  • 수학적 힘의 함양과 문제해결력의 신장을 위한 수학교육에서 확률영역은 중요한 학습소재임에도 불구하고, 확률영역은 어려운 것으로 고착되었다. 이 연구에서는 학생들이 확률영역의 어떤 부분을 어려워하고 이해하기 힘들어하는지를 구체적 문항분석을 통하여 알아봄으로서 교수-학습의 기초자료를 제공하고자한다. 이를 위하여, 지난 10년간 출제되었던 대학수학능력시험의 확률영역 16문항을 고등학교 학생 220명에게 실시하고, 고전검사이론과 문항반응이론울 적용하여 그 결과를 분석하였다. 고전검사이론에서는 신뢰도와 변별도를 측정하였고, 문항반응이론에서는 Rasch 1-모수 문항반응모형에 근거한 BIGSTEP을 사용하여 내적타당도와 난이도를 측정하였다.

  • The purpose of this study was to analyze the characteristics of multiple-choice test items used in assessment of high school integrated science according to 2009 revised curriculum. For the analysis of the tendency of item setting, we devised an analytic framework specific to integrated science, and analyzed the characteristics of items by applying the devised framework and item response theory. The results of the tendency of item setting revealed that most of items run counter to the intent of integrated science in terms of item resource, integration extent, and cognitive level, which means teachers are stick to separative method in teaching-learning and assessment of integrated science. The results of the analysis applying item response theory showed that item difficulty was appropriate and item discrimination was considerably high. However, there was no relevance between the tendency of item setting and qualitative characteristics of the items. We also discussed some agendas to improve the teaching-learning and assessment of integrated science based on the results of this study.

  • PEAS (performance enhancement attitude scale) has been used to measure attitude and disposition toward doping in elite athlete. It is constructed of 17-item, 6-point scale. The purpose of this study was to verify validity of the PEAS for Korean elite player through Rasch model. The scale was administered to 438 Korean elite players. Principal component analysis was used to verify unidimensionality using SPSS program. Rasch measurement computer program, WISTEPS, was used to estimate goodness-of-fit of items and category structure. Differenctial item functioning by gender was also estimated by the WINSTEPS program. All alpha level was set at 0.05. First, principal component analysis showed that unidimensionality is satisfied as over 20.0% of variance of eigenvalue. Second, category probabilities curve showed 5-point scale was better than 6-point scaled statistically. Third, seven items (1, 9, 10, 12, 13, 14, 17) in the 17-item were not good model fit and three items (3, 12, 13) were estimated as the differential item functioning. This study showed that 9-item, 5-point scale is better PEAS to Korean elite player.

  • The aim of this study was to develop scale of test taker to affect on process of selection of college. The study procedures were performed as follow : establish of study model, item generation, verification of content validity, 1st and 2nd pilot test and verification of construct validity and reliability. In order to verification of validity and reliability, 230 freshman were surveyed and the data were analyzed by mean, standard deviation, skewness. kurtosis, Pearson correlation, Verimax factor analysis and Cronbach's ${\alpha}$. As result of factor analysis, the 15 factors(61 items) that explain 68.37% of the total variance were extracted and each factors were classified by attribution as follow : Information collection-mass media(4items), college activity (3items), support and environment(4items), education(5items), Influential person on decision making(3items), education quality(4items), education service(5items), reputation(3items), accessibility(2items), personal circumstances(2items), college's mass media(5items), promotion (4items), on-line(4items), person's PR (3items), College image(10items). Cronbach's ${\alpha}$ of total items was 0.916 and Cronbach's ${\alpha}$ of each factors were showed range between 0.694~0.878. Measurement scale of this study may be utilized to collect basic data be required to establish policy strategy of local college be faced with difficulty of admission recruitment.

  • The purpose of this study was to analyze of the science examination of middle school 7th grade by Klopfer's taxonomy of educational objectives. A total of 645 test items from 10 middle schools were analyzed for this study. The examination items were analyzed according to the objectives of science education, such as behavior and contents area, question types, and the degree of difficulty. It was shown that, when the distribution of behavioral objectives was considered, the items emphasized knowledge and comprehension, and were scientific knowledge oriented. The tests consisted of multiple choice questions at a relatively high rate, compared to short answer questions. Comparing the rate of teachers' expectations to the degree of difficulty, the ratio of "top" was low and that of "medium" was high. The results of this study suggested that using various types of question and multiple levels of content and behavior enabled more effective evaluation of the diverse thinking powers and learning of the students.

  • 대규모 수험자를 대상으로 하는 경우, CBT 방식은 PBT 방식에 비해 비용이나 처리 방법에 있어 효율적이라는 장점을 갖고 있다. 하지만, CBT 평가가 제대로 운영되려면 많은 문항으로 구성된 대규모의 문제 은행이 있어야 하며, 기 구축된 문항은 적합성과 공정성이 반드시 보장되어야 한다. 이에 본 연구는 4,000여 명 이상의 수험자를 대상으로 8000문제가 넘는 문제 은행이 구축되어 실제 CBT 시스템을 개발·운영하고 있는 P 대학교 CBLT 테스트 시스템의 문항들을 분석할 방법을 제안한다. 연구 결과 CBLT 테스트 시스템의 문제 은행의 개별 문항들이 출제자 1인의 주관적 판단에 달려있어 문항에 대한 질 관리가 어렵다는 문제점을 해결하기 위해서는 고전검사이론이 적합하다고 판단된다. 그러나 매 시험이 동질한 문항 세트로 구성되기 위해서는 문항에 대한 충분하고 객관적인 자료가 절대적으로 필요하다. 이를 위해서는 CBLT 테스트 시스템과 같이 응답자 수가 2∼300여 명 전후이며, 40문항의 문항 세트에 대한 분석은 2모수 정도가 적당하다고 판단된다.

  • The purpose of this study was to present improvement directions of college scholastic ability test on industry department. Industry department test were classify and abstracted sampling test on contents and movement domain, analyzed example items of college scholastic ability test on industry department. Research methods used in this study were review of related literature, the item analysis and item pattern analysis between college scholastic ability test on introduction to industry and curriculum, contents of textbook. After finding a problem of developing items, trying to find a solution to the problem and developing an up-to-date method of items was to present improvement. Based on the result of the study, some recommendations for future researches were made as follows: First, a phenomenon of making same contents items over again and no making items not on made the items ever have to cut. Second, Time to read and make sense of items have to reduce because depend on the degree of difficulty related on time to understand of items. Third, the depth of textbook contents has to develop on curriculum this year. Fourth, the succeeding study on linkage between college scholastic ability test and simulation of college scholastic ability test. Fifth, verification validity on contents of new movement domain is developed new and striking test items.
