고전검사이론과 문항반응이론을 사용하여 2-7차 실험정가 수리영역문항을 분석하였다. 2차부터 7차에 걸친 시험은 피험자에게 너무 어려웠으며 횟수를 거듭함에 따라 점점 더 어려워진 것으로 나타났다. 5차 실험평가 문항분석결과에서 문항 10과 15는 검토가 필요한 문항으로 나타났다. 그리고 7차 실험평가 문항분석결과에서 문항 11과 17은 검토가 필요한 문항으로 나타났다.

본 연구에서는 2004년 11월에 시행된 '2005학년도 대학수학능력시험 수리영역 가형' 의 문항을 분석하였다. 즉, 2-모수 문항 반응 모형에 근거한 베이지안(Bayesian) 1.0을 이용하여 문항의 난이도 및 변별도를 측정하였으며 고전검사이론 프로그램임 테스트안(Testan) 1.0을 이용하여 문항의 신뢰도 및 오답지 매력도를 구하였다. 이 결과는, 학생들이 어느 단원을 어려워하고 어떤 내용을 이해하지 못 하는지 그 원인을 찾을 수 있으므로, 교수-학습의 기초 자료로 활용할 수 있을 것이다.

The purpose of this study is to investigate how the curriculum, in which pre-service teachers experience mathematical process and develop assessment items and standards through the process experience in a mathematical essay course, affects the pre-service teachers and suggest its implications for teacher education. Fourty nine pre-service teachers, registered at a mathematical essay course in a K university in Seoul, developed mathematical essay problems and their assessment standards, and their developed processes were analyzed. According to the analysis results, first, mathematical essay problems developed by the fifty students reflect components of mathematical processes. Especially, one characteristic in revising assessment items shows that pre-service teachers considered not only justification process through different levels of difficulty and mathematical reasoning, but also logical descriptions through problem solving, when they worked on group discussions and examined middle school and high school students' responses. Second, while pre-service teachers developed rubrics for their assessment items and revised the rubrics based on students' responses, they established assessment standards which employed mathematical process by focusing on problem solving process rather than results and considering students' unexpected problem solving. The results imply a concrete method in planning and executing a mathematical essay course which makes use of mathematical process in teacher education.

To provide some suggestions on the setting of mathematics test in the College Scholastic Ability Test(CSAT), this paper analyses the result of mathematics test in the CSAT from 2005 to 2011, on which the 7th national mathematics curriculum has been applied. From the result, four suggestions are drawn out. First, the mathematics test needs to be easier to reduce the burden of test-taker. Accordingly, the number of items and their scores need to be adjusted. Second, the proportion of multiple-choice items has to be reduced whereas that of short-answer items has to be increased to enhance the function of the CSAT as a selection test. Third, the sub-item system needs to be adopted. Fourth, new item-types have to be developed.

This study explored the possibility of building a statistical model predicting difficulty of mathematics test items through the analysis of nation-wide scholastic ability test results for the past 5 years. Multiple linear regression analysis was conducted in predicting difficulty of mathematics test items. We adopted three major areas for independent variables: the content area, the behavior area, and the test item format area, each of which was categorized into more detailed sub-areas. For the dependent variable, the proportion of correct answer was used to represent the item difficulty. Statistically significant independent variables were included in the regression model based on the stepwise selection method. Several important factors affecting difficulty of mathematics test items for each area were identified. R-squares for the final regression model were fairly high, implying that the regression equation can be used to predict difficulty of test items at an acceptable level. Lastly, the regression model was cross-validated using independently collected data. We believe that this study will provide basic but very critical information for predicting the proportion of correct answer by showing the factors that should be considered for developing mathematics test items for the college entrance examination or high school classroom test.

Current mathematics of CSAT(College Scholastic Ability Test) faces time to prepare examination questions according to the new curriculum making this year the last. MEST(Minister of Education, Science and Technology) already decided the range of examination in 2008. However, the discuss about how to construct the questions and what form of questions should be set was not conducted enough. Mathematics items of CSAT will have to undergo changes both in 2012 and 2014. Also, reconstruction of the examination questions for the past 16 years and the exploration of the new direction are strongly required. To accord with these requirements, this study analyze Japan's college entrance exam, NCTUA(National Center Test for University Admissions) which is the most similar to our exams. And then on the basis of this, the applicable implication to set mathematics questions in 2012 and 2014 CSAT will be deducted.

The purpose of this study is to explore the qualitative characteristics of pre-service teachers' motivation while they are participating in group activities for developing mathematical essay assessment problem and revising it. For this purpose, we analyzed individual factors about group learning activities as well as contextual factors about practical competency (in developing and revising mathematical essay assessment problem through collecting data of student responses to the problem). As results of data analyses, autonomy, among individual factors regarding group learning activities, was one of the main characteristics in attainment value, utility value, and intrinsic value, whereas task, authority, and grouping, among contextual factors regarding practical competency, appeared to have a positive impact on task value. These results suggest how to think of specific ideas and articulate them in designing a curriculum to develop student-evaluation expertise for pre-service teachers.
