임현선(Hyun-Sun Lim),이영미(Young-Mee Lee),안덕선(Duck-Sun Ahn),이준영(Joon-Young Lee),임 형(Hyung Im) 한국의학교육학회 2007 Korean journal of medical education Vol.19 No.3
Purpose: The objectives of this study were: 1) to analyze Clinical Performance Examination (CPX) items using item response theory (IRT) and classical test theory (CTT) and 2) to discuss how to apply and interpret these results in order to improve the quality of CPX items. In addition, we intended to explore statistical procedures in order to merge examination data from several different medical schools. Methods: The subject of the study was the 2005 CPX examination data from 10 medical schools located in Seoul and the Kyunggi province. For merging data from ten different medical schools, Levene s test for homogeneity of variances was used. Homogeneous group selection was conducted based on ANOVA or Kruskal-Wallis test and Tukey s multiple comparisons appropriately. The generalized partial credit model was applied to analyze polytomous items and the 2-parameter logistic model was used to analyze dichotomous items. Results: Data from 8 medical schools were incorporated into the analysis. The result of the discrimination index by IRT was different from that of CTT in both polytomous and dichotomous items. Discrimination index from IRT tended to be lower than that of CTT. Difficulty index of dichotomous items of two models was correlated well with each other. However, for polytomous items, IRT model provided more information than CCT. Conclusion: We discovered that the CPX items were mostly easy in terms of difficulty index, and the result from IRT and CCT model did not correlated well in the discrimination index. IRT may provide more detailed information for polytomous items, but the checklist and criteria of scoring system should be cautiously reviewed.

권오남,박경미,임 형,허라금 이화여자대학교 사범대학 교과교육연구소 2001 교과교육학연구 Vol.5 No.2
이 연구는 고등학교 학생들의 계열 선택 양상 및 계열 선택에 영향을 주는 요인에 있어서 성별간에 유의한 차이가 있는지를 알아보기 위한 것이다. 그 결과 자연계열을 선택하는 데 있어 남녀학생에게 조건의 차이가 있음이 발견되었다. 여학생은 자신의 능력과 적성에 상당한 확신을 가지고 있거나 부모님의 기대에 따라 자연계열을 선택하는 반면, 남학생은 직업을 포함한 사회적 조건들을 복합적으로 고려하여 선택하는 경향이 있었다. 이러한 계열 선택에서의 남녀 불균형 문제는 우리 사회 문화 전반적 맥락에 걸쳐있으며, 이를 줄이기 위해서는 여학생에게 직업에 대한 의식을 강화하는 교육이 필요하고, 전통적인 성 역할 고정관념을 깨는 부모교육이 필요하다. In spite of women's increasing enrollment in higher education, women have been concentrated on female-dominated majors which do not require mathematical backgrounds, whereas men have been concentrated on science, engineering which require mathematical background. This study investigated highschool student's choice of curriculum which is based on math and science. The participants of this study were high school students in Seoul. Data were collected by the questionnaire which includes questions on preference of subject matter, career plan, conception of sex differences and demographic factors. Female student who chose the curriculum which was based math and science tended to have strong confidence about their aptitudes, whereas male students who chose the curriculum which was based on math and science tended to have occupational aspiration of their careers. This study suggests policy implications intervention programs which encourage girls‘ better achievement and pursue careers in math.

고등학교의 시설 및 교원조직 운영 실태: 공학과 별학 간의 비교
권오남,곽삼근,임 형,허라금 이화여자대학교 사범대학 교과교육연구소 2001 교과교육학연구 Vol.5 No.2
남녀공학 교육형태가 세계적으로 확산되는 추세 속에서 우리 나라 공학 교육은 실질적인 양성 평등교육에 대한 충분한 사전 준비 없이 확대·시행되고 있다. 이러한 상황에서 공학교육의 실태와 문제점을 양성평등의 실현이라는 차원에서 분석해 보고자 한다. 성별 학교 유형에 따른 학교 운영상의 차이점을 파악하기 위해 남녀공학, 여학교, 남학교의 학교 운영 실태 및 시설현황을 분석해 본다. 연구 방법은 서울, 대구, 경기, 전북, 제주의 일반계 고등학교를 대상으로 1·2차의 수정작업을 거쳐 개발된 설문지를 사용하여 연구를 수행하였다. 연구 결과에 따르면, 의사결정직의 구조에서 상위직의 여성의 비율이 남녀 공학과 남학교에 비해 여학교의 경우에 상대적으로 높게 나타나고 있으며, 계열별 주요 교과 교사의 성별 분포에서는 인문계 교과에서 여교사 비율이 높게 나타나고 있음을 알 수 있었다. 이러한 인문계 영역의 여성의 편중 현상은 인문계 계통의 대학에 여학생의 진학 비율이 높게 나타나고 있는 데에서도 보여지고 있다. 또한 연구결과를 살펴보면, 교복 착용이나 교훈 등에서 여학생의 활동을 제약하는 요소들을 내재하고 있는 것으로 밝혀졌고, 시설물도 부족하게 제공받고 있음을 볼 수 있었다. 학교의 운영체계는 학생들에게 역학 모델로서 큰 영향이 미칠 수 있다. This study attempted to compare co-educational and single-sex Korean high schools in terms of their facilities for each gender and organization of teachers for decision-making processes. The subjects of this study were 43 high schools in Seoul, Daegu, Kyonggi, Chonbuck, and Cheju areas. Data were collected by the questionnaire which includes questions on gender distribution of teachers for decision making processes, educational golas, school facilities for each gender, and others. The percentage of male teachers involving decision-making processes was higher than that of females teachers in both co-educational high schools and single-sex high schools. Further, this study revealed that girls were lacking for school facilities such as playground, toilets. This study suggested that teachers, educators, policy makers should aware of these facts in order to achieve gender equity and equality in high schools.

Purpose: Since 2000, the Korea University Medical College has conducted Comprehensive Basic Medical Sciences Examination as a summative test. Summative assessment must be dependable in that it meets the highest standards of reliability and validity. The purpose of this study were to examine the validity and reliability of Comprehensive Basic Medical Sciences Examination and to improve the quality of the examination. Methods: The subject of this study was the examination materials and scores of the test. We conducted exploratory factor analysis to testify validity. Cronbach α coefficient was used to examine the reliability. Results: Only one factor was extracted from exploratory factor analysis. Its eigen value was 4.61 and it explained 65.93% of total variance. We could infer the extracted factor as an ability of basic medical sciences knowledge. The reliability coefficient of the test was ranged from 0.45 to 0.74. Of the total 335 item, overall acceptable items were 206 (58.0%); the range of difficulty was 0.21~1.00 and discriminative indices were higher than 0.20. Conclusion: We confirmed the Comprehensive Basic Medical Sciences Examination in 2000 met the relative highest standards of reliability and validity. Item analysis could be of help to improve the quality of examination
