This study investigated the high school students' and science teachers' understanding of idealization involved in the physics experiment. Major research questions are as follows: (1) what kind of ideal conditions do subjects identify from the presented experimental context? (2) do subjects think how well ideal conditions are satisfied with the experiment? (3) how well do subjects expect the effect of idealization on the experimental result? (3) what kind of view point do science teachers have about the ideal condition involved in the experiment? A total of 85 subjects were given 6 questions related with the research questions I. 2. and 3. with simple experiment about the brightness of the bulbs connected with parallel to the battery. And another 4 questions for the forth research question were given to 42 science teachers. Subjects' responses were summarized and used to draw the implications for the teaching of physics experiment.

In this study, we explored science teachers' perceptions of adaptive practice in terms of importance and practice. For this purpose, an adaptive practice questionnaire was developed targeting secondary science teachers, and the responses of 128 science teachers were analyzed. The results of this study were as follows: First, the science teachers responded that all 17 items regarding adaptive practice were important. In particular, items related to 'addition of examples', 'adjustment of the level/range of concepts', and 'encouragement of student participation' showed high importance and performance levels. Second, the results of the IPA concerning adaptive practice showed that the items needing intensive improvement due to high importance but low performance were 'encouraging students' self-directed learning' and 'monitoring and responding to individual differences'. The science teachers identified a lack of time and uniform curriculum as the reasons for the low level of practice despite the high importance of these items. Third, regarding the IPA of the adaptive practice items, the items located in the fourth area, an excessive area, concerned 'pace control', 'modifying activities', and 'metaphor use'. More specifically, considering that 'metaphor use' was the only item with a higher level of performance than importance, it is necessary to reconsider whether problems are caused by excessive use. Fourth, analyzing the responses regarding the reasons for the difference in importance and performance revealed that the factors related to teachers included teachers' lack of knowledge or ability, and the tendency to implement as planned. As for student factors, an excessive number of students, differences in the levels of students, and a tendency to prefer classes centered on entrance exams were identified. As environmental factors, a uniform curriculum, conditions for experiments, evaluation systems, and external demands were mentioned. Finally, the implications of the results of this study for science education were discussed.

One of the important competencies in knowledge and information society is the competency of Knowledge information processing. This is closely related to science education and described as one of the core competencies in the 2015 national curriculum revision. Even with a general agreement of the educational necessity of this competency, its practice in class depends mostly on teachers' will. Therefore, we surveyed science teachers' perceptions and classroom condition about the competency of Knowledge information processing, and we analyzed the questionnaires of 64 middle and high school teachers in Seoul and interviewed three teachers. As a result, all teachers shared the importance of Knowledge information processing competency and explained it in terms of social paradigm and goal of the subject. However, there were not many cases of actual practice in class. The teachers answered that time for Knowledge information processing competency is not enough in class and they also lack of PCK on this competency. About half of the teachers had experiences in teacher training about Knowledge information processing competency but most of their experiences are related to information utilization literacy. The importance of Knowledge information processing competency was very high in three factors (collection, analyzation, and utilization), among which information analysis was the highest. Middle school teachers showed higher scores in most questions even though the differences were not significant, and high school teachers showed higher scores in the importance of information sources at a significant level. In order to cultivate competencies, it is necessary to expand the meaning of science inquiry so as to cover this competency and to consider ways of linking with other subjects and develop methods of teaching and learning.

The purpose of this study was to investigate the middle science teachers' perceptions on science lessons with experiments. The study conducted a survey for 110 science teachers participating in inservice program. The middle school science teachers taught classes with lectures rather than with experimental activities. They had an experiment one to three times a semester in their lessons. They did an experiment to follow to what the textbook said, or to confirm it, like a cookbook style. The most teachers answered that they had over average ability to teach both lecture and experiment. Through the experiment, they expected students had interests and curiosity on science. Despite the advantages of experiments, there were many constraints to conduct experiments, such as teachers' excessive work, laboratory conditions, education environment, and others. It was demanded on continuous interest and investment in the variation of educational environment so that teachers can experiment more often.

This study investigated the change of pre-service science teachers' epistemological views of education according to the stages of the field education programs application. For this study, surveys and interviews were carried out threes times before and after participation through participant observation of classes and teaching practices. All data recorded and collected of 28 pre-service science teachers who had answered entire surveys were transcribed and analyzed. The conclusion is as follows; before the participant observation of classes, the pre-service science teachers had views of traditional education affected by epistemology of objectivism. After the participant observation of classes, the views of traditional education increased due to in-service teachers that showed teaching methods through the course of the participant observation. However, it was changed significantly into the views of modern education affected by epistemology of constructivism through the course of the teaching practices. Based on the conclusions of this study, it was identified that the field education programs might have both positive and negative influence on the change of the views of education for the pre-service science teachers. Therefore, Pre-service science teachers should have a opportunity to intensify of constructivism epistemological views of education through the field education programs. The teacher training institutions have to provide systematic and organic cooperation with schools.

