The whole class seems excited and energised by web2.0.  It’s a little like Christmas!  J

But as exciting and empowering as this interactive / integrative technology is, what use is power if you don't know how to wield it?

This is a really good point.  Though I am a little uncertain about calling it “power” – what do you mean by that?  To me it seems more like “tools”.  Then again, I guess you could argue that the tool encapsulates particular potentials and possibilities, and it is those that are the “power” of the tool [in the Latin origin sense of ‘potency’].  Thus knowing what tool to select, how to use it and for what purposes becomes vitally important.  So what are the implication for teaching and learning?  How do we equip learners to choose and use an appropriate tool for their needs?

Yes, I think the power comes from the use of tools.  In the case of our studies it can lie in what you have called "high stakes"reflection, effective communication with tutors, and the networking we do with our peers. Power also resides in the tools we choose for personal organisation, research and transmission of ideas.  I call it power because I am focussing on the product or outcome rather than the process.  We only need to watch the video talk given by Michael Wesch to see that the process of uploading video to you tube, is the tool - but my interpretation is the power is the result, a worldwide audience, new relationships, career making fame or career breaking infamy - if only for 15 minutes.

How can we as educators help our students to make appropriate educational choices about which of these tools with enable their growth and development if we aren't able to make those choices ourselves.

Another good question.  For me, the answer will always come back to purpose – what am I trying to achieve and what best enables me to achieve it?  Perhaps in one learning context social bookmarking is more useful, in another a wiki.  Of course, I am always up for the path we’ve taken in IDEL - let the students loose in the sweetshop and see what they choose for themselves.  :)

Yes as I said needs analysis has never been so important.  I have always used needs analysis in my teaching to discover more about my students: their motivation level, reasons for learning English, preferred learning style, previous experience and exposure. When using technology in the classroom I imagine it would be useful to have a parallel learning technology needs analysis to discover their preferences, current knowledge base, research interests, organisational ability, and even basics like computer access at home, internet speed and keyboard skills.

Me and choices don't sit well together.

And how well do you and no choices sit together?  :)

Valid point.  :D

The pic you’ve included is fascinating – are you suggesting the web2.0 services are broken scraps and leftovers that only work when they come together?

The image is (I am sure you know) M.C. Escher's 'Order and Chaos' I chose it to illustrate how for me, the two are still side by side, the order being far more beautiful, but yet there is humanity in the chaos.  Interestingly Escher chose as chaos human detritus; the jetsam of everyday life, as opposed to natural flotsam twigs, bones, leaves etc.  And the order is represented by a crystal.  It is a more natural symbol, but still faceted and therefore imposed or 'tooled'.  But imposed by whom? It could be human - but I see a more supernatural quality in it.  It is no man-made diamond, but an uncanny supernatural thing (a star in a sphere).  Escher spoke the language of geometry and mathematics so I suppose his order comes from the laws of maths and physics.  I am hoping for divine intervention - deus ex machina? Or more probably synergy of connectedness.  I hope by participating in web2.0 technolgies the world and I will come to some agreement on a portfolio of tools which will survive the intitial flurry of early adoption and avoid the crash and burn of fad-death. Yes this portfolio will be in constant flux, but by careful selection I would like to think I can choose (for myself and with my students) tools that will be relied on to have value now AND in the future.

One final thought, in Escher's image chaos finds itself reflected in order - maybe that is all we need order for, chaos is infinitely more creative and inspiring, but sometimes we need order to act as a mirror, a reflective devise to organise the chaos into something we can use.
