Abstract

This paper presents a web-based Java applet for understanding the concepts in digital logic circuits and student satisfaction survey was carried out in order to show its educational validity. Through our educational Java applet, the learners will be capable of learning the concepts and principles related to digital logic circuit experiments and how to operate virtual experimental equipments and virtual bread board. The proposed educational Java applet is composed of five important components: Principle Classroom to explain the concepts and principles for digital logic circuit operations, Simulation Classroom to provide a web-based simulator to the learners, Virtual Experiment Classroom to provide interactive Java applet about the syllabus of off-line laboratory class, Assessment Classroom, and Management System. With the aid of the Management System every classroom is organically tied together collaborating to achieve maximum learning efficiency. Finally, we have obtained several affirmative effects such as high learning standard, reducing the total experimental hours and the damage rate for experimental equipments.

본 논문에서는 디지털 논리회로의 개념학습을 위한 교육용 자바 애플릿을 설계방법을 제안하고 그에 대한 교육적인 유효성을 입증하기 위하여 학생 만족도 조사를 실시하였다. 제안된 교육용 자바 애플릿을 통하여 학습자들은 디지털 논리회로 실험과 관련된 개념과 원리, 가상실험장비, 그리고 가상 브레드 보드의 동작방법을 학습할 수 있다. 제안된 교육용 자바애플릿은 5개의 주요한 요소 즉, 디지털 논리회로의 동작에 대한 개념과 원리를 설명하는 원리학습실, 학습자들에게 웹기반 시뮬레이터를 제공하는 시뮬레이션 학습실, 오프라인 실험교육의 강의계획서에 대한 상호작용성이 있는 자바 애플릿을 제공하는 가상실험 학습실, 평가와 관리시스템으로 구성되어 있다. 모든 학습실은 학습효율의 극대화를 위하여 서로 유기적으로 결합되어 있다. 마지막으로 높은 학습에 대한 기준, 전체 실험시간의 단축, 실험장비의 손상율의 감소와 같은 긍정적인 결과를 얻었다.
