2. ROLE
The ROLE project aims at building a framework that allows a
learner to easily construct (mash up) and maintain her own
Personal Learning Environment.
Components of this framework are
• a SDK for learning environments
• a space feature in OpenSocial
• recommender systems
• libraries (usage tracking, IWC, …)
• a widget store

3. Goal of the ROLE Widget Store
Create a cross-platform marketplace focusing educational
applications and assisting the learner in selecting applications
for their needs and learning goals

4. Why Another Application Store?
While there are several (well known)
application stores, stores focusing education
are still rare

6. Why Using Widgets for PLEs?
• Widgets allow flexible mashups in web platforms
• On the one hand they provide very simple functionalities at
their own
• On the other hand they can be communicate which each
other and combined to create a larger piece of software
Supported by a large
number of learning
environments

9. Widget Bundles
A widget bundle is a set of widgets that complement each
other and are used together for a common purpose to fulfill
a specific learning goal

• Bundles can be shared with the community
• The community can rate, comment and discuss
these templates and add them to a learning
environment

12. Categorization
In order to support the learner in selecting widgets /
bundles the store provide several categorization
system for different purposes
• Identify the learning phase
• Identify the functionality
• Identify the learning domain

13. Tool categories
For which learning phase can a tool be used?
• Categorization based on the PPIM model
© www.role-project.eu

14. Tool Functionalities & Learning Domains
What for functionality does a tool provide?
• Categorization based on a functionality ontology

15. Learning Domains
In which learning domain can the tool/bundle be
used?
• Categorization based on dppedia.org

16. Connectivity
Different approaches to add widgets to PLEs
• Add manually (copy reference, download)
• Push (e.g. iGoogle)
• Via JavaScript
• Web services (SPARQL, REST)
• Embedded HTML Code

18. Future Work
• Include more tool types (Desktop, Mobile)
• Connect with other systems
• Add Recommender
• Evaluate the system
• Add social requirement
engineering tool
• Release new version

19. Widget Contest
 Bring together the best ideas from software
developers and practitioners
 In the first round contribute your specification of a
learning widget (no coding)
 Three selected specifications have two months to
develop their learning widgets
(supported by a ROLE partner)
 Deadline first round: 29 July 2012
