National Cheng Kung University

  1. 1. Center for Learning and Knowledge Technologies 2010 Taiwan Tour Daniel Spikol Martin Svensson Bato Vogel Didac Gil Oskar Pettersson
  2. 2. Agenda • Welcome to Sweden, Linnæus University and CeLeKT • Research Mission • Our Team • Current Research Projects • Next Steps for Collaboration
  3. 3. Sweden?
  4. 4. Welcome to Sweden
  5. 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. 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. 7. Research Focus The design and development of mobile systems and social media to support collaborative learning and intellectual work.
  8. 8. Current Projects • Lets Go! • GeM part of AMULETS • Gifted Math • mLearn2go
  9. 9. LETS GO!
  10. 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. 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. 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. 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. 14. Future Efforts • Extending our system: • full utilization of the visualization component • web-based visual authoring tool • Learning Management System
  15. 15. Linked Data Approach
  16. 16. Challenge • We are currently exploring to what extent Linked Data can help to improve the semantic interoperability of ELO metadata.
  17. 17. The idea • A graph illustration of an exemplary RDF statement: The above statement facilitates data linkage via HTTP:
  18. 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. 19. Illustrative Scenario
  20. 20. Insights • Linked Data contributes with • Expressivity • Flexibility • Data distribution • More info available at http:// www.casualsemantics.se
  21. 21. GeM & AMULETS
  22. 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. 23. Quick View
  24. 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. 25. GeM in Action
  26. 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. 27. Software Ecosystems
  28. 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. 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. 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. 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. 32. mLearn2go
  33. 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. 34. 1500 gamers & designers • summer school programs Växjö • school activities with Mapping and CeLeKT • Kronobergskola & Norregård • teacher training programs • dreamhack 2009 m4action AB
  35. 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. 36. The Platform m4action AB
  37. 37. video the tool m4action AB
  38. 38. Gifted Math
  39. 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. 40. 1:1 to 1:M 1. Task Definition 1 2. Individual Response 3. Response Submission Done 4. Responses Review

  42. 42. 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
  43. 43. Next Steps • Investigate how we can collaborate • NordiTel in Sweden August 26-27 • Joint funding application • Student / researcher exchange
