• GeM part of AMULETS
• Gifted Math
• mLearn2go

9. LETS GO!

10. Learning Ecology through Science with
Global Outcomes (LETS GO)
• The aim of the project is to design challenging
collaborative IBSL activities supported by mobile and
sensor technologies.
• Central notion that led the design and technical
development in the LETS GO project have been
“mobile science collaboratories”.
• In the scope of our project, “Mobile science
collaboratories” has been defined as a set of mobile
devices, open software tools, and resources, with online
participation frameworks for supporting learners’
collaboration and inquiry

11. Initial Efforts (spring 2009)
• Science sensors and mobile devices
for data capture and mapping
• Geo-visualization for data-analysis
• Pen-based paper computing
• Learning activity – Soil Quality

13. Learning Activity (winter 2010)
• Twelve students (16-17 years of age) – two hours per session - 5 weeks
• The field of investigation was related to water quality

14. Current efforts
• Exploring the benefits of open standard ini4a4ves
• XForms standçard for next‐genera4on data collec4on and
interchange (JavaRosa pla?orm )
• OpenDataKit (ODK) ‐ Open‐source and standards‐based tools
– ODK Collect ‐ built on the Android pla?orm
– Renders Xforms
– ODK Aggregate – server side data aggrega4on
• Various types of inputs:
– Text
– GPS
– Video/Audio/Image
– Barcodes.
– digital pens

15. Future Efforts
• Extending our system:
• full utilization of the visualization
component
• web-based visual authoring tool
• Learning Management System

16. Linked Data Approach

17. Challenge
• We are currently exploring to what extent
Linked Data can help to improve the
semantic interoperability of ELO metadata.

18. The idea
• A graph illustration of an exemplary RDF
statement:
The above statement facilitates data linkage
via HTTP:

19. Pinetree
• Pinetree is a content repository
implemented as a Linked Data
application
• Digital content are organised
according to the Pinetree core
ontology
• Core technologies used in the
implementation are Sesame and
Restlet

20. Illustrative Scenario

21. Insights
• Linked Data contributes with
• Expressivity
• Flexibility
• Data distribution

22. GeM & AMULETS

23. GeM
• Part of ongoing project cycle of 5 projects
of the last 4 years
• Forrest Studies for Primary School
• City Square History for Primary School
• Biology for Teacher Students
• GeM Geometry Mobile for Middle
School

24. Quick View

25. GeM Research Aims
• To explore how 1:1 and 1:M technologies
can support novel learning for mathematics
including mobile, 3D tools, and Mixed
Reality Visualizations
• Explore how the concept of software
ecosystems can be applied to mobile
learning
• Flexible and Multiple roles for mobile
devices

26. GeM in Action

27. Design Process
• Design-based Research with a strong co-
design process
• Challenges in balancing the team of
researchers and students
• Goal of producing educational innovations
while providing empirical research

28. Software Ecosystems

29. Tested in GeM
• The implementation of
the concepts and their
relation was succesfull
and utilized in the trial on
the server side.
• The notion of SECO was
largely unadressed in this
implementation however.
This is where my future
work will lie.

30. Flexibility in Mobile Devices
• Bring the concept of multiple roles in mobile devices.
• Client role
• Service Provider role
• Context Externder role
• Etc.
• Be able to provide the suitable role in the mobile device for each
situation, according to the environment information provided by
the context.
• Extend the potential related to flexibility in the LAS, wherein the
mobile device is involved.
• Allow direct collaboration between mobiles by the use of service
provider roles.

31. Flexibility in Mobile Devices
• Extends the roles a mobile device can have: client, service
provider, context extender, resource extender, etc.
• GeM provides a context-extender role (the GPS position).
• Technology: Flexible Activity Client
• Server-based roles are provided by a Web Server (MWS
[8]) running on the mobile device, and accessible
through the Internet
• The server composed of Apache, PHP, Python and
MySQL.
• Services are provided as Web Services using RESTful
methods
• The mobile device can offer device located services and
content, even its own sensored context.
• In GeM, a mobile device could request external GPS locations to
acquire multiple points (form multiple devices) and calculate
distances

32. Future Work
• Needed to expand the roles a mobile device can perform.
• Study for the reasoning to select the role in action. Dynamism in the
activation and deactivation of roles may be required.
• Web Server & Services activation based on the context.
• Study for the collaboration of several multiple-role mobile devices for
the creation of complex services in the aggregation of mobile devices.
• Introduction of Virtual Mobile Devices. Composition of mobile devices
working as a unity.

33. mLearn2go

39. Gifted Math

40. Utilizing Classroom Technologies
• Design a tool that leverages "seemless
interaction" as a means to enrich the
classroom experience towards fostering
development of "21st century skills" in
students.
• Collaboration with Catholic University of
Chile- Prof. Nussbaum and Alvarez

41. 1:1 to 1:M

43. In summary
• Our research is focused on both theory
and practice, driven by real-world
challenges in all types of education
• Our goal is develop a strong learning
science in Sweden not separate domains
• Plus, creating products for real-world use

44. Next Steps
• Investigate how we can collaborate
• NordiTel in Sweden August 26-27
• Joint funding application
• Student / researcher exchange
