You have to take your hat off to Diane Ravitch

For the last couple of weeks I've been following Diane Ravitch's blog - A site to discuss better education for all in the US.

Diane is an American educational researcher, historian of education, and public intellectual who has held public office for both Republican and Democratic administrations.  She has a prodigious list of publications to her name, and - born before WW II - she is old enough to have experienced and observed the huge changes in US society - including desegregation - from the mid 1950s onwards.  Diane is using her blog to wage an astonishingly energetic personal campaign - averaging 200 posts per month - to protect public education, and to challenge what Pasi Sahlberg memorably calls the GERM (Global Education Reform Movement)  ideology that asserts that schools will improve if there is competition, standardization, school choice, and test-based accountability. If an average of ~5000 page downloads per day is anything to go by, Ravitch is hitting a chord with her readers.

What makes Ravitch's work all the more interesting is that she is someone who has changed her views.

Pseudonymous comments

I've been having an exchange with a commenter  on this blog about psuedonymous comments. My basic position is that substantial comments are much more useful if the identity of the commenter is clear. I do not reject psuedonymous comments out of hand, but would encourage commenters who feel they must obscure their identity from readers of the blog (though not from me) to include in their comment something about themselves - role, area of work, expertise etc - which would help readers situate the comment. If I think the value of a comment is high even without that additional information then I will usually publish the comment. As in this case. I would welcome readers' views on this.

OLPC: Good, Bad or Ugly? Hands-on report by Geoff Stead and the Tribal m-learning team

Olpc3

After all our enthusiasm for the One Laptop Per Child initiative (OLPC) it was amazing to be able to spend the last two weeks testing one out for real (thanks Seb!).

So what is it really like?

The lunch-on-the-move quick read version

We, the Tribal m-learning team think the OLPC X0-1:

  • is inspirational, embedding good educational ideas and collaboration;
  • solves several big technology challenges;
  • is great fun, but pretty slow;
  • is full of first-generation quirks;
  • has an amazingly rich seam of support info on the OLPC wiki;
  • leads the field in several key directions, but might be superceded quite quickly?

One quirk worth mentioning is that almost everyone who tried to open it first time ... couldn't! To avoid this, and other basic blunders we have made a bluffers guide to the OLPC  to be released shortly ...

The sit-down-and-eat longer read version

There are so many competing views and agendas around this little green machine that we felt the best way to review it would be collaboratively. We got the entire Tribal learning technologies team in on the act, including animators, UI designers, teachers, academics and programmers. We also enlisted the real experts: our kids! (aged 6, 9 and 11).

The good:

  • The XO is all about sharing. It has a great visual representation of available local networks, and of the people in your group. This is all about kids doing stuff - and building stuff - together, the collaboration is hard-wired into the system.
  • Seymour Papert lives on. The XO includes great tools (like pippy and turtleart) to help everyone develop basic programming - and from that problem solving skills.
  • The interface is interestingly different, without being counterintuitive ... even for those of us wedded to the Windows / Mac metaphors.
  • The XO includes inspirational technology solutions to many 3rd world equipment problems that until now were ignored by the mainstream, but that we can all benefit from. Things like:
    • good protection from the elements (especially dust and spillage), as well be being very robust;
    • fantastic screens that can even be used in direct sunlight;
    • flexible power use and generation (very low power use, and you can plug it in just about anywhere or even generate your own power by sun or friction);
    • mesh networking: a combination of powerful wireless connections (can travel over 1km!) and ad-hoc networking help get many users sharing a single Internet connection;
    • no license fees, and endless scope to customise the software (thanks to a cut down Linux OS and open source apps);
    • good extensibility, with plug-and-play for standard USB peripherals (useful for an extra mouse and keyboard if you have got grown-up fingers - the keys are tiny!).
  • Useful fold-back screen and mouse / tab controls on the screen casing. What it really cries out for in this mode is a touch screen, though.
  • This device, more than any other we have seen, is all about kids. All about sharing. All about communicating and problem solving - in fact all about learning. OLPC should be a wake-up call for the first world as well ... why aren't we giving our kids the same tools?

The bad:

Slow and Unresponsive. This may sound ungrateful for such a cheap device, but bad responsiveness very quickly becomes a barrier. You can load multiple apps, but with two or three running at the same time the delays between mouse-movements and on-screen responses get so slow that many apps become unusable. Even drawing a single line in Paint results in a series of disconnected bits.

The ugly:

The interface (both software and hardware) suffers from many small irritants that you would hope get resolved in later releases. Individually they are just "quirks", but together they do start to make the "collaborative" nature of the OLPC development more visible. Some of our pet peeves are:

  • The mouse pad: it looks like there are 3 mouse-pads, but only the central one works. You finger has no cue that you have moved onto one of the not-working pads so you keep "loosing your mouse". The pads need raised lines to separate them.
  • The mouse buttons: need to stand out a little more. They are sunk-in, so tricky to use.
  • Integrating with Sugar: the Linux interface being used (called Sugar) lets you access the main menu by moving your mouse to the 4 corners of the screen. A great idea, but several of the bundled apps also use the corners of the screen for menus and icons, which means the menu pops up by mistake when you want to use them!
  • Webcam is off to the side of the screen, so the only way to get your face in shot is to lean over sideways! (Why not put it on top?)
  • Even our veteran Linux developers struggled to find out how to upgrade what. It needs a single application to display all the technical information. For example: hardware version, software version, flash player version, security settings etc. Without this it is very fiddly to upgrade.

Overall we loved the X0 - but want more:

We love the fact it has had so much philanthropic energy put into it, and the bold, exploratory and collaborative ideals it encompasses. But we were frustrated enough with the speed and some of the interface quirks to give it the thumbs down until the next version gets released. If those get sorted, and it gets a touch-screen added, it will be one amazing device!
