Has the dream of cheap computers + FOSS for the disadvantaged evaporated?

What Rangan Srikhanta, who formerly distributed OLPCs in Australia is doing now:
  • Not a cheap laptop
  • Not free and open source software
One Education

Their infinity computer sells for $380 + GST. What happened to the dream to make a laptop for kids for $100?

His initial plan was to make a modular computer that kids could put together and to have multiple OS: Linux / Android as well as Windows. But then Microsoft intervened....
"What happened to the modular infinity?"

"... the short story is that Microsoft put us in touch with manufacturers that could make the Infinity:Concept a reality"

"We are currently working to get both Android and Linux supported on the Infinity:One! Our aim is to provide your choice of operating system, and Windows 10 is just the beginning"
- FAQs
Promises, promises ...
"We’re not there yet, but we’re working towards it. The road to Infinity begins with the Infinity:One - join us on our mission to make the world a better place for children through technology."
- Concept page
Contrast what has happened with this 2015 interview of Rangan:
This week, the Australian 15-employee One Education will announce its new generation low-cost computer. A Lego-like modular PC-and-tablet in one that can be assembled by a four-year-old, updated as components reach their end of life, and repaired in the classroom.to last their primary years

Its main components - screen, battery, keyboard, CPU, camera, Wi-Fi connection - are separate parts of the puzzle, with the main bits concealed under a soft silicon cover. A trade scheme will allow schools to swap parts as the technology evolves and students' needs change.

The XO-Infinity is only a prototype thus far.The first working model is due in August, the first shipment early next year.
- Meet Rangan Srikhanta, the former refugee who wants to change the world one laptop at a time
Update (Oct 9, 2017)
Received this mail from Tony Forster:
I see the Infinity one in a similar light as OLPC's XO Android tablet as a bid to 'stay in the game' while cheap tablets and phones undercut the OLPC business model.

The smartphone is the hardware that now best fits the OLPC concept:
"provide educational opportunities for the world's most isolated and poorest children by giving each child a rugged, low-cost, low-power, connected laptop"
I think that Sugar's bid to control the OS or Desktop failed and the best thing to do is work with the user's choice of OS, be it Linux, Android or Windows and provide good free open source educational software to run on these platforms.

Specifically I would like to see a drag and drop programming app for Android that is optimised for a small touch screen.

OLPC's XO-3 tablet

"if it works"

It sounds too good to be true that Nicholas Negroponte could deliver on both the most amazing computer hardware and also the holy grail of education - teaching reading without adult help. I would love to hear more detail about this software based adaptable reading program from anyone who knows more.
As part of a two-year project to study educational development among young children in developing countries, researchers will collect data from XO-3 tablets used by three-to-eight-year-olds in India, Tanzania and Sierra Leone. Software on the tablets will record audio and video and adapt a reading platform to the needs of the children without human intervention. The project will study how children interact with the tablet and will aid in the study of tools for self-learning and critical thinking among children. One goal is to provide basic comprehension and reading, which is important in countries where teacher training is inadequate.

"In the reading experiment, where we ask can a child learn to read on his or her own, we imagine many hours of use per day, as many as six or eight. Frankly, the reading experiment may be the most important thing I have ever done....if it works," Negroponte said.
- OLPC's XO-3 tablet to debut at CES
Footnote:
I looked up an old blog where alan kay said something about this during his 40th anniversary of the dynabook speech:
BUT, when Nicholas started up the OLPC project my heart sank, even as I supported it ... because if it's tough to get good mentors in the USA then it's really tough out in the Third World ... no user interace today can find out who its user is, what its user knows, what it can do ... it can't find out what level of reading the user can do and help find out the next level of reading

the xo is not a netbook


Interesting that Negroponte doesn't like the netbook name applied to the xo (at 7:55)

The word Netbook is a portmanteu of the words internet and notebook. But the xo is intended to also be a machine containing a wide variety of educational software which can also be used in situations where children don't have internet access.

Negroponte: "Kids in Ethiopia don't have the internet in a nearby cloud ..."

I think the way we name things is important so I checked some of the names that have been used for these machines:
  • netbook
  • smartbook
  • MID
  • thin-and-light
  • low cost small notebook PC
  • low cost ultra-portable notebook computers (Microsoft mouthful)
  • ultra-portable
  • mini notebooks
Most of these names focus too much on physical characteristics. xo symbolising a childrens machine is superior:

update (5th July): Here is a an attempt to classify the suggested names of these computers by their functionality and purpose or their failure to do that

PURPOSE
Childrens Machine
xo

FUNCTION
Connection Machine
Dynabook
smartbook

TECHNO CENTRIC
netbook
MID
thin-and-light
low cost small notebook PC
low cost ultra-portable notebook computers (Microsoft mouthful)
ultra-portable
mini notebooks

Schwarzenegger terminates textbooks

California's Governor Schwarzenegger has announced a digital textbooks initiative.
"The first phase will bring high school math and science classes access to free digital textbooks by fall 2009 - with additional content to follow"
One of the spins on this, from the video, was "flexbooks" rather than textbooks, the interactive potential. Schwarzenegger mentioned various positives but he mainly stressed the saving of money in the worst economic times since the Great Depression:
The average textbook costs about $75 to $100 per student. For a school district with about 10,000 high school students, the use of free digital textbooks in just science and math classes could save up to $2 million dollars
It wasn't mentioned that the seed for this idea was planted in part by the OLPC:

OLPC Nepal Project overview

Randal Schwartz interviews Bryan Berry, of Open Learning Exchange Nepal, the NGO implementing the OLPC project in Nepal
http://twit.tv/floss66

I've transcribed a substantial portion of this interview below, rough notes only, without comment at this stage. Numbering is just for id purposes if people want to discuss particular points.

