This paper is intended to investigate the awareness of the elementary school students about the natural environment preservation. For this purpose, 21 elementary school students from the 5th grade of elementary school located in Gwangju city were selected. Especially, we focused on the students' conceptions related to 1) the environments, 2) the safe national land development activity to face several natural disasters and 3) the environmental preservation with the national land development. To evaluate the change of students' conceptions for the national land development, the students were also participated in establishing the plan of the national land development using the model of the natural environment after learning in detail about the natural environments. The results of this study showed that most of the students recognized the concept of the environments as a simple knowledge itself and pollution rather than the protection of environment. In the course of the safe national land development activity to face several natural disasters, the students expressed standardized answer indicating the knowledge based thinking of the environments. According to the results of the environmental preservation with the national land development and the hypothetical project of the national land development, the students did not have enough knowledge for the natural environment preservation although they had understanding of natural disasters and environmental preservation. Therefore, it is necessary to stress affirmative concept for the environment related to the preservation of natural environment. Also we need to develop the syllabus, which is related to the environmental studies, in the elementary educational program leading students to participate in the environmental preservation with the national land development reasonably and practically.

With rapid economic growth, the urban environment has created a problem of human physical and mental illness. In order to solve these problems, urban forests have emerged as a way to mitigate the environmental risks through improving the polluted environment of the city and improve the quality of life. As the urban forests have expanded, the school forests movement has also been taking an important place recently. The study focused on the performance of school forests by comparing the perceptions among teachers and students about their functions. The questionnaire was composed of 4 questions concerning human matters, 10 questions for space recognition, 4 questions for thermal environment, 2 questions for health promotion, and 20 total questions for composition of survey items. The reliability of the school forest function, number of tree planting areas and quantities, the harmony of the planting, and the satisfaction of the school forest were analyzed in the questionnaire conducted by the school members. Although it does not recognize school forests, it has a positive response to the green space that is built outdoors. It is considered that outdoor education and environmental education are sufficient in school forests and green spaces. The results showed that the outdoor green space was more satisfactory when compared with the general school. Teachers and students' preferences were similar to 'seasonal changes' and' trees of various colors and shapes'. The reliability analysis between each item shows that the coefficient for cronbach's ${\alpha}$ was .700 to .834. The purpose of this study is to identify the perception of forest function among school forest members and to utilize them as a basic data in the future.

The purpose of this study is to survey and analyze the environmental awareness and attitude of elementary school students, adapting the CHEAKS(Children's Environmental Attitude and Knowledge Scale) for Korean elementary students, which is the valid-tested tools for children's environmental awareness and altitude. The subjects are 580 students from 6 elementary schools. The differences of the environmental attitude are surveyed and analyzed by environmental education activities, such as environmental activities in school and “the school forest movement”, and environmental awareness and concern. The results are as followings: First, the subjects replied that the environmental problems are very serious, such as atmospheric pollution(37.6%), water pollution(22.2%) and food waste(16.3%), but they are relatively optimistic of the future environment. Second, the verbal commitment subdomain and the affect domain are evaluated higher than the actual commitment subdomain, and the environmental issues of water, energy and recycling are considered more importantly than other issues such as environmental generals, pollutions and animals. Third, the grade and the sex have little effect on the environmental attitude, but the environmental education activities have great positive effect, such as the experience of environmental camping, the education of saving resources, waste separation and the experience of raising plants and flowers. Fourth, the students with high awareness and concern about the environmental problems have high environmental attitude. Especially, the awareness and concern on the flowers and plants have very strong correlation with environmental attitude, regardless of the subdomains. Finally, the students from the school participating “the school forest movement” have relatively positive environmental attitude. Particularly, the participation of students and the positive approach of the school have positively great influence on the students' environmental attitude in all of 3 subdomains and 6 environmental issues.

This study is about development and application of a curriculum to implement physical computing education in an online environment for pre-service teachers. First, a 15-week software and physical computing curriculum was designed according to the ADDIE instructional design model. As a tool that can be used online, education was conducted on a program using various sensors using Pocket Code, an EPL based on a smartphone. As a result of the application of the program, Personal efficacy, Pedagogical knowledge, Technology teaching content knowledge, Result expectation, and Student belief were all significantly improved. In the software attitude part, Software interest and Software value part increased significantly, and the Perception of software engineers did not change. In general, in the case of physical computing, it is difficult to execute in an online environment because it involves a lot of manipulation activity. Through various studies that can continue education in a non-face-to-face environment or a blended environment in the post-corona era, it is hoped that it will be possible to provide a high-quality curriculum to pre-service teachers in charge of future education.

