Widgets can support the coconstruction of knowledge and
exchange of information = learning.
A ‘widget’ is a use-case sized
mini (web) application
A widget-based environment is a
flexible and harmonic arrangement
of interoperable mini apps, that
supports in a particular practice.
It’s personal, but we can
share it – across learners
and across universities.

EDUKApp ongoing development
Contribute at http://code.google.com/p/edukapp/
> Tracking service - monitor
Simple integration of Google analytics in each instantiation
and invocation of Goolge analytics API to retrieve stats
> Enhanced recommendation engine
Already there: recommendations based on content:
simple text matching, tags
Planned: recommendations based on social activity:
people who have used widget wA also interested in wB,wC
you have tagged widget W1 with TagA, you may be interested in widgets W2,W3
> Widget bundles
create collections of widgets, to share and instantiate all at once
Further potentials
• Export widgets as mobile applications
(through PhoneGap build service, rho-mobile,
corona sdk,..)
• Bind store with widget authoring tools
(widg@t)
• Sophisticated social requirement engineering:
users request for widgets, developers are
motivated to implement by badges/rewards/..
