Transcript

  • 1. CUELC Knowledge Multimedia Processes in Technology Enhanced Learning Ralf Klamma1, Marc Spaniol2, Matthias Jarke1 1RWTH Aachen University, Germany & 2Max Planck Institute for Computer Science ACM Multimedia WS Multimedia Technologies for Distant Learning MTDL 2009, Lehrstuhl Informatik 5 (Informationssysteme) Beijing, China, October 23, 2009 Prof. Dr. M. Jarke I5-RK-0909-1
  • 2. Agenda  Theoretical background CUELC – Cross-media theory of transcription – SECI model by Nonaka  Knowledge Multimedia Processes – Transcriptions – Practiced/Formalized Localizations – Addressing  Evaluations  Conclusions & Outlook Lehrstuhl Informatik 5 (Informationssysteme) Prof. Dr. M.

  • 3. Cross-Media Theory of Transcription Addressee-based Transcription Transcript Transcript CUELC Pre-Texts Selection of Pre-Texts Integration into the cultural Archive  Strategies of transcriptivity  Collection of learning materials are re-structured by new media  Design is specific for media and learning communities by default  Strategies of addressing  Social Software promotes the globalization of address spaces  Personalization is mission critical for learning communities  Strategies of localisation  Re-organization of local practices is stimulated by new media Lehrstuhl Informatik 5 (Informationssysteme)  Need to model learning practice explicitly Prof. Dr. M.
