The purpose of this study is to develop the argumentation program to build scientific concepts on natural selection for science-gifted elementary students and to know how to implement this program. For this study, nine key concepts about natural selection such as the overproduction of offspring, limited resources, population stability, competition, variation, heredity of variation, differential survival, change of the population and speciation were selected through the literature study. The programs were developed by learning cycle instructional model. Argument writings and discourses have been collected, analyzed and compared before and after the program. Two questionnaires to compare pre and post concept change consist of multiple choice questionnaire and open-ended response question were developed and applied to 19 science-gifted elementary students. Sufficiency of the explanation and conceptual quality of the explanation were used to assess the quality of their arguments before and after the program. Discourse and visual models collected from the highest and lowest group about score improvement were compared. The scores of the gifted statistically improved significantly in multiple choice questionnaire. Students' alternative conceptions about natural selection at the beginning of the program decreased and changed scientifically after the program. Visual models drawn by the students supported the results as well. This study asserts that elementary science-gifted students are able to explain evolutionary perspectives about organism change and use the key concepts of natural selection. The study means that evolutionary perspective is possible to be reflected in elementary science curriculum for the gifted.

The purpose of this study is to investigate the features of science classes of Science Core Schools (SCSs) perceived by students. 654 students from 14 SCSs were surveyed with two open-ended questions on the features of science classes. The students' responses were analyzed with NetMiner 4.5, in terms of the centrality (of betweenness and of degree) analysis and the community analysis. The results of the research are as follows: (1) the science classes of SCSs were perceived by students to be of the environment of free questioning, active participation and communication, caring teacher, more science experiments and advanced contents, and knowledge sharing; (2) science classes in SCSs were perceived to be different from those of ordinary high schools because SCSs provide more opportunities for science-related special courses (like project work, advanced science subjects), extra-curricular activities, inquiry and research activities, school supports, hard-working classroom environment, longer studying hours, R&E and club activities. The students' perceptions of SCS science classes appear to be in line with the characteristics of 'good' science lessons from previous studies. The SCS project itself and the features of SCS science classes would help us to see how we introduce educational innovations into actual schools.

2006 CISPR 총회가 스웨덴 스톡홀름 KISTA에서 개최되었다. CISPR I 회의는 9월 18일부터 20일까지 3일간 WG2 및 WG4를 중심으로 진행되었으며, WG1과 WG3 회의는 9월 20일 오후에 있었다. 우리나라에서는 WG1에 두 가지 제안을 발표하였다. 하나는 2004년 중국 상해 회의에서 처음 제안하여 2005년 남아공 케이프타운 회의에서 Task Force가 구성된 대형 시험품에 대한 CISPR 20의 외부 방사내성 시험레벨에 관한 것이다. 2006년 1월 미국 산타페에서 열린 TF 회의에서 시험결과에 대한 기술적 토론이 있었으며, Round Robin Test(RRT)를 실시하기로 결정되었다. RRT시험은 7월 중순에 실시되었으며, 참여한 시험소는 영국의 SONY, 네덜란드의 Philips, 독일의 SHARP 이었으며, 국내의 여러 EMC 시험소도 추후에 참여하였다. RRT 시험의 결과 및 분석이 이번 스톡홀름 회의에서 발표되었다. 또한, CISPR 13의 방사성 방출(RE)의 측정거리 기준점의 변경에 관한 것이다. 본 고에서는 TV 수신기에 대한 RRT 시험결과 및 분석에 대한 발표 내용을 소개하고자 한다. CISPR 20의 외부 전자기장 내성 시험은 0.8 m인 개방형 스트립라인(Open Strip-line: OSL)내에 시험품을 설치하고 $150kHz{\sim}150MHz$에서 시험하도록 규정하고 있다. OSL에 설치할 수 없는 대형기기는 IEC 61000-4-3에 따라서 주파수 범위 $80MHz{\sim}150MHz$까지 동일한 한계치로 전자파무반사실에서 시험하도록 규정되어 있다. 이에 대해 국내 제조업체 및 EMC 전문가들로 구성된 CISPR I 국내 위원회에서는 IEC 61000-4-3에 의한 전자파무반사실(챔버)에서의 내성시험이 CISPR 20에 의한 OSL에서의 내성시험보다 가혹하다는 문제 제기가 있었다. 이것이 본 안건에 대한 배경이다 지금까지 진행되어 왔던 내용을 요약해 보면 2004년 상해 회의에서, 수치해석 및 측정비교를 통하여 CISPR 20에서 규정하고 있는 OSL 전기장 교정방법의 개선의 필요성과 OSL에서 시험할 수 없는 대형 시험품에 대하여 시험레벨을 조정할 것을 지적하였다. 2005년 케이프타운 회의에서는 실제적으로 TV 방송 수신기 및 관련기기가 두가지 방법으로 시험되었을 때 시험결과에 미치는 영향을 시험품의 전기장 내성 레벨로 비교하였으며, 전자파무반사실에서 시험할 경우 시험레벨이 12 dB 낮추도록 보정되어야 할 것을 제안하였다. 2006년 이번 회의에서는 세계 각국의 시험소와 비교시험을 통하여 나타난 OSL과 전자파무반사실 간의 시험결과의 차이 및 이에 대한 원인을 분석하여 보고하였다. OSL과 전자파무반사실 비교시험에서 나타난 차이는 평균적으로 9 dB의 차이로 나타났으며, 주요 원인은 OSL에서 적용하고 있는 시험품을 OSL내부에 설치한 후 시험품에 의해 변경된 전기장의 세기를 보정해 주는 인자(k2)로 인한 차이(6 dB)와 OSL 내부의 전기장의 세기와 전자파무반사실 균일장 영역의 전기장의 세기의 차이(3 dB)이다.

