Utilizing Learning Objects Repositories for Enhanced E-Learning Environments

This document discusses the development and implementation of the eduSource suite of tools, showcased during the Industrial Forum in Moncton on June 12, 2003. Dr. Gilbert Paquette from the CIRTA and Cogigraph Technologies emphasizes the importance of Learning Objects (LO) as reusable digital or non-digital entities that enhance technology-supported learning. The document explores instructional engineering, knowledge management, interoperability standards, and the evolving landscape of e-learning through the integration of these resources, focusing on their application, development, and metadata specification.

  2. Road Map • Organizations • 1972 TELUQ–Québec’s Distance University • 1984 Canal Savoir – Broadcasting Consortium • 1992 LICEF – TELUQ’s Research Centre • 1999 Cogigraph – Transfer Company of LICEF • 2000 CIRTA – LICEF Based Research Network • R&D Projects • 1992-1995 AGD and Telecom multimédia • 1995-1998 HyperGuide. TL-NCE, Advisor Systems • 1999-2001 Explor@-1 and ADISA • 2001-2003 SavoirNet and Explor@-2 • 2002-2004 eduSource Canada • 2003-2008 LORNET – NSERC Research Network • Main Focus on Instructional Engineering • Tech Transfert to Universities and Organizations

  5. Exciting Megatrends • Third Wave, Semantic, Progammable Web • Knowledge Management • Object-based Learning Environments • Interoperability Standards New Potential To Renew Pedagogy ? What are the conditions ?

  6. Internet’s Third Wave • First wave: STATIC TEXT and DATA EXCHANGE • Primarily static HTML pages: text and data services • E-mail, FTP, forum (asychronous communication) • Second wave: DYNAMIC MULTIMEDIA • Dynamic pages, ASP, JSP • Facilitated transfer of images, sound and video • Desktop audio/video conference • Third wave: SEMANTIC and PROGRAMMABLE • Integration of applications, API enabled by web services • Ex: Google Alerts, Amazon’s API • Distributed computing, P2P, and mobile networking • Semantic web and knowledege-based technologies • Open source, sharing of objects and applications • New generation of Distributed Learning Environments

  10. eduSource Infrastructure

  11. Learning Objects: An Open Concept “A learning object is any entity, digital or non-digital, that can be used, re-used, or referenced during technology-supported learning”. (IEEE LTSC 2000) • Includes materials, tools, services, persons, events • Not necessarily digitized, include printed, lab material • Used not only by learners, but also other actors • Includes target and prerequisite competencies or objectives, activity descriptions, instructional structure, learning or assistance scenarios, etc. Information Resources is better

  12. Building LO Repositories

  13. Referencing Learning Objects: describing properties and types

  14. Searching for Objects

  15. Use cases • Learners (or workers) use LOs in activites and/or produce LOs that are shared and/or assessed • Trainers (or managers) point interesting LOs to learners, follow or adapt designs and activities, use LOs to assist learners (workers), manage repositories • Content Experts build LO repositories and use them to give advice, presentation or answer questions • Designers build, find, select, store, reference and assemble LOs (including designs) in environments (just like a campus professor)

  16. Cognitive Engineering Information Instructional Engineering Knowledge Knowledge Management and LOs • Knowledge Management is more than « glorified » document management • It aims at knowledge sharing and dissemination in an organization • Increasing competencies instead of simple information access • Higher level knowledge • Central role for knowledge-based Instructional Engineering.

  17. LOM: a step to the Semantic Web • Knowledge Management: a process where persons publish and use knowledge objects (resources) on the Web – learning is central • Knowledge Objects are grouped in « learning objects repository » • Knowledge Objects are described by their Metadata: properties and types of objects • Metadata are a basis for a Semantic Web description of object • Need to be completed by an Ontology: relations and axioms • To provide intelligent processing of content

  18. Value-added Service: Aggregation

  19. Learning Design Aggregation

  20. Apprenant Environment Aggregation

  21. Environment Construction

  22. Obstacles and Challenges • Generic Software • Separated tools • Integrated Suite • Interoperability at the OS level Technical Challenges • DL System • Separated Tools • LMS, LCMS • Web services interoperability

  23. Pedagogical Challenges • The object paradigm is economical, flexible and forces pedagogical re-evaluation • Attach more importance to communication and learning activities than medias, documents or content • Seperate content object from use scenarios and learning environments • Reusability must protect ne good quality learning scenarios • Reuse of learning models can bring more than just recycling content.

  24. Cultural Obstacles • Lecturing instead of facilitating learning • The library « course » • Lack of pedagogical training of the majority of teachers • Reproduce the way we have been taucht • IP vs Open Source • Collaboration between content creator and institutions