Skip to 12:45 minutes to avoid the chatter and google summer of code adverts at the start

1) Bryan Berry, CTO Open Learning Exchange, Nepal

2) Describes geography, weather, population

3) 6 million kids in Nepal need education – how can we do it? Education makes all the difference

4) Literacy about 45%, young people 80%

5) There are hardly any libraries, even in Kathmandu (the largest city in Nepal) – most peoples parents are illiterate or barely educated, there aren't any books at home

6) teaching method is that teacher speaks and the kids repeat – one teacher for 50 kids – teachers are doing their best but they have almost no resources

7) problem with rote learning
example of a kid knowing that 2+1 = 3 but not knowing what 1+2 equals ...

8) OLPC project provides opportunity of putting a lot more resources into the hands of kids and teachers

9) xo described, I skipped this bit

10) Open Source software critical to high quality education – education has to be very customised, to the kids, the teacher, the environment and the country – not something you can design in New York city and will fit another country

11) In the OS community we know that through the iterative process of other people looking at your code / work they can make it better – and that's true for education as well

Q) What kind of customization had to happen to the software for your particular project?

12) Problem of rendering Nepali properly – very little support across different applications

13) Had to conform to the Nepali national student curriculum – absolutely critical

14) 99% of teachers care about their kids, want them to learn and don't want their kids to fail their exams at the end of the year – if their kids fail they are set back a year – they have to make sure their kids don't fail that exam – it is a standards based curriculum

15) So we created a whole set of learning activities which conform to the national curriculum

16) transitions in what program to use to develop curriculum content and the reasons why (etoys --> flash --> HTML5 + javascript)

17) etoys
started off doing the curriculum in etoys / squeak – first 6 months
problems:
  • performance
  • very small community doing what we were doing
  • squeak programmers are smart people who tend to move onto something else, eg. PhD
18) flash
flash is a great technology but run time is proprietary, unfortunately (considered using gnash but that created some stability and performance issues) – we release our code under the mit license

19) HTML5 + javascript
Way to go because there are a lot of community people who use those tools, there is a lot of momentum in that area - proprietary code is really baked into education but if you use javascript and HTML you almost can't keep your stuff proprietary – it creates a virtuous feedback cycle as in the AJAX community where releasing your source is good for the whole community

20) Open Learning Exchange (OLE) Nepal
Nepali led organisation, led by Rabi Karmacharya; 30 people - full time some part time; non profit; team of developers; teachers working together with developers; teachers are creative, know how to engage the children

21) Once we showed the teachers learning activities then they welcomed it with open arms; Nepali government is very supportive

Q) How has this changed the classroom from the teacher speaks, student repeats?

22) The xo frees up the teacher to interact more individually with kids

23) Sugar UI has collaboration baked in

24) History of xo in Nepal
Started with 150 laptops to two poor schools in April 2008 just outside Kathmandu to 7th Graders and 2nd Graders (?). Worries about misuse did not eventuate, the kids treated their laptops like gold (they don't have possession of their own)

25) 1:1 ratio critical; take home (core principles)

26) Cultural difference with USA, Nepal kids want to become engineers and doctors, not pop stars and baseball players; they don't say maths sucks or maths is boring; they are excited about learning

27) Internet connection issues discussed (skipped this)

28) Email can only be done with web mail such as gmail. More needs to be done on the server side, hard to complete everything in such a complex project

29) We can always find someone to fix the hardware but training someone to master the linux command line is harder

30) The server has to be as simple as possible

31) If there is a problem with the xo there is a firmware tool called testall which can test all the hardware

Q) Do you have objective numbers on performance?

32) If we teach to the test then test results will improve. Walter Bender has said that the hard part about education is that you have to wait 20 years. However, assessment is important in terms of justifying the expense of what we are doing.

33) Expanding this year to 2500 laptops (cf. 150 laptops last year) to geographically dispersed settlements representing the breadth of life in Nepal

34) The huge challenge is to grow the support organisation to support the deployment

35) Running a grassroots volunteer organisation is very hard. You have to find the people who are really serious as distinct from those who are curious but temporary supporters – people who want to chat and visit but who are not prepared to do the hard grunt work

36) It is not like online FOSS which has an automatic barrier to entry which filters out those who are not really interested

37) Parents want books – digital books! They equate education with books

38) There is enthusiasm for FLOSS in Nepal – Nepal won best software freedom day 2 years in a row from FSF. But there is not much open source software being developed.

