The development of information and communications technologies(ICT) is changing school education, which is a center of teaching/lession process. Information and communications technologies can not guarantee quality education appropriate for knowledge & information society. Interactions between ICT and educational environment, change in the role of teachers, and shift in teaching strategies for educational contents and learning method would be required. This paper has studied the relationship between school education and ICT, change in the role of teachers, and a direction in teaching strategies to take advantage of ICT in school education. For this purpose, it has endeavored to offer an ideal ICT environment by researching both some cases in the foreign countries and the seventh educational process in Korea. In conclusion, this study recommends the followings; First, interactive environment between school and ICT is necessary to make education appropriate to knowledge-information society; Secondly, in the structutive teaching/learing process based upon ICT classroom, teachers should not be the old role player, such as knowledge transfer and learning manager any longer; instead, they should stimulate more social and conversational thinking, and integrate ICT into teaching process; Thirdly, teaching strategies need to change for the purpose of promoting evaluative thinking productive thinking creative thinking.

According to this recent change of the educational stream, the researcher sought to find the relationship between the level of students' Self-Regulated Learning and the Knowledge Construction Process strategies they use to succeed at an educational on-line game, and attempt to make some suggestions on the design and use of educational on-line games in this study. In conclusion, the change in the education paradigm requires students to pursue and produce contextual knowledge by using various media and learning environments. Some theoretical backgrounds, related to situated learning theory and the use of supporting educational media, are necessary. As contextual educational media, On-line games can be expected to play the role of evoking fresh perspective towards all the aspects of education.

Beyond the simple stage of technical development, the growth of information networks have changed areas such as the economy, communities, and education. Existing knowledge and new knowledge about these things have developed and either coexist or conflict with each other. It is difficult to predict the result of this interaction since old and new information is changing so quickly. The transition from a simple communication to an interactive communication is related to a changed communication environment which involves a more complex level of understanding. Establishing the new design concept which is aimed at the future and developing new educational programs which respond to these new information networks are important in order to educate designers who can adjust to the new information network era and construct design education. This paper reports research about the process of developing new education systems that explore the new design paradigms, the changing information network, and the proper approaches to developing design education programs which fulfill these requirements.

의미적 지식기반인 온톨로지(ontology)에 대한 관심이 높아지고 있다. 온톨로지란 어휘나 개념의 정의 또는 명세로서, 인간과 컴퓨터의 의사소통 또는 지식의 표현과 저장, 활용 및 재사용을 위해 이용된다. 그러나 온톨로지를 구축하는 대부분의 방법은 체계적이거나 자동적이지 못하다. 도메인 전문가에 의존하는 전통적인 온톨로지 구축 방법은 시간과 비용이 많이 소요된다. 온톨로지 구축 툴은 많이 있지만 아직 인간의 노력을 필요로 한다. 또한 변화하는 도메인 지식을 온톨로지에 신속하게 반영하는 것은 어려운 일이다. 본 연구는 이러한 한계를 해결하기 위해, 도메인 전문가의 지식이나 경험을 최소화하면서 자동적으로 도메인 지식을 얻을 수 있는 방법을 제시하였다. 이 방법은, 데이터 기반의 도메인 지식을 대상으로, 베이지안 망(Bayesian network)이 갖고 있는 데이터 분석에서의 장점과 온톨로지와의 관련성을 이용하여 온톨로지를 자동적으로 구축하는 것이다. 평판(flat panel) TV 경기예측 사례를 통하여 온톨로지를 구축하는 과정을 알아보았다. 구축과정의 타당성을 확보하기 위하여 디스플레이 산업 전문가들과의 인터뷰를 통하여 온톨로지를 완성하고, 해당 온톨로지의 타당성 검증을 위하여 멤버체크를 한 결과 매우 높은 타당성을 얻을 수 있었다. 본 연구에서 제안하는 온톨로지는, 실제로 산업경기 예측을 계획하고 구축하며 미래 의사결정지원시스템을 설계하기 위한 주요 구성요인으로 제공될 수 있을 것이다.

This study offered lexical knowledge acquisition model of unsupervised learning method in order to overcome limitation of lexical knowledge hand building manual of supervised learning method for research of natural language processing. The offered model obtains the lexical knowledge from the lexical entry which was given by inputting through the process of vectorization, clustering, lexical knowledge acquisition automatically. In the process of obtaining the lexical knowledge acquisition of model, some parts of lexical knowledge dictionary which changes in the number of lexical knowledge and characteristics of lexical knowledge appeared by parameter changes were shown. The experimental results show that is possibility of automatic building of Machine-readable dictionary, because observed to the number of lexical class information cluster collected constant. also building of lexical ditionary including left-morphosyntactic information and right-morphosyntactic information is reflected korean characteristic.

The purpose of this study is to investigate the relationship between the distance function average speed and the speed function. Particularly, in this study, we investigate the process of constructing the speed function in the distance function (irrational function, exponential function) which is difficult to weaken the argument in the denominator. In this process, students showed various anxieties and expressions about the procedural knowledge that they constructed first. In particular, if student B can not explain all the knowledge he already knows in this process, he showed his reflection on the process of calculating the differential coefficient. This study adds an understanding of the calculation method of students in differential coefficient learning. In addition, it is meaningful that the students who construct procedural knowledge at the time of calculating the differential coefficient have thought about how to provide opportunities to reflect on the procedure they constructed.

The purpose of this study is to build an instruction method focused on the mathematical process and apply it to 12, 5-year-olds from Kindergarten located in Seoul with a view to explore the changes in their mathematical thinking. In addition, surveys with parents and teachers, as well as those conducted in the field of early childhood education, were conducted to analyze the current situation. The effects focused on the five mathematical processes, namely problem solving, reasoning and proof, connecting, representing and communication was found to help the interactions between teacher-child and child-child stimulate the mathematical thinking of the children and induce changes. The mathematical process-focused instruction aimed to advance mathematical thinking internalized mathematical knowledge, presented an integrated problematic situation, and empathized the mathematical process, which enabled the children to solve the problem by working together with peers. As such, the mathematical thinking of the children was integrated and developed within the process of a positive change in the mathematical attitude in which mathematical knowledge is internalized through mathematical process.

인간이 생각하고 지식이 습득되어지는 방법에 대한 이해는 인지과학자들에게 항상 중요 관심사이다. 학교교육이 전개된 후의 학생들을 대상으로 한 인지과정을 탐구하는 것은 쉽지 않다. 본 논문에 유아기 유아들을 대상으로 과학적인 표상능력을 이용하여 유아의 인지구조를 고찰하였다. 5세 유아 120명을 대상으로 2년간 주변에서 흔히 볼 수 있는 곤충류를 관찰할 수 있도록 한 후, 그림 그리기와 언어 표현 방법을 이용하여 유아들의 인지과정이 탐구되었다. 유아들은 1차, 2차 표상과정을 통해 기존에 갖고있던 사물에 대한 개념에 분명한 변화를 보였다. 본 연구결과는 유아들의 과학지식 형성에 대한 인지과정을 기술하며, 과학적 지식으로 확장될 수 있는 효율적인 지도 방법을 제공한다.

Collaborative knowledge is continuously producted and modified by group individuals during collaboration and it is also fostered in a radical trust environment like Wiki. The example is Wikipedia. However I found out a big problem as difficulties of exploring when the knowledge space is extended more and more widely. To solve this problem, collaborative knowledge management systems are implemented based on wiki. The one is navigation map that supports the efficient exploring and the another is knowledge map that supports a convergent thinking in a group. In this study, we examined the effectiveness of navigation map and knowledge map.
