The purpose of this study is to identify the effect of Teacher Participation-oriented Education Program (TPEP) for Elementary School Teachers to Improve Class Expertise in Science Classes with a focus on visual attention. The participants were two elementary school teachers in Seoul and taught science subjects. The lesson topic applied to this study were 'Structure and Function of Our Body' in the second semester of fifth grade and 'Volcano and Earthquake' in the second semester of fourth grade. The mobile eye tracker SMI's ETG 2w, which is a binocular tracking system was used in this study. In this study, the actual practice time, participant's visual attention, visual intake time average, and visual intake time average were analyzed by class phase. The results of the study are as follows. First, as a result of analyzing the actual class execution time, the actual class execution time was almost in line with the lesson plan after the TPEP application. Second, visual attention in the areas related to teaching and learning activities was high after applying TPEP. Factors affecting the progress of the class and cognitive burdens were identified quantitatively and objectively through visual attention. Third, as a result of analyzing the visual intake time average of participants, there was a statistically significant difference in all classes. Fourth, as a result of analyzing the visual intake time average of participants, the results were statistically significant in the introduction(video), activity 1, activity 2, and activity 3 stages in the lecture type class. The Teacher Participation-oriented Education Program (TPEP) for Elementary School Teachers to Improve Class Expertise in Science Classes can extend elementary science class expertise such as self-class analysis, eye tracking, linguistic, gesture, and class design beyond traditional class analysis and consulting.

In this study, pre-service science teachers' web-based reflective journals were analyzed. During four weeks teaching practicum, they were guided to post at least two reflective journals in a week on the Web bulletin board system. Finally, 307 web-based reflective journals written by 23 pre-service teachers were selected, and the domain and the level of reflective thinking were analyzed. As a result, pre-service science teachers' reflective journals were mostly related with teaching science, i.e., preparing and reflecting their own instruction, and the frequencies of these domains increased with the process of teaching practicum. Reflective journals about school administrative system, informal teaching practice, student guidance, and personal feeling were also included. The level of reflective thinking of 179 journals about teaching science were analyzed further. There were 53 (29.6%) journals including reflective thinking, but the higher level of reflection (professional reflection and critical reflection) was rare. The perceptions of pre-service science teachers on web-based reflective journal writing were also surveyed.

The purpose of this study is to investigate the perception of pre-service elementary teachers on the educational approach to metaverse. Questions about metaverse were asked to 71 pre-service elementary teachers who were taking the course 'Study of Textbooks in Elementary Science II'. The results of analyzing the contents of the questions are as follows. The results and conclusions were presented through numerical analysis and static analysis based on the responses to questions presented using the university's LMS system. First, the level of understanding of the metaverse of pre-service elementary teachers is very high. Pre-service elementary teachers, as the MZ generation, are already living in a very fast IT environment that can be the basis of the metaverse, so it would have been helpful to understand the metaverse. Second, the need for the metaverse of pre-service elementary teachers is very high. There was a tendency to think that the perception of pre-service elementary teachers is because the metaverse has many factors that can provide higher quality education beyond the current educational environment. Third, in the question of applicability exploration in the 'Earth and Space' domain of Pre-service elementary teachers, there have been few cases in which instructional design was planned based on instructional design principles. Based on these results, if the possibility of metaverse application is proposed in the 'Earth and Space' domain, educational contents using virtual space that can transcend time and space will be very necessary. Based on these results, suggestions are made as follows. First, educational content incorporating the metaverse technique based on instructional design should be developed and utilized. Second, financial support should be provided so that the metaverse can be implemented in the educational environment. Third, it is necessary to provide training opportunities for teachers (including Pre-service elementary teachers) to give lectures on metaverse.

