최근의 인터넷환경은 다양한 형태의 가상 및 원격 교육이 가능한 기반을 제공하고 있으며, 대학 및 교육기관에서는 이를 활용한 새로운 교육용 도구의 개발이 활발히 이루어지고 있다. 본 논문은 시공간의 제약 없이 실험을 수행할 수 있도록 하여 학습자들에게 반복 학습이 가능하도록 하였고, 유량제어를 실현 할 수 있는 비선형 시스템의 이중탱크 기구를 이용하여 다양한 제어이론을 실험할 수 있는 웹기반 실험실을 구현하였다. 전체 시스템은 SISO 시스템과 MIMO 시스템을 학습자가 선택하여 실험할 수 있도록 하였다. 유량제어 방식은 수동, PID, FUZZY 제어로 실험할 수 있도록 하여 학습자들에게 여러 가지 제어이론을 다양하게 학습할 수 있도록 구성하였으며, 릴레이 자기 동조법을 구현하여 학습자들로 하여금 PID변수를 확인할수 있도록 하였다. 또한 Web-Cam을 통하여 실험화면을 실시간으로 확인하면서 시뮬레이션을 동시에 실행하여 비교할 수 있도록 구현하였다.

In this paper, a system configuration method that can practice Linux-based programming language online is presented. The proposed system utilizes the web-server function, which is the biggest feature of the Linux operating system, and simulates the telnet and FTP functions without firewalls or other security restrictions, so that it is possible to practice similar to the actual Linux console. To do this, we analyzed the functional elements that a programming tool should have on the web and established an algorithm to implement it. In particular, a method was implemented in which an error message caused by a user's mistake can appear in the same form as the actual telnet screen. As a result of using the implemented learning system in the class for students, it is possible to practice the Linux programming language online, as well as the instructor can directly check and guide all the learners, so the learner's satisfaction is similar to that of the offline class was confirmed.

In this paper, the simplification procedure of Karnaugh Map, which is essential to design digital logic circuits, was implemented as a web-based educational tool by Java applet. The learners can make virtual experiments on the simplification of the digital logic circuit by clicking on some buttons or filling out some text fields. The proposed simplification procedure was implemented as a Java applet which is based on the Modified Quine-McCluskey algorithm. Thus, the implemented Java applet will enable the learners to enhance the learning efficiency as a auxiliary educational tool.

Developing Computational Thinking is getting attention as the importance of SW is emphasized. Also programming education is getting attention, especially, various researches that utilize robot in programming education are being carried out. This study focused on compensating the defects of the prior robot programming education and exploring the way of utilizing web based tool 2.0 while putting emphasis on communication and cooperation. This plan is based on $Gagn{\acute{e}}$ & Briggs nine events of instruction and can be used to implement cooperative learning with the Web 2.0 based tools at every instructional events. Tests for learner's cooperation were done before and after this new plan to evaluate its value. The result proves that this plan had a positive influence on improving learner's cooperative attitude.

Quantum chemistry has many concepts that are either abstract or counterintuitive, giving students difficulties in understanding them. Fortunately, the advancement of web technologies provides us with hordes of powerful tools to produce rich multimedia web applications that supplement traditional classroom teaching. In this paper we present an approach to address this issue that combines interactive simulations and visualization on the web browser using Shockwave technology. With several examples, we show how to take advantage of the features of the Shockwave technology in developing web-based course material with ease.

Although the acquisition of information may be done individually, knowledge is created from the social context of peers, teachers. And feedback on the appropriateness and effectiveness of their knowledge and skill is commonly received. Learning occures effectively within environment that have shared understanding of problems and various tools to solve problems. The purpose of this study is to apply the main principles of creative Problem solving and develop e-PBL(Problem-Based Learning) to enhance creative problem solving skill. In this research, the group of students who studied by means of e-PBL based on web 2.0 showed much more satisfaction and problem solving skill than the other group of students who did by e-Learning.

Recently both the importance and the interests of field-experience learning have kept increasing since the Education of Ministry encourages students to take a field-experience learning with the self-driven and creative education as the main issue in the 7th revised education curriculum in 2009. As the importance of field-experience learning goes up continuously, not only the release of its related mobile applications is increasing, but also a variety of researches for supporting the field-experience learning are ongoing. In this research we perform two things. First, we define the basic concept of authoring tool for which support the field-experience learning based on its characteristics and user requirements analysis. We confirmed that the authoring tool for the field-experience learning has to 1) support all activities that happen in pre-field, field-experience and post-field phases, 2) be possible to write the location-based field work, 3) have the authoring function which reflects the characteristics of curriculum such as history, science and geography, etc. that the field learning can be realized, 4) be designed as the structure that the results of inquiring activity after the field experience activity can be reused. Second, we create a conceptual design after confirming the authoring tool.

In this paper, I discuss the development techniques and implemented type of DAVIS, a standalone JAVA-based application, by which statistics application can be downloaded from a web server, stored and installed to a client. Also I discuss both the server-based application and the client-based application that analyze statistics data. Considering the strengths and weaknesses of types discussed previously, I propose an advanced learning system of statistics that can execute an application in a client by client request. And data used in this system are loaded from a database server or input into a client by users.

Internet service, a part of our life, requires the changes not only of environment in our life but also of people's sense of value. It also requires a quick change in the spear of education activities without exception. It brought a lot of changes into educational methods, our recognition on education, and various kinds of educational tools and environment. The introduction of WBI (Web Based Instruction) is one of the most important thing. This study have applied WBI to Industrial high school education to improve its quality and accomplish its effective teaching-learning. That is, we have applied CNC(Computerized Numerical Control) and Processing learning to machining center learning and have given students chances and various learning materials so that they could contact with new information. We aimed at testing and studying some effects on the improvements of learning accomplishment and motive in this study.
