We are experiencing a paradigm shift!

http://www.time.com/time/magazine/article/0,9171,1569514,00.html

From Traditional Media to Social Media

• more democracy, less control• it‘s about the user• users are active, contribution is easy• everybody can reach a broad audience• networking, communication• open, public, sharing

Which types of

user generated content

do exist?

Which types of UGC do exist?

• Resources• blogs, wikis • object-centric networks (flickr, youtube)• user-centric networks (facebook, myspace)

• Metadata• tags, comments, ratings…

• helps to filter the abundance of available content• not just anonymous content, gives an understanding

of the individuals who contributed

Why are people

generating content?

How can we encourage them?

Why are people generating content? (How can we encourage them?)

• it’s fun (& it’s easy) adequate interfaces• personal benefit • they like to help• attention• status• rewards• ok, sometimes also altruism ;-)

E-Learning &

User Generated Content

[I won’t talk about ROI and business goals]

Traditional Learning

• delivered by centralized, monolithic systems (LMS)• learner management, not learning management

• specified curriculum, course-centric• has to be completed at a predetermined time• led by an instructor

E-Learning 2.0 [Downes05]

• New users are different• capture information quickly from multiple sources simultaneously• operate at high speed and expect instant responses and

feedback• prefer on-demand access to media• communicate constantly with friends• create their own media

• E-Learning 2.0:• ‘learner-centered’ or ‘student-centered’ design• control of learning is out into the hands of the learners • greater autonomy • emphasis on active learning with creation, communication

and participation

E-Learning 2.0 & User Generated Content

• people use any kind of digital resources to learn • active learning (learning by doing)• people create content available also for others

• resources, conversations, …• people help to filter content

• tags, communication, social browsing

Personal Learning Environments

• not a tool - also not a diagram ;-) • ‘a set of tools, customised to their needs and

preferences inside a single learning environment’[Milligan et al 06]