This study addresses the effective utilization of film music as learning material for language, target culture, and ethics education. Music is intertwined with language and culture, and even with ethics. This study focuses on the potential power of film music in the processes of teaching and learning in a classroom. For this purpose, five songs are selected from the soundtrack of Disney's famous animation The Lion King: "Circle of life", "I just can't wait to be king", "Be prepared", "Hakuna Matata", and "Can you feel the love tonight?", and concrete learning activities are suggested based on these. Using these five songs, gap-filling and singing-recoding tasks are proposed as listening and speaking activities respectively. Film music is also very useful in learning vocabulary, sentence structure, and grammar. Learners participate in a writing activity involving creating their own lyrics for the tunes reflecting their experiences. Next, for culture education, a teacher asks their students to discuss about, and be aware of, food culture using a specific character's song. Finally, for ethics education, a philosophy of life, natural logic, leadership qualities, and the motto Hakuna Matata("no worries") are explored and discussed through an analysis of the lyrics. The open-ended questionnaire survey is conducted. The result shows that music has a positive effect on culture and ethics education. Film music can be effective in learning a second language, target culture, and ethics.

This is an action research study of mixed methodology design to confirm the implementation process and effects of applying visual thinking and window paning on improving nursing ethics and professional courses. Based on the conceptual model for action research, a quantitative and qualitative approach was taken. The data was collected and analyzed in an integrated manner. The survey analysis was done using the SPSS WIN 23.0 program. The participants were interviewed after experiencing the techniques in class and content analysis was used on the answers. As a result of applying visual thinking and window paning, ethical decision-making confidence (t=6.748, p<.001) and nursing professional intuition (t=-3.52, p<.001) showed statistically significant changes. There was, however, no significant change in biomedical ethics consciousness (t=1.291, p=.199). Qualitative analysis found that they had fresh experience, an unfamiliar but comfortable feeling, feeling of being mine, insufficient time, systematic case study approach based on theory, were able to cultivate cooperation and coordination ability through discussion and experience in various professional fields, pride, ethical responsibility consciousness and were able to apply learning content in the field. Visual thinking and window paning foster diverse competencies in nursing education and help integrative learning. Therefore, based on the results it is proposed that visual thinking and window paning are applied to the improvement of instruction in other courses to develop core nursing competency.

The purpose of this study was to develop practical problem-based home economics teaching.learning process plans about a unit 'the youth and consumer life' of middle school eighth-grade Technology and Home Economics by applying blended learning(BL) strategy. According to ADDIE instructional design model, this study was conducted in the following procedure: analysis, design/development, implementation, and evaluation. In the stage of design and development, the selected unit was converted into a practical problem-based unit, and practical problem-based teaching. learning process plans were designed in detail by using BL strategy. An online study room for practical problem-based home economics instruction grounded in BL strategy was prepared by using Edunet(http://community.edunet4u.net/${\sim}$consumer2). Eight-session lesson plans were mapped out, and study aids for students and materials for teachers were prepared. In the implementation stage, the first-session teaching plans that dealt with a minor question 'what preparations should be made to become a wise consumer' were utilized when instruction was provided to 115 eighth graders who were in three different province, and the other one was in a middle school in the city of Daejeon. The experimental teaching was implemented for two weeks in the following procedure: preliminary program, pre-online learning, main instruction and post- online learning. The preliminary program was carried out in a session in the classroom, and pre-online learning was provided before the main instruction was given in a session in the classroom. After the main instruction was completed, post-online learning was offered. In the evaluation stage, a survey was conducted on all the learners and teachers to find out their opinions and suggestions.
