The vision

Vision needed on many levels:• National• Institutional• Personal

ODL policy making and implementation: vision & reality

The outcome

Tapestry by ‘Suddenlysheturned’ on FlickrThreads represent landscape of ODL in 21st century

The design

Turning vision into reality through designThe clearer our vision, the easier it is

Presentation about the elements that go into that design

The infrastructure

Low-bandwidth infrastructure can enable a beautiful productKey is to tailor the design to the nature of the infrastructure

The action

• Threads show key characteristics of landscape of ODL in 21st century

•We need to respond in appropriate ways

This is where the action’s at!

Tutors/ trainers and learners are all in this together

Emerging technologies

We need to take back control!

Not only for

digital natives...

Take some time to play...

The ‘low bandwidth’ option...

• Huge proportion of our learners have cell phones•UNISA – using MXit for

learner support• Mobile phones for podcasts•SA can lead the way here

Social learning

• Sub-theme: integration of ICT and social networking• Henning & vd Westhuizen (2004) – ‘The social context becomes the facilitator & the scaffold for e-learning’

Learning in communities

of practiceMany learners use ‘unofficial’ social

networks

Fuzzy boundaries

•Crossing borders – geographically, culturally, across disciplines•Maggie’s community: Ireland, India, Philippines, Puerto Rico, China, Egypt, New Zealand, US Minor Outlying Islands...

From Pretoria to Khartoum...

J. Cronje (2006) – Sudan Uni of Science & TechnologyRohleder et al (2004) – UWC and SUN – diversity

OERs

Don’t reinvent when you can mix up or mash up!

Extracting DNA from bananas

Rapid information flow

Problem for everyone, especially teachers with

large class sizes

Manage it; don’t drown in it!

Scanning

Filtering

Making connections

Synthesising

Conversations about learning

Asking questions, thinking, writing (blogging?), going publicExplore students’ perceptions of online learning

Reflective practice...

International move towards a more constructivist approach to ODL

The sum of the whole...

... is greater than the parts.
