Granularity
Big and Little OER
Big Little
Institutional Individual
high reputation cheap
good teaching quality, web (2) native
little reversioning required
easily remixed and reused
expensive low production quality
often not web native reputation ‘buyer beware’
reuse limited distributed
My hypothesis
Granularity is a lens through which we can explore many of the issues around open content

Higher Education as long tail production engine
Should we just stop worrying about sustainability and embrace little OER?
Aggregation and Adaptation
(McAndrew et al 2009):
“In relation to repurposing, initially it was thought:
1. that it was not anyone’s current role to remix and reuse;
2. the content provided on the site was of high quality and so discouraged alteration;
3. there were few examples showing the method and value of remixing;
4. the use of unfamiliar formats (such as XML) meant that users were uncertain how to proceed.”
Little OER tends to
• not be explicit learning content – not generated with the aim of being used for learning;
• not specify the learning that will occur • be easily aggregated into a pathway or framework which
is created by the educator.
The Lamb formula
Do you get different types of learning from aggregation and adaptation?
Implicit Message

When are these different messages appropriate in learning?
Portals and Sites

Specific Project Site Third party site
Advantages Greater brand link Greater traffic
Link through to courses Cheaper
Control Greater serendipity
Ability to conduct research Expertise in social software development
Disadvantages Requires specialist team Can lose service
Requires updating No control eg over downtimes
Lower traffic Loss of ownership of data
More expensive Other non-educational content also present
Should we stop building our own OER sites?
Context
“No amount of creativity in the making of an artefact will compensate for the absence of a framework within which to disseminate it. My Facebook postings (of links to my 2 videos) received brief comments from 3 of my 67 ‘friends’. Nothing on Twitter or Youtube. This demotivated me to continue investing the time. If I’d had, say, a teaching forum with students working on intercultural semiotics, I’d have had more of an impact”

Can educational content survive outside of an educational context?
New ways of working

• Distributed
• Free
• Remix/Adapt
• Multi-media
• = New academic skills?
We’ve only just begun – what other ways of working does open content allow?
Time

Big OER takes time to produce and ‘scrub’
But can be used as is
= Potential big payoff
Little OER is quick to produce
Takes time to aggregate
= Small payoff per item
Can we quantify these pay-offs?
Project
Organisations understand projects, they have responsibility, budget, objectives.

Projects isolate practice
Bottom up/frictionless approach doesn’t fit this model
Can an unproject approach work (particularly in an era of cutbacks)?
ContentContent isn’t everything
But that doesn’t mean it’s nothing
Quick poll
1. Blogs/wikis
2. Quizzes
3. Screencasting
4. Podcasting
When is the personal element appropriate?