The purpose of this study was to examine the oral health behavior and awareness of teachers in community children's centers, the state of oral health care among children in the centers and the opinions of the teachers on child oral health education in a bid to gather information required for the development of oral health education programs geared toward community children's center teachers. The subjects in this study were 178 teachers who worked in 98 community children's centers in the city of Incheon. After a survey was conducted from April 28 to June 4, 2010, the collected data were analyzed. The findings of the study were as follows: The 57.3% of the teachers investigated provided toothbrushing guidance from time to time or couldn't do it at all. As for the reason why toothbrushing guidance was scarcely conducted, the largest group cited shortage of sinks(27.5%) as the reason, and the second biggest group replied they couldn't afford to pay attention to that due to heavy workload(20.6%). The third greatest group was pressed for time(16.7%). The teachers got a mean of 3.27 in oral health behavior, and 87.7% were concerned about children's oral health. The group of teachers who ever received oral health education was significantly better at oral health behavior and showed significant more interest in oral health(p<0.01). The 97.2% of the respondents considered oral health important. Concerning the reason, they replied it was crucial for systemic health (74.2%). The 89.4% of the teachers viewed child oral health education as necessary, and 86.5% had an intention to provide oral health education for children. They hoped to receive education on the oral health control act(4.52) and the prevention of dental caries(4.40). The above-mentioned findings confirmed that in order to step up the oral health promotion of child users of local children's centers, it's necessary to provide secondhand education for them through their teachers who have a great impact on them. Therefore the development of oral health education programs that cater to local children's center teachers is required.

Recent studies say that informal learning is influential to students as much as formal teaming. Nowadays we can see various informal teaming inside and outside of the country. In 2004, it was the first attempt in Korea that engineer had gone to the elementary school fur activity that included scientific experiment and engineering work with students. National Academy of Engineering of Korea (NAEK) progressed activity with companies and elementary schools for students' making sense of engineer and what they are doing. To do that, NAEK had developed the network that company could support its local school's science education circumstance by engineers' visiting program. In 2004, seventeen companies including both large and small ones took part in the program called' Korea Junior Engineering Achievement (KJEA)'. In this program, engineers played the role of teacher (we call them company teacher), elementary school teachers played the role of organizing classes as a mediator. Elementary school teachers and company teachers' recognition is very important to make students' activity meaningful. The aim of this study was to give implication for informal science education activity for which engineers visit their local school. We got the result by survey and interview of company teachers and elementary school teachers. This study's result shows that almost company teachers and school teachers were in favor of purpose of this informal science education activity and satisfied with their participation. But some company teachers were not satisfied with worksheets, materials provided and relationship between school and company). Elementary school teachers and company teachers, both of them believed students' program as the key factor of success of informal science education activity. To make informal science education grow, school administrator and teacher need to have a will to utilize the activities more actively.

The goal of the study was to examine pre-service teachers' emotional experiences, especially during student teaching. The following questions guided this study. First, during student teaching, what are the characteristics of emotional experiences of pre-service science teachers? Second, what are used as the emotional rules and strategies by student teacher? In this study, we tracked nine pre-service science teachers over a four-week period of the student teaching. The data sources were lesson observations, interviews, emotional journals, and video-recorded classroom lessons. Results showed that student teachers experienced various 25 different types of emotions which were reported as the primary emotions of Koreans. The main subjects for interaction for positive emotions were students. For negative emotions, students, teachers and student teachers themselves all resulted in such negative emotional experiences. When the student teachers experienced negative emotions, they followed the emotional rule that their emotions should not be expressed in front of the students. Because of this, they tried various strategies for controlling emotions, such as 'understanding students', 'finding the positive side', 'seeing good students', 'ignoring', 'holding back', 'evading', and 'giving up'. Finally, suggestions for teacher education were discussed.