39) Those who could be developers have little free time. Kids here have to study hard and have extensive family commitments (far more so than we have in the west)

40) Main funding for the project came from the Danish Embassy

41) OLPCs were donated by Swift organisation, a Banking co-operative (European Banks)

42) Raising money for the laptops, although the largest cost, is the easiest part of the funding

43) The hardest part is building the support organisation and developing curriculum content

44) Kids keep the laptops at the end of the year

45) Wade Brainerd has developed a great typing tutor, called typing turtle

46) etoys is a fantastic environment but requires a high degree of dexterity with the touch pad, the drag and drop features – the teachers really struggled with that

47) A key thing we need to do is to tie lesson plans into working with programs like etoys and turtle art – teachers are busy if it's not part of the curriculum then its likely to not happen

48) Education is the central thing for poor countries to move out of poverty – but it takes a long time to build up

Q) What was the biggest hurdle or hurdles?

49) You have to create a firewall between the local company (OLENepal) and the FOSS community. Early on some people saw it as their personal project and that was very detrimental – once money becomes involved – it was ugly – this is why we formed OLENepal as a separate organisation

50) Create local content first – before the flyers, before government meeting – develop local content in their own language

51) Linux supports Nepali, Microsoft doesn't

52) If Bryan had more money he would focus on building digital content (K-12) before laptops – once there was this content then everyone would buy laptops

thoughts about OLPC cutbacks

Some thoughts about the OLPC project cutting back on 50% of their staff (refocusing on our mission)

When this happens the prophets of doom, such as wayan vota (olpc just got gutted) and arstechnia (OLPC downsizes ...) publish quickly and with a tendency to sensationalise and catastrophise. We are all familiar with this style of journalism.

This really is a 40 year story going back to when alan kay first envisaged the dynabook. We need to take a long term view. It is also a good time to revisit Walter Bender’s 23 questions which is another insightful way of viewing the big picture

The Surface Mission is to bring education to the children of the Developing world using the XO as a vehicle. This is a serious and realistic although a very hard to achieve goal.

The XO-1 has been a partial success. However, it did not achieve its initial (problematic) goal of selling to the Developing world governments in millions. Clearly, the stakeholders are not satisfied and cutbacks have now occurred. Also the 2008 give one, get one was a relative flop, with only 7% of the sales of the G1G1 in 2007 (source). But Negroponte keeps pushing forward. The dual screen XO-2 (article) may achieve the scaling that was hoped for but did not eventuate with XO-1.

Sugar, the new OS, has been a partial success. It is diverse, free (FLOSS) educational software with unique built in (when sugarized) collaboration features. But some / many aspects of Sugar are buggy and / or unfinished. There is still a lot of work to do.

All of this does spin off in multiple directions – Walter’s question categories are Computer Science, Engineering, Education, Economics and Social Sciences. There was some discussion about his 23 questions at OLPC_news (comments). It would be good to see more.

Different people bring different skills and expertise to the Project. Everyone who has been involved with it has been broadened and deepened in some way. No regrets. I'm not aware of anyone who has been involved who wishes that they hadn't been.

There may or may not be ultimate success. But there is ongoing partial success as the consciousness of every participant, adult or child, of the social possibilities of disruptive technology is increased.

One aspect is that the Projects are in more or less constant turmoil. I see this as inevitable.

We have cutting edge, complicated, disruptive technology – hardware and software.

We have a difficult, hard to answer social question: How best to help the impoverished children of the Developing world?

We have conflict between FLOSS and Proprietary pathways. Can FLOSS alone deliver the goods?

We have division between expert and non expert enthusiasts in different areas. Some fields demand democracy and transparency, eg. FLOSS. But even FLOSS has benevolent dictators as a concession to expertise. But in some other areas democracy is frankly a waste of time. For example, there is little point in Mary Lou Jepson consulting with non experts about the latest in screen technology. This can be extrapolated, more or less, to many other parts of the Development process.

We have conflict over the best methods to educate children. Constructionism is not well understood and is not the only path.

How much should local issues influence global development? (refer to the Bryan Berry thread on Its An Education Project)

How do hardware experts, software experts and educators work together effectively to produce a better product?

There is limited money and people to carry out this project. Even though a Keynsian approach – spend money on public works to increase employment - in economic crisis would suggest generous funding for this project. Sounds like a good idea but I doubt that it will happen.

We have entrenched, powerful interests who are threatened by these developments (Intel, Microsoft, educational bureaucracies, existing NGOs)

How could there not be continual turmoil?

At any rate, the XO / Sugar Labs projects continue to be excellent objects to think with and to act through. In the words of David Farning:
"I would like to offer a _heart_felt_ thanks to everyone at One Laptop Per Child who has made Sugar and the XO the products that they are today.

You still are at the forefront of a revolution in learning such as the world has not seen since the invention of the printing press.

But, this revolution, as with all revolutions, is hard to plan; there are no maps, there is no rule book, there is no gray bearded sage to guide your way"
The xo and sugar labs will continue to transform the world for the better. By just how much remains to be seen.

