Sweden?
Welcome to Sweden
Linnæus University
• Sweden’s newest University, merger of Växjö and Kalmar Universities on January 1, 2010
• 31,000 students
• 15,000 full-time equivalents
• 2,000 members of staff
• a budget of € 155 million, with € 36 million earmarked for research and postgraduate studies
CeLeKT• School of Computer Science, Physics and
Mathematics
• 15 full staff
• Professor Marcelo Milrad + 2 Associate Professors + 1 post doc
• 5 Ph.D. Students + 1 visiting
• 3 Masters Students (for 2011)
• 4 Research Assistants
Research Focus
The design and development of mobile systems and social
media to support collaborative learning and intellectual work.
Current Projects
• Lets Go!
• GeM part of AMULETS
• Gifted Math
• mLearn2go
LETS GO!
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
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
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
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
Future Efforts
• Extending our system:
• full utilization of the visualization component
• web-based visual authoring tool
• Learning Management System
Linked Data Approach
Challenge• We are currently exploring to what extent
Linked Data can help to improve the semantic interoperability of ELO metadata.
The idea
• A graph illustration of an exemplary RDF statement:
The above statement facilitates data linkage via HTTP:
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
Illustrative Scenario
Insights
• Linked Data contributes with
• Expressivity
• Flexibility
• Data distribution

GeM & AMULETS
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
Quick View
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
GeM in Action
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
Software Ecosystems
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.
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.
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
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.

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