This study attempted to examine the significance of experience in the gifted class management. The participants of the this study were teachers of the science gifted classe in elementary school located in Seoul. The study was conducted in interviews with four teachers of the science gifted class that individually used their own gifted programs. The interviews were analyzed by applying a phenomenological method of analysis derived from Giorgi. Data collection focused on the feelings, thoughts, behaviors, and changes in life of the teachers of the gifted in order to analyze the experience of the research participants. As a result, 123 significant statements were deduced; based on these significant statements, 26 themes and 12 focal meanings were examined closely. Then, the focal meanings were combined to propose situated structural descriptions of the significance of experiences from the perspective of participants. At the same time, by integrating the situated structural descriptions of the individual participants, the experiences of the teachers of the science gifted class were organized as a general structural description. This study examined in depth the experiences of the teachers of the gifted who are the subjects of the gifted class management through a phenomenological method, and also attempted to examine what these teachers wanted on site and what their experiences with the gifted education meant to them. The implications in understanding the problems of the science gifted education in individual elementary schools and in improving the gifted class management were suggested.

The COVID-19 pandemic has changed everything, even education. Last year when distance learning was introduced, science teachers faced many challenges to overcome. However, teachers adapted quickly, and in this year, it became the 'new normal'. In this situation, teachers are likely to habitually repeat past practices, but the context of the second year of distance learning is changing constantly, and teachers are asked to interpret the problem occurring in a situation and to adjust their practice for solving the problem with their teacher agency. In this study, we explore the emergence of science teacher agency and factors shaping teacher agency in the second year of distance learning and we focus on teachers' agentic practice that did not follow their past practice without reflection. For this purpose, we mainly analyze the semi-constructed interview of three science teachers. In the first year of distance learning, two teachers maintained their practice, not much different to face-to-face learning. However, one teacher reflected upon herself and started to recognize and solve her problems. Reflection for her practice can support this process. Another teacher changed her practice due to external suggestions, but it evolved her practice to fit the situation better, and her experience of last year helped her to adapt to the change. The other teacher who modified her practice to persist her professional purpose last year was consistently practicing in the second year and collaboration and autonomy can support her. This study shows the teachers' dynamic change of agency and the emergence for the relational interaction between teacher and context.

In this study, we investigated how scientists and teachers engaged in mentoring program are conducting research ethics education and how they are creating an ethical educational environment. A questionnaire survey was given to 32 scientists and 44 teachers conducting mentoring programs for gifted high school students. In the content of research ethics education, most of the respondents opined that they should teach against falsification, plagiarism, and fabrication. Teachers were most likely to teach ethical decision-making in each step of the research process. Most of the scientists said that they should teach how to write research note. For the difficulties, the teachers pointed out the challenging system that focuses only on college entrance exams while the scientists answered that it was difficult to recognize research ethics as the problem of the students themselves. For the teachers, the most affective factor in creating an ethical research environment is the amount of time to teach research ethics while for the scientists, it is the ethics of the mentors. For creating an ethical research environment, the teachers responded with making an atmosphere wherein failure is tolerated, and the scientists responded with increasing the degrees of freedom in results. For the difficulties of creating an ethical research environment, the teachers were constrained by research time while the scientists were pressured about the results. These results provide implications for ways to teach research ethics and for ways to create an ethical research environment in the mentoring program for science-gifted students.

The purpose of this study was to investigate the types of questions raised by pre-service elementary teachers when planning a science class utilizing smart technology and the characteristics of their lesson plans. For this purpose, lesson plans and questions written by the 96 pre-service teachers were collected. The results of this study can be summarized as follows: (1) Pre-service teachers used simulation apps, information offering apps, clicker evaluation apps, astronomical observation apps. Simulation apps and clicker evaluation apps were used the most in the introduction stage of the class, simulation apps in the development stage, and clicker evaluation apps in the finishing stage. (2) In the lesson plans, the activities that elementary school students use smart technology showed more than those used by teachers, and its characteristics were more prominent in the development stage of the class. (3) As for the content type of smart technology, experience type was the highest, followed by tool type and resource type. In comparison, there were relatively few interaction support types and learning opportunity extensions. (4) There were many cases in which pre-service teachers replaced elementary school students with virtual experiences using experience type instead of providing opportunities to experiment or experience directly. (5) Pre-service teachers asked various questions while planning science class utilizing smart technology, and a total of 25 question types appeared in 7 categories.
