The purpose of this study was to investigate the environmental awareness and attitude of elementary school teachers. For this study, 100 elementary school teachers from H graduate school of education were sampled. The results of this study were summarized as follows. First, the biggest concern of environmental problems were water-pollution and garbage problems by the lack of understanding about the environment and injudicious development. Second, most teachers recognized the need for environmental education and they answered that they were doing best to teach students with the main purpose of helping them develop values of environmental preservation. Third, most environmental education was carried out during class using current events and the emphasis on garbage separation and recycling. They also showed the lack of teaching materials and field trips for environmental education. Fourth, it appeared to come from media-oriented environmental education. Most teachers mainly used newspapers and visual materials. 1'hey were obtaining knowledge and information related to environmental education through the media. Since in-service teachers' conceptions could directly effect present education, it is necessary to establish a more systematic educational system for environmental education, for in-service elementary school teachers.

Steel-precast ultra-high-performance concrete (UHPC) composite beams with demountable high-strength friction-grip bolt (HSFGB) shear connectors can be used for accelerated bridge construction (ABC) and achieve excellent structural performance, which is expected to be dismantled and recycled at the end of the service life. However, no investigation focuses on the demountability and reusability of such composite beams, as well as the installation difficulties during construction. To address this issue, this study conducted twelve push-out tests to investigate the effects of assembly condition, bolt grade, bolt-hole clearance, infilling grout and pretension on the crack pattern, failure mode, load-slip/uplift relationship, and the structural performance in terms of ultimate shear strength, friction resistance, shear stiffness and slip capacity. The experimental results demonstrated that the presented composite beams exhibited favorable demountability and reusability, in which no significant reduction in strength (less than 3%) and stiffness (less than 5%), but a slight improvement in ductility was observed for the reassembled specimens. Employing oversized preformed holes could ease the fabrication and installation process, yet led to a considerable degradation in both strength and stiffness. With filling the oversized holes with grout, an effective enhancement of the strength and stiffness can be achieved, while causing a difficulty in the demounting of shear connectors. On the basis of the experimental results, more accurate formulations, which considered the effect of bolt-hole clearance, were proposed to predict the shear strength as well as the load-slip relationship of HSFGBs in steel-precast UHPC composite beams.

This study was designed to compare the understanding of ordinary elementary school students and scientifically gifted students about scientists. 473 fourth, fifth, and sixth graders in ordinary elementary schools and 40 students attending scientific educational institutions for the gifted were studied with the help of questionnaires and interviews. The survey showed that there were no significant differences between the two subject groups in relation to the external images of scientists. The subjects turned out to have low fixed external images. The scientifically gifted students had a better understanding of the internal images of scientists than ordinary elementary school students. Both the subject groups fumed out to be influenced by the press media and off-campus education, thinking that scientists served as inventors producing something useful in daily lift rather than as researchers studying natural phenomena or laws. It was found out that both groups admired Edison. The ordinary students respected Einstein and Jang Yeong-Sil whereas the scientifically gifted students respected Curie, Jug Yeong-Sil, and Nobel. The subjects admired them because of their achievements instead of their backgrounds or individual characteristics.

The purpose of this study is to find out the practical problems that 6th grade students are facing, how they perceive Practical Arts education and the praxis of Practical Arts education relating to the problems, and whether the content of Practical Arts curriculum is useful for solving practical problems of 6th grade students. The data used in this study are collected from questionnaires and include in-depth interviews in order to make up for the quantitative research. The major findings of this study were summarized as follows. 1. Elementary school students regarded Practical Arts education as the subject matter through which they learn skills of life. They thought it is useful to their present and future life and to nurture environment-friendly attitude. Furthermore, elementary school students perceive that the meaning of practice in Practical Arts education lies not in praxis as practical action, but in just practice as technical action. 2. According to the survey based on their perception and their practical problems, 66.9% of students answered the learning content of Practical Arts education is not useful in solving their problems. And only 33.4% of students answered the learning content of Practical Arts education is useful in solving their problems. Negative view was predominant among elementary school students. And the Practical Arts curriculum does not reflect much of the practical problems that 6th grade students face. Through these results, Practical Arts education turns out to be hardly related with students' life, though it is the subject matter of students' real life.

In this paper, we propose an effective software education donation model for the social care class. The types of software education for elementary, middle, and high school for the social care class are in the order of after school classes, club activities, creative experiences, and regular classes. In elementary school students, it is effective to precede visual programming education based on block coding and to conduct curriculum convergence with SW and HW at the beginning, and high school students are carrying out text programming education like Python. Software education for social care class The contribution activity model can be classified into five types such as geographically difficult area, multicultural family areas, orphanage, reformatory, and basic livelihood security recipient. In addition, the survey results show that the students' interest in software education and their satisfaction are all very high at 96%. Effective software education for the social care class In the donation model, the lecturers consist of responsible professors, lecturers, and assistant instructors. Software training for the social care class is effective on a year-by-year basis, so that students can feel authenticity and trust. Software education contents focus on visual programming and physical computing education in elementary or middle school, and text programming and physical computing education in high school. It is necessary to construct a software education donor matching system that helps efficient management of software education donations by efficiently matching schools (consumers: elementary, middle, high school) and software education donors(suppliers).
