자바 가상교육센터(Java Virtual Education Center)는 자바 프로그래밍 교육을 위한 가상교육시스템으로 인터넷과 웹 브라우저를 통해 사용자들에게 투명하게 자바 프로그래밍 실습 환경을 제공한다. 이것은 자바 컴파일러 실행을 웹 기반으로 구현함으로써 가능하게 된다. 본 논문에서는 자바 가상교육센터 구현에 적용된 자바 기술을 정리하고, 실제 자바 가상교육센터의 구조 및 동작원리를 설명한다. 또한 구현모델이 어떠한 설계개념을 가지고 구현되었는지를 살펴봄으로써, 향후 자바뿐 아니라 C나 C++와 같은 다른 프로그래밍 언어에도 적용할 수 있는 종합적인 프로그래밍언어 가상실습실의 구현 가능성을 제시한다.

본 연구에서는 Atmel사의 AVR 마이크로프로세서에 적합하게 개발된 Java 바이트코드 인터프리터인 NanoVM을 자체 개발한 마이크로로봇에 이식하여 Java 언어 전용 로봇을 구현하였다. 따라서 마이크로프로세서의 구조와 회로를 모르는 학생들도 로봇을 프로그래밍하면서 Java 언어를 효율적으로 학습할 수 있다. 더욱이 최근 학생들의 프로그래밍언어 학습 능력이 떨어지면서 컴퓨터 관련학과의 프로그래밍언어 교육이 많은 어려움을 겪고 있다. 따라서 학생들의 프로그래밍언어 학습 동기를 부여하고 창의 공학적 프로그래밍언어 교육프로그램의 도입이 필요한 시점에서 본 연구에서 개발한 Java 로봇은 많은 기여를 할 것으로 기대된다.

C programming is a main programming for the Educational Robot Arm which is based on AVR ATmega128. The development environment is not integrated, so it is complex and difficult to study for middle or high school students who want to learn programming and control the educational robot arm. Furthermore, there is no debug and testing environment support. This paper presents a Java-based development platform for the educational robot arm. This platform includes: an up-to-date tiny Java Virtual Machine (NanoVM) for the educational robot arm; An Eclipse based Java integrated development environment as an Eclipse plug-in; a 3D simulator on the PCs to support testing and debugging programs without real robots. The Java programming environment makes development for educational robot arm easier for students.

This paper presents a web-based virtual educational system for Java language, which consists of a management system named Java Web Player (JWP) and creative multimedia contents for the lectures of Java language. The JWP is a Java application program free from security problems by the Java Web Start technologies that supports an integrated learning environment including three important learning procedures: Java concept learning process, programming practice process and assessment process. On-line voice presentation and its related texts together with moving images are synchronized for efficiently conveying creative contents to learners. Furthermore, a simple and useful compiler is included in the JWP for providing user-friendly language practice environment enabling such as coding, editing, executing, and debugging Java source files on the Web. Finally, simple multiple choices are given suddenly to the learners while they are studying through the JWP and the test results are displayed on the message box. In order to show the validity of the proposed virtual educational system we analysed and assessed the learners' academic performance on the five quizzes for one semester.

This paper presents an internet-based self-learning educational system which can be enhancing efficiency in the learning process of Java language. The proposed self-learning educational system is called Java Web Player(JWP), which is a Java application program and is executable through Java Web Start technologies. Also, three important sequential learning processes : concept learning process, programming practice process and assessment process are integrated in the proposed JWP using Java Web Start technologies. This JWP enables the learners to achieve efficient and interesting self-learning since the learning process is designed to enhance the multimedia capabilities on the basis of various educational technologies. Furthermore, internet-based on-line voice presentation and its related texts together with moving images are synchronized for efficient language learning process. Also, a simple and useful Java compiler is included in the JWP for providing language practice environment such as coding, editing, executing and debugging Java source files. Finally, repeated practice can make the learners to understand easily the key concepts of Java language. Simple multiple choices are given suddenly to the learners while they are studying through the JWP and the test results are displayed on the message box. This assessment process is very essential to increase the learner's academic capability.

Object Oriented Programming Languages including Java require Object-oriented thinking first for programming. However, for Korean students it is not easy since they are fully accustomed to Korean language which does not have the Object-oriented concept. This paper proposes a way of teaching the Object Oriented Languages to Korean students. It explains first how to organize our thoughts in Object-oriented way, and then how to express the thoughts with the languages.

Java provides support for Web, concurrent programming, safety, portability, and GUI, so there is a steady increase in the number of Java users. Java is based on the object-oriented concepts such as classes, instances, encapsulation, inheritance, and polymorphism. However the JVM(Java Virtual Machine) hides most of the phenomena related to the concepts. This is why most of Java users have much difficulty in learning and using Java. As a solution to the problem, I have developed a tool Alpha that visualizes the phenomena occurred in the JVM from the standpoint of the concepts and will describe the design and features of the tool in this paper. For practicality and extendability Alpha has an MVC(Model-View-Controller) architecture and visualizes the phenomena such as object instantiations, method invocations, field accesses, cross-references among objects, and execution flows of threads in the various ways according to the levels and purposes of the users.

In the knowledge based society, the development of creative human resources is one of the core factors for securing a national competition power. Especially in the software industries, the development of human resources who can solve a problem creatively by applying object oriented programming technique which is a update Programming technology is required. In this paper, we designed a lecture plan and produced it into a course contents which could be run on a online learning system. The teaching focuses of the developed course are the development of problem solving ability and object oriented design and programming ability through Java.
