The purpose of this study is to explore the design direction of artificial intelligence convergence liberal arts subjects based on flip learning and maker education through analysis of learner needs in a non-face-to-face classroom environment caused by COVID-19. To this end, we analyzed the priorities of subject content elements by using the Borich needs assessment and The Locus for Focus model along with students' perceptions of flip learning for students who took and did not take maker education-based liberal arts courses. Based on this, it was used as basic data for designing the curriculum. The study results are as follows. First, the content elements of the artificial intelligence liberal arts curriculum based on maker education consisted of a total of 9 areas and were designed as a class using flip learning. Second, the areas with the highest demand for education are 'Artificial Intelligence Theory', 'Artificial Intelligence Programming Practice', 'Physical Computing Theory', 'Physical Computing Practice', followed by 'Convergence Project', '3D Printing Theory', '3D Printing practice' was decided. Third, most of the questionnaires regarding the application of flip learning in maker education-based artificial intelligence liberal arts subjects showed positive responses regardless of whether they took the course, and the satisfaction of the students was very high. Based on this, an artificial intelligence-based convergence liberal arts curriculum using flip learning and maker education was designed. This is meaningful in that it provides an opportunity to cultivate artificial intelligence literacy for college students by preparing the foundation for artificial intelligence convergence education in liberal arts education by reflecting the needs of students.

In this study, interviews are held with the faculties of two elementary schools on narrow sites located in Seoul to examine the existing problems of the elementary school on narrow site and the need for the new facilities of the elementary school on narrow site in order to derive the implications for the planning guidelines of such school construction. As a result of the survey, it was found that the substitutes of the playground installed in the elementary school on narrow site were not suitable for physical play activities, physical education class activities, and other curriculum operations. In order to secure an adequate physical activity an space for elementary schools, faculty members were demanding that the entire floor or rooftop of the school building be spatialized for physical activities. Additionally, problems such as noise generation and the lack of special rooms and public space were occurring in the elementary schools on narrow sites and are being deteriorated by accommodating an over number of students, and therefore policies are required to ensure that the appropriate number of students are maintained in the case of the schools on narrow sites.

The purpose of this study is to develop middle school English classes using Problem-Based Learning(PBL) based on flipped learning and to examine its effects. Recently, various attempts to combine flipped learning and PBL have been made; however, many studies have not been applied to middle and high school curriculums yet. The attempt of this study is expected to have theoretical and practical significance. The instructional model was derived from the review of previous studies, and the development of instructional program followed the general design procedure(analysis-design-development-implement-evaluation), and its validity was secured with the advice of related experts. To verify the effectiveness of the program, the English academic achievement test and the English key competency test were conducted before and after the program. Changes in English academic achievement were analyzed by the paired-sample t-test, and the effect of key competency and the level of achievement test performance (high vs, low) on the pre-post score change was analyzed by the mixed effects repeated measures ANOVA. As a result of the analysis, both academic achievement and key competencies increased, and the low-level students in the pre-academic achievement test showed more improvements. In conclusion, the PBL class based on flipped learning is effective in improving the English academic achievement and key competencies of middle school students, and in particular, it is shown to be an effective teaching method for students with low academic achievement.

This study attempted to investigate the effects of experience of non-contact lectures on learning flow against college students majoring in cosmetology and provide basic data to beauty education industry in the with-COVID-19 era. For this, a self-administered questionnaire survey was performed against 300 college students majoring in cosmetology from June 7 to 21, 2022. A total of 286 copies were collected and used for final analysis. The collected data were analyzed by frequency analysis, factor analysis, exploratory factor analysis, descriptive statistics, correlation analysis and multiple regression analysis, using SPSS 21.0, and the results found the followings: According to analysis of non-contact lecture experience factors, two course satisfaction factors were obtained. In learning flow, learning pleasure and learning flow were found. Specifically, class activities had a positive influence on 'learning pleasure (𝛽=.279, p<.007)' and 'learning flow (𝛽=.221, p<.031)' with statistical significance (p<.05). In addition, course satisfaction revealed a positive effect on 'learning flow (𝛽=.223, p<.041)' with statistical significance (p<.05). The above results confirm that experience of non-contact lectures affects learning flow. Therefore, it is anticipated that there would be more efforts to seek an efficient non-contact learning plan in this new era.

