Resource Manager for Distance Education Systems

This document discusses the Resource Management (RM) system designed for distance education, enabling the sharing of various resources among users. The RM is not limited to laboratory equipment but includes software applications and data interfaces. It employs an object-oriented approach and standardizes communication protocols using XML. The implementation is primarily in a Windows environment with agents developed in Java. Through user testing with students from Macedonia and Italy, the RM's usability was validated, leading to enhancements based on feedback. The RM introduces an extensible framework to improve distance learning experiences.

  2. THE WHOLE PICTURE

  3. Introduction • The general idea of the Resource Management system is to enable sharing of many different resources between as many users as possible. • The idea of the resource is not limited to some laboratory equipment. It can be some software application or some interface to data stored in a remote database for example.

  4. Principles • object-oriented approach • the object communication is standardized • stationary agents as entities that work on different tasks in the system • all communication protocols within Resource Manager are defined using XML

  5. Logical Model:The architecture of the RM

  6. Resource Manager Model:Class diagram

  7. Resource Manager Model:Collaboration diagram

  8. XML defined protocol

  9. Implementation RM is implemented in Windows environment. All agents are developed in Java, with exception of Resource Simulation Agents, which are based on DCOM technology. The main components of the RM service

  10. Implementation:Resource Manager in action resource: XML Validator resource: Robot Car http://odl-skopje.etf.ukim.edu.mk/vlab/

  11. Experimental Results • We involved end users (students) in functionality testing and used feedback from them to add all requested functionality • We involved 38 users from Macedonia and Italy in the usability and education efficiency analysis. • In general, users are satisfied with the RM usability

  12. Conclusion • We extended the concept of distance education with adding a new service, that we call Resource Manager • By combining object-oriented design and definitions of common interfaces for the different types of agents for different types of resources, we designed extensible system, in which resources are added in an easy way.
