Top downapproach The topics of today Knowledge corpuses in different domains Today Content transmission model Social construction model The learner'sknowledge structure of a domain The future Down up approach
The top down approach of today • Digital libraries • Learning Resource Repositories • Portals exposing links to resources • LOM profiles • Content exchange • Easy access to content - removing barriers (IPR, identifiers….)
Don’t forget the interests involved Standardization of e-learning technology is a complex negotiation of meaning and interests within large actor-networks of strong individual intellectuals, companies, users and user organizations, software vendors, international bodies, system architectures, message definitions, individual data elements and specifications - comprising both human and nonhuman actors.
ICT technologists Content managers and publishers Academia The educational community? The learner’s interests? E-learning community Library community Knowledge management community Who are designing e-learning? ”Learning is construction of meaning” ”Content is king”
Are we designing/modelling the right stuff? • LOM, digital libraries are big world phenomena • Learning processes are small world phenomena We have to follow both tracks – or we do not succeed!
Are we succeeding? • Learning Resource Repositories are not used as much as we hoped for • Metadata are not provided, very often of bad quality, and above all: expensive • Portals (quality assured resources) are not used • Internet is used: General search engines, e.g. Google
I feel proud having so many keywords • I have to be more focused when reading to be able to extract keywords and look for connections • It easy to go back and look at what we have learnt

Tosca MadameButterfly Puccini Lucca Theme id and the “third layer” • There is a third layer: “the reality” • Every topic in the topic map represents a theme in “the real world” • The theme id tells what theme a topic represents • With a PSI (published subject indicator) topics may be shared across topic maps, e.g. http://psi.opera.org/composers/#puccini “The reality” Topic map
Theme id – so what? • With theme id I’m able to • Connect topics in my topic map to topics in yours • Download a bit of your topic map and merge with mine • Define standard topics that others might use • Theme id make topic maps global • They may be connected to other topic maps • The goal: Consolidated knowledge • We don’t have two topics for the same phenomenon • Instead we merge the duplicates
occurrence Merge the to topics Merge the to topics…...and the new topic has the sum of all the attributes of the two originals occurrence occurrence name name T T T name association role name association role name association role A second topic “about”the same subject association role Merging is like… • Thanks to theme id it is possible to merge topics maps automatically • When to topic maps are merged, topics that represent the same theme are merged to one topic • An when to topics are merged to one, the new one gets the sum of all attributes of the two original ones

Learning paths • Each student builds his or her own “brainbank” • The brainbanks are merged within a project • Projects expose their brainbanks, e.g. as XTM (without any editing) • These multiple brains banks could be merged into other web sites • A brainbank with your own material could be shared as a learning object
And some time the small world and the big world will meet… ..and I’ll be in Scotland before you The knowledge corpuses stored in Digital libraries My knowledge Our knowledge
