According to changes of college admission policies and the first application for 2009 revised mathematics curriculum, we should redefine characterization of mathematics section in 2017 College Scholastic Ability Test(CSAT) and prepare a plan on details of making questions related to it. Specially, we need to reflect the voices of the school site in order to determine the method of making CSAT questions which is consistent with the intent of it and contributes to the normal operation of high school curriculum. In this study, we polled out 312 schools among 2,338 high schools nationwide and math teachers of the schools were been chosen were surveyed. The sampling method used a proportionate stratified sampling by the department of education. Analyzing the results of the survey, We redefined characterizations and roles of mathematics section in 2017 CSAT and suggested the details including questions distribution according to optional object of 2017 CSAT mathematics section.

The "Figure Equation" chapter of current high school curriculum prevents students from relating the concept with what they studied in middle school Euclidean geometry. Woo(1998) concerns that the curriculum introduces the concept merely in algebraic ways without providing students with opportunities to relate it with their prior understanding of geometry, which is based on Euclidean one. In the present study, a sequence of GeoGebra-embedded-geometry lessons was designed so that students could be introduced to and solve problems of the Analytic Geometry by triggering their prior understanding of the Euclidean Geometry which they had learnt in middle school. The study contributes to the field of mathematics education by suggesting a sequence of geometry lessons where students could introduce to the coordinate geometry meaningfully and conceptually in high school.

Capacity of making assessment items among teacher's assessment competency is essential element in validity and reliability of assessment. Errors in test items on the formal and content aspects can be a big stumbling block to derive a correct evaluation result. Through this assessment, the positive feedback can not be derived. In this study, By analyzing midterm and final 60 exam papers for geometry and vector in 45 high Schools of Seoul GyeonggiIncheon area, We argue error items and improvements on the formal and content aspect the paper-based assessment of mathematics. Through this, Our intention is to improve the skills of teachers for making assessment items.

This study is to survey and analyze the opinion of teachers about the relevance of educational content in the 7th mathematics curriculum. For the purpose of this study, we analyze the result of the questionnaire survey which consists in the question about the relevance(Quantity, level, validity) of educational content in the 7th mathematics curriculum. 515 elementary school teachers, 314 middle school teachers, and 323 high school teachers are participated in this survey. 75 percent of elementary school teachers think that the educational quantity must be reduced for the relevance of educational content. So do 50 percent of secondary school teachers. Both of them think that the number of topic must be reduced for the relevance. In special, this study shows that the response rate about the object which is related with interest is very low compared with any other mathematics education objects. So, it is necessary to pay more attention to the object which is related with interest.

This study investigated the degree of understanding pre-service teachers' random variable concept, based on the attention and the importance for developing pre-service teachers' ability on statistical reasoning in statistics education. To accomplish this, the subject of this study was 70 pre-service teachers belonged to three universities respectively. The teachers were given to 7 tasks on random variable and requested to solve them in 40 minutes. The tasks consisted of three contents in large; 1) one was on the definition of random variables, 2) the other was on the understanding of random variables in different/diverse conditions, and 3) another was on problem solving relevant to random variable concept. The findings are as follows. First, while 20% of pre-service teachers understood the definition of random variable correctly, most teachers could not distinguish between random variable and variable or probability. Second, there was a significant difference in understanding random variables in different/diverse conditions. Namely, the degree of understanding on the continuous random variable was superior to that of discrete random variable and also the degree of understanding on the equal distribution was superior to that of unequality distribution. Third, three types of problems relevant to random variable concept dealt with in this study were finding a sample space and an elementary event, and finding a probability value. In result, the teachers responded to the problem on finding a probability value most correctly and on the contrary to this, they had the mot difficulty in solving the problem on finding a sample space.

In this study, we identified the elements of teachers'expertise for the science gifted in science high school, and examined teacher perceptions of expertise. Through previous studies and expert consultations, 5 categories such as subject knowledge, inquiry teaching, pedagogical knowledge, student guidance and school work were derived. Based on these 5 categories and sub-element, a questionnaire was constructed. Total 284 mathematics and science teachers from 19 science high schools across the country responded to the survey. The desirable level of expertise and current level of responding teachers' own expertise were examined and compared to each other, and group comparisons were accomplished according to teacher career, type of degree and final degree. Some implications are suggested for the professional development for teachers of the science gifted.

본 연구는 교사양성 대학에 적합한 현대대수학 강좌운영의 실례를 소개하고자 한다. 이를 위하여 군, 환, 벡터공간 내용을 적절히 재구성한다. 갈로아 정리는 고차방정식 근의 가해성과 밀접한 관련이 있으므로 중 ${\cdot}$ 고등학교육과정과도 관련지을 수 있다. 그러나 근론과 환룐, 벡터공간의 이론적 배경을 바탕으로 체론의 갈로아 정리로 나아가는 과정에서 많은 학생들이 어려움을 토로하는 것이 현실이다. 이처럼 그 내용의 중요성에 비해 실질적인 접근의 어려움으로 인하여 체론을 아예 배우지 않거나 배우더라도 그 본질을 이해하지 못하는 경우가 많다. 따라서 본 연구에서는, 교사양성 대학의 학생들의 갈로아 정리의 핵심과 본질을 보다 쉽게 이해할 수 있도록 함에 초점을 두고자 한다.

This study is intended to examine 36 in-service secondary school mathematics teachers' conceptions of proof in the context of mathematics and mathematics education. The results suggest that almost teachers recognize the role as justification well but have the insufficient conceptions about another various roles of proof in mathematics. The results further suggest that many of teachers have vague concept-images in relation with the requirement of proof and recognize the insufficiency about the actual teaching of proof. Based on the results, implications for revision of mathematics curriculum and mathematics teacher education are discussed.

This study aims to identify the effects of teachers' recognition and application of 2015 revised national curriculum on their educational information needs in high schools. Several in-depth interviews and a questionnaire survey with the teachers, who were in charge of teaching common courses, such as Korean language, mathematics, English, social studies, and science, in general public high schools in Incheon, were executed for the purpose. As a result, the teachers' recognition and application affected their educational information needs in part. Especially, new demands on small sized copies and learning information sources were identified which were related to the application of 2015 revised national curriculum. Based on the results, we proposed several improvements of school library operations, such as small sized local consortium for sharing resources and providing referral services, in order to strengthen the gateway role of school libraries.
