The purpose of this study was to investigate and analyze the conception of elementary school students on evaporation and condensation, and then to verify the types of the conception. Forty-eight children from six elementary schools were sampled by stratified random sampling in Seoul and other provinces. They responded to the questionaire and the interview. This study was carried out according to the process of the basic study, the preliminary study, and the main study. The materials collected were classified and analyzed according to the types of children's ideas. The findings of this study were as follows: 1. The vocabulary used to describe the evaporation phenomena varied according to the situations, and the scientific term "evaporation" was more frequently used by the older groups. 2. Most children answered that the last location of water were air/sky/cloud. Air/cloud which represents the scientific conception of the location of water were mentioned by children of all ages. The higher the grade of the children were, the more scientific conception the children mentioned, however. 3. Most children referred to the heat as the factor of evaporation. Wind, on the other hand was mentioned by less than 10% of lower graders, and by about 30% of higher graders. 4. The result of asking children whether they thought it was possible to get the evaporated water back showed that about 70% of lower graders denied the possibility of the water being reversible. About 60% of higher graders, however, recognized that the water will be returned as rain or condensation. This increase may be associated with formal teaching of water cycle. 5. In the ideas of evaporation and condensation, some of the children have supernatural ideas and animism, which are most younger chilren's characteristics.

최병순,박소영,이정오 대한의학회 2010 Journal of Korean medical science Vol.25 No.-

This study identifies the number of pneumoconiosis patients after eliminating deceased patients between 2003 and 2008 as of January 1st and estimates it for the next five years. From 2003 to 2008, the pneumoconiosis patients were 16,929, 17,224, 17,366, 17,566,17,542, and 17,546, respectively. The number of pneumoconiosis patients will have increased by 1,014 from 2008 to 18,560 in 2013 after applying the average change rates taken from 2003 to 2007. It takes 15-20 yr to develop coal workers’ pneumoconiosis (the main cause in Korea) and patients will continue to be diagnosed with pneumoconiosis for some years to come since it has only been 20 yr since the decline of the coal mining industry in Korea. In addition, pneumoconiosis patients are increasing in industries in which the risk of pneumoconiosis was relatively low shows the necessity to improve dust-exposed workplace environments.

