e-Learning, from concept to practice

Re-use of materialStandards

Why Creating Material Web environment for part time students

Wide scale implementation Resources are growing fast Teachers started creating resources University level

1600 courses 50 - 300 objects in every course With a average of 100 objects a course, this

is 160.000 objects More then 10.000 users

Reuse of Material Partly reuse of old courses Teachers created resources themselves Update resources where necessary Removed out of date resources Why differ from “old” HTML based

courses? Ease of use Generated links Teacher “controls” the content

Content Combination of material

Data Metadata & (not always) Attachments

Video Applets Flash animations MS docs

Powerpoint Word Excel Plaatjes

Units of Learning Material (ULM) Objects, documents, records in the

database, digital content, Also Assignable units (AU) or Shareble Content Object (SCO)

“ a ULM is an abstraction which collects a variety of segments of learning material based on different media and featuring different layouts, languages and encoding types, with their differences concealed to offer a common and consistent interface to it’s clients. A Ulm may be a simple monomedia object or a composition in space time (layout) of several pieces of learning material; its multimedia message to the user possibily includes texts, still frames, dynamic sequences and digital audio “
