TED talks – Baraniuk on open source

Richard Baraniuk

Listened to a TED talk by Richard Baraniuk (Rice University and founder of Connexions, a platform for open source educational material)

Baraniuk critiques the process of publishing educational materials and suggests a change in practice. He uses an analogy to the music industry as a way of understanding flaws in the current model for educational  publishing and a framework for thinking about a new model. Baraniuk states this aim

‘so want I want to talk about today, is trying to take these ideas, right, that we’ve seen in the musical culture and try to bring these towards reinventing the way we think about writing books, using them , and teaching from them’

A model for open source educational publishing

The music industry model and it’s utility as an analogue to educational publishing can be summarised by the ways content can be created and reused. Specifically the ability to;

  • Create – access to authoring and publication
    • an open source model remove barriers to publication
    • ‘anyone can contribute anything’
  • Rip – copying and reusing material
    • for example, translating educational texts into another language
  • Mix – combining existing material in new ways
    • allows the creation of customised text books based on open source content
    • integrate interactive material to venture beyond traditional model for textbooks
  • Burn – the physical publishing process
    • publish on demand allows for much cheaper physical instantiations of texts by cutting out the middle man
    • the concept of ‘edition’ loses meaning as content is continuously updated

Limitations to the model are discussed specifically technological, legal and quality control concerns. I am more concerned with how our society will react rather than the technical enablers such as XML and as such will limit my response to these domains.

Intellectual property

The issues related to IP in this model are summed up well by Baraniuk;

This is where I told a big lie … because, in fact, I got up here and I talked about how great the music culture is. We can share, rip, mix and burn, but in fact, that’s all illegal. … We would be accused as pirates for doing that.

To enable open source publishing, Baraniuk calls for a IP framework that makes sharing safe and easily understandable, taking inspiration from successful open source software project such as linux.

Creative Commons licences are sited as the solution as they provide a ‘no-nonsense, human readable document, a deed, that tells you exactly what you can do with this content‘. Such licenses allow a legal framework  for distribution, duplication and derivative works, that is ripping and mixing, providing that the original author is attributed. Baraniuk suggests that this legal framework is appropriate for academic and educational publishing on the basis that the motivation of the author is usually to share knowledge and make an impact, as opposed to financial gain.

Quality Control

The statement that ‘anyone can contribute anything’ is hugely powerful and as such, demands great responsibility (Uncle Ben or FDR?).

Baraniuk recounts the story of Kitty Jones, a private music teacher who,

wanted to share her fantastic music content with the world, on how to teach kids how to play music. her material is now used over 600,000 times per month…  …in fact, a lot of this use is coming from United States K through 12 schools because… …as schools scale back, the first thing that’s cut is the music curriculum.

It is reasonable to ask about the author. Who is she, what are her credentials and qualifications? Further, what review process has this work been subjected to? Should our society be satisfied with potential non-experts being invited into our children’s education? Is this pedagogicaly sound?

Baraniuk and Connexions have attempted to address the issues surrounding quality control through implementing social software enabling peer review. Is this enough?

The accompanying powerpoint presentation asks the questions: What is quality? Who decides? Who is the expert?

The social dimension.

Mixing may prove to be one of the most powerful ascpects of open source textbooks. Baraniuk explores the idea of building customised courses supported by equally customised textbooks, mixed from freely available open source content. This will allow us to venture beyond the traditional model for textbooks and include highly interactive applets and siumlations such that textbooks can support learning through exploration.

There’s a social aspect here too.

‘Just providing free content to people has actually been likened by people in the developing world, to a kind of cultural imperialism. That if you don’t empower people with the ability to re-contextualize the material, translate it into their own language, and take ownership of it, it’s not good’.

This plays into the questions of equity, but further, suggests a model for actualising the concept that human knowledge belongs to all humans.

Tomato sauce splash

In our tutorial group for Secondary Teaching Studies, a discussion regarding textbooks took place.

c.f problem in rock climbing guides

  • small market
  • specialised information
  • involves collaborators
  • peer review?

Ella? mentioned a blog describing the battle between California and Texas textbooks (as two of the biggest textbook markets, each state can chooses their own text) and the political / content baggage which is accumulated.

Robert Fitzgerald mentioned the concept of open source textbooks 🙂 social knowledge being shared freely with the society at large. removes barriers to access.

Rock Climber

As a rock climber I find myself buying quite a few guide books. Why? They allow me to arrive at a cliff I’ve never seen before, yet have the information to orient myself, and very quickly and easily find myself climbing a route, which is at the difficulty I desire, with the benefit of the knowledge of those who have climbed it before.

Guide books contain specialised information, often collated from a number of collaborators. It is high stakes information, evidenced by the obligatory disclaimer in the front of most modern guides, ‘Use our information at your own risk’. Guide books inevitably serve only a small market and can be remarkably expensive.

Why is this relevant?

Leading up to a recent climbing trip to Tasmania I was searching for guide books and came across, an online climbing guide to Tasmania.

This wondeful site explains itself:

Basically the position of this guide is that climbing information belongs principally to the climbing community, and that the more freely available it is the better. The most convenient form for distributing information is the web – so all these guide are made freely available on the web. is written by the community, for the community. A beautiful example of open source publishing. The site is based on a wiki platform and is licensed under a Creative Commons attribution – share alike licence, allowing users to freely (and legally) copy, transmit or adapt the information providing they attribute the source. Wow!

What is even better is that their (or should I say, our) guide is of a very high quality, the result of community ownership and rigourous, meaningful peer review.

Must we wait until we’re old … and powerful?

In ELPC tutorial, a comment from …. (sorry I’ll learn your name) regarding the speed of take up of emerging ICT technologies. Perhaps the web will not be fully embraced as a tool for learning in schools until our cohort (or similar) are the ones weilding administrative power. A scary, yet plausible situation.
