This study investigated the trends in the number of applicants and mean score and applicants' responses on the test items of 'science inquiry' of the College Scholastic Ability Test(CSAT) implemented for 3 years$(1999\;{\sim}2001)$. The results of this study were as follows: The percentage of applicants of science track for 1995 CSAT were 43.13%, but reduced to 29.5% for 2001 CSAT. And unlike other tracks, the percentage of male applicants, ranking above average, of science track was 65.58%, which is about twofold of female applicants(34.42%). The mean score of 'Science inquiry' was 58.6 in 1999, and 69.5 in 2001. And the score of the applicants, ranking above average, of humanity and social science course and science course, were 85.8 and 90.7 respectfully in 2001 CSAT. These high mean scores were caused by the policy of "easy CSAT" so called. Most of test items were developed to have difficulty 60-79% or above 80%. This easy CSAT provoked intense dispute about the discriminating power of CSAT. The mean score of male applicants was higher than that of female. But the difference decreases every year. Applicants were generally very good at solving tests focusing on process skills only but poor at solving tests related to physics or calling for two or more science concepts. Thus special measures to cope with the decrease in applicants, especially female applicants, for science track should be provided. To increase discriminating power of CSAT, it is recommended to develop test items with wider range of difficulty and to reduce test items which are focussing process skills and can be solved without any special science concepts. And special consideration should be given to teaching the content area with poor achievement and high actual difficulty compared to the expected.

The study aimed to compare and analyze Nuri curriculum and contents for mathematics in Korea and the Common Core State Standards(CCSS) and New Jersey Preschool Standards for mathematics in the United States. With the results as basis, this study intended to provide suggestions and directions for improving Nuri curriculum of mathematics for young children. For the goal of this study, educational goals, categories of contents, and specific contents were reviewed. First, results of this study indicated that Nuri curriculum for mathematics provides comprehensive educational goals that promote problem-solving ability in everyday contexts with composing mathematical knowledge. On the contrary, CCSS and Preschool Standards provide specific educational goals that focus on children's mathematical skills and concepts. Second, the contents of both countries' curriculum concentrate on 'counting and cardinality', 'measurement', and 'spatial and geometric sense.' There are 5 categories of CCSS, 4 categories of Preschool Standards based on CCSS and one category of Nuri curriculum for mathematics. Third, there are the differences between the two countries' curriculum in continuity from kindergarten to first grade and description method for curriculum.

The purpose of this study is to draw implications for the improvement in the CSAT by analyzing structures and tasks in the Abitur. To this end, it analyzes the mathematics test system with a focus on the basic and advanced level examination systems, the operator, the using technology, and mathematical formulas. And the characteristics of tasks in the 2021 Abitur were analyzed. As a result of the analysis, first, Germany evaluates whether students have the competency emphasized in the curriculum at Abitur. Second, Germany, which emphasizes the proper use of technology, utilizes both tasks that use technology and those that do not in the Abitur. Third, the Abitur consists of most of the tasks using promised operators and uses various types of operators to present various types of questions to evaluate competence. Fourth, the Abitur includes not only simple structured items consisting of 2-3 subtasks but also tasks dealing in depth with a single situation centered on a big idea. Finally, mathematical justification and proof play an important role in the Abitur. Based on this, some specific measures for improving the CSAT were suggested.

This Paper reports results of investigating the relationship between students' perfoonance and mathematics imtructiooal system in understanding of the function concept. A written examination measuring calcullli students' understanding of the fimction concept was administered to two groups of students whose educatiooal oockground were different. One group consists of students who completed a pre-calculus course in Korea and the other group completed the same course in the United States. This study investigates how students in two groups acquire an understanding of major aspects of the function concept and provided interesting insights regarding the different background and belief related to their performance. Follow-up interviews were conducted to identify possible explanations for the different performance of the two groups in understanding the function concepts. Results indicate that the differences came from the educational environment and individual belief.

The purpose of this study was to understand the perception of professors and students about non-face-to face classes at the university. The subjects of this study were 194 professors and 1,543 students at M University. In addition, 23 mathematics majors and 80 students of natural sciences and engineering investigate the perception of using video contents methods. It surveyed the evaluation from students after progressing online classes using video for one semester. The results of this study are as follows. First, the students preferred distance education type was an audio recording using lecture materials or class video contents. Second, an online class using video content was preferred by the students who are well self-control or have an autodidactic background. Finally, professors advanced preparation and careful consideration for the students enhanced the course satisfaction of students.

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.

The purposes of this study are to analyze the higher education admission policy of France and to draw policy implications for Korea. For this study, literature reviews and interviews (face-to-face, email, telephone) were adopted for main research methods. The major findings were as follows: First, baccalaur?at diploma is necessary for higher education admission in France but each higher education has different admission policy according to their legal status. University has open enrollment policy and has no student selection process. Other higher institutions such as grands ?coles select students based on students' academic achievements. Second, baccalaur?at is national diploma which shows successful conclusion of the upper secondary education and gives right of access to higher education. This diploma is awarded to candidates who have passed a series of standardized written and oral tests drawn up at national level (10/20points). Third, students' academic achievements in high schools are major criteria for admission for higher institutions which has student selection process. Fourth, entrance exams implemented at college level are various according to higher institution. Last, 'Admission Post-bac-APB' site is used to support and facilitate the whole admission process. Based on these findings, several policy implications were suggested.

This study investigated Korean science teachers' concerns and needs regarding inquiry testing to cope with the innovation called College Scholastic Abilities Test(CSAT), which was officially first administered as the nation-wide college entrance exam in 1994. This study adopted Concerns Based Adoption Model(CBAM) as the theoretical framework developed by Hall et al. 60 high science teachers (30 physics, 20 earth science, 10 others) were involved for the main study in August, 1992. In general. science teachers demonstrated a concern profile similar to that of 'nonusers'. They showed high level of concerns on the 'information' and 'personal' stage, while low level of concerns on 'management' and 'consequence' stage. Science teachers expressed their strong needs for knowledge and support to facilitate inquiry teaching and testing, text books written in inquiry mode. It is recommended that in-service trainings be provided based on the concerns and needs of teachers for a better teacher training and successful implementation of the innovation.
