The purpose of this study is to develop a measurement tool for self-image of the teacher librarian by semantic differential meaning scale and to analyse the correlation between their self-image and individual characteristics. This study suggests that the teacher librarians have regarded themselves as friendly, planned, sensitive and cooperative persons as well as persons with discernment. On the other hand, there are some negative self-images such as partial, poor and uninfluential persons plus disregarder and a reserved persons. The educational career of teacher librarians' background has influence on evaluation area of the self-image. This result shows that senior teacher librarians' role performance as a adviser or a leader is very important. So mediator role of KLA and KSLA has to be reinforced to beat the exchange and collaboration between the senior and the junior teacher librarians. It is necessary to appoint the teacher librarians obligatorily in oder to feel their professional security and sense of achievement, also to appreciate expertise of them through role clarification among the human resources of the school library.

In order for school library to fully serve as a key educational element of a school, teachers' positive perception on the library's role is essential. Due to the lack of the perception, however, school libraries are not closely related to class activities in practice. Since teachers' perception on school library has been regarded as an given environmental factor in the field of school libraries, alternatives for revitalizing school libraries proposed in previous studies were not effective in practice. We developed a hypothesis that activities in school libraries have a certain impact on the teachers' perception, and tested the hypothesis and identified library factors to the perception in this study. Through a series of statistical analyses with the data from a questionnaire survey with teachers in elementary schools, we identified that the teachers perceived the library as non-curricular element, their perceptions were affected by the library. Consequently, the school library can influence the teachers' perveption. This study has implications to explore practical alternatives to improve the teachers' perception on school libraries by activities in school libraries.

This study examined the conception types of high school students, chemistry teachers, and pre-service teachers about the salt bridge in Daniel cell by a questionnaire and follow-up interviews. High school chemistry II textbooks were analyzed for finding the cause of the understanding difficulties of the teachers and students. Pre-service teachers' thoughts examined for the problems of pre-service teacher programs. From the analysis, it was found that teachers only thought that the role of salt bridge is for ion movement of two solutions involving electrodes. But they didn't have the conception that salt bridge has a roll of connection a circuit. This result was similar to students' and pre-service teachers' results. It was possible that insufficient and different explanations of the textbooks were attributed the teachers' and students' conceptual difficulties.

Many biologists and various educational associations define evolution as a unifying theme as well as a central idea in biology. In this study, teacher education programs were developed as 18-hour courses on understanding the unified role and significance of evolution in biology, and their effectiveness was tested. As factors for the program content, enhancement of the acceptance of evolution, reinforcement of the conception of evolutionary theory, and recognizing and practicing evolution as the unifying nature of evolution were considered. Hands-on activities, self- and peer-evaluation, and projects based on the small teams including frequent questioning and feedback by instructors were considered methodological factors. Six in-service biology teachers and seven pre-service teachers took part in the programs of the graduate school of H university to testing their effectiveness. They were effective in improving the acceptance of evolution, the understanding of evolutionary mechanism, the perception on the unified role of evolution. The programs also induced a positive change in self-evaluation for knowledge of evolution and perception on importance of evolution in biology. Subsequent studies on whether the changed perceptions of the teachers who participated in the programs reflect on their biology classes in secondary schools after finishing the graduate program are required.

The purposes of this study were to examine what kinds of educational activities were carried out during the practice teaching based on CoRe and to identify the role of CoRe and its influence on the development of expertise of student teachers. This study was performed as qualitative case study. The subjects of this study were one practice supervisor teacher and two student teachers. Data were collected through recording CoRe discussion process, student teachers' instructional scene, and semi-constructed interview, and analyzed by an inductive method. Student teachers noticed their own misconceptions, and clarified the concepts based on CoRe during the discussion with supervisor teacher. They also supplemented their lack of knowledge and made up new strategies through the process of sharing their ideas. During the discussion, the supervisor teacher conveyed his teaching experience based on his own orientations toward science teaching. In this course, CoRe plays roles as follows. Firstly, CoRe played a role as guiding supervisor teacher's coaching process. Secondly, CoRe helped for the supervisor teacher to recognize their own PCK. Thirdly, CoRe served as a tool of helping their communication. In turn CoRe proved to be a useful frame for teaching student teachers during practice teaching. Student teachers were provided with a useful framework for preparing lessons by developing CoRe for the topic they teach. Developing CoRe with supervisor teacher at the planning stage of lessons enhenced student-teachers' subject matter knowledge and their PCK including knowledge of science curricula and knowledge of student's understanding of science. Also student teachers understood the components of PCK and experienced the positive understanding toward students, teaching activities, and themselves as a science teacher.

The purpose of this study was to examine the perceptions between teachers and parents on the role and operation of Sejong Special Self-Governing City Early Childhood Education and Development Institute (ECED). The conclusions were as follows: First, more than 96% of the teachers and parents perceived that it was necessary to establish ECED, and the major role of the institute should be providing experience-based educational program. Second, the program of the institute should be organized based on interest induction of children and their creativity development, and cultural art experience-based education was the most desirable program for the weekend. Third, for the teacher support programs, professional development and empathy ability improvement were the key of the program, whereas the parents perceived that communication skills with their children and understanding of child development were essential. As a result, it was obvious that the needs of ECED establishment from teachers and parents were high, and the perceptions of both sides were not different.

The purpose of this study is to find the mediative effects of students' relationship with parents or teachers in the effective path of school violence experience on depression, and to find out the path difference between elementary and middle school students. We used 1,385 students' data collected from the Korean Youth General Survey, and analyzed by multiple group analysis of structural equation. The results showed that elementary school students' relationship with parents or teachers did not play a mediative role. But the middle school students' relationship with parents or teachers play a negative mediative role. It means that if students were damaged by school violence, elementary school students' parents and teachers did not play a specific role but middle school students' parents and teachers caused more depression. Based on these results, some implications for parents and teachers about school violence and depression were suggested.

For teachers to develop new beliefs regarding science teaching and learning, they must undergo a process similar to what they are trying to provide their students. Seventy-one Korean secondary school teachers including 20 earth science teachers have participated in such process. In the four-week long summer workshop hosted by University of Iowa, science teachers were exposed to several activities and lectures wherein they experienced student-centered lessons by playing the roles of both teachers and learners. This study examined the influence of such experience on the teachers’ beliefs about science teaching and learning. Changes in teachers’ beliefs were found in seven question items on the subjects of goals of science learning, the roles of science teachers and students, and classroom practices after workshop participation; it was found that teachers’ beliefs of science learning and teaching shifted from teacher-centered to student-centered. Although this shift does not denote a complete shift from one extreme to the other, it is meaningful to note that teachers’ beliefs after attending the workshop were interpreted to be either anti- or contrary to teacher-centered. One of the possible factors for making such positive changes may have been teamwork or the teachers’ cooperative learning experience.
