  • The most common cause of death in fires is the inhalation of noxious gases rather than thermal injury. Carbon monoxide is well-known toxic component in fire atmospheres. However, the importance of hydrogen cyanide(HCN) as a toxic agent in the fire related fatalities(FRF) is under discussion. HCN is known to be produced in fires involving by the pyrolysis of polyacrylonitril (PAN) and other nitrogen-containing polymer. (omitted)

  • 본 연구의 목적은 과학 분야에서의 집단의 창의적인 성취를 의미하는 '집단 과학창의성'에 영향을 주는 요인을 선정하고, 학생들의 창의적 문제해결 과정에서 집단 과학창의성이 어떻게 나타나는지 탐색하는 것이다. 집단 과학창의성 영향요인을 정하기 위해서 선행연구를 바탕으로 과학교육에서 집단 과학창의성 영향요인 27개를 추출하였고, 과학교육 및 영재교육 전문가들의 의견을 바탕으로 정리하였다. 학생들의 창의적 문제해결 과정에서의 집단 과학창의성 영향요인을 선정하기 위해서 72명의 영재학생들을 대상으로 1박 2일 동안 진행된 집단 문제해결과정을 분석하였다. 주요 연구 결과는 다음과 같다. 첫째, 집단 과학창의성 영향요인으로 인적요인의 9가지 요소(과학적 사고, 과학 지식, 과학 정보 처리 능력, 동기, 도전정신, 구성원의 나이 및 성별의 다양성, 구성원이 선호하는 과목의 다양성, 창의적 경험, 집단응집력), 결합요인으로 4가지 요소(과학적 의사소통능력, 집단의 창의적 과정(과학적 탐구과정), 자율성, 리더십), 환경요인으로 3가지 요소(학습 환경, 교사유형, 외적 보상)를 선정하였다. 둘째, 영재 학생들의 창의적 문제해결과정을 분석하여 집단 과학창의성 영향요인들이 창의적 문제해결에 영향을 미치는 것을 발견할 수 있었다. 이상의 결과를 바탕으로 집단으로서 요구되는 창의적 특성을 신장시키기 위한 요인에 대한 추가적인 시사점을 논의하였다.

  • 이 연구는 미시발생적 연구 방법을 사용하여 초등학생들이 생성한 과학적 의문의 변화를 알아보는데 목적이 있다. 연구 대상은 경기도 소재 I초등학교 6학년 학생 6명으로 학생들은 사이다에 넣은 건포도 관찰 과제와 촛불 관찰 과제로 6회에 걸쳐 활동하였다. 자료는 학생들이 작성한 과학적 의문 생성 활동지, 현장 관찰 기록, 면담을 통해 수집되었다. 연구 결과, 첫째, 초등학생들이 생성한 과학적 의문은 회기에 따라 감소하는 경향을 나타내었다. 둘째, 과제에 따라 과학적 의문 생성의 변화 과정이 다르게 나타남을 확인할 수 있었다. 셋째, 각 개인에게서 일어나는 과학적 의문의 유형 변화를 살펴봄으로써 동일한 과제에 대해회기에 따라 다른 결과가 나타나고 각 개인에게서 나타나는 변화 패턴이 다양하다는 것을 알 수 있었다. 즉 과학적 의문 생성활동에서 학생들은 개인 내 변산성과 개인 간 변산성이 존재함을 확인할 수 있었다. 따라서 이 연구의 결과는 과학적 의문 생성 지도에 다음과 같은 시사점을 줄 수 있다. 학생들에게 있어 과학적 의문의 생성은 지식의 성장, 획득 과정을 경험할수 있는 기회를 높여줄 수 있기 때문에 과학적 의문을 생성할 수 있는 상황을 조성하는 것이 중요하며 다양한 유형의 과학적 의문 생성을 위해 과제 선정 시 과제 속성에 대한 분석이 필요하다.

