An Educational Java Applet for Understanding Principles of Synchronous BCD Counters

摘要

This paper presents web-based Java applet for understanding the concepts and principles of synchronous BCD counter. Through our educational Java applet, the learners will be capable of learning the concepts and theories related to digital experiments and how to operate the virtual experimental equipments. The proposed educational Java applet is composed of three important components: Principle Classroom to explain the concepts and theories of synchronous BCD counters operations, Virtual Experiment Classroom to provide interactive Java applets 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. We have obtained several affirmative effects such as high learning standard, reducing the total experimental hours and the damage rate for experimental equipments.
