2 People learn in Communities
"Learning is conceptualized as a social system within communities of practice" [E. Wenger, Communities of practice: Learning, meaning and identity] Best way to learn: in groups Social software applications Mobile and ubiquitous technologies  social systems for mobile knowledge sharing Mobile Web Services for Collaborative Learning

3 Mobile Web Services for Collaborative Learning
Overview Shift from e- to we-learning and the potential use of social software in collaborative learning Mobile and ubiquitous learning Mobile web services architecture The Mobile Host: implementation and evaluation Conclusion Mobile Web Services for Collaborative Learning

4 From e-learning to we-learning
e-learning content today is managed via centralized systems e-learning is more than authoring / delivering static content It should occur within a socially open context which supports listening, viewing, reading writing, co-creating discussing, commenting ... and sharing of dynamic learning resources and best practices  move away from e-learning to we-learning e-learning should place more focus on collaboration Mobile Web Services for Collaborative Learning

5 Mobile Web Services for Collaborative Learning
Social Software Web shifts from consummation to read-write Web (Web 2.0) sharing collaboration collective intelligence distributed content Social Software supports social feedback social networks Examples Wikis Blogs Media sharing and social tagging  Social network of people with similar interests Mobile Web Services for Collaborative Learning

6 Mobile Social Software
mobile publishing, listening, and sharing of resources. new variants of blogs: phlogs: photographs as primary content moblogs: mobile blogs, post content from a mobile device podcasting: iPod and broadcasting, audio files recorded by individuals and then distributed via webfeeds vodcasting: video-on-demand Mobile Web Services for Collaborative Learning

7 Social Software for Learning
Should support collaborative learning and foster socialization and network building Wikis collaborative learning content creation, organization, and peer editing Blogs online knowledge publishing systems categorize learning resources collaboratively with tags find learners with same interests or subscribe to tags webfeeds disseminate up-to-date learning content Podcasting and Vodcasting for replace or complement classroom or online lectures feedback to learners enable to re-view training or lectures Mobile Web Services for Collaborative Learning [E. Kaplan. Trend: Podcasting in Academic and Corporate Learning. Learning Circuits.]

8 From e-learning to m-learning and u-learning
Learning is mobile  m-learning Learning supported by embedded computing  u-learning Mobile devices in learning: take pictures and video clips send s, texts and graphics browse the web download programs access lectures Mobile Web Services for Collaborative Learning [S. Sharma, and F. Kitchens. Web Services Architecture for M-Learning, Journal on e-Learning] [G.N. Vavoula, and M. Sharples. KLeOS: A personal, mobile, Knowledge and Learning Organisation System. WMTE2002] [M. Prensky. What Can You Learn from a Cell Phone? Almost Anything! Innovate, Online Journal ]

9 Mobile Web Services Architecture for Collaborative Learning
Software as a Service (SaaS) Service-Oriented Architecture (SOA) loose coupling and clean encapsulation Web Services Web Services Description Language (WSDL) standards, such as SOAP and HTTP UDDI registry (yellow pages) All Web Services standards are based on XML  Web Services are a perfect fit for settings involving many peers Mobile Web Services for Collaborative Learning

10 Mobile Web Services for Collaborative Learning
The Mobile Host We developed the "Mobile Host", a web services provider for mobile devices A Web Services handler on top of a web server PersonalJava on a SonyEricsson P800 kSOAP2 based requests via HTTP tunneling Footprint of Mobile Host is 130 KB Mobile Web Services for Collaborative Learning

11 Mobile Web Services for Collaborative Learning
Evaluation Simple request-response scenario a standalone Axis-based client accessed services like photo album service location data provisioning service echo, ls, etc. How many clients can be served without preventing user from using her phone in the usual fashion? limit for the number of concurrent participants up to 8 concurrent accesses with response sizes of around 2 KB Mobile Web Services for Collaborative Learning

12 Evaluation (GPS location data)
Mobile Web Services for Collaborative Learning Client and transmission

13 Mobile Host Scenarios for m-learning
Can provide information like pictures audios videos location details The Mobile Host can be used whenever data is pulled from or pushed to a mobile device. Mobile Web Services for Collaborative Learning

14 Mobile Web Services for Collaborative Learning
Conclusion Stressed the importance of collaboration, community building and social networking for learning integration of Web 2.0 concepts and social software in e-learning Explored use of mobile and ubiquitous technologies to enhance collaborative learning activities Presented a smart phone driven Web Services provider Proved Mobile Host feasible in terms of performance Mobile Web Services for Collaborative Learning
