The purposes of the study are to portray Korean beginning secondary science teachers' ways of arranging science content, sense-making strategy, and factors contributing to the tensions between teachers' intentions and actual practice. Six beginning secondary science teachers participated in this study. Science classes taught by the participating teachers were observed and videotaped. Semi-structured interviews were conducted for science teachers participated in this study after science classes were observed. Instructional materials were also collected for each science class. Video- and audio-taped data were transcribed and analyzed using conceptual framework developed by the Michigan State University. The findings of this study produce the following conclusions: (1) beginning teachers' science classes are arranged in ways compatible to traditional school science, (2) frequently used sense-making strategies are procedural display and narrative reasoning, (3) tensions between beginning teachers' intentions and practice arise from two factors such as assessment and differences in educational views with peer teachers, and (4) learning experiences, lack of perceptions and preparations on reform science teaching, and the absence of systematic program for professional development programs for beginning science teachers are major obstacles to reform science teaching for beginning teachers.

Study courses using cognitive conflict strategy about geological stratum were performed on the 6th grade elementary students and their conceptual changes were investigated. Some misconceptions about geological stratum that the students have are as follows: (1) stratum was formed due to volcanic eruption, (2) gneiss composes the geological stratum, (3) folds in the stratum were formed due to vertical pressure from the top. The classes had positive effects on the changes of some the misconceptions: (1) the places where the stratum is filmed, (2) the kind of rock in the stratum, and (3) the reason for folding. However, there were no significant changes in the following items: (1) the reason that every layer consists of different sizes of grains. It shows that some misconceptions can be changed easily by cognitive conflict strategy, while others can not. We checked the students who didn't change their misconceptions after the test. These students have very strong misconceptions that most of the natural phenomena on the earth's surface are due to the internal heat pressure, and volcanic activity. Another affecting the students' misconceptions are the role of teachers in class and mass media, such as TV.

There are complex interactions between personal and contextual features in teaching in a science museum. In order to analyze two teachers' holding classes in a science museum, the CHAT (cultural historical activity theory) was used as an analysis tool in a case study. The analyses of the results revealed that both teachers had difficulties teaching in a science museum due to the contradictions among the factors of subject, rules, community, and division of labor in the activity system. Although both teachers had trouble with similar contradictions, there appeared to be different sets of internalization and externalization of such conflicts depending on the difference in the teacher's perceptions and experiences about teaching in a science museum, the passion and the motivation of the teachers. These suggested that efforts should be preceded to foster the activity system providing both emotional and social supports to teachers in order to activate teaching in a science museum. Taking a teacher training course on teaching in a science museum was also found to fail to function as mediating artifacts. The course should provide not only the experience of executing proper teaching strategies for teaching in a science museum and the feedback on their teaching, but also the guidance on how to lead to optimal expansion of the factors in the activity system.

The purpose of this study is to examine the effect of private tutor's job stress on the organizational commitment and turn-over intention and to verify the mediating effect of the organizational commitment. The questionnaire survey was peformed for 332 private tutors in special education region in Seoul. The collected data were used as a model of path coefficients obtained through analysis of structure equation model(SEM) and hypothesis verification. The result of the verification is as follows. First, both stress by student and stress by administrative support showed statistically significant negative effects on the organizational commitment. Second, the private tutor's organizational commitment showed a statistically significant negative effects on the turn-over intention. Third, both stress by task and stress by conflict in organization showed statistically significant positive effects on the turn-over intention. Fourth, even if both stress by student and stress by administrative support showed statistically no significant effects on the turn-over intention, they showed statistically significant effects on the turn-over intention with the mediating effect of the organizational commitment. It was confirmed that the turn-over intention can be decreased by relief of the private tutor's job stress and enhancement of the organizational commitment. In this process, it is meaningful to verify the role and function of the private tutor's organizational commitment.

This study explored the elementary school teachers' experiences while teaching students with low achievement in science based on the grounded theory. In-depth interviews and analysis were conducted on 13 teachers with experiences in teaching students with low achievement in science within the last three years and more than five years of field experience until the theoretical saturation of data on the teaching experiences for students with low achievement in science. The analysis results were as follows. First, the teaching experiences of elementary school teachers for underachievers in science were classified into 119 concepts, 41 subcategories, and 17 categories. Based on the paradigm model, the categories were structured and presented as causal conditions, contextual conditions, intervening conditions, action/interaction strategies and consequences based on the central phenomenon of 'difficulty in teaching students with low achievement in science'. Second, the core category of elementary school teachers' teaching underachievers in science was assumed to be 'overcoming difficulties and teaching underachievers in science'. And according to the properties and dimensions of the core category, teachers who teaching students with low achievement in science were divided into four types: 'compromising-', 'overcoming-', 'accepting-', and 'conflicting-reality type'. Third, a conditional matrix was presented to summarize and integrate the results of this study by classifying the teaching experience of elementary school teachers for underachievers in science into educational providers and educational demanders. On the basis of these findings, educational implications for teaching students with low achievement in science were discussed.

