The purpose of this study was to examine the types and characteristics of the knowledge constructed by pre-service secondary science teachers. Data included 26 student-teachers' narratives regarding their experiences in teaching high school students who were enrolled in extra-curricular science classes. It was revealed that the pre-service teachers awoke to the importance of subject matter knowledge, and learned it themselves in the situation of their own teaching. Especially their concern about science content knowledge was strongly associated with the matter of didactic transposition of the knowledge. The result also showed that the pre-service teachers constructed knowledge about the relationship with students as well as pedagogical knowledge to help students learn, and that they newly realized the nature of science in the context of teaching science. In addition, the teaching experiences allowed for the student-teachers to develop knowledge of oneself as a teacher and knowledge about science education in schools. It was believed that the knowledge constructed personally by the pre-service teachers from their teaching experiences could be a platform for the development of teacher expertise. Implications of the present study for science teacher education and relevant research were discussed.

This study is to investigate archival use behavior of history teachers in high schools. The study conducted 3 times interviews with high school history teachers and carried out a survey on recognition of archives, archival use, archival seeking behavior, and harrier factors for archival use to 30 teachers from the 2 local communities of history teachers. According to the survey, history teachers have used archives for raising the historical understanding by students in their classes. But the tight curriculums of history and the lack of time to search archives were barrier factors for teachers to use archives in their classes. The teachers who participated in this survey suggested that integrated DBs of archives in Korea and source books with commentaries need to promote use of archives in history classes.

The purpose of this study is to analyze the Korean high-school physics teachers' difficulties in teaching textbook physics inquiries. For this purpose, 63 high school physics teachers completed a questionnaire. We asked teachers to evaluate the degree of difficulty in teaching textbook physics inquiries. Additionally, we asked physics teachers to select the two most difficult inquiries to teach and to express their reasons for these selections. The main results are as follows: First, the degree of difficulty for all the inquiry is 2.79, indicating a little easy level of difficulty. The two most difficult inquiries are 'Meissner effect experiment' and 'Investigation of diode characteristics using $Cu_2O$ plate and ZnO powder.' Second, the difficulty reasons to teach physics inquiry was presented in the order of 'environment domain,' 'textbook domain,' 'student domain,' and 'teacher domain.' In particular, the biggest reasons for difficulty for teachers are 'preparation of experimental apparatus' and 'safety.' There are many opinions related to 'problem of the experiment itself' in 'textbook domain' and 'lack of ability to manipulate' in 'student domain.' Based on the results of this study, we added a discussion to activate the high school physics textbook inquiries.

This study surveyed the elementary school teachers' use of visual representations and their perceptions of the functions of visual representations in the teaching of electricity unit. A total of 110 elementary teachers who have experiences in teaching electricity unit responded to online survey. The result showed firstly that most of the teachers use visual representations in their teaching and it is mostly limited to those presented in textbooks or images that they can get easily from internet search. Secondly, elementary teachers thought that they have high ability in using visual representations and low ability in understanding students' visual presentation ability. Thirdly, visual representations are more often preferred to be used as teacher-centered ways than student-centered ways for motivating students and conceptual understanding. However, in case of scientific inquiry, both teacher-centered and student-centered ways were equally preferred. Lastly, the teachers' perceptions of the functions of visual representations were categorized into 'teaching-instrumental function', 'learning-instrumental function', 'communicative-instrumental function' and 8 subcategories were found. The most frequent function was the 'information delivery function' in the 'teaching-instrumental function' category. Implications for teacher education and further studies were discussed.

This study aimed to investigate the status of happiness according to the background of teachers, and to find out the effects of social support and job satisfaction on teachers' happiness. For this, the data of 249 teachers participating in the teacher training were analyzed using the Google online survey. As a result, there was no significant difference in gender or career, but elementary school teachers were found to have higher happiness than high school teachers. All the sub-factors of social support and job satisfaction were found to have positive relationship with the happiness sub-factors. In addition, in terms of the effects of social support and job satisfaction on inner happiness, teaching consciousness, autonomy, and trustworthy alliance had a positive effect on inner happiness, and the trustworthy alliance, advice, teaching consciousness on external commitment, and social belonging, Autonomy, development, and innovation had a positive effect on self-regulated happiness. It is believed that there is a need to improve the happiness of teachers using the results of this study.

This study examined the types of explanations related to physical change and chemical change in the science textbooks of middle and high school based on the prior study of science teachers' understanding. For this research, the researchers analyzed 44 textbooks of middle school science and high school chemistry. As a result, there were no explanation or property type explanation represented in most of the textbooks related to physical and chemical change concepts. Also, there are few relationship represented between physical change and chemical change, and the examples related to physical change and chemical change were confused. These representations of textbooks can give rise to confusion of understanding of teachers and learners. So, it needs to re-design the explanation types correctly and constantly in science textbooks related to physical change and chemical change.

The purpose of this study was to search for effective strategies on teaching open-inquiry by comparing students' and teachers' recognition of its difficulties and helpful strategies. This study focused on the cases of science high school students and their teachers, who carried out open-inquiry to participate in KYPT. This research was conducted through participant observation, questionnaires, and interviews. The research findings were as follows: students stated that planning and doing experiments were the most difficult parts, whereas teachers viewed that their students had difficulties in analyzing data and making a conclusion. With respect to the effective strategy, students stated that they gained many ideas from peer discussions although they have had to carry out their individual tasks. On the contrary, teachers thought that reference materials and the discussions with teachers were most helpful. There were clear differences between students' and their teachers' recognition toward open-inquiry and the gap needs to be closed. Consequently, it would be useful to guide students to form teams and to spend more time in peer discussions especially when doing experiments and to encourage teachers to understand students' actual difficulties and needs.

This study aimed to identify the difficulties that new science teachers in secondary schools experience. Subjects for this study were 190 science teachers attending qualifying training for 1st degree of teaching certificate. Using an open questionnaire, the difficulties these teachers encounter were collected, categorized, and compared between their first year and their succeeding years of teaching in terms of their school level, gender, majors and regions. Results showed that first year science teachers have had difficulties in areas including subject teaching, guidance, administrative affairs, human relationship and self-understanding. On their succeeding years, difficulties about subject teaching were reduced to half while other difficulties remained. New teachers in middle schools have experienced the most number of difficulties about guidance, while new teachers in general high schools have experienced the most number of difficulties about subject teaching. Based on these findings, some recommendations were proposed for new science teachers in secondary schools, school administrators, and training institutions.