The aim of this study was to develop a comprehensive home economics teaching-learning plan, following the stages of analysis, design, development, and evaluation. The focus was on the 2015 revised home economics curriculum, specifically the 'prevention of sexual violence,' to enhance students' digital literacy competencies. In the analysis stage, the necessity of developing digital literacy competencies was confirmed by analyzing the 2022 revised national curriculum. Extracting elements from the 2015 revised home economics curriculum and textbooks, a digital tool utilization plan was designed in the subsequent design stage, aligning with learning goals, content composition, and digital literacy competency for each class. The development stage involved creating teaching-learning materials and digital tools for six sessions, centered around the topic of 'prevention of sexual violence.' In the evaluation stage, six content experts assessed the teaching-learning plans using a 5-point Likert scale and open-ended questions. The validity evaluation confirmed the effectiveness of the teaching-learning plans in improving middle school students' digital literacy competencies. Based on feedback from the experts, the plans for the six sessions were revised, with an additional session added, resulting in a total of seven sessions. It is envisioned that the home economics teaching and learning plans developed in this study can be implemented in home economics classes to foster students' digital literacy capabilities.

The purpose of this study is to propose implications by analyzing the textiles and clothing curriculum of vocational high schools. Literature and data were analyzed, surveys and FGI were conducted, and the following research results were derived. First, many schools chose 'Basic dress design' or 'Basic dress composition' as basic subjects. Through this, it was confirmed that technical training for practice is a priority for vocational schools, and that more discussion is needed regarding the lack of theoretical subjects. Second, similarly to the basic subjects, practical subjects offered are concentrated on 2 to 3 subjects. The teachers asserted that some subjects such as 'Knit apparel production' and the 'Leather and fur design production', which require a lot of equipment and advanced technology, cannot be offered without support from the government. Third, the NCS competency unit of the practical subjects is easy to proceed with the class or is closely concentrated on the type of manpower training presented by each department. Fourth, this study proposes that for technical education to expand students' choice, it is necessary to cultivate teachers competencies linked to the industry. The results of this study are expected to provide basic data on the organization of the next textiles and clothing professional curriculum and help understand vocational education at vocational high schools. In addition, it is believed that this study will contribute to developing and settling various subjects when the high school credit system is implemented by expanding students' choice of major-related subjects.

The goal of this study was to improve environmental awareness by systematically developing a hands-on online lesson for adults on making drink bags by upcycling discarded umbrella cloth. The lesson was developed using an ADDIE model. During the analysis stage, the instructional design direction was established based on the findings of previous studies. In the design stage, the operation of practical classes in the online environment was specifically planned. The contents of education and the training time were also determined. The materials developed during the development stage included a kit and theoretical information containing images to raise awareness of environmental pollution and the significance of upcycling, as well as videos and photos. During the implementation stage, two sessions were held three months apart. A total of 36 adults participated, with 18 participants in each session. In the evaluation stage, the first session participants provided feedback on class satisfaction, which led to improvements. Positive feedbacks were received from the second session participants, who expressed satisfaction with the smooth communication and easy approaches to the learning materials. In both instances, the surveys on environmental consciousness and attitudes yielded an overall average score of 4.27, indicating a generally positive evaluation.

This research was carried out experiments with changing processes and design parameters to optimally design a SiC-based 1200V power MOSFET, and then, essential electrical characteristics were derived. In order to secure the excellence of the trench gate type SiC power MOSFET device to be designed, electrical characteristics were derived by designing it under conditions such as planner gate SiC power MOSFET, and it was compared with the trench gate type SiC power MOSFET device. As a result of the comparative analysis, the on-resistance while maintaining the yield voltage was 1,840mΩ, for planner gate power MOSFET and to 40mΩ for trench gate power MOSFET, respectively, indicating characteristics more than 40 times better. It was judged that excellent results were derived because the temperature resistance directly affects energy efficiency. It is predicted that the devices optimized through this experiment can sufficiently replace the IGBT devices generally used in 1200V class, and that since the SiC devices are wide band gap devices, they will be widely used to apply semiconductors for vehicles using devices with excellent thermal characteristics.

This study aims to investigate the disparity between the teacher's perception of student-centered inquiry classes and the actual implementation of such practices. Specifically, we compared an elementary science teacher's self-perception of her science lessons with the observers' evaluation using the Reformed Teaching Observation Protocol (RTOP) of the "Temperature and Heat" unit. Research data were collected through classroom teaching survey, interview, and science lessons video which were analyzed using the RTOP. As a result of the study, the teacher recognized that she was practicing inquiry-oriented/student-centered classes, but the results judged by the RTOP score were found to be transitional/student-affected classes by a slight difference. Teacher H planned and practiced classes based on a high understanding and content knowledge of the curriculum and created a science classroom culture that promotes active interaction among students as well as students and teachers. However, teacher-led aspects were still emphasized in teaching design and implementation, and the project theme and content were inappropriate to improve the quality of students' science inquiry experience. In the end, the slight difference between teacher's perception of inquiry-oriented/student-centered classes and actual implementation is related to how student-centered "lesson design" is and how to plan and implement classes supported by "procedural knowledge" for students' experience in the science inquiry process. These results indicate that the teacher's self-evaluation alone is not enough to determine whether the teacher's intentions and efforts are actually being implemented, and that it is necessary to conduct objective analysis, evaluation, and discuss the results of science classes by the external observers.