Bryan Berry's Nepal XO notes

Notes from Nepal’s OLPC Deployments

Bryan Berry raises some important points and conjectures. It is best to read his original, (I left a comment there)

1) Manual dexterity block point
"While the teachers learned how to use the XO very quickly, I miscalculated how difficult certain actions would be for them. Specifically, it took them a while to learn “dragging and dropping” with the touchpad. Many of the best activities on the XO require serious dexterity with the touchpad such as TurtleArt, Etoys, and Scratch. For this reason we couldn’t cover these activities during training. I recommend starting teacher training with activities that do not require a lot of dexterity with the touchpad"
2) What the curriculum demands
In OLPC-land we like to talk about lofty concepts such as constructionism, co-learning, collaboration, etc. Meanwhile, teachers at Bashuki and Vishwamitra have more pressing concerns. The Nepali system does not practice social promotion. Children have to pass year-end examinations to move on to the next grade. Nepali teachers are interested in constructionism, co-learning, and collaboration as long as they don’t hinder their students progress through the educational system. Our teachers are quite happy with the E-Paath suite of educational activities that OLE Nepal developed in accordance with the national curriculum. The real attraction of OLPC for teachers is that in class they can task students with a problem on the XO and then spend much of the period working with students that need help
3) Top Requests from Teachers and Kids
  • Easier way to play music and video
  • A better E-Book reader
  • A lot more activities for learning English
  • All the Nepali textbooks in digital format
  • A comprehensive digital library with lots of Nepali-language reading materials
  • A Typing Tutor program for learning English and Nepali
  • Interactive learning activities that match the Nepali curriculum
  • A car racing game (the kids)
and other very interesting points in his article as well:
  • amazing enthusiasm from teachers
  • ability of XO to diagnose if any particular hardware component has failed (“test-all” command in the XO’s OpenFirmware)
  • it is feasible to train teachers how to fix hardware problems but more difficult to teach them how to fix software problems in the linux kernel or within Sugar
  • The XS (school server) has improved under the leadership of XS architect Martin Langhoff
  • XO project in Nepal expanding to 15-20 schools in 5-6 districts in April 2009

poverty and OLPC affordability

Apart from Australia and DR Congo (included as benchmarks) the following are most of countries to which the OLPC has already been deployed in significant numbers or to which there are reported plans for significant deployments in the near future. The figures are in Purchasing Power Parity PPP$ (adjusted income per person) of selected countries. The data is from the Gapminder site [1]

COUNTRY PPP$
USA 31,133
Australia 24,219
Uruguay 8,653
Mexico 7,762
Columbia 5,877
Peru 4,670
Papua New Guinea 1869
Ghana 1515
Mongolia 1285
Mali 1084
Nepal 1052
Rwanda 983
Ethiopia 824
Afghanistan 740
Haiti 709
DR Congo (poorest) 230


Here are some figures of the numbers of XOs deployed to some of these countries [2] [3]:

COUNTRY NUMBER OF XOs
Uruguay 130,000
Peru 70,000
Mexico 50,000
Birmingham, USA 10,000

Colombia is reported to be about to buy 20,000 and Ghana is reported to be about to buy 10,000.

In addition, Ethiopia, Rwanda, Haiti, Mongolia, Afghanistan have approx 5,000 XOs each provided by the Give1-Get1 program.

So far, the governments which have purchased large quantities (not just pilots and not recipients of the G1G1 – Give one, Get one - scheme) of XO’s are Uruguay, Peru and Mexico.

These Latin American countries are not the poorest in the world. Many African countries are the poorest along with some Asian countries. These countries are roughly 5-10x poorer than those which have actually purchased the OLPC

Each OLPC or XO costs about $180 per person. The Total Cost of Ownership is higher and has been estimated at about $450 over a five year period (disputed figure)

Apart from OLPC, other possible information technologies come to mind for poor countries, which are being used for education:

OMPT (one media player per teacher) - One portable media player with speakers and power source costs as little as $50. This small cost can change a classroom of 40 or 50 individual lives

Mobile phones - for example, see the MobileED project

Telecenters - "I found computers in all the centers, but bicycles, books, cell phones, community radio stations, and video tapes were also used to obtain and share information" (olpc-news article by Robert Kozma)

Internet Kiosks - A day in the life of a village kiosk operator in India

I am not suggesting that the OLPC is not a great technology for the poor children of the world. They need personal computers for maximum benefit. But due to the economic bottom line for some countries at the moment it is too much to expect that they will get there without assistance. Also we need to consider transition technologies like the above to bridge the gap.

Another related issue is the best method(s) of electricity generation for poor countries. This is held over for another article.

alan kay: after 40 years the dynabook is not here yet

video Personal Computing: Historic Beginnings

I have transcribed a section of Alan Kay's recent presentation marking "40 years anniversary of the dynabook" because I see it as an important contribution to ongoing discussions about the significance and prospects for the XO, or OLPC

Alan Kay visited Seymour Papert in 1968

49 minutes: Slide that involves Alan Kay

About 40 years ago I went to visit Seymour Papert... because I had started to visit people who could be users of a desktop computer ... and Seymour was working with children ... Seymour was a mathematician who had worked with Piaget ... (talks about Seymour's tragic accident from which he has not recovered) ...

