The results of a survey on 6,192 elementary schools across the country in April 2019 are as follows : First, there was a correlation between the number of students and the number of classes. Second, 2,788 schools (45.0%) were small schools, 1,931 schools (31.2%) were suitably sized schools, and 1,473 schools (23.8%) were large schools among the 6,192 elementary schools surveyed. Third, there was a significant difference in the proportion of small schools, suitably sized schools, and large schools by province. Among the 8 metropolitan cities, Seoul had the lowest percentage of small schools at 9.8%, followed by Incheon at 18.0%. Among the 9 provinces, Gyeonggi Province had the lowest rate at 26.8%, while Jeollanam-do had the highest rate at 87.2%. This means that adopting the same standard for abolition of small schools throughout different provinces can cause serious problems. Therefore, it is necessary to reflect the educational conditions of each province.

The purpose of this study is to recognize kindergarten teachers' experiences of child violence for identifying the site's needs for the implementation of preventive education in early childhood and to provide basic data on child violence. To this end, nine teachers were interviewed in-depth. From the study results, first, child violence-related child behavior, which usually occurs in kindergartens, includes physical assault, aggression, verbal violence, threats and threats, and bullying. Second, teachers usually use direct intervention laws in cases of child violence, but were finding it difficult to intervene properly with many tasks or high teacher-to-child ratios. Teachers recognized the need for lower teacher-to-child ratios and placement of each class burden. Third, teachers were aware of the need for prevention education for child violence targeting infants, and instigated the following appropriate interactions immediately after problem behavior occurred: large group activities, specific multimedia education data and parent education. Fourth, teachers are concerned about the possibility of problem behavior being learned and imitated through education in the implementation of prevention education for children's violence. Therefore, this study proposed the need to develop various teaching methods that could be applied to infant education sites, focusing on the types of child violence-related problem behaviors that occur in kindergartens.

This study analyzed the awareness and actual condition on metaverse utilization in education for design major students. An online survey was conducted for 14 days from May 10 to 23, 2023, targeting 120 students majoring in design at D University. The evaluation method of the questionnaire was a nominal scale and a 5-point scale, and the questionnaire results were analyzed through SPSS 29.0. First, it is necessary to sufficiently share the advantages of metaverse utilization in education with students, and to provide basic literacy programs utilizing the characteristics of metaverse and supporting class activities. Second, students' response will be higher in studio classes where practical training is conducted rather than information delivery or understanding-oriented lectures. Third, in order for the metaverse to become a means of education in the digital transformation era rather than just a temporarily medium in COVID-19 era, specific and systematic design education programs reflecting the characteristics of the metaverse need to be continuously developed. In addition, it is important for instructors to actively review the use of the metaverse and search for various ways to utilize it.

It is difficult to improve maritime safety in the aspect of human elements without seafarers' job satisfaction. Therefore, through the career development for seafarers from their entries into the job to their retirements, longer and more stable seafarers' life on board ship could be achieved together with maritime safety. This study aims at the establishment of seafarers' career path model and the verification of six hypotheses by using the questionnaire data of 2,830 respondents of students, slip officers and shore-based ex-seafarers. The results of analyses of behavior factors on the career path are as follows; first, it is important to improve educational environment and to provide seafarers with detailed information on seafarer's life; second, economic factors such as income-level and etc. do not play a role in promoting motivation of going to sea; third, the guidance to shore jobs at proper time increases seafarers' job satisfaction and induces longer stay at sea; last, it is necessary to simplify the licence system for seafarers, to allow seafarers to acquire higher class certificates, and to work at higher rank on board ships as early as possible.

This study intends to investigate the features and the difference between traditional instruction and flipped learning through a comparative analysis of verbal interaction on those learning method. The videos of traditional instruction and flipped learning of 5th graders social class were recorded and transcribed, which were analyzed in Flanders verbal interaction model. The results were as follows: First, the flipped learning is composed of students' learning activity and a teacher's statement properly, while the traditional instruction consists of a teacher's statement mostly. Second, the traditional instruction tends to be directive classes that full of dominant, despotic, restrictive communication of teacher oriented. In contrast, the flipped learning is inclined to be nondirective with integrated, democratic, comprehensive, permissive communication of students oriented. Third, the flipped learning emphasizes students' activities and statement and reduces delivery of knowledge, meanwhile, the traditional instruction stresses delivery of content that the teacher centrally located. Lastly, the type of verbal interaction in traditional instruction is a one-way communication, students responding simply in teacher's lectures and questions. On the other hand, in flipped learning lessons, more interactive communication occurs, teachers complimenting students and accepting their comments.

The purposes of this study were to develop a scientific inquiry-based STEAM education program and to investigate its effect on changing middle school students' self-efficacy in science, job awareness, and attitudes toward STEM. A scientific inquiry-based STEAM program was developed with the theme of 'earthquakes', using the ADBA model, which was taking up the total of six class periods. The final program, which had been revised and completed after being pre-tested with middle school students, was implemented to 105 third-graders of middle school in a metropolitan city. One sample pre-post paired t-test before and after applying the program to the same group was conducted, and its effectiveness was analyzed in terms of self-efficacy in science, job awareness, attitudes toward science, technology, engineering and mathematics. Results showed that the STEAM program on the theme of 'earthquakes' demonstrated its effect on improving the students' of self-efficacy in science subject and their awareness of science-related jobs. Furthermore, this program indicated a statistical significance in improving middle school students' attitudes, awareness, and abilities, values, and continuing interest towards science, technology, engineering, and mathematics. Therefore, we suggest that this scientific inquiry based STEAM program be used to help students to improve their scientific investigation skills as well as their creative and integrated thinking abilities in schools.