국가 수준의 과학 지식 평가 체제 개발 : Scientific Knowledge Domain

최병순,권재술,김찬종 한국교원대학교 과학교육연구소 1998 청람과학교육연구논총 Vol.8 No.1

과학교육의 정책 수립과 평가 및 과학교육과정의 개편과 효율성 점검 등은 체계적이고 과학적인 연구 결과를 바탕으로 해야 한다. 이를 위해서 주요 선진국에서는 국가 수준 과학 학력평가를 지속적으로 실시하고 발전시켜 왔다. 우리 나라에서 그 동안 실시된 국가 수준 과학 학력평가는 많은 문제점을 가지고 있는 것으로 지적되어 왔으며, 과학 교육 정책 수립 및 평가 그리고 교육과정 개편을 위한 자료 제공에 성공하지 못하였다. 이 연구의 주요 목적은 우리 나라 초·중·고 학생들의 과학 지식 성취의 경향성을 파악하고 향후 주기적으로 진행되어질 국가적 차원의 평가 지표를 만들기 위한 국가 수준의 과학 지식 평가 체제를 개발하는 것이다. 과학교육전문가와 초·중·고 교사들로 연구팀을 구성하고, 교육평가 전문가들과의 협조와 자문을 통해서 국가 수준 과학지식 평가 체제의 방향과 주요 요소를 결정하였다. 또한 문항 개발을 위한 세미나와 워크숍을 통해서 평가문항개발 능력을 향상시켰으며, 계획한 문항을 개발하고, 수정하였으며, 초·중·고교생 958명을 대상으로 예비검사를 실시하고 그 결과를 바탕으로 최종 문항을 380개를 선정하고 수정하였다. 최종 선정한 문항은 다시 초·중·고 학생 8766명을 대상으로 본 검사를 실시하여 문항반응이론(IRT)을 이용하여 문항의 특성을 분석하였다. 연구 결과 국가 수준 과학 지식 평가는 매년 초등학교 5학년, 중학교 2학년, 고등학교 1학년과 2학년을 대상으로 학년말에 실시하는 것이 바람직하다. 표집은 다단계 유층화 표집 방법을 사용하며, 검사지는 복수형으로 개발하며 가교문항을 활용하여 검사지간 학교급간, 종단적 비교의 기초로 삼는다. 본 연구에서는 국가 수준 과학지식 평가 체제를 위하여 각 모집단 별로 문제 은행에 포함시킬 80 내지 100문항씩 총 380문항을 개발하였다. 개발된 문항과 검사의 특성을 분석하여 본 결과 초등학교용 문항들은 중간 또는 중간 이하의 능력을 가진 학생들에게, 중학교용과 고등학교 1학년 용 문항들은 중간 또는 중간 이상의 능력을 가진 학생들에게, 고등학교 자연계용 문항들은 비교적 높은 능력을 가진 학생들에게 적합하였다. 개발한 문항들의 변별도는 우수하거나 매우 우수한 것으로 나타나서, 학생들의 과학 지식 성취를 정확하게 평가하는 데 적합한 것으로 보인다. Establishing and evaluating science education policies and revising and monitoring the effectiveness of science curriculum should be based upon the results of systematic and scientific research studies. Advanced nations have already been administering and developing national level science assessments for these purposes. The science assessments administered in Korea have been reported having many limitations and problems, and not succeeded in providing data for science education policy making and curriculum reform. The major purpose of the study is developing national level science knowledge assessment system in order to identify longitudinal trends of elementary and secondary school students science knowledge achievements. The research team consisted of science education experts and teachers from various school levels, decided the directions and major elements of national level science knowledge assessment with the consultation of educational evaluation experts. Item developing ability of the researchers was improved by seminars and workshops on national assessment in advanced nations and developing skills of writing science items. Nearly 500 items were developed and revised. Pilot test was administered with 958 students at various school levels. 380 items were selected and tested with 8766 students, and the characteristics were analyzed in terms of item response theory. The target populations for national level science knowledge assessment are 5th-grade of elementary school, 2nd-grade of middle school, 1st and 2nd-grade of high school students. The proper period for the assessment is February every year. Multi-stage clustered sampling method is desirable and rotated forms are recommendable for the test format. Bridge items should be introduced to compare the results of multiple tests, and various grades. Anchor items should also be used for longitudinal interpretations of the results. The items for elementary school require low to medium abilities, for middle school and first grade of high school require medium to high abilities and for 2nd-grade of high school high abilities. The discrimination ability of the items developed is high.

In order to develop effective environmental-friendly seed treatments for Bakanae disease caused by Gibberella fujikuroi in rice seedlings, we investigated the effects of dry heat, chemical and warm water treatments on seed germination, seedling growth, and infection rate of Bakanae disease in contaminated rice seeds, and tried to find out the maximum high temperature limits and post treatment conditioning for rice seeds. The results showed that germination and height of seedlings as affected by warm water and chemical treatments were similar, and disinfectant efficiency was good in combined treatment with warm water and chemical treatments. Although warm water and chemical treatments did not show serious infection rates, some dry heat treatments showed varying infection rates. These varying infiection rates could be significantly reduced by increasing the maximum temperature of dry heat treatment even though seed germination was also decreased by high dry heat temperatures. Therefore, between 80℃ to 85℃ of maximum and 3 days of post conditioning treatments of dry heat treatment should be applied for disinfection of rice seed for Bakanae disease. These results indicated that dry heat treatment may be effectively used as one of the major environmental- friendly seed treatments.