Kay's interpretation of Seymour's work: Children are egocentric in a charming way ...they do everything relative to them ... so if they were a co-ordinate system they would be an inertial co-ordinate system ... and an inertial co-ordinate system is the differential geometry of Gauss ... and if you keep track of this in the right way you get the differential geometry of vectors ... and a child is one of those vectors... and so is the turtle ... and he thought, boy(!), this is so close to the way children think already I wonder what would happen if we put some formalism on it and treat it as mathematics

So ask a little kid to draw a circle with their body and ask them what they are doing ... they say they are going a little and then turning a little, over and over

In logo: repeat 360 [forward 1 right 1]

Tell the turtle to do that ... and by golly you get a circle and you can put in different values to get circles of different sizes ... and so we have a differential equation here which is infinitely simpler than (traditional) differential geometry and which can be understood by a young child

This completely blew my mind! Once you've got something which is incredibly powerful that a child can learn you've no longer got an adult tool ... you've actually got something like a printing press that is one of the great 500 year inventions in human history

If children can learn these powerful ideas then you have a chance to not just increment on what is already known ... they will actually help over several generations to invent something new

So, that combined with just seeing this flat panel display with all these wise words of McLuhans in my mind (mentioned earlier in talk) on the plane back to Utah after meeting Seymour I drew this little cartoon with kids out in the grass ...

... because if you are going to make a personal computer for kids don't put it on a desk ... that isn't them ... so I immediately took the fun idea of a flat screen computer and made it paramount ... you had to make a computer that was in every way made for a child, that they could take away from adults and learn by themselves ... it would have to have wireless, a stylus, a touch screen, a keyboard (because even perfect character recognition is not fast enough to do bulk typing), removable memory ... and so all of those things coalesced ....

(describes how he made the model from a cardboard box)



Alan Kay's definition of portability ... that you can carry something else as well as the portable device ... arrived at the figure of two pounds (which is roughly 1kg)

(some information about head mounted display and a wrist detector by Negroponte left out here)

If you think about this as a service idea then what are the actual services ... (stuff snipped) ...

"IT'S NOT THE TECHNOLOGY, STUPID"

You really have to have some idea of the end users ... leads into new slide



DYNABOOK PLAN

It's a service idea with serious goals about education, especially self education

Kept (?) standards: Fluency in powerful ideas for > 90% of children

powerful ideas and how to learn them ...

CONTENT

... and with the aid of computing media


Human mentors

MENTORING

Computer mentors

[[Alan refers to these, here and later, as "four ideas", which I understand to be:
  1. What are powerful ideas?
  2. How can they be learned with the aid of computing media?
  3. Can this work with human mentors?
  4. Can it work with computing mentors?]]

I was interested in whether we could make computer mentors because my confidence in adults was very low back then ... and still is. The biggest bottleneck to education reform is the adults that are in the system

In the Third World it is the lack of adults ... But in our world it's almost the lack of adults ... almost no elementary school teachers understand anything about maths and science ... in a way things might be almost better if they weren't there because the children would not be getting misinformation about it

It has to be setup to succeed for 90% of the children, not just the 10% who are naturally good at it

The problem with technologists doing it is that we are all setup by nature to be good at it ... all of us here learnt to program within a weeek ... I'll bet you anything ... it's not that hard if you almost know what it is ... but if you don't almost know what it is, it can be really daunting

This is why computing people generally design terrible computing user interfaces ... they're not only willing to cope with something bad, they are pleased to ... because it's a little challenge for them ....
(this section finished at 1 hr 1 min)

At 1hr 15min the moderator asks:
"Why was the dynabook never built in spite of all these people trying to make it happen?"
Alan recapitulates the four ideas outlined above ... then ...

Working on the first two with our 90% success threshold ... led to 25 years of failure ... we were paying for this research ourselves ... nobody would fund the children's research because we did these long projects ... we didn't believe in most forms of testing that are reported in the education literature ... so we wanted to convince ourselves that the children were getting fluent and that 90% of them were getting fluent ... by those sorts of criteria it was one failure after another .... but after each failure we would learn something

And about 10 years ago one of the systems that we did started teaching many more children with adult help in a much stronger way (I think he means etoys) ... so I think after 40 years the first two ideas and a little bit of what sort of human mentoring you need have been solved ...

BUT, when Nicholas started up the OLPC project my heart sank, even as I supported it ... because if it's tough to get good mentors in the USA then it's really tough out in the Third World ... no user interace today can find out who its user is, what its user knows, what it can do ... it can't find out what level of reading the user can do and help find out the next level of reading

There is common sense in the world concept ... so we make a world populated with objects ... but they didn't interfere with the user strongly

That isn't enough ... pure discovery learning took us 100,000 years to get to science ... so you need learning that is facilitated ... and if you can't make thousands of good teachers in a year then you have to have an interactive user interface to save yourself

