To solve modern social problems, it is important that improve the democratic citizenship quality of people. This quality includes the rational and democratic problem-solving capacity, decision-making capacity, democratic skills and attitudes such as human dignity, dialogue, compromise. To use an educational network simulation game that has the merits of game, simulatio and network will help children to improve the democratic citizenship educaiton. This study explorers the structure, flow, system, database, interface and teaching-learning tool for this educational network simulation game.

The purpose of this paper is to evaluate the computer education experience of high school graduates that were taught under the 7th curriculum and present insight into the making of required courses for college. To achieve this purpose questionnaires were given to college freshmen to fill out about computer education performed not only during middle school, but also outside of the classroom. For suggestions towards computer courses for college students, how students are being taught the use of computers, how students are using computers, and the computer proficiency of the students were assessed.

Emthusiasm about the introduction of computers into mathematics education is widespred. But, the perspectives about the relationship between mathematics education and computer are diverse. The purpose of this study is to examine theoretical background for using computers in mathematics education. In spite of the pedagogical possibilities of computers. only a small minority of mathematics teachers are using computers in mathematics classroom. It is natural to seek this obstacles within theoretical background of the teachers who manage computers, In this study, We discuss the problems in the two sides. First, due to increased computer activity, relationship of mathematics in school with mathematics in society is changing. It is tension between academic mathematics and practical mathematics. School mathematics have to be changed toward stressing practical mathematics. Second problem is the dialectical relationship between the individual and the collective. While maintaining a respect for the individuality of student contributions. We take into account the social dimension of mathematical meaning-making. We discussed theoretical clarification of work collaborative learning. We propose the case study for the roles of computer in collaborative mathematics learning.

Recently, the tendency for young people losing interest in science has accelerated. This tendency is remarkable for not only Japan but also some countries of Asia. It is thought that this tendency was brought from the decrease of the chance to watch the actual manufacturing activities, and the decrease of the real experience which children makes something in their childhood. In order to bring up the capable engineers on such a social background, making a product practice which promotes the understanding of the application of theory for manufacturing products is important in addition to study by the text book. In this study, some practical work materials for the lower grades in the college were developed. Integration of the developed materials and the course of study becomes an effective teaching method of the of subjects on a special field. Arranging this practical work on the learning process makes a high effect of the integrated practical work on the curriculum.

Modern warfare has developed into a network based simultaneous and integrated warfare where operations elements are interconnected. Following such change in modern warfare, ROK Army has been making an effort to transform personnel-based military structure into technology-based advanced structure. Considering technological innovations and changes in characteristics of officers and men, ROK Army is developing scientific education and training system to provide demand-focused customized education. To support such transformation in education and training, ROK Army is constantly developing Army training system using advanced M&S technology. This paper describes ROK Army's education and training policy, and elaborates the current status of M&S training system using advanced M&S technology. This paper further discusses the future directions of M&S training system.

The purpose of this study is to search for the effective way of development in managing Open Education Schools by analyzing obstacle reasons for school management of elementary school teachers on the basis of classroom site. This study researched 240 teachers and head teachers in three cities and counties of Chungbuk province through questionnaires which enquire obstacle reasons for Open Education. This research regarded 9 items including curriculum management and teaching method as main factors for consisting of Open Education School. And this analyzed the reactions from the percentages of interviewees. As a result of this analysis. obstacle reasons are as follows. 1. priority for academic background and the lack of school facilities and materials. 2. deficiency of teachers' belief in Open Education and unskilled practice. 3. closed situation in decision making and communication. 4. unreasonable management of finance and school facilities.

The solvolyses of anthraquinone-2-carbonyl chloride (1) were studied kinetically in 27 pure and various mixed solvents. The analysis using the extended Grunwald-Winstein equation in the solvolyses of anthraquinone-2-carbonyl chloride (1) obtained the l value of $2.11{\pm}0.11$, the m value of $0.54{\pm}0.06$, and the correlation coefficient of 0.955. The solvolysis reaction of 1 might proceed via an associative $S_N2$ mechanism enhancing bond making than bond breaking in the transition state (TS). This interpretation is further supported by a relatively large solvent kinetic isotope effect (SKIE, 2.27).

Teaching of fractions is very challengeable for elementary and middle school teachers. Many teachers feel uncomfortable teaching the subject. How shall we introduce the concept of fractions? Shall we focus more on concept development or computational procedures and skills? What methodology can be used in teaching those important topics? These are the kind of questions many teachers and researchers try to answer. In this article, the authors are to look at this issue from a cross nation perspective, by examining how the Chinese mathematics curriculum and the Chinese teachers deal with this subject.

In this study, we will develop and implement the teaching program of 'Function', on the subject of "Poster-Making utilizing the Graph Art" in the Math Camp for middle-school students. And we will examine the didactical significance through student's activities and products. The teaching program of 'Function' utilizing the Graph Art can be promoted self-directly the understanding of 'Function' concept and the ability for handling 'Function'. In the process of drawing up the graph art, in particular, this program help students to promote the ability for problem-solving and mathematical thinking, and to communicate mathematically and attain the his own level. Ultimately, this program have a positive influence upon cognitive and affective and areas with regard to mathematics.
