This study was accomplished to analysis and survey on the experimental and practical science education of high school in korea for the consecutive study of the an analysis and survey on the experimental and practical science education of middle school in korea(Lee, Yoon-Jong et aI., 1997). The status of facilities, management for the experiment, practices, teaching methods in high schools have been investigated. The present status and reasonable management of the high school science education have been grasped from the questionaires. To do this 165 high school science teachers, 1977 students and 80 principals of high schools in Korea are administered questionaires of Science Education Research Institute of Kyungpook National University(I997). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the high school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of high school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of high school science education were proposed in this paper.

The scholastic consumer education program in Japan was adopted after world war Ⅱ. And so far, based on home economics class at school, the program has undergone seven times modification with “A course of study(learning coaching guide). Now the main objective with the consumer education program, initiated from ‘purchasing skill’ and ‘information offer’, has been shifted to the direction of stressing the ‘reasonable decision making’ and ‘invocation of consumer recognition’. The concrete operation of the scholastic consumer education program in Japan was managed and operated to the direction of urging the student to think independently and self-motivated and provoking the power of thinking, while utilizing daily works closely to routine life as educational materials and subjects. The investigations on Japanese scholastic consumer education program which have been developing and accumulating concrete instances and know-how's of scholastic consumer education program are considered to be still suggestive, and we may conclude it's necessary for both of Korea and Japan to interchange necessary experiences and ideas on this field with each other.

Recently, the importance of energy demand management, particularly peak load control, has been increasing due to the policy changes of the Second Energy Basic Plan. Even though the installation of distributed generation systems such as Photovoltaic and energy storage systems (ESS) are encouraged, high initial installation costs make it difficult to expand their supply. In this study, the power consumption of a university building was measured in real time and the measured power consumption data was used to calculate the optimal installation capacity of the Photovoltaic and ESS, respectively. In order to calculate the optimal capacity, it is necessary to analyze the operation methods of the Photovoltaic and ESS while considering the KEPCO electricity billing system, power consumption patterns of the building, installation costs of the Photovoltaic and ESS, estimated savings on electric charges, and life time. In this study, the power consumption of the university building with a daily power consumption of approximately 200kWh and a peak power of approximately 20kW was measured per minute. An economic analysis conducted using these measured data showed that the optimal capacity was approximately 30kW for Photovoltaic and approximately 7kWh for ESS.

The purpose of this study is to propose the implications after investigating how gifted education affected the school achievements and academic skills of students who have experience of gifted education. In this study, academic skills include academic knowledge, creative problem solving skills, logical thinking, persuasive skills, collaborative skills, self-directed learning skills, communication skills. The survey was conducted with 1,156 science high school and science academy students who have ongoing gifted education experience and depth interviews were also analyzed with some students to gather further in-depth information. As a result, students responded that gifted education affected very positively on knowledge, collaborative skills, communication skills and increased interest in related subjects. On the other hand, it showed lower positive responses on self-directed learning skills and persuasive skills. Also, students replied gifted education did not affect the school achievements but there was an opportunity to learn how to debate, research, and experiment and practice methods. The direction of gifted education to step forward was suggested based on these results. This study can be the basis for revising gifted education curriculum.

This study aims at revealing important utilization planning by surveying and analyzing unused classrooms in primary school's facilities. That is various and positive utilization planning of unused classrooms in order to cope with the changes of educational environment focused on high and multi-functionization, rather qualitative aspect than quantitative. By field-survey and interview, physical and environmental factors such as, the change procedure of students, unused facilities in schools and improvement affairs and purpose stressed by schools were surveyed. Additionally, the way of educational facilities to future society linked with residents was examined by surveying about the relationship between educational facilities and regional communities. The curriculums and "School facilities standard ordinance" have been revised in part by several times individually and couldn't meet with educational facilities, educational and social change positively. In rural area, to apply the standard of the capacity by a class with 40 students like city is not desirable. To make educational environment better qualitatively, the capacity should be reduced by 30 students and the unit square per a student enlarged by $2.4m^2$. By room unit module "school institution and managerial regulations under high school" should be applied distinctively to break down like 6, 7~12, 13~24 and over 25 classes. So re-institution of the capacity by a class and the standard unit of the number of class by scale is needed.

Objectives : The purpose of this study is to evaluate the preliminary effects of school-based short term mental health awareness and school bullying prevention programs. Methods : From April to December 2013, the Child and Adolescent Mental Health Promotion team of Seoul National Hospital conducted school-based short term social skill training (N=56, 4 sessions), mental health awareness (N=84, 4 sessions) and school bullying prevention programs (N=171, 1 session) in elementary and junior high schools located in Seoul. The changes in the subjects before and after the program were assessed. Results : The social skills training program improved the 'helping' behaviors in boys (t=-2.355, p<.05) and 'sharing' (t=-3.223, p<.01), 'cooperation' (t=-2.235, p<.05), and 'comforting' (t=-2.830, p<.01) behaviors in girls, assessed using the Prosocial Behavior Questionnaire. The mental health awareness program improved 'general health awareness' (t=2.620, p<.05), measured using the Korean General Health Questionnaire. The school bullying prevention program resulted in decreased 'self esteem' (t=3.769, p<.01), measured using the Self Esteem Scale and decreased 'anger' (t=4.198, p<.01), assessed using the Novaco Anger Scale. Conclusion : The results of our preliminary analysis suggest that school-based mental health awareness and school bullying prevention programs may be effective even when conducted for a short term. Future investigation is necessary in order to validate the long term effects of these programs.

This study analyzed the process of establishing a social structure in a third-grade mathematics classroom for one semester and explored learning processes based on various social interactions and relationships between the teacher and students. In the early phase of the semester, main foci were placed on establishing an overall social norms and basic social structure for effective mathematical learning. In the middle phase of the semester, an emphasis among students' interactions was given to exploration of mathematical concepts. Students tended to ask whatever they did not know exactly and clearly understood what to explain. In the late phase of the semester, students' individual disposition was further considered. Disciplinary personality traits including intellectual courage, honesty, consideration, and cooperation were emphasized along with mathematical exploration. Based on these research results, this study was intended to provide implications for implementing more meaningful mathematics lessons by fully considering not only mathematical connections but also social connections.

With the importance of number line in learning fractions, this study investigated how 4th grade students understand fractions and its operations in number line. The questionnaire consisted 22 items which were related to representing fractions, comparing the size of fractions, and operating addition and subtraction of fractions. Both structured number line and sub-structured number line were presented in the items. As results of the study, the overall success rates were not high and even some items showed higher incorrect answer rates than the success rates. Also, the students showed a difficulty in solving non-structured number line tasks. It was also noticeable that students showed several types of incorrect answers, which means that students had incomplete understanding of both fractions and number line. This paper is expected to shed light on elementary students' understanding of fractions and number line and to provide implications of how to deal with number line in teaching and learning fractions in the elementary school.
