Foundations - 5S Framework -
S’s Role in DL Examples
Streams Various types of content text, video, audio
Structures Organize information catalog, metadata,
hypertext
Spaces Store and present information interfaces, storage,
vector space
Scenarios Provide services searching, browsing,
recommending
Societies Form a DL community of users
and service managers
service managers,
teachers, learners
Theoretical foundation
Necessary condition to be a Minimal DL

Example: Guiding + Specific Questions
Body of knowledge:
Guiding question: Does the module address all
areas of the topic that need to be addressed?
Specific questions:
Will the body of knowledge enable students to
achieve the objectives?
Are there any topics that you think are critical to
add to the body of knowledge?
Are there any topics that you would remove from
the body of knowledge?

Future work – Resource presentation in a module –
Superimposed Information (SI) Technology
Sub-document level granularity presentation
“Marks”: references to selected regions within
base (original) information

Future work – Plans for module distribution –
Using wikisWikiversity: distribute modules, set up a DL community
Wikibooks: DL booklet
Using Second Life (secondlife.com) 3D virtual environment
Supports collaborative, distance learning
