Abstract

To enhance the excellence, effectiveness and economical efficiency in the learning process, we implement a hybrid educational system for engineering experiments where web-based virtual laboratory systems and distance education systems are properly integrated. In the first stage, we designed client/server distributed environment and developed web-based virtual laboratory systems for digital systems and electrical/electronic circuit experiments. The proposed virtual laboratory systems are composed of four important sessions and their management system: concept learning session, virtual experiment session, assessment session. With the aid of the management system every session is organically tied up together to achieve maximum learning efficiency. In the second stage, we have implemented efficient and cost-effective distant laboratory systems for practicing electric/electronic circuits, which can be used to eliminate the lack of reality occurred during virtual laboratory session. The use of simple and user-friendly design allows a large number of people to access our distant laboratory systems easily. Thus, self-guided advanced training is available even if a lot of expensive equipment will not be provided in the on-campus laboratories. The proposed virtual/distant laboratory systems can be used in stand-alone fashion, but to enhance learning efficiency we integrated them and developed a hybrid educational system for engineering experiments. Our hybrid education system provides the learners with interactive learning environment and a new approach for the delivery of engineering experiments.

본 연구에서는 학습과정에 우수성, 유효성, 그리고 경제적인 효율성을 향상시키기 위해 웹기반 가상실험실과 웹기반 원격실험실을 적절하게 통합한 하이브리드 공학실험시스템을 개발하였다. 먼저 클라이언트/서버 분산환경을 설계하여 디지털 시스템과 전기전자회로 실험에 대한 웹기반 가상실험시스템을 개발하였다. 제안된 가상실험시스템은 개념학습세션, 가상실험세션, 평가세션등의 3개의 주요한 세션과 이들 주요세션을 유기적으로 통합하여 학습효율의 극대화를 달성하기 위한 관리시스템으로 구성되어 있다. 다음으로 본 연구에서는 가상실험세션 동안에 발생할 수 있는 현실감의 부족을 해결하기 위해 전기/전자회로를 실험할 수 있는 웹기반 원격 실험실을 구현하였다. 더욱이 간결하고 사용자가 친근하게 접근할 수 있는 설계기법을 사용하였기 때문에 많은 사용자들이 쉽게 원격실험실에 접속할 수 있으며, 고가의 실험장비가 실제 실험실에 구비되어 있지 않더라도 자기주도의 심화학습이 가능하다. 제안된 가상/원격실험시스템은 독립적으로 사용될 수도 있으나 학습효율을 향상시키기 위해서 웹상에서 두 개의 시스템을 통합하여 하이브리드 공학실험시스템을 개발하였다. 제안된 하이브리드 공학실험시스템은 학습자들에게 상호작용적인 학습환경을 제공하여 공학실험교육을 효율적으로 관리하는 새로운 접근방식이다.
