오늘날 교육현장에서 이루어지는 거의 모든 교육활동은 입시준비와 관련되어있다고 해도 과언이 아니다. 그러나 실제 교육현장에서 이루어져야 할 것은 입시준비를 위한 평가가 아니라 진정한 의미의 학업성취도의 평가분석인 것이다. 본 연구에서는 학생들의 수준을 미리 결정한 후 학습을 진행하게 하는 방법을 지향하고, 학습한 후 학생 스스로가 평가를 통해 자신의 학습 성취도를 평가하고, 다양한 평가분석을 통해 자신의 수준에 맞는 하위 과정의 학습으로 진행하기 위한 방법을 모색하고자 한다. 이에 따라 평가 본래의 목적에 맞게 학습자의 학습 곤란 및 결손을 적절한 시기에 밝혀주고 이를 교정하고 보충할 수 있는 진단평가와 함께 주어진 학습 과제에 대하여 어느 정도로 학습목표를 달성하였는가를 평가할 수 있는 형성평가로 크게 나누어서 각 평가 유형에 따른 적절한 피드백과 함께 상호 작용을 강화할 수 있도록 다양한 분석정보를 제공하는 학습자 중심의 평가 시스템을 구현하고자 한다

eLearning can be defined as an approach to teaching and teaming that utilises Internet technologies to communicate and collaborate in an educational context. This includes technology that supplements traditional classroom training with web-based components and learning environments where the educational process is experienced online. The use of hypertext as an educational tool has a very rich history. The advent of the internet and one of its major application, the world wide web (WWW), has given a tremendous boost to the theory and practice of hypermedia systems for educational purposes. However, the web suffers from an inability to satisfy the heterogeneous needs of a large number of users. For example, web-based courses present the same static teaming material to students with widely differing knowledge of the subject. Adaptive hypermedia techniques can be used to improve the adaptability of eLearning. In this paper we report an approach to the design a unified implementation framework suitable for web-based eLearning that accommodates the three main dimensions of hypermedia adaptation: content, navigation, and presentation. The framework externalises the adaptation strategies using XML notation. The separation of the adaptation strategies from the source code of the eLearning software enables a system using the framework to quickly implement a variety of adaptation strategies. This work is a part of our more general ongoing work on the design of a framework for adaptive content delivery. parts of the framework discussed in this paper have been imulemented in a commercial eLearning engine.

In this paper, we propose the development of Artificial Hippocampus Algorithm(AHA) which remodels a principle of brain of hippocampus. Hippocampus takes charge auto-associative memory and controlling functions of long-term or short-term memory strengthening. We organize auto-associative memory based 4 steps system (EC, DG CA3, and CA1) and improve speed of teaming by addition of modulator to long-term memory teaming. In hippocampus system, according to the 3 steps order, information applies statistical deviation on Dentate Gyrus region and is labeled to responsive pattern by adjustment of a good impression. In CA3 region, pattern is reorganized by auto-associative memory. In CA1 region, convergence of connection weight which is used long-term memory is learned fast a by neural network which is applied modulator. To measure performance of Artificial Hippocampus Algorithm, PCA(Principal Component Analysis) and LDA(Linear Discriminants Analysis) are applied to face images which are classified by pose, expression and picture quality. Next, we calculate feature vectors and learn by AHA. Finally, we confirm cognitive rate. The results of experiments, we can compare a proposed method of other methods, and we can confirm that the proposed method is superior to the existing method.

Teaching with laboratory activities in school science, which are distinctive characteristic, is placed from other disciplines fur teaming almost 200 hundred years ago. A number of science educators have suggested that there are rich benefits in teaming from using laboratory activities. At these time, however, some educators have begun to seriously question the effectiveness and the role of laboratory activities. There are some causes related to obscure and vague aims of laboratory activities. The purposes of this paper is to review aims of laboratory activities presented in the literatures through historical overview, and to obtain implication for school science. There are various aims of laboratory activities by a number of researchers. Overall synthesizing, there are ffur domains of aims of science teaching through laboratory activities, (a) science knowledge has two sub-domains; scientific content knowledge and procedural knowledge, (b) nature of science, (c) science attitude has two sub-domain; scientific attitude and attitude toward science, and (d) ability of scientific inquiry has two sub-domain; manipulative skills and scientific thinking. But, it is necessary to continue the following study in order to obtain the aims of laboratory activities agreed by expert community, and setting up of lists of aims of laboratory activities for students to achieve hierarchies of school science curriculums.

Emergent computing paradigms such as genetic algorithms have found increased use in problems in engineering design. These computational tools have been shown to be applicable in the solution of generically difficult design optimization problems characterized by nonconvexities in the design space and the presence of discrete and integer design variables. Another aspect of these computational paradigms that have been lumped under the bread subject category of soft computing, is the domain of artificial intelligence, knowledge-based expert system, and machine learning. The paper explores a machine learning paradigm referred to as teaming classifier systems to construct the high-quality global function approximations between the design variables and a response function for subsequent use in design optimization. A classifier system is a machine teaming system which learns syntactically simple string rules, called classifiers for guiding the system's performance in an arbitrary environment. The capability of a learning classifier system facilitates the adaptive selection of the optimal number of training data according to the noise and multimodality in the design space of interest. The present study used the polynomial based response surface as global function approximation tools and showed its effectiveness in the improvement on the approximation performance.

The purpose of this study was to examine how environmental education teachers think about environmental teaching materials of their use in primary and secondary schools. For this purpose, six primary and secondary school teachers were selected for focus group discussion on October 17th, 2005. The discussion of focus group was recorded both on video and audio tapes. Teachers' discussion could be analyzed in the perspectives of two big ideas, 'content selection' and 'content organization and presentation'. The big ideas were categorized into several areas: 1) The idea of 'content selection' was classified into 4 areas such as integration, difficulty level, locality, and timeliness, 2) The idea of 'content organization and presentation' was classified into 4 areas such as learning motivation, teaching and teaming strategy, evaluation method, application of teaching materials. This study provided meaningful ideas, which can be used in developing environmental education materials as well as effective teaching and teaming strategies for school environmental educators.

So far, the graphics of Korean clothing have focused on maintenance of forms without specific improvement. In particular, in the archetypal design of a Jeogori, ambiguous standards on the overlapping of left and right collars and collar strips cause problems in the teaching and teaming of Korean traditional clothing. As a result, the graphics of men's Durumagis based on a Korean Jeogori have the same problems as Jeogoris and the connection between them has not been sufficiently studied. Design of "Moo" in respect to graphics of men's Durumagis has its own calculation equation or measures, but they can not be generalized. This study therefore considers the existing graphics of men's Durumagis or approaches of Moo in different angles by reviewing the connection between Durumagis and Jeogoris. Therefore, archetypal forms of Durumagis are designed with a radius of a circle using one's height and the girth of one's chest, which contributes to symmetry of the collars and teaming effects through scientific graphics of "Moo." It is further expected that can be mass-produced through archetypal design of overcoats and graphics of "Moo" of Durumagis that can be standardized as well as connection between graphics of Jeogoris and Jeogoris.
