  • 3. Sweden?
  • 4. Welcome to Sweden
  • 5. 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
  • 6. 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
  • 7. Research Focus The design and development of mobile systems and social media to support collaborative learning and intellectual work.
  • 8. Current Projects • Lets Go! • 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
  • 12. 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
  • 13. 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
  • 14. Future Efforts • Extending our system: • full utilization of the visualization component • web-based visual authoring tool • Learning Management System
  • 15. Linked Data Approach
  • 16. Challenge • We are currently exploring to what extent Linked Data can help to improve the semantic interoperability of ELO metadata.
  • 17. The idea • A graph illustration of an exemplary RDF statement: The above statement facilitates data linkage via HTTP:
  • 18. 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
  • 19. Illustrative Scenario
  • 20. Insights • Linked Data contributes with • Expressivity • Flexibility • Data distribution • More info available at http://
  • 21. GeM & AMULETS
  • 22. 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
  • 23. Quick View
  • 24. 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
  • 25. GeM in Action
  • 26. 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
  • 27. Software Ecosystems
  • 28. 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.
  • 29. 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.
  • 30. 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
  • 31. 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.
  • 32. mLearn2go
  • 33. mLearn2go • the beginning - joint venture university, ngo, & mapping växjö project • Started in 2007 after school “fritids” • 2009 ORingen youth competition • pilot tests with AV Media Kronoberg • 2010 m4action AB m4action AB
  • 34. 1500 gamers & designers • summer school programs Växjö • school activities with Mapping and CeLeKT • Kronobergskola & Norregård • teacher training programs • dreamhack 2009 m4action AB
  • 35. mLearn2go Product • A learning toolbox that includes software and hardware that enables learners to explore the world. • Applying real-world contexts to abstract knowledge m4action AB
  • 36. The Platform m4action AB
  • 37. video the tool m4action AB
  • 38. Gifted Math
  • 39. 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
  • 40. 1:1 to 1:M 1. Task Definition 1 2. Individual Response 3. Response Submission Done 4. Responses Review
