  • Objectives: The COVID-19 outbreak has resulted in changes in the instructional methods used in kindergartens and daycare centers to prevent viral infections. This study aimed to investigate the changes in oral health care for children before and during COVID-19 and the perceptions of kindergarten and daycare center teachers about oral health care. Methods: The study subjects were 189 teachers of kindergartens and daycare centers in charge of children aged 3 to 5. The data for the analysis were collected through an online survey. Frequency analysis and the chi-squared test were used for statistical analysis. Results: Compared to before COVID-19, the frequency of tooth brushing after lunch, the number of oral health education and regular oral examinations, and the rate of childcare teachers' experiences with oral health education had decreased during COVID-19. In addition, educators in kindergarten and daycare centers responded that an oral health officer at a public health center was the most desirable oral health educator. Conclusions: During the COVID-19 pandemic, the oral health care of children in kindergartens and daycare centers has declined. Efforts are needed to restore it by educating people about oral hygiene care and oral health education, both at home and in kindergartens and daycare centers.

  • The purpose of this study is to understand how a teacher's teaching can be changed while he or she teaches the same contents in different classes. The qualitative research method was used in this study. Data were collected from classroom observations, several in-depth interviews, and stimulated-recall interviews after each class. All the data were transcribed and analyzed interpretively, and then, the results of the analysis were checked by each participating teacher. The results are as follows: First, changes appeared in each class in terms of the teaching items, tools, sequence, and time, even though the same teacher taught the same contents. It showed that the teacher's teaching practice changed immediately and intuitively in class. Second, teachers tried to implement "exploratory teaching" or "move-testing teaching" to address the emerging problems during their teaching. They then reflected on and modified their own teaching. This type of change, which happened during the teaching practice, can be an example of "Reflection-in-practice." Thus, the results of this study can provide helpful insights into how teachers might adapt and reflect in their teaching. It suggests that teachers need to recognize their subconscious teaching changes and learn "Reflection-in-practice."

  • This survey is performed to propose the direction of policy development on reading education for Jeollabukdo Office of Education. To do this, this survey asked 239 teachers who are in charge of each school's reading education. The questionnaire is designed to investigate the effectiveness of current support projects from Jeollabukdo Office of Education, current level of schools' reading education and priorities of policy development. The findings of this survey are as follows: The teachers are contented with current support projects. Each school provides an average of 4 reading programs per year. Elementary schools' level of reading education is higher than middle and high schools' level. And more employment of full time reading experts as teacher librarian and the improvement of school libraries are revealed to be more important priorities on the policy development of reading education. Based on these findings, this study proposed maintenance of current support projects, improvement of school libraries, development of specialized policies for elementary schools, enhancement of reading teachers' expertise and preparation of information sharing system as the direction of policy development.

  • This study aims for developing an instructional design strategy to improve collaborative teaching between teacher librarians and subject teachers in library-assisted instruction. Collaborative teaching is an important management activity enhancing teaching role of teacher librarians in their school community. But in the actual condition the level of the library-assisted instruction as its practical strategy is cooperation and subject teachers are leading teaching and learning except for selecting resources. Because library-assisted instruction is resource-based learning, the procedural knowledge of information literacy curricula and topics of subject specific curricula should be designed as a whole. Also, there must be possibilities of reducing trial and error and expanding successes. From these sides, the collaborative design strategy for library-assisted instruction can be planned like 'statement of learning situation-co designing-co teaching-co evaluating'.

  • The goal of this study is to examine the perceptions of pre-service teachers that directly affect the concepts and ways of the consideration of Earth systems by students studying the water cycle. A concept sketch method was applied to a survey involving 131 pre-service teachers. The survey was designed to analyze the perception of subordinate concepts of Earth systems from the applied components of the water cycle process and to code the applied concepts with components of the water cycle to the subordinate concepts of Earth systems that were the Hydrosphere, the Atmosphere, the Geosphere, and the Biosphere. The survey was designed to examine the perception of the water cycle from the perspective of Earth systems. The recognition by pre-service students was largely confined to components of the atmosphere and the hydrosphere. With regard to the water cycle process, all subjects surveyed recognized precipitation, and most of those expressed recognition of evaporation and condensation. Many of them recognized the surface flow, while they scarcely expressed knowledge of the underground flow.

  • The purpose of this study was to suggest systematic, efficient, and developmental plans for dietary and nutrition education, through analyzing students' perceptions and utilizations of the $\ulcorner$Food and Nutrition$\lrcorner$ area of Technology Home economics in middle school. This study was conducted using self administered questionnaires on general environmental factors, perceptions, and utilization of the $\ulcorner$Food and Nutrition$\lrcorner$ area. The subjects were 807 middle school students of the seventh, eighth, and ninth grades in Gyeonggi province. Most of the students positively recognized the necessity for the $\ulcorner$Food and Nutrition$\lrcorner$ area in Technology Home economics. However, changes in the interest in $\ulcorner$Food and Nutrition$\lrcorner$ after a lesson were not significant. The utilization of the lesson appeared highest in cases where the teachers' instructing methods went abreast with teaching focused on practice or teaching based on practice and theory and if teachers used various teaching materials. These results suggested that teachers should make efforts to raise the students' interest for the lesson in Technology Home economics. Therefore, the contents of the lesson should complement the learners' demands such that they are useful in real life situations. Also, more positive teaching methods and various media which could satisfy the needs and interests of the students should be developed. In addition, teaching methods should be evaluated for an effective and practical curriculum of $\ulcorner$Food and Nutrition$\lrcorner$ in Home Economics.

  • The internet becomes a new communication tool in the knowledge and information society and the people are expanded at the place of information interchange and exchange of view. In recent robot education institutions provide their own official homepages to introduce the robot educational resources. But because they have restrictive searching the functions and providing general robot education resources and don't offer a place that teachers can express their thoughts and share common interests with other users, online community among teachers for robot education and users couldn't have built. In this paper, we propose an Online Robot Education Community(OREC) that teachers and users in different robot education institutions can interchange or share their technical information, learn robot techniques, participate in discussion of their experiences on work, share their common interests, and be provided updated latest news in real-time.

  • Elementary preservice teachers' understanding about the insect molt and metamorphosis was examined. Data were collected through the paper-pencil test of 448 junior students at a National University of Education. The instrument used was developed by Son(2003) and modified for the test. The results are as follows: First, Only 3.1$\%$ of students had a scientific concept on the molt periods in the insect life cycle. Students had an alternative conception that molt occurs either only in the larval period (29.9$\%$) or only in the period from pupa to adult (22.3$\%$). The percentage of the students thinking that molt occurs in the period from larva to pupa was low. Second, 98$\%$ of students stated that molt has to do with the larval growth, but 39.1$\%$ of students had an alternative conception that molt occurs after the larval growth at each instar. 25.1$\%$ had a conception that molt is related with the larval growth, but did not show any further understanding. Third, most students understood the correct meaning of metamorphosis. 34..2$\%$ of students had an alternative conception that metamorphosis occurs only in the period changing from pupa to adult, and only a few thought that it occurs in the period from larva to pupa. 24.8$\%$ of students had a scientific concept on the periods in which metamorphosis occurs. Fourth, some students understood the hatching process as molt in the sense that the egg shell is taken off (21.0$\%$), and as metamorphosis in terms of the appearance change from egg to larva (25.0$\%$). Fifth, 35.5$\%$ of students selected bees as an insect of incomplete metamorphosis, and 35.3$\%$ responded 'I have no idea', showing that they had poor understanding about the insect life cycle.
