This study is to review division of whole numbers which is dealt in the revised elementary mathematics textbook and manual for teacher. The textbook and manual for teachers are most important documents to teach mathematics. And they are important to the would-be teachers who study the elementary mathematics with such documents. Therefore the textbook and manual for teachers should have no errors. But I found they have some errors and problems regarding division of whole numbers. In this paper, I discuss the problems and suggest the alternative plans.

At the Information Age, the significant influence of computer education taking role of computer literacy education as well a information literacy education has been magnified. Since 2000, the 7th curriculum reform has been influenced on Korean education system. Therefore, this paper suggests to implement in textbook duvelopment of cumputer education based on the 7th curriculum reform focused on middle school education. It includes the design of textbook, its contents and organization, various teaching-learning situation method, and evaluation including real situational problems fashioned to the educational paradigm shift.

최근 과학기술(科學技術)의 영향을 받아 급변하는 국내외의 환경을 감안할 때, 과학교육(科學敎育)의 중요성은 심각히 인식되고 있으며 특히 수학교육(數學敎育)은 그 비중이 크다고 할 수 있다. 따라서 수학교과과정(數學敎科課程)의 편성(編成)은 매우 중요한 위치에 있으며 현재 문교부(文敎部)에서도 중(中) 고등학교(高等學校)의 수학교과서(數學敎科書)를 새로이 개편하는 작업을 진행하고 있다. 이러한 국가적으로 중요한 작업이 체계적(體系的)인 연구(硏究)와 제도적(制度的)인 개선(改善)을 바탕으로 이루어져야 한다는 생각 아래에서, 각급학교(各級學校)의 교과과정(敎科課程), 행정(行政) 및 제도(制度), 교과서(敎科書) 집필(執筆) 및 지도평가방법(指導評價方法)에서 나타나는 문제점(問題點)을 파악하고 개선방향(改善方向)을 모색하는 데에 본고(本稿)의 목적이 있다. 수학교육(數學敎育)의 목적을 이해하는 데에는 수학(數學)의 특성(特性)을 파악함이 가장 중요하다고 생각된다. 이 특성(特性)의 근원을 산수(算數)와 기하(幾何)의 발단(發端)에서 찾아보았으며 각급학교(各級學校)의 학과내용(學科內容)을 수학(數學)의 역사적(的) 발전단계(發展段階)와 현대수학(現代數學)의 특징(特徵)에 비추어 분석하여 보았다. 그 결과 각급학교(各級學校) 교과과정(敎科課程)이 일관성있게 배열되지 않은 면이 있고 하위(下位)의 능력평가(能力評價)에 치우친 감이 많아, 다음 단계의 교육에 지장을 초래하면서도 오히려 학생들이 수학(數學)을 어렵게 생각하게끔 만드는 원인들을 찾을 수 있었다. 이러한 문제를 개선하기 위해서는 장기적(長期的) 연구(硏究)를 할 수 있는 전문연구집단(專問硏究集團)과 활성화된 교사(敎師)의 재훈련제도(再訓練制度)의 필요성과 아울러 인시제도(人試制度), 지도방법(指導方法), 평가방법(評價方法)의 개선(改善)이 이루어져야 하겠다.

This study investigated the effect of subject classroom system by examining students' perceptions of science discretion class, which was newly developed as Science Mathematics specialized subject classroom system. Science discretion subject proceeded through inquiry experiments in the subject classroom, applying both block scheduling and divided classes. Surveys were conducted twice in order to find out what the students thought about science discretion subject and subject classroom class. The results have shown that students considered that the teachers have prepared with enhanced enthusiasm and the classes have become more interesting. The satisfaction level for experiment centered subject was very high (84%) and significantly higher in case of science-oriented course students (p<.05) and upper level students (p<.01). In addition, most of the students thought favorably about block scheduling and divided classes.

최근 대학들은 학부제 시행에 따른 학생들의 교과목선택권이 확대됨으로써 수강신청시 학사진도를 강화해야 할 필요성이 대두되고 있으며, 학생들은 자신의 진로에 맞는 좀 더 바람직한 교과목을 선택하고 이수하는데 체계적인 도움을 필요로 하고 있다. 이에 본 연구에서는 학생들이 자신의 목표\ulcorner진로에 맞는 교과과정을 원활히 이수할 수 있도록 도움을 주고자 교과목선정에 대한 상담을 지원하는 지식기반 학사지원시스템을 개발하여 보고자 한다. 개발될 학사지원시스템은 지도교수의 시간부담을 줄이고, 학생들에게는 언제든지 상담을 받을 수 있도록 함으로서 수강신청시 교과목 선정을 보다 효과적으로 지원할 수 있을 것이다.

The purpose of this study was to compare and analyze the cognitive levels of 11th grade students and those required in high school chemistry I textbooks standardized by the 7th national education curriculum. For this study, the cognitive development stages of 456 11th grade students were surveyed using short-version GALT (group assessment of logical thinking). Furthermore, 15 basic concepts were extracted from the contents on water and air, 2 units in chemistry I order to analyze the cognitive levels necessary for understanding high school textbooks, using CAT (curriculum analysis taxonomy). The results showed that 52.5% of the surveyed 11th grade students reached the formal operational level, 28.3% transitional levels, and 19.5% concrete operational levels. 68.9% of the academic high school students and 6.6% of the technical high school students reached the formal operational levels, and the ratio of formation was very different in each logics. As a result of the analyzing the cognitive levels needed for understanding chemistry I textbook contents, in spite of a change in national education curriculum, there were no great change in cognitive levels required by scientific concept except some inquiry activities. The cognitive levels in high school chemistry I textbooks by the 7th national education curriculum appeared higher than the cognitive levels of 11th grade student, but cognitive levels of inquiry activities were similar to the cognitive levels of the students. Chemistry teachers thought of chemistry I textbooks by the 7th national education curriculum as desirable because scientific concepts were reduced and a lot of real life materials were adapted. However, they pointed out a problem of difference in contents levels compared with chemistry I textbooks because scientific concepts were greatly reduced in chemistry I textbooks. The cognitive levels required in chemistry I textbooks still appeared higher than those of the students. Consequently, various teaching and learning methods and materials will have to be developed to be suitable for the students' cognitive levels.

This study analyzed the mathematics textbooks of middle grades in the first Korean curriculum, based on the modern trends of mathematics education curriculum, comparing with present Korean curriculum's other textbooks and the American textbook, MiC. The mathematics textbooks in the first Korean curriculum are based on various situations in our real life and introduce mathematical concepts throughout a set of mathematics problems. The textbooks present mathematical concepts with connected knowledge and include mathematical activities which make students use mathematical table, graph and formula at the same time. And students are actively required to discuss together during the mathematics problem solving process. As the results of this modern review on Korean 1st curriculum and middle grades mathematics textbooks, it would provide preliminary data and meaningful implications for the next curriculum and concomitant instructional materials.

The purpose of this study is to investigate development direction of a mathematics subject classroom. This study started with an analysis of previously conducted studies to investigate. After that, I selected and visited eight schools thatapplied the Mathematics subject classroom for interviews. Observations and interviews with math teachers were executed to figure out circumstances and operational status of the mathematics subject classroom. As the result of this research, the Mathematics subject classroom required various improvements in the facilities and the curriculum systems. Throughout this study, Isuggestedfive principles for teaching and learning. These principles are Creativity, Communication, Cooperation, Mathematical thinking and Problem solving. Furthermore, two subject classroom models for teaching and learning of mathematics - the cooperative learning room and the media room - were designed. These room required different resources and served distinct function.
