효과적인 교육을 위한 다양한 연구들이 진행되어 왔지만, 이러한 결과를 실제 수업현장에 적용하기에는 많은 시간과 노력 등이 필요하여 잘 활용되지 못하고 있는 것이 현실이다. 따라서 교실 수업, 특히 지필 위주의 수업에서는 여전히 따분해하며 집중하지 못하는 학생들을 흔하게 볼 수 있다. 본 연구에서는 학생들의 적극적 참여를 통한 효과적인 교육을 구현하기 위한 방안으로 구성주의적 교수학습 방안과 정보 기술을 기반으로 교수자와 개별 학생들 사이의 실시간 상호작용을 극대화시키는 교수방안을 제안하고자 한다. 구현 사례로 통계적 추정의 표본추출 단원에 적용할 수 있는 교수학습 모형과 시스템을 제시한다.

This study examined contents of interaction that played an important role in learners' accomplishment of educational goals at web-based educational system. The purpose of the study was to find out design strategies of web-based education website that could give learners more satisfactory interaction. The study firstly investigated concept and values of web-based education as well as interaction by literature study to analyze web-based educational design principles at actual web-based education websites from point of view of interaction and to examine what factors should be used and reinforced at existing teaching. The findings were as follow: Web-based education websites made use of interaction with 'each design factor', such as colors, texts and images, etc that were based on communication designs to give 'information' by systematic interaction more than by social interaction.

In this paper, we can easily update teaming information by using database built in web server system in implementation of a web courseware that a learner can effectively team the 'Digital Circuits' subject. Also, we offered multimedia elements such as graphics, animations, and voices etc. for increasing understanding and interaction of teaming and designed and implemented a simulation-type web courseware of practice-oriented. In result, it can encourage a learner with a motive of learning and increase effects of teaming. Also, a learner can learn various contents because we can add teaming contents to database according to needs. Furthermore, it can improve understanding for teaming by offering feedback on the result. In future, we need to design and implement circuits with more complex and many functions by adding circuit with function that can store.

In this paper, we proposed the "synchronous & asynchronous distance education system" which is able to interact among teachers and students for open education in cyberspace, and it is based telecommunication technology and multimedia technology. Specially, This system gets rid of the nufamiliarity and inconvenient feeling during the distance education. Also it supports the mediation of floor mode, for a group lecture and supports the synchronous mode for face-to-face effective and asynchronous mode for self-learning. The asynchronous mode has the down load function and the consultant mode (between teacher and student). The element technologies of this system consists of application sharing technique, whiteboard, various video window display, audio support, user interface, environment setup, session management, access control, network control and media control for collaborative distance education.

대화시스템이 적절한 응답을 제시해 주기 위해서는 사용자의 의도를 분석하는 것은 중요한 일이다. 사용자의 의도는 도메인에 독립적인 화행과 도메인에 종속적인 서술자의 쌍으로 나타낼 수 있다. 사용자 의도를 정확하게 분석하기 위해서는 화행과 서술자를 동시에 분석하고 대화의 문맥을 고려해야 한다. 본 논문에서 제안하는 모델은 합성곱 신경망에서 공유 계층을 이용하여 화행과 서술자간 상호작용이 반영된 발화 임베딩 모델을 학습한다. 그리고 순환 신경망을 통해 대화의 문맥을 반영하여 발화를 분석한다. 실험 결과 제안 모델이 이전 모델들 보다 높은 성능 (F1-measure로 화행에 대해 0.973, 서술자 0.919)을 보였다.

A ultimate purpose of education is to develop their ability that learners is able to solve present or future immediate problem well. In order to, the educator checks question settlement conditions and leads steadily, the learner needs various data and information for question settlement, and needs communication with many various people. By the way, WEB becomes the source of various data and information that it is naccesary to solve problem for freedom navigation of internet, because accelerates interaction quality communication needed question settlement process, offers the best studying environment for problem solution drilling. A methodolagical tactics for accelerating learner's question solution activity is helped by small-group action drill. According to, this treatise develops system of question solution drilling with web for a basis by small group action drill, applies the fifth grade it experimentally.

The vicious cycle of over-education has been made. That is, higher education enrollment rate is high, but university graduate employment rate is low. To eliminate this cycle and relieve youth unemployment and young people to enter the labor market early, dual education and training system is needed. This dual system can support working and learning in parallel. So, worker can get the opportunity pre-employment and post-learning and improve his/her job skills. Recent MOOC (Massive Open On-line Course), a new form of online education system, has emerged. MOOC combines education, entertainment and social networking, and emphasize the interaction between faculty and student and between students. The educational contents of MOOC are available free of charge. Using newly changed online education environments we can effectively provide knowledge and skills. In technology and engineering education hands-on training is necessary. In order to support work based learning dual system for worker to work and learn in parallel, we should build the multi-learning system to combine the online education and campus hands-on practice.

This research suggests the framework for human body learning system using various forms of bidirectional interfaces. The existing systems mostly use the limited and unidirectional methods which are merely focused on the visual information. Our system provides more realistic visual information using 3D organ models from the real human body. Also we combine the haptic and augmented reality techniques into our system for wider range of interaction means. Through this research, we aim to overcome the limitation of existing science education systems and explore the effective scheme to fuse the real and virtual educational environment into one.
