly, there was an improvement in learners' active engagement in their studies and their academic self-confidence. The findings of this research suggest that communication channels should be employed to motivate learners to pose questions and involve students in effective learning.
