This study validated the factor structure of the indicators for measuring pre-service teachers' science teaching-learning competency and analyzed the effects of simulated teaching practice on these competencies. Furthermore, it used response data from 175 pre-service teachers to verify the factor structure of the science teaching-learning competency indicators, and the data from 73 respondents from three departments to examine the effects of simulated teaching practice. To analyze the factor structure of science teaching-learning competency, the content validity index was calculated by five elementary school teachers, and the principal axis factoring with the Promax rotation and reliability analysis were conducted. Moreover, using, a paired sample t-test, the comparison of science teaching-learning competencies before and after simulated teaching practice was analyzed. The study results are as follows. The science teaching-learning competency indicators were revised and supplemented by 30 items under five factors, with a content validity index of .94. The exploratory factor analysis confirmed that 30 items were loaded onto the intended factors, and the reliability of the indicators was found to be .953 (in the sub-factor .829-.918). The paired sample t-test results revealed significant improvement in the pre-service teachers' science teaching-learning competencies before and after the simulated teaching practice. Furthermore, this study verified the significant effect of the simulated teaching practice on the pre-service teachers' science teaching-learning competencies and explained the need for continued implementation of the simulated teaching practice to reflect the specifics of school teaching in the pre-service teacher education curriculum. Moreover, it suggests the necessity of developing evaluation scales for the observer-rated scale, in addition to the self-report scales, to measure the teaching-learning competencies.

I studied on the relations of constructivism and school library assisted instruction in this paper. Constructivism is the most important goal of the modern schooling. In constructivism they insist that knowledge is constructed by the learner individually and subjectively. So in constructivism they focus their attention on setting authentic environment of learning for each individual learner. Constructivism was developed into the learner-centered instruction in schooling nowadays. In constructivism the following instructions are very important for achievement its' goal ; problem based learning, project based learning, discussion based learning etc. These instructions are supported commonly by resource based learning. Educational resources are managed in school library totally. School library assisted instruction is the most effective one for resource based learning. And information literacy instruction by teacher librarian relates closely meta cognitive learning of reflections in constructivism. School library assisted instruction is the essential element for the practice of constructivism in schooling.

The purpose of this study was to develop a school violence prevention program featuring the Practical Action Teaching Model(hereafter, PATM) for middle school students to prevent school violence by Home Economics Education. To accomplish this purpose, the processes of analysis, design, development, and evaluation based on ADDIE were conducted. The validity of the program was evaluated twice by Home Economics education experts(36 experts for the first group and 10 experts for the second group) and the contents of the program were modified according to the comments from the evaluators. The school violence prevention program in Home Economics classes consisted of 5 topics such as changing perception on school violence, enhancing self-esteem, relating with others, practicing consideration and sharing, and strengthening the will of preventing school violence. Twenty-four units were developed with 7 practical problems(What should I do to make friends to help with each other?, What should I do to establish positive self-concept?, What should I do to communicate to build good relationship?, What should I do to solve the conflicts peacefully?, What should I do to practice consideration and sharing in food consumption?, and What should I do to practice consideration and sharing in clothing?) in 5 topic areas. Teaching-learning plans included four steps such as problem perception, practical reasoning, action, and evaluation that comprise PATM to solve the practical problems. Every step of the teaching-learning plan consisted of questions for practical reasoning and activity assignments. Materials for students and teachers were developed. Materials for students comprised 80 pieces in total including student activity, reading, movie, and clips to make students enhance understanding and interest. Materials for teachers comprised 35 pieces in total such as rationales, newspaper articles, and movies that make teachers that lesson teaching loads and were helpful for teachers. The PATM was incorporated into developing the program and a Likert-scale was used to assess usefulness, applicability, appropriateness, fidelity, substantiality, and validity of this program. This program gained more than 4.00 on a 1-5 Likert scale. This result indicated that program is expected to be effective and useful to school violence prevention.

The purpose of this study was to investigate the development and application of strategies using fairy tales in elementary school science. For this study, many fairy tales were searched in terms of various characteristics and educational value of the tales. Five fairy tales were selected and reconstructed to suit the 'mirrors and lenses' unit of 5th graders' school science, and teaching strategies using the fairy tales were developed to be used in six lessons. To investigate the effects of instruction using fairy tales, pre/post tests for scientific attitude were administered. To analyze students' perception of their classes, a simple survey was administered through questionnaires. We found from this study that the students related the fairy tales with their own experiences and took an active part in the class that used them. Also, instruction using fairy tales had positive effects on their scientific attitude. Many students said that the science classes were interesting, and the method using fairy tales encouraged students to study hard as well as helped them to understand the context. It was concluded that instruction using fairy tales was an effective method in terms of enhancing learning motivation, encouraging more inquiries, more opportunities to apply the scientific concept, and more positive scientific attitude. We discussed the strategies using fairy tales for implementation in elementary science classes as well.

This paper reports the results of a recent acoustic survey conducted with the objective of providing on the acoustic conditions of school classrooms in Korea. The measurements included both occupied speech and noise levels during 27 active classes and unoccupied data on the acoustical conditions, and sound insulation performance in 16 classrooms in 4 schools. The effects various parameters on the speech and noise levels in occupied classrooms has been examined. The impact of room acoustic design on speech and noise levels in active classrooms has been also investigated. The speech and noise levels of the elementary school are approximately 4 dBA to 5 dBA higher than those of the other three schools (junior high, high, and special), likely due to the nature of activities involved in group work and the age of the students. A notable 19 dBA difference is observed between the quietest and noisiest classroom activities and the classrooms in which students were observed working in groups with discussion had the highest noise levels. Both occupied and unoccupied data have enabled the establishment of a comprehensive picture of the acoustic conditions in classrooms and have highlighted the necessity of introducing acoustic standards for improving the acoustic environment in Korean schools.
