As the society evolves into information age, new teaching and learning methods are proposed. In this paper, we design and implement an on-line quiz program for the formative evaluation of Distance Computer Education. The computer studies include many difficult concepts and those are hard to learn and the distance learning has the advantage of overcoming time and spatial limitations but it needs learner's strong motivations to study. Also, the formative evaluation may guide teachers and learners to studying course and it is necessary to prevent both users from too much load. Therefore, presenting quiz and solving it may be a better way for the formative evaluation and we design and implement a Quiz Program for the formative evaluation of Distance Computer Education. We believe that our program will improve motivation of students in Distance Computer Education

In this paper, we propose a system to a criminal profiling simulation training and assessment with virtual reality technology. Profiling has emerged as the incidence of violent crime has increased by 45.2 % in the country over the past decade. However, the number of profilers in Korea is 36, due to the problem of existing courses. "Criminal Reproduction Learning" is the common way to profiling training, but there are numerous constraints that prevent practical training. Thus, the system used virtual reality technology to overcome existing constraints. Users can receive simulation training and assessment of profiling at crime scene that have been implemented as virtual reality, with an immersive experience through interaction. We expect this system to contribute to the activation of profiling education in many institutions and to the development of good profilers with diverse training.

Computational thinking is complexity and independent subject matter being capable to learn concept of computer science and providing methodology of problem solving. Also many experts have said that computational thinking will be grow essential tool in the further developing information society. Thus our country has been trying to introduce it in the K12 informatics subject matter education. Therefore we proposed a introducing method of computational thinking being appropriated of a character of it in the informatics curriculum. To do this, we analyzed character and worthy of it, advanced model cases introducing it into the curriculum. And we proposed that introduced case of it into curriculum is divided 3 cases archiving computational thinking itself, being connected aim of general subject matter with it and computer science education. According to this advanced cases, this study selected permeative style of computational thinking with the informatics subject matted curriculum. This method is divided achievement criterion into contents and means. also we proposed that contents area of informatics subject matter achievement criterion is composed Computing System, Information Life, Software and means area can be filled with subset of computational thinking. This introducing method can make informatics subject matter education settle subject matter helping problem solving through computer system beyond character of technology oriented subject matter.

Linked Data is about using the web to link related data that wasn't linked previously. To publish linked data, people should be able to represent, share, and link pieces of data, information, and knowledge by using URIs and RDF. However, building linked data is not easy for the common users who do not know the knowledge or skill about using URIs and RDF. In this paper, we present a system that the common users can create linked data by connecting data originated from different RDFs. They build linked data by adding new links to connect between RDF data saved in their computers or searched from Swoogle. We can apply the proposed system to creating educational contents. For example, teachers can develop various learning contents by building linked data that connects different data suited to the learning level of their students.

일선현장에서 사용되는 웹기반독서교육시스템은 웹의 다양한 장점을 토대로 학습자들의 흥미와 상호작용을 이끌기 위해 주력하였다. 그러나 실제로 학교 현장에서 독서활동이 주로 종이책을 중심으로 온라인 상에서 이루어졌기 때문에 웹기반독서교육시스템은 아동들의 독서활동과 직접적으로 관련시키기가 어려워 주로 독후활동 중심으로 활용되어왔다. 또한 온라인 독서를 할 수 있는 전자도서는 그 자체가 특정 포맷을 토대로 별도의 다운로드를 통해 책을 읽도록 되어 있어 독서 활동으로만 끝나는 경우가 많아 독후활동이 제대로 되지 않는다. 본 논문에서는 웹기반 독서 교육 시스템을 전자도서와 연계하여 아동이 컴퓨터로 책을 읽음과 동시에 독후활동도 병행할 수 있는 방안을 제안하고자 한다.