지필평가에서 나타난 학생들의 탐구능력과 실험과정에서 보여주는 탐구능력과의 관계 연구

崔秉舜,金東燦,南貞嬉 한국교원대학교 과학교육연구소 1993 청람과학교육연구논총 Vol.3 No.1

본 연구에서는 지필평가에서 나타난 학생들의. 탐구능력과 실험에서 보여주는 탐구능력과의 상관관계를 알아보았다. 이를 위하여 학생들의 탐구능력을 탐구과정 요소별로 비교분석하고, 이들 탐구능력 사이의 상관관계를 알아보았다. 연구결과에 의하면, 지필평가와 실험평가에서 나타난 탐구과정 요소간의 상관관계가 가설설정, 실험설계, 추리, 변인통제에서는 비교적 높은 편이었으며, 결론도출은 통계적으로 유의미한 상관관계가 없는 것으로 나타났다. 두 가지 평가방법에 의한 탐구능력의 평균점수를 비교해 본 결과 가설설정, 추리, 결론도출은 평균간에 통계적으로 유의미한 차이가 있고, 실험설계와 변인통제는 차이가 의미없는 것으로 나타났다. 따라서 실험설계 능력과 변인통제 능력은 지필평가만으로도 측정이 가능하나, 가설설정, 추리, 결론도출능력은 지필평가만으로 측정하기 보다는 실험과정에서의 평가에 의한 보완으로 보다 정확한 탐구능력의 측정이 가능하리라 판단된다. The purpose of this study was to find the relationship between the inquiry ability in written test and that shown in the laboratory experiments. For this study, inquiry ability of the students was measured and analyzed in the written test and in the course of general chemistry experiments, and then correlations between them were obtained. According to the result of this study, it was found that correlations between each inquiry element in written test and that shown in the laboratory experiments were ranged from 0.2000 to 0.5866. In formulating hypothesis, designing an experiment, inference and controlling variables, the correlation was significant each at 0.01 level. But in drawing conclusion, the correlation was not significant. By the comparison of the means between inquiry element in written test and those shown in the course of experiments, it was found that there was significant difference in hypothesis formulation, inference and drawing conclusion. But in designing an experiment and controlling variables, there was not significant difference. Accordingly, it was considered that designing an experiment and controlling variables ability were possible to be measured by written test, and that formulating hypothesis, inference and drawing conclusion ability should be measured by laboratory experiment test as well as written test.

최병순,김충호,이상권,Choe, Byeong-Sun,Kim, Chung-Ho,Lee, Sang-Gwon 대한화학회 2002 대한화학회지 Vol.46 No.4

이 연구의 목적은 일반고와 과학고 학생들의 정신용량과 산화 환원 개녀 이해 정도가 산화 환원 반응식 완결 문제의 성취도에 미치는 영향을 분석하여 이러한 화학문제 해결에 대한 효과적인 학습 지도 방안 마련에 도움을 주고자 하는데 있다. 이를 위해 일반고 학생92명과 과학고 학생 57명을 연구대상으로 선정하여 정신용량검사, 산화 환원 개념 검사, 산화 환원 반응식 완결 검사를 실시하고 성취도를 미치는 영향을 분석하였다. 일반고 학생들은 정신용량이 클수록 산화 환원반응식 완결에서의 성취도가 증가하는 경향을 보였으나 과학고 학생들은 정신용량에 따른 성취도 차이가 없었다. 산화 환원개념 이해 정도를 분석한 결과, 일반고 학생들은 개념 이해 정독 전반적으로 매우 낮았으나 과학고 학생들은 비교적 높았다. 일반고 학생들은 개념을 부분적으로 이해한 학생들의 성취도는 개념을 이해하지 못한 학생들의 성취도보다 높게 나타났고 개념을 이해하지 못한 학생들은 정신용량이 클수록 성취도가 증가하였다. 과학고 학생들은 개념 이해 정도가 높을수록 성취도가 높게 나타났다. 산화 환원 개념을 완전하게 이해한 학생은 일반고와 과학고에 관계없이 그리고 문항 유형에 관계없이 높게 성취도를 나타냈음을 알 수 있었다 The purpose of this study was to analyze the influence of mental capacity and understanding of the oxi-dation-reduction concepts on the completion of the balancing redox equations. Participants were 92 senior high school students and 57 science high school students. Tests were conducted to measure the mental capacity, the understanding of the oxidation-reduction concepts and the completion of the balancing redox equations and the influence on the per-formance was analyzed. The performance of the senior high school students increased as the mental capacity increased, but the performance of science high school students did not change by mental capacity. Most of senior high school stu-dents couldn't understand the oxidation-reduction concepts well. Most of science high school students, however, under-stood the concepts completely and partially. The students who had a good understanding of the oxidation-reduction concepts showed a good performance for both senior and science high school students, regardless of the problem pattern.