This research is a case study in which teachers tried to improve classes through online class analysis and self-evaluation in elementary school mathematics classes using a checklist of class reflection based on fair access, autonomy, initiative, and evaluation areas in the TRU analysis framework of Schoenfeld (2016). As a result, it was confirmed that the teacher's fair participation, student autonomy, initiative, feedback, and evaluation areas improved teaching methods during the short time. Therefore, if you want to improve classes in relatively short period of time, you can see the effect of some improvement only by self-evaluation. However, continuous improvement of teaching methods require the help of a teacher communities including experts or critical colleagues, and a longer-term case study.

Measurement in elementary school mathematics is one of the mathematical concepts that is directly used in real life. This study is based on the fact that mathematics textbooks for 3-4 and 5-6 graders were developed as the government designed and authorized textbooks and the general measurement instruction process is condensed and presented considering the limitation of the textbook's space for the capacity and weight. Its contents were analyzed. The results are as follows. The contents of authorized textbooks and government designed textbook are different in detail but similar overall in comparative activities, recognition, and situation of the need for the introduction of standard unit and estimation activities. Through this, it is proposed that efforts are needed to reform national textbook policies and develop textbooks that can highlight the meaning of each measurement activity and focus on students' activities.

This study was conducted to investigate nutritional knowledge related to breakfast and dietary behavior of elementary school students by gender and skipping breakfast. The subjects of this study were the 6th grade elementary school students (Total 237; 119 males and 118 females) in Daejeon. The group who ate breakfast six to seven times per week was 58.6%; The group who ate breakfast zero to five times per week was 41.4%. Most of subjects' families (84.4%) were 'nuclear family' and 63.8% of mothers held jobs. There was a significant difference between family income and skipping breakfast. As for the type of breakfast, 79.0% of the male students and 81.4% of female students answered 'cooked rice' and the reasons for skipping breakfast were 'no appetite' followed by 'not enough time', 'over sleeping'. In the eating breakfast group, frequency of having breakfast with family was higher compared to the skipping breakfast group. Total scores of nutritional knowledge related to breakfast in the female students were significantly higher than those of the male students. Also significant differences were found on such questions as 'the relation between eating breakfast and body weight control' and 'importance of breakfast' by skipping breakfast. The dietary behavior scores of the group who ate breakfast were higher than those of the group who skipped breakfast. Therefore, a need exists to develop and distribute a simple breakfast menu that contains Korean-style food and can be more appetizing and appealing to Korean elementary school students. Also it is necessary to develop a systemic awareness program that emphasize the importance of breakfast and the harmfulness of skipping breakfast.

This study explores how the teaching practices of two teachers changed during scientific modeling classes. It also aims to understand these changes in terms of the teachers' modeling pedagogical content knowledge (PCK) development. The study participants were two elementary school teachers and their fifth-grade students. The teachers taught eight lessons of scientific modeling classes about the human body. The data analysis was conducted for lessons 1-2 and 7-8, which best showed the change in teaching practice. The two teachers' teaching practices were analyzed in terms of feedback frequency, feedback content, and the time allocated for each stage of model generation, evaluation, and modification. Teacher A led the evaluation and modification stages in a teacher-driven way throughout the classes. In terms of feedback, teacher A mainly used answer evaluation feedback in lesson 1-2; however, in lesson 7-8, the feedback content changed to thought-provoking feedback. Meanwhile, teacher B mostly led a teacher-driven model evaluation and modification in lesson 1-2; however, in lesson 7-8, she let her students lead the model evaluation and modification stages and helped them develop models through various feedbacks. The analysis shows that these teaching changes were related to the development of modeling PCK components. Furthermore, the two teachers' modeling PCK differed in teaching orientation, in understanding the modeling stages, and in recognizing the value of modeling, suggesting the importance of these in modeling teaching practice. This study can help improve the understanding of modeling classes by revealing the relationship between teaching practices and modeling PCK.

The purpose of this study was to investigate disinfection state and effective factors of utensils and equipments used to foodservice of elementary schools in Busan area, The questionnaire which was administered to 160 dietitians was used in this study as a survey method. The results were as follows. The disinfection method of tray was mainly used by electric gas. Table and other products of stainless steel sanitized by sodium hypochlorite and hot water, but above 51% of slicer. grinder and peeler were not sanitized after used. The products of wood and plastic also used mainly sodium hypochlorite and hot water as sanitizers. In disinfection time, knife, wood spoon and plastic products should be sanitized on demand, but 30.9~53.5% of this utensils except rice scoop were sanitized on demand that showed deficiency of cognition for sanitation. The disinfection of most of utensils and equipments was conducted every day, but food case, slicer, peeler, grinder and wood spoon showed lower disinfection frequency than other products, The method of disinfection was related to dietitians age and career number of total serving, duration of foodservice and serving place, The disinfection time was also affected by dietitians age and educational level, and serving place. The disinfection frequency was affected by number of employee, number of total serving and duration of foodservice. Therefore based on the results of this study, it should be given to the microbiological study on disinfection method of utensils such as slicer, grinder, peeler, large spoon, plastic prouducts and the dietitians sanitation training also should be conducted continuously.