In this study, we compared the use of information and communications technology (ICT) by middle school teachers in Korea and other countries utilizing the teacher survey data of the IEA International Computer and Information Literacy Study (ICILS) 2013. The ICILS target population consisted of all students in the eighth grade. We compared Korea with Australia, the Czech Republic, Norway, and Poland, which are nations showing the highest achievements in computer and information literacy. We selected nine questions from the teacher questionnaire and divided them into the categories of computer use, use of ICT for teaching and learning, and the ICT support environment in school. In comparison to their counterparts in other countries, Korean middle school science teachers used computers frequently and also had high ICT self-efficacy. They were confident in their ability to use computers for general tasks, but not in their ability to use computers for teaching and learning. The Korean teachers also had a high percentage of utilization of presentation and graphics software. Also, the proportion of activities concerning the information provided and teacher-led tasks was high, but the proportion of activities for student collaboration or peer interaction was low. In Korea, middle school science teachers had more negative than positive views of using ICT in teaching and learning. The teachers thought that computer-related resource support and digital learning materials were insufficient and that the computer model was outdated in schools. Therefore, we propose to build an ICT infrastructure and to develop and disseminate ICT teaching and learning methods for student activities.

The purpose of this study is to analysis of the cognitions of Korean science teachers and Timor-Leste's science teachers about the teacher training for the professional development as a science teacher held by Korean science teachers. Most of the Timor-Leste's Science teachers who participated at the teacher training mostly had their 10-year teaching career and were secondary school teachers. The purpose of the teacher training is to provide the science educational support for them and to encourage their own development; to effectively donate their skills and talents as a science teacher in their country. The data was collected from participant observation, interviews, and questionnaires. The results were as follows: many Korean teachers recognized that it is necessary to localize the experimental materials and utilize an appropriate language for the science education of Timor-Leste. Furthermore, until the stable science teacher training system of Timor-Leste is set up, it is necessary to be the precise understandings of the curriculum, the correct data regarding the state of education in Timor-Leste, and the knowledge need to Timor-Leste's science teachers. Meanwhile most of the Timor-Leste's Science teachers mostly had some difficulties in using language due to double translation, paying the participant fee, and travelling long distance from their country in participating the teacher training. What they expected at the teacher training was to enhance their professional ability as a science teacher, and to be able to manage the teacher training for Timor-Leste's science teachers by their own selves.

The purpose of this study was to examine interactions among components of pedagogical content knowledge of middle school science teachers in a teacher learning community targeting science practice-based instruction. Data collection consisted of pre and post questionnaire and interview with each of five science teachers, audio-recording of teacher discussion in a teacher learning community, lesson plans, teacher written reflection, and video-recording of teaching practice. Qualitative data analysis revealed that there were two types of interactions, i.e., one-way interaction and two-ways interaction among components of pedagogical content knowledge of science teachers in a teacher learning community. There were also consecutive interactions as well as one-shot interaction. For two-ways interaction there were synchronous two-ways interaction in a teacher learning community meeting as well as consecutive two-ways interaction along with several meetings. This study provides implications that collaborative learning context in a teacher learning community should stimulate various types interactions among components of pedagogical content knowledge.

Environmental education, effectively performed at school, is very important to solve the environmental problems. Moreover the survey for teacher's perception is essential. The purpose of the study was to investigate the perception of environmental problems of middle school teachers in Pusan. The survey was done twice in 2007 and 2012, and based on the time intervals, careers, and major of the teachers. 200 teachers were chosen in 2007 and 300 teachers in 2012. How many environmental problems occurred during this time period affected the 471 teachers' perception was investigated and analyzed. The results are as follows. First, the perception difference of environmental problems was meaningful between two time intervals (p<.01). Especially, the perception of modern environmental problems and carbon emission showed considerable increase in both science and non-science major teachers. This may be caused by the climate change and the severity of lifestyles of indiscriminate consumerism. Second, the perception difference of environmental problems by careers was also meaningful (p<.01). Overall, the perception was obvious on the aspects of modern environmental problems, carbon emission, destruction of ozone layers, nuclear wastes, environmental hormones, and red tides. Teachers, having more careers irrespective of their teaching subjects, showed higher perception on the seriousness of environmental pollution, the necessity of environmental conservation, and the importance of health. Third, the perception of environmental problems between science and non-science major teachers was meaningful (p<.01). Particularly, the perception in the broad environmental problems was distinctive between them.

This study focuses on the current practices and teacher's perceptions of highschool Home Economics Education in Busan, Ulsan and Kyungnam area. Data were collected from 70 teachers with the questionnaire by mail. The results were following : 1. Home Economics have been teamed at schools of class rooms mere than 31, women's high schools and public schools. Teachers more than $70\%$ have operated and lessoned with 4 or 5 among 5 sectors of subject matters, especially emphasized family${\cdot}$human development and food${\cdot}$nutrition sectors. The most difficulties were the shortages of student's interest and reference books. 2. Teachers have cognized highly the connection of Technology${\cdot}$Home Economics and Home Economics, but evaluated lowly the job-course education among the H.E's goals. 3. Necessities of HE were evaluated highly, but student's interests by teacher's judgement lowly. Manual theses of clothing${\cdot}$textile and housing sectors have needs to alter partly. 4. Subject matters to add for the near future revision were related to dissatisfaction of H.E's matters. Teachers cognized problems about the excess, overlap, old-fashioned and irrelevant deepen levels of subject matters.