전자도서관과 LOD 기술을 접목한 웹기반 교육 시스템의 연구는 몇 년 동안 활발히 진행되어 왔다. 특히, 멀티미디어 기술 및 컴퓨터 통신 기술 개발의 가속화 및 이을 응용한 컨텐츠 개발에 촉진제 역할을 하게된 웹의 탄생은 교수-학습 활동에서의 교육형태로 인식할 수 있는 전환점을 제공하게 되었고, 웹을 기반으로 한 교육(WBI: Web-Based Instruction)이라는 새로운 교수 모형이 제시되기에 이르렀다. 또한, 최근에 학습자의 요구에 맞는 코스웨어 주문이 증가되고 있는 추세이며 그에 따라 웹 기반 교육 시스템의 효율적이고 자동화된 교율 에이전트의 필요성이 인식되어 있다. 그러나 현재 연구되고 있는 많은 교육 시스템들은 학습자 성향에 맞는 코스를 적절히 서비스 해지 못할 뿐 아니라 지속적인 피드백과 학습자가 코스를 학습함에 있어서 취약한 부분을 재학습 할 수 있도록 도와주는 서비스를 제공하지 못하고 있다. 본 논문에서는 학습자의 학습 모니터링과 지속적인 학습평가에 의하여 개인 학습자의 학습 성취도를 계산하여 학습자에게 적합한 코스 스케쥴을 제공해 주는 코스 스케쥴링 멀티 에이전트를 제안하고자 한다.

인터넷 환경 아래에서 멀티미디어 매체 및 컴퓨터 통신 기술의 발전은 사회전반의 변혁을 가속화하게 되었다. 교육에 있어서도 수동적인 자료 중심으로 상호작용하고 시간과 공간을 초월하는 새로운 구조에 대한 연구가 활발히 진행되어 왔다. 새로운 교수-학습 활동의 형태로 웹을 기반으로 한 교육(WBI : Web-Based Instruction)이라는 모형이 제시되고 있다. 또한, 학습자의 필요에 응하는 코스웨어의 제공이 요구되고 있으며 이에 따라 웹 기반 교육 시스템에 효율적이고 자동화된 교육 에이전트의 필요성이 인식되고 있다. 그러나 현재 연구되고 있는 많은 교육 시스템들은 학습자가 원하는 코스를 적절히 제공하지 못하고, 계속적인 피드백과 부족한 부분을 적절히 반복 학습할 수 있도록 인도하지 못하고 있다. 본 논문에서는 학습자의 성취도 생성 알고리즘을 이용한 코스 스케줄링 멀티 에이전트 시스템을 설계하고 구현함으로써 보다 효율적인 학습을 유도한다. 제안한 시스템은 학습자의 학습활동을 지속적으로 모니터링하고 평가하여 개인 학습자의 학습 성취도를 계산하며, 이 성취도를 에이전트의 스케줄에 적용하여 학습자에게 적합한 코스를 제공하고, 학습자는 이러한 코스에 따라 능력에 맞는 반복된 학습을 통하여 적극적인 완전학습을 수행하게 된다.

Load redistribution algorithm is a critical factor in computer system. In a receiver-initiated load redistribution algorithm, receiver(underloaded processor) continues to send unnecessary request messages for load transfer until a sender(overloaded processor) is found while the system load is light. Therefore, it yields many problems such as low cpu utilization and system throughput because of inefficient inter-processor communications until the receiver receives an accept message from the sender in this environment. This paper presents an approach based on genetic algorithm(GA) for dynamic load redistribution including self-adjustable in heterogeneous distributed systems. In this scheme the processors to which the requests are sent off are determined by the proposed GA to decrease unnecessary request messages.

There are several studies in order to learn about programming language. This paper develops a peer agent system based on teaching and learning strategies in order to improve problem-solving ability. Problem-solving ability involves three components - content understanding, domain-dependent problem-solving strategies, and self-regulation. This paper shows the teaching and learning strategies about components of problem-solving for learning to program and the peer agent system uses the teaching and learning strategies. This study intents to analyze the educational effects of the peer agent system. The results show that the system has superior effects on problem-solving ability compared to traditional programming courses or pair programming courses. It means that the peer agent system is the effective educational system in improving student's problem-solving ability.

Educational evaluation is not the work to rank learners hierarchically, but the thing to increase the educational effectiveness by solving a learner's problem and improving the education process from the proper evaluation. The conventional evaluation systems have measured a learner's recognition level by dichotomy. Although they support the evaluation depending on a learner's academic ability and supply the feedback for wrong selection, it is insufficient to take out study-motive and give the establishment for a guidance point of learning. In this paper, we propose the web-based individual adaptive testing system in considering partial score for a learner. Our system are effective to estimate the ability of learner by considering partial score in detail and offer an feedback study from the self-diagnosis function for a learning results.