This study is to investigate the perceptions of high school teachers on the evaluation criteria of the college admission officer interview system and to suggest approaches to improve the interview system. The survey results of teachers' perceptions are the following. First, for 'potential' criteria, teachers consider challenging spirit and students' initiatives are important evaluation criteria. For 'personality' criteria, they contemplate that responsibility, community spirit and flexibility to resolve conflicts are important values. Further, views of life and creativity also need to be seriously considered in the screening process. Second, their satisfaction with the college admission officer system was relatively high (9.34 points). Last, in order to improve the interview screening system, teachers assert that the process to secure fairness is required. Based on the results, suggestions were made for ensuring expertise of college admission officer and improving the alternative policy of the admission officer interview system.

The purpose of this study is to explore the characteristics of secondary science teachers' thoughts on 'good' science teaching and to find a concept that can represent the way the teachers think. Participants were twenty pre- and in-service teachers who were enrolled in a graduate course I taught at a university located in Seoul in the first semester, 2011. The participating teachers collected and analyzed a variety of data and created portfolios while they were trained, as part of the course, on qualitative research methods with the same research questions as those of this study. In the current study, the process in which the teachers and I found answers to the research questions was narratively reconstructed based on the teachers' portfolios and my field notes. It was revealed that science teaching was perceived as a task aiming at realizing some kind of values and that because the teachers pursued various values in the science classroom and there exist conflicting relationships among different values, it was hard to define 'good' science teaching. It was also discussed that science instruction was inherently accompanied with the ongoing process of selecting values as the relationships among the values were ever-changing within the contexts of the classroom. This multi-faceted and dynamic structure of the teachers' thoughts on 'good' science teaching was conceptualized analogically as 'Foucault's pendulum,' which has multiple planes of oscillation. Implications for science teacher education and science education research were suggested.

In this study, we analyzed the written and drawn explanations of thirty elementary school pre-service teachers in order to examine their perception on the seasonal length of day and night. The main findings are as follows: First, pre-service teachers used the most common term in the description of the texts, such as meridian altitude, axis of rotation, and revolution, and there were more misconceptions in the drawn explanation than in the written explanation. Second, by analyzing the pre-service teachers' perceptions by combining written and drawn explanations, it is possible to detect scientific errors that the distance between the Earth and the Sun is closer when the axis of rotation is tilted in relation to the revolution and seasonal changes due to changes in the orbital radius of the Earth. In addition, there have been types of explanations such as seasonally changing meridian altitudes related to the rotation of the Earth but no change in the location of the Sun. Based on the results of the analysis, we discussed the lack of experience in constructing an explanatory system of specific phenomena using scientific knowledge, lack of observational experiences about natural phenomena, and lack of exposure to other explanatory systems that cause cognitive conflicts. We hope that it will be concrete and practical help to improve the understanding of pre-service teachers in the science domain of primary teacher training program.

This study aimed to identify the factors that helped and hindered secondary school teachers who experienced student suicide using the concept-mapping approach. Seven South Korean middle and high school teachers were interviewed from which 113 core statements were elicited. The participants sorted these core statements into categories by meaning. Multidimensional scaling and hierarchical cluster analysis were conducted to identify the underlying structure of the teachers' experiences. Four hindering factor clusters emerged: (1) regret over failing to prevent the suicide, (2) an apathetic atmosphere in the school, (3) a sense of helplessness related to suicide survivors, and (4) approach-avoidance conflicts related to suicide survivors. Six helpful factor clusters emerged: (1) cooperation and care offered between suicide survivors, (2) focusing on the present, busy life, (3) spiritual activity, (4) social support, (5) overcoming grief through altruistic behaviors, and (6) sympathy for the deceased. Two dimensions were found for both the hindering and helpful factors. The hindering factor dimensions were external system-internal experiences and related to suicide survivors-related to suicide decedents. The helpful factor dimensions were distancing from the loss-approaching the loss and professional activities-personal activities. The present study empirically explored and described the underlying structure of teachers' bereavement experiences after student suicides.

This study aims to determine the perspectives of pre-service elementary school teachers on the science curriculum in the fourth industrial revolution era. In this study, 128 pre-service elementary school teachers were asked to express their perspectives on the Saber-toothed Tiger Curriculum through photovoice activities. The resulting images were classified into three types: conservative, progressive, and radical perspectives. The number of both conservative and progressive perspectives was similar and high, whereas the number of radical perspectives was l ow. Those who had conservative perspectives on the Saber-toothed Tiger curriculum regarded "Inquiry" as the basis of the science curriculum, which should be maintained regardless of the time period and environment. Similarly, older teachers believed that this curriculum was based on eternal truth, which should be protected. Those who showed progressive perspectives on the Saber-toothed Tiger curriculum regarded a progressive person as someone succeeding to the blood of "New fist," and they showed positive attitudes toward AI-based education such as coding and meta-verse, regarding these practices as part of the teaching and learning method that could replace the existing inquiry-based education. Those who showed radical perspectives on the Saber-toothed Tiger Curriculum assumed critical attitudes toward the rapidly changing political circumstances of science education and criticized conflicts between different social classes formed through progressive curriculum. Based on these results, this study found that pre-service elementary school teachers needed to consider the science curriculum from several different perspectives rather than just one.
