Developing Web-based Tutoring Agents Using CORBA
Save to My Collections
An agent-based approach is used for the design and implementation of a Web-based learning environment in general chemistry laboratory domain. By taking advantage of the common object request broker architecture (CORBA), four kinds of agents are implemented: i) the student agent that models students' learning progress, ii) the expert agent that simulates domain expertise, iii) the intelligent tutoring agent that scaffolds students' problem-solving processes and the iv) adaptive lecture guidance (ALG) agent that presents students with adaptive navigation plan. The advantages of this approach are two-fold. First, the CORBA middleware provides the distributed communication infrastructure for agents to cooperate and to produce intelligent tutoring behaviors (ITB). ITB is a critical component to achieve learning efficiency in WWW environments. Second, the modular and platform independent characters of these agents bring the potential for cooperative development of reusable educational contents, which in turn provides a more cost-effective system.