  • This study analyzed the types of scientific humors made by scientifically-gifted elementary school students and their perceptions of making scientific humor. For this, 77 students from $4^{th}$ to $6^{th}$ graders of gifted science education center in Seoul National University of Education were selected. Scientific humors made by the students were analyzed according to the number and types. Their perceptions of making scientific humor were also analyzed through a questionnaire and group interviews. The analysis of the results revealed that most of scientifically-gifted students made more than 2 scientific humors, and the number of scientific humor for each students varied from 0 to 11. The most types they made were the descriptive type and the pun using pronunciation type, but they made various types without any special type to be biased. And They made more the dialogue type than the narrative type, especially the riddle type. They used scientific knowledge that preceded the knowledge of science curriculum in their grade level over two or more years. The scientific knowledge of chemistry was used more than physics, biology, earth science and combination field. The name utilization type was more than the characteristic utilization type and the principle utilization type. Scientific humors in the everyday situation were more than humors in artificial situation. The students had various positive perceptions in making scientific humor such as increase of scientific knowledge, increase of various thinking abilities, deep understanding of science concept and principle, increase of interest and motivation about science and science learning, and increase on sense of humor. They had also some negative perceptions related to difficulties in the process of making scientific humor, lack of fun, and lack of time in the class.

  • This study aimed to develop a convergent arts and science program for 5yearold children and to evaluate this effectiveness of the program. To meet the purpose of this study, 34 children (aged, 5 year) were divided into two groups, namely the experimental group and the control group. To the experimental group, the creative arts and science convergence program of interest in this study was delivered over a period of 8 weeks. The children of the control group were delivered the Nuri Curriculum (standardized educational curriculum targeted for 3- to 5year olds) during the same experimental period. The levels of the children's creativity were assessed using the Torrance Test of Creative Thinking-Figural and those of their scientific inquiry ability were tested by using the Scientific Inquiry Ability Assessment Scale. The analysis of covariance calculated using by IBM SPSS ver. 21.0 revealed that the experimental group scored higher in creativity and scientific inquiry than did the control group. The results indicated that the proposed convergent arts and science program was effective in promoting creativity and scientific inquiry ability of young children. In this paper, along with the main results of this study, the implications for research and practice are discussed.

  • The purpose of this study was to identify the influence of emotional intelligence and achievement goal orientation on career maturity for elementary scientific gifted students. For this purpose, emotional intelligence test, achievement goal orientation measure and career maturity test were used. Sample of the study was consisted of 107 science gifted students and 98 general students in Y City, Gyeonggi Province. The results of this study were as follows. First, scientific gifted students showed higher score than general students, whereas general students had highest score in type of avoidance goal orientation of achievement goal orientation. Also, scientific gifted students showed highest score in mastery goal orientation of those. Second, the correlation between emotional intelligence and career maturity of scientific gifted students showed significantly positive score in almost all the subelements. As a result of conducting a regression analysis on the influence of emotional intelligence on career maturity of scientific gifted students, job planning and self-understanding of career maturity were impacted by emotional intelligence, whereas independence was low influence by emotional intelligence. Third, for the correlation between achievement goal orientation and career maturity of scientific gifted students, mastery goal orientation of achievement goal orientation had positive relationship in almost all the subelements, whereas mastery avoidance goal orientation and performance-avoidance goal orientation had negative correlation. Also, as a result of conducting a regression analysis on the influence of achievement goal orientation on career maturity of scientific gifted students, achievement goal orientation had influence on all the subelements of career maturity.

  • This study aims to develop a scientific creativity task which science-gifted elementary students can conduct on a field trip to a botanical garden, and to analyze the results from conducting the task. For this, 38 science-gifted fifth-graders from the Science-Gifted Education Center, located at the Office of Education, participated in a field trip to a botanical garden, as a part of their program. Prior to the program, researchers developed a scientific creativity task for outdoor education program, along with science education specialists and teachers. The tasks were to observe plants, and to create something new and useful, or, in other words, scientifically creative, based on the plants' characteristics. The students could submit at most three ideas. Also, they assessed their own ideas, and selected an idea that they thought was the most creative. The results were analyzed by using the scientific creativity formula. The main findings from this study are as follows. First, it was found that the scientific creativity formula had an upward bias in assessing originality. Second, the students tended to assess the usefulness of their own ideas more generously. Third, the correlation between self-assessment results and scores from the scientific creativity formula for originality was r=.43. Fourth, in formula-based assessments, the correlation between originality scores and usefulness scores was relatively high, at r=.56. Fifth, the correlation between a student's scientific creativity score and the number of his or her ideas was very low, at r=.23. Sixth, when the ideas chosen as the most creative by students were compared with the ideas that had the highest scores in formula-based assessments, it was shown that 8 out of 19 students (42.1%) did not choose the idea that appeared to be the most creative when graded by the formula. This study is concluded by discussing the lessons from the scientific creativity task analysis for primary science education and gifted education.
