The “WWW invasion” in education
Growing amount of informationLack of adequate support Missing link between the students and instructorsFinding and validating relevant educational information

Looking for a solution
methods to support both students and instructorsinformation handling tasks:
searching for relevant information on a certain topicsapplying information for course tasksvisualization, organizing, structuring and maintainingvalidating information

Aims of the research
investigate the problems related to user-oriented and context-based information handling within Web-based education propose an approach for efficiently managing course-related information resourcesincreasing personal satisfaction and performance of students and instructors in their course-related tasks

From the aims to AIMS
AIMS – Agent-based Information Management System AIMS method – indirectly guiding and assisting both students and instructors in performing their course related activitiesAIMS tool – facilitating students and instructors with techniques to apply AIMS method and this way to achieve higher course performance

Proposed approach (2)
A three dimensional scheme is constructed in order to link all the aspects of the proposed solution for information handling support within the context of web-based education - ATP Model (Approach-Technology-Process):
Visualisation techniques Semantic information modelling Intelligent support for cognitive processes

AIMS Global Information Model
Domain model - defines the subject-domain ontology by means of a concept map (CM) of domain concepts with links between them
– domain concepts - linked to documents with weight indicating the relevance – domain concept - component of the user model as an overlay on the domain CM
Library model - provides means for maintaining a collection of information items related to different courses and domains - course materials and domain-related documents together with their characteristics
– library documents - domain terms, course tasks and topics – document - component of the user model as an overlay on the library documents
Course model - defines the structure of a course: course topics and tasks– task is represented in terms of domain concepts: includes task description,
prerequisites, and task status
Learner model - represented in terms of course tasks, domain concepts, and library documents: an overlay on the subject domain CM and course and library models; open model, built jointly by the user and the system