This dream of having a UI to facilitate is as old as AI ... it is AI ... if we had this we could make up for no teachers and bad teachers (but we still need good teachers) ... so when the OLPC project started I thought OMG, we are lacking the one piece of the technology ... if we could just ship that machine with a program that could teach children to read in their native language ... that would be the killer app and we wouldn't have to worry about anything else for a number of years ... but that technology doesn't exist ... it is that gap which has to be bridged in order to fulfil the educational goals that the dynabook has ... you have to have a way to get around the adults in the system that make educational reform difficult

OLPC: give one, get one, australia

Last time around this was only available in the USA and Canada, from memory

This time you can give one get one in a whole host of countries (44+ in this article) and this now includes Australia, through the OLPC-australia organisation

Contact information

Give 1, Get 1 explained
"Purchase two XO laptops. Give one to a needy child in remote Australia or the Pacific. The other is yours to give to a child in your life"

Purchase form

With the fall in the Australian dollar the cost would be something like AUD$700 ($468.95USD), according to this OLPCnews article

update 7th December:
They are charging $399 for a laptop, with the profits going towards OLPC-AU projects


update 8th December:
Wayan Vota has corrected the above information, the total cost for one is $468.95

I did an order simulation on the olpc-au site and the extra charges are:
GST $20
Shipping and Handling $40
Transaction Fee $10

I also notice that it is not a Give one, Get one scheme because if you order two the price just doubles to a whopping $927.90

40th anniversary of the dynabook



Alan Kay, Chuck Thacker, Mary Lou Jepsen and Steve Hamm (moderator) at the Computer History Museum (one hour 45 minutes), 5th November, 2008

Alan Kay outlines the history from 1958 (John McCarthy) through the personalities and inventions to circa 1972

The Dynabook plan (not yet realised):
  1. What are powerful ideas?
  2. How can they be learned with the aid of computing media?
  3. Can this work with human mentors?
  4. Can it work with computing mentors?
Alan Kay at 1:15
Points 1, 2 and 3 above have been solved partially but not yet point 4. Hence, there is a problem in deploying to the third world, since the teachers are not there in sufficient quantity or quality

disability access to laptops is also a hardware design issue

Janet told me that David Wallace wanted to check out something on the XO. "Who is David Wallace?". I was informed he was a quadriplegic and blogger. Here is David's About Me.

Before the visit I read an earlier blog David had written about how his hopes for disability access to laptops had been raised on using an early model of the XO: Lifekludger with the OLPC

But I didn't really begin to understand the issues David was raising until I visited him at his home and he explained it to me

The main issue is touch, more specifically touch with skin, that nearly all laptops / mobile devices are not catering for people who can't touch a touch pad or a screen with their finger

I had no idea. That is, no idea of the requirement of skin to make a touchpad respond. With a finger the pointer moves easily. But when I scrapped with the back of a pen over the touch pad and stylus area nothing at all happened. The things we don't notice.

David wanted to check out the stylus function but unfortunately stylus development seems to have been discontinued. A phone call to Joel confirmed that. The picture below shows what was intended initially but as I say the stylus development has been discontinued.


Once again I had no idea about the importance of the design of hardware, not just software, for people without the ability to touch with the skin. I've since read a few of David's blogs and will try to summarise some of the key points below:
  • need for an input pad that doesn't require using a finger, a dual touch pad that responds to both finger and stylus
  • need for a track-point pointing device on the XO
  • need for a key-modifier program to hold the shift, alt, fn keys while hitting another key (’sticky-key’ software that emulates two or more finger presses on a keyboard)
  • need for a push for accessibility guidelines or standards in hardware design
  • Voice recognition software thats good for dictation may not be great for software control, and vice versa
  • plugging in a trackball to a laptop defeats the purpose of the compact, portable nature of a laptop
  • attempts have been made to develop "touch pencils" but they have not been successful

interviewed by Phil and Belinda

Recently, Phil and Belinda, two Flinders University education students visited my year 10 class, interacted with the students and after lesson interviewed me. It was for a project for a Digital Media course run by Trudy Sweeney who is also currently President of the Computers in Education Group of South Australia (CEGSA)

The questions were about Scratch, learning environments, etoys and the OLPC. The interview goes for about 30 minutes and is available as an mp3 on this page (also available as smaller question length segments)

Belinda and Phil's whole project about Squeak, Scratch and Etoys is available here

I was impressed by Belinda's ideas for using Scratch to teach Japanese and Phil's expert linux knowledge - and the fact that he went to an anti digital censorship campaign back in the Senator Harradine moral crusade days when he (Phil) was 15 yo! (unfortunately we now have new moral crusaders pushing the same barrow today)

total cost of ownership: XO versus computer lab

Tony Anderson published his calculations for total cost of ownership of an XO compared with a computer lab in a long and sometimes acrimonious thread on olpc news:

his results:
OLPC: 4.5 cents per hour
computer lab: $2 per computer access hour

If he's correct then that's 40 times more value for money roughly speaking :-)

Here are his calculations:
Surprise! TCO for XOs in schools is $437.50 (4.5 cents per hour)

I have attempted to recalculate the TCO based on a more realistic description of the OLPC model, but using the numbers in the report.

