Slide 1: The Future of Online Learning and Personal Learning Environments Stephen Downes April 18, 2007

Slide 2: Online Learning • Has been around since 1995 or so • Really grew with the World Wide Web • Has advanced tremendously Many positive developments in the last few years worth sharing…

Slide 3: Open Source Applications • Learning Management Systems such as Moodle, Sakai, Bodington, ATutor • Development and CommunityTools such as LAMS, Connexions, ELGG, Drupal, WordPress • Supporting Software such as Firefox, Thunderbird, OpenOffice, Audacity

Slide 4: Open Educational Resources • MIT’s OpenCourseWare project and the OpenCourseWare Consortium • Open University’s Open Courses • OER initiatives Hewlett, Wellcome, OECD, UNESCO • Creative Commons and CC materials in Flickr, Yahoo, Google, Wikipedia, Wikiversity, etc.

Slide 5: New Environments • Multimedia explosion podcasts, vodcasts, YouTube, Slideshare, more • Mobile computing mobile phones, PDAs, etc. • The 3D web Second Life is a start, we will see more of this

Slide 6: Access… • One-to-one computing such as the Maine laptop project, now spreading rapidly • One Laptop per Child has launched – computers in Nigeria • Wireless access 3G networks, WLAN…

Slide 7: The Internet of 2007 It looks like nothing before… – Like open source – Like Social Networks – Like blogs and blogging – Like wikis and collaborative writing – Like tagging and Digg and… It looks like Web 2.0 Stallman

Slide 8: The Concept… • Learning is centered around the interests of the learner • This learning is immersive – learning by doing • The computer connects the student to the rest of the world

Slide 9: Game Based Learning Types: Branching, Spreadsheet, Game, Lab… =Article&key=1116274375

Slide 10: Workflow (Informal) Learning Types: Community of Practice, Environment, Visualization…

Slide 11: Online Learning at the Crossroads • On the one hand – we have developed tools and systems intended to support traditional classroom based learning • On the other hand – we could (should?) be developing tools and systems to support immersive learning • We should be developing for dynamic, immersive, living systems…

Slide 12: First Iteration: User-Produced Media • Blogs and Blogging • Podcasting and Vodcasting • Game mods and other multimedia

Slide 13: Web 2.0: The Learning Network • The e-Portfolio lives in the intersection between the worlds for education, work, and home • A model for e-Portfolio as a learner- managed construct • Key requirement is easy-to-use tools and hosting services* • *E.g. the “e-Portfolio-as-blog” approach Scott Wilson:

Slide 14: The Idea of the PLE…

Slide 15: Plex Personal Learning Environment Example

Slide 16: Collecting and Filtering RSS

Slide 17: RSS Writr

Slide 18: Edu_RSS Viewer

Slide 19: Edu_RSS 0.2

Slide 20: The Challenge… How to find the right resource… • at the right time • for the right person

Slide 21: The old way – use descriptions • Dublin Core • Learning Object Metadata

Slide 22: The New Way: Recommender Systems The idea is that associations are mapped between: • User profile – properties of given users • Resource profile – properties of the resource • Previous evaluations of other resources

Slide 23: Relations between Entities…

Slide 24: Finding Resources is like Finding Patterns in the Mesh the knowledge is in the network Old: universals – rules – categories New: patterns – patterns – similarities the knowledge is the network Tenenbaum

Slide 25: Pattern Recognition… Gibson

Slide 26: stands for? Hopfield Or is caused by? Distributed Representation = a pattern of connectivity

Slide 28: Where is the PLE?

Slide 29: The way networks learn is the way people learn…

Slide 30: This… Network Learning… • Hebbian associationism • based on concurrency • Back propagation • based on desired outcome • Boltzman • based on ‘settling’, annealing

Slide 31: Leads to This… Personal Learning… To teach is to model and to demonstrate To learn is to practice and reflect

Slide 32: What is the PLE?

Slide 33: We can get an idea of what the PLE looks like by drilling down into the pieces… The question is – how to transport and represent Model models that are actually - conceptual frameworks used? - wiki (wiki API, RSS) - concept maps (SVG, mapping format) - gliffy (SVG?) - reference frameworks - Wikipedia - video / 2L 3D representation – embedded spaces

Slide 34: The question is, how can we connect the Demonstrate learner with the - reference examples community at work? - code library - image samples - thought processes - show experts at work (Chaos Manor) - application - case studies - stories

Slide 35: The question is, how can we enable access to Practice multiple environments that - scaffolded practice support various activities? - game interfaces - sandboxes - job aids - flash cards - cheat sheets - games and simulations - mod kits - mmorpgs

Slide 36: The question is, how can we assist people to see themselves, their practice, in Reflection a mirror? - guided reflection - forms-based input - presentations and seminars - journaling - blogs, wikis - communities - discussion, sharing

Slide 37: People talk about ‘motivation’ – but the real issue here is ownership Choice – Identity - Creativity - simulated or actual environments that present tasks or problems - OpenID, authentication, feature or profile development - Portfolios & creative libraries

Slide 38: Learning Networks Architecture

Slide 39: Downes
