  • BACKGROUND/OBJECTIVES: To encourage schools to transform school meal programs to be more educational, it is necessary to evaluate the related environment using a whole school approach. We developed a school food culture evaluation tool to quantitatively evaluate school food culture in Gyeonggi Province, Korea. SUBJECTS/METHODS: Based on a literature review, a school food culture evaluation system consisting of areas, subareas, indicators, and questions (scored on a 5-point scale) was constructed. The validity of the tool was reviewed using focus group interviews, the Delphi technique, and a preliminary survey. Subsequently, evaluation tool was applied to elementary, middle, and high schools in Gyeonggi Province. Data from 115 schools were used for the final analysis. This included 64 elementary schools, 29 middle schools, and 22 high schools. At least one respondent from each group-school administrators, teachers, and nutrition teachers (or dietitians)-participated. The results were compared at the school level. RESULTS: The evaluation tool consisted of 66 questions in 5 areas (institutional environment, physical environment, educational environment, educational governance, and school meal quality). The total average score for school food culture was 3.83 points (elementary school 3.89 points, middle school 3.76 points, and high school 3.76 points) and did not differ significantly among school levels. Among the 5 evaluation areas, scores were highest for institutional environment (4.43 points) and lowest for physical environment (3.07 points). Scores for educational environment, educational governance, and school meal quality were 3.86, 3.85, and 3.97 points, respectively. CONCLUSION: It is necessary to improve the physical environment to create a desirable school food culture in Gyeonggi Province. To effectively promote healthy eating, ongoing investment and interventions by local authorities at improving school food culture are needed, with an emphasis on particular factors, such as the eating environment and staff training.

  • This study analyzes the reality of the overall operating system, such as recognition and satisfaction with school field support work system of the Education Facilities Management Center, recognition level of restructuring of work areas, and the direction of improvement for school facility maintenance support in various types of future learning environments. To analyze the problem of this study, a survey was conducted on 290 education administrative officials in Gyeonggi-do. First, school site awareness and work performance satisfaction of the Educational Facilities Management Center were evaluated as "below average," and it is necessary to improve the qualitative work area that is practically helpful to schools. Second, in the area of organizational operation, it is desirable to avoid simple tasks with a low evaluation of "below average" and to switch to an operating system that improves efficiency. Third, the need for the facility environment area (professionalism, safety) was the highest, but the center's ability and work processing level were evaluated very low as "below average," so it is urgent to improve the center's capacity. Fourth, in the area of social and educational policy change, the center received a high score for the need for access from the perspective of a learning environment linked to future education. Therefore, a policy review on the restructuring and improvement of work areas suitable for this is necessary.

  • The Ministry of educational science and technology is about to conduct its 7th &8th curriculum. However, there are some problems in achieving its goals under the current class model system in both educational and architectural. This study finds the characteristics of the arrangements and architectural planning in the departmental system - designed high schools. As a result, the arrangement was tend to be 'overall type' or 'central type' depending on the teaching-learning efficiency. Liberal arts and science&technology groups were placed close, and foreign languages and general cultural studies were arranged close as well. Importantly, there were supporting facilities such as a gymnasium, a cafeteria, a library, a computer lab, and an all-purpose-room, and this arrangement provided convenience. It is for the better learning effect and the high efficiency. It is worthy noticing that the placement and formation of individual or study space is regarded importantly. In flow planning, it seemed that it was designed to reduce the users' movement to a minimum. However, there are still some problems compared to Japan or the States, who already has an established departmental system. I think that the government should enforce its necessity of planning to schools, relevant divisions, or architects to bring it up. Furthermore, it is urgently needed a practical and future-oriented study that can forecast any changes in architectural spaces within the ever-changing teaching and learning environment in the information-oriented society.