The TCO model in the report is based on teaching ICT in a public secondary school. The purpose of this training is to prepare university-bound students to enter a course of study leading to a position in the computer field. Assume that the school enrollment is 160 students. The study assumes 3.5 hours lab time per day, 5 days per week, for 39 weeks per year (10920 available hours per year). Shared among 160 students for an average of 68.25 hours per year per student or 1.75 computer access hours per week.

The OLPC model is based on each child having an XO throughout the class day and at home on evenings, weekends and holidays. It is also focused on primary school education. Assuming a school of 160 students, at least 160 XOs will be needed. Assume a steady-state situation in which each child entering the school in the second grade gets an XO. Each child keeps his XO throughout the primary years (grades 2 thru 5 as assumed in the study). The school purchases an additional 5 XOs per class to provide for loss, damage, repair, incoming transfers, and the teacher. In addition the OLPC model assumes a dedicated computer (XS) per school which provides internet access, provides backup for the XOs, caches instructional materials, and supports a CMS (Moodle). Each child has a computer which could be used each day for six hours in class and two hours at home (plus ten hours on weekends). This is approximately 1800 hours per year - let's assume 1000 hours.

First, look at the direct computer cost, excluding initial setup, training, connectivity to the internet, electricity, and Tier 1 (software) support.

Case 1: Public Secondary School (grades 9-12) sets up a computer lab with 16 desktops (one is also a server) to teach ICT. The total cost is $8000 with a per seat cost of $125. This is a approximately $0.40 per hour for computer access ($125/312).

Case 2: Public Primary School (2-5) provides each child and four teachers with an XO. The initial purchase for this school is 160 + 4 (teachers) + 4 (reserve) for a rounded-up total of 170 at $200 each ($34000). The annual buy is 45 laptops at $200 per student ($9000). A dedicated server per school costs $500 (headless mainstream desktop). This is a total cost of $34500 ($216 per student). If we assume utilization of 1000 hours per year, the cost is($216/4000) or 5 cents per hour. Note: if leaving students keep their XO, the cost in the first four years is $34000 + $27000 (3 * $9000).

Other costs:

Case 1 the computer lab pays $33886 total for initial setup ($5351), training ($10620), software support ($10920), hardware support ($2432), electricity and internet connectivity ($5351), and damage and theft ($2640). This increases the computer lab cost to $2500 (41886/16) per seat and approximately $2 per computer access hour ($41886/16/4/312).

In case 2, the costs of Tier 2 and 3 (hardware maintenance) and the costs of damage and repair are handled by purchasing extra XOs. In the OLPC case the extra cost is $28314 (excluding $5072). The OLPC total cost is $70000 ($41500 + $28316). This is $437.50 per student or 4.5 cents per hour.

Evaluation of OLPC Project Nepal

Formative Evaluation of OLPC Project Nepal: A Summary (June-August 2008)
author: Mr. Uttam Sharma, a doctoral student at at the Department of Applied Economics at the University of Minnesota
My summary:
  • initial teacher training needs to improve (only 50% satisfaction)
  • increased motivation and learning (strong anecdotal evidence but details lacking)
  • xo could be used more to distribute books
  • higher workload for teachers, will they maintain this in the long haul?
  • teacher - student relationship have become more interactive and challenging, breakdown of traditional lecture mode
  • nuts and bolts issues like jumpy cursor and chargers at home are very important
(summary updates on 30th September, 1st October)

Extracts only follow: (see more detailed version here )
The Nepal government’s Department of Education (DoE) and the Open Learning Exchange Nepal (OLE Nepal) had selected Bishwamitra Ganesh Secondary School and Bashuki Lower Secondary Schools, both in Lalitpur district of Nepal, as test schools for the One Laptop per Child (OLPC) initiative in Nepal. The laptops were distributed to all 135 students in grade 2 and 6 in those two schools on April 25, 2008. The students were also allowed to take laptops home. However, charging of the laptops could only be done in school...

When the teachers were asked whether the complete training was sufficient for enabling them to properly integrate laptop in the regular classroom instruction process, 50 % of the teachers’ response was positive. This response underscores the need to have refresher training on a regular basis as most of the teachers are using computer for the first time ...

The (teachers) are also of the opinion that laptop based instruction has made it easier to give students more practice exercises. In addition, they also feel that the use of laptop based instruction has made the classes more interactive. All the teachers are unanimous in saying that the use of laptop based instruction has increased the students’ interest in their studies...

When the students were asked how learning has been affected with the introduction of laptops in their classrooms, more than 95% of grade 6 students find learning using laptops easier ... As to why it is easier, the most common response was that you can do the exercise or activities as many times as you want. The second most common one was that these activities were very enjoyable to learn from. The students also appreciated the fact that you could do these activities at ones own pace ...

Some teachers feel that the introduction of laptop has made managing the classes more difficult. Many teachers feel that the noise level has substantially increased ...

When teachers were asked “Compared to the effort you had to put in the teaching learning process before receiving the laptops, how much effort do you put in now?”, the overwhelming majority of the teachers feel that they put in more effort now...

Almost all teachers (16 out of 17) find the laptop and its layout easy to use. They think it is very intuitive and also feel that the students should not have much difficulty. Most of the teachers say it takes about 1.5 hours to fully recharge the computer and that the charge lasts for about 3 hours when the computer is in use.

We had also asked the teachers, students and their family members whether they had any problem with different aspects of computer use. The biggest problem more than 50 % of the respondents mentioned was the jumpy cursor. The dust, the humid climate and the student’s sweaty hands as a result of running around might be contributing to the situation. The problem seems to be slightly more acute in Bashuki.

More than one-third of the teachers thought the sound quality needs to be improved. There either is some problem with the sound quality or that some teachers might have difficulty adjusting the sound. Since earphones are not available, difficulties arise for students and teachers when using sound related activities. They largely ask students to listen to the sound from the teacher’s laptop while teaching...


I think OLE Nepal should try to upload all the books that are in the website to student laptops sooner rather than later ... Needless to say the parents and teachers are really looking forward to using the e-library.

Most teachers in both the test schools feel that their workload has increased significantly. This is a serious concern. If this trend continues, it is likely that they will revert, to a large extent, to traditional way of teacher and ignore the materials in the laptop once the initial enthusiasm of laptop fades away ...

I strongly feel that OLE Nepal should take steps in allowing students to take chargers home so that the laptop can be used longer and that other family members or community members can also benefit ...

I think the OLE-Nepal should go ahead with the plans about providing 2 chargers per student with laptops, so the students can take one charger home and the other one can be permanently kept at School ...

Sugar Labs


This is a comment I posted to the Its an Education Project (IAEP) list (September archive) in response to some members of Sugar Labs being sad about the first Windows XP OLPC pilot.

As a teacher in an industrialised country I'd see Sugar combined with low cost laptops as a vehicle for:
  • immersion - computers are always available not limited exposure in labs - this makes an incredible difference to learning with computers, as Papert and others have argued
  • wide variety and growing of educational software packages (10,000 visits per day to Activities page from Uruguay)
  • constructionist software such as etoys, scratch, turtle art, drgeo etc.
  • python is a great first language, after the visual programming approaches have been tried
  • collaborative aspect is cutting edge, offers new ways of doing things (but not yet working out of the box, unfortunately)
  • linux experience - in the last year or so I am coming across a few students who have taught themselves linux at home - this is a new and slowly growing trend
  • FOSS philosophy of collaborative development fits readily with what good teachers do (cf. hiding your expertise in order to maximise your profit)
What other group, apart from Sugar Labs, offers this potential? Sugar Labs also offers this list as a discussion forum about these issues. Who else provides this?

These things are not obvious to most teachers (for various reasons) but at least some of these things are obvious to a small but growing minority. If Sugar works well out of the box I think there would be small but significant and growing uptake.

Another view (less optimistic) is to look at the history of computing since the 1960s and to realise that most of the important discoveries were made then and since commercial interests got a hold on it the true potential has been largely lost or very much obscured. eg. late binding provides a far superior environment to teach about variables but the dominant systems don't offer that option.

More detail about this vision: http://learningevolves.wikispaces.com/alanKay+talk

MS has a long way to fall but strategically they have peaked are in decline. No need to be too alarmed by the thrashing around of a smelly dinosaur in a tarpit. Other commercial companies, such as Google, will eventually take their place. How does that sit with the Sugar Labs vision? Not sure.

I'd see the issue as a practical one of getting the software to work properly. In terms of vision, strategy and future potential we hold the good cards.

Dr Geo II




This program is customised geometry built from Squeak (formerly Smalltalk). I'm finding that it's great fun to play with. It's available on Linux, Windows or Mac as well as the OLPC. Hilaire Fernandes, the developer, has created over 60 short screencasts, in ogg format, which provides a great way to learn the program.

Above are some screenshots from an exercise I learnt from viewing the
305-rotation-geometric-angle-degree screencast. Create an angle and then dynamically vary the angle - nice! Rotate a polygon around a point and then vary the angle of rotation. This one is a lot of fun!

Sugar evaluation wiki

I have created a wiki, http://xo-whs.wikispaces.com/, where some of the year 10 students at my school are evaluating Sugar activities. I'm interested in feedback: billkerr (at) gmail (dot) com, if you don't want to leave a comment here.

I'm using it to record my own exploration of the activities. At the moment we are looking at Turtle Art and Dr Geo II. Learning a lot and it's interesting. I'm very happy that I've finally worked out a way to play with the Sugar activities in a collaborative context.

Working with Sugar provides a great context for new learning. Many of us have been trapped against our wishes in MS Windows dominated school environments for years. Given that teachers are always very busy there has been little incentive to learn linux, for example, when it is not used in your work environment. I remember I tried years ago but gave up due to workload pressure. Two of my year 10 students know more linux terminal commands than I do so I'm now under pressure to keep up with them. It's great!

One of my year 10 students has built a jabber server, which we can use locally to enable the collaborative features of Sugar.

Due to a bug in the software the collaboration features have not been working so far (without the jabber server) on our particular network, although it is reported to "just work" on Ubuntu networks. With Joel's help this has been reported to the IAEP list and hopefully will be fixed in the near future

Sugar labs is the main home of sugar and seems to be powering along at the moment.
