La Dolce Vita: chapter 9, in which our hero thinks more carefully about our educational mission.
I just spent my weekend reading an exceptional book: Disrupting Class by Clayton Christensen, Michael Horn and Curtis Johnson. Anyone involved in OLPC or Sugar should take the time to read this book.

To summarize, as briefly as possible, the key arguments that I took away from it:

1. It's impossible to attack the education beast head-on. You can't go to the local school board and say "use computers the way I say please, thanks," because that approach never, ever works. Disruptive innovations are seldom developed to replace entrenched competitors; they first address underserved markets, where the status quo is essentially nothing. They prove themselves in this alternative market, grow over time, and ultimately they reach a tipping point at which they deliver functionality that is "good enough", ultimately pushing the incumbent aside. History is full of these examples: the transistor over the vacuum tube, the personal computer over the mini-computer, and so on.

2. There are plenty of underserved markets in American education. With the push towards raising standardized test scores -- arguably at the expense of actual learning -- these underserved market opportunities will increase; as schools are forced to spend more of their budgets on increasing basic scores in basic competencies, many of the "electives" will be pushed aside, and kids will have fewer options. Homeschoolers also represent a vast and growing untapped market.

3. Computer-based learning has the potential to fill these underserved market niches. Johnny wants to learn Arabic to help prepare for his future in the diplomatic corps, but he lives in the middle of Nebraska and there's no Arabic instructor for 500 miles? This is a dream scenario for computer-based learning.

4. Classroom-based teaching is, by its very nature, necessarily monolithic. Teachers can't afford to cater to individual students; textbook authors must write to an audience of hundreds of thousands to make writing a text financially worthwhile; school is broken into twelve grades, that a kid either passes or fails; predictable inputs and outputs; the whole system is built to run schools as though they were factories.

Computer-based learning, on the other hand, has the opportunity to be modular. Subjects could be broken up into small modules, each with its own assessment capabilities; therefore, student mastery of one module could be assured before the student would be allowed to move on to the next. Different modules could be constructed differently to accommodate different learning styles (visual, textual, auditory, etc.), so long as an equivalent assessment of skills mastery could be made. Online tutors could be made available to help with particular subjects, and these tutors could potentially scale much more effectively than teachers.

This is a poor and limited synopsis of a brilliant book. Go read it. It's thoughtful, groundbreaking stuff, and it has a lot of implications for the development of Sugar and other educational platforms. The most interesting implication, for me: perhaps we can stop assuming that we're developing Sugar only for kids in the developing world, and work instead on making Sugar valuable in our own communities.

Imagine, if you will, a Sugar educational wiki that has the following content:

+-------------------------------------------------------------------+
| 4th grade mathematics modules for Sugar!                          |
+---------------------------------+---------------------------------+
| Long division                   |   division-patrol.xo            |
|                                 |   divide-and-conquer.xo         |
|                                 |   divider-man.xo                |
|                                 |   mongo-teaches-division.xo     |
+---------------------------------+---------------------------------+
| Fractions                       |   fraction-patrol.xo            |
|                                 |   mongo-teaches-fractions.xo    |
|                                 |   denominator-dominator.xo      |
+---------------------------------+---------------------------------+
| Negative Numbers                |   mongos-number-line.xo         |
|                                 |   two-wrongs-make-a-right.xo    |
+---------------------------------+---------------------------------+


Now imagine that each of these activities has (a) a testing mechanism that allows demonstration of mastery; (b) a mechanism to record that data over time, for use by a teacher/parent charged with oversight of the child's progress (like, say, the Sugar Journal); and (c) a stamp of approval, provided by some lightweight/sensible approval process that allows teachers/parents to say "yes, this activity teaches the subject, if not perfectly, at least well enough."

Now imagine further that this wiki has the structure for a child's entire K-5 curriculum, across all subjects, with multiple activities to choose for each lesson.

Now imagine further that there exists a critical mass of these activities, written simply enough and documented well enough that a parent/teacher of reasonable intelligence and motivation could examine these activities, modify them to suit, or perhaps even create their own.

This is the kind of promise that Sugar holds, and we need to do a better job of articulating this promise, and figuring out the critical path that allows us to deliver on this promise.

I had a discussion with someone at FUDCon -- maybe it was David Farning, maybe someone else -- in which we discussed homeschoolers as a market to target with initial Sugar releases. That seems like a better idea every day to me.

Sugar folks, again: go read the book, please.

Sounds like he's expanding a little on one of themes he touched on briefly in an earlier book. Unfortunately, he seems to write the same thing over and over so I can't bring myself to read another full Christensen book :)

Obviously the message is the same, but the context is key, and he does a good job of differentiating between business and education, which was the useful insight for me.

I think, if I recall the van ride back correctly, that the person who talked about homeschoolers as a market was Kenny Parnell - and something I dismissed out of hand for OLPC because G1G1 is over. Though we did talk about Fedora running Sugar on a regular desktop as well in that environment.

In all fairness to NN, that's precisely the reason why he was focusing on the developing world -- the initial deployments were intended to be classic underserved markets without a clearly entrenched model.

I think what he found is that even underserved markets have their unique entrenchments to overcome, and in this work, he has been moderately successful, considering. Although clearly not as successful as we'd like. :)

I would respectfully disagree on awareness of entrenched models. With a very short time spent in the developing world, or time spent talking with its leaders, you can quickly ascertain that the educational bureaucracies are some of the clearest entrenched and yet underfunded markets anywhere.

And with only two real national deployments (Uruguay & Peru) neither in Negroponte's original 5 (Argentina, Brazil, Libya, Nigeria, Thailand), I would suggest "limited" vs. "moderate" success.

Now I would say that he did charge the bastion of educational inertia better than anyone else in a long time. That in itself is an accomplishment.

Hello,

I'm a school district administrator, and we actually use a wiki format for our entire official K-12 curriculum It is open to the world, and is up to 11,000 student, teacher and visitor created pages, more or less, on any given day.

Feel free to contribute or edit:

BSSD Open Content Curriculum
http://wiki.bssd.org/

We started the project with same approach to curriculum that Open Source software is based on: Given enough eyeballs, all bugs are shallow. (Eric Raymond, CATB essay)

In addition, we are a standards-based district (continuous progress assessment is implied by your post), and designed our own Open Source student information system to track progress through our curriculum for students, schools and parents. This is our 2nd year of using the system, called DART, and a new release is due in a next couple of weeks.

Finally, I agree with your modularity approach to curriculum. Rice has it right, in many ways. Open Content modules that can be linked together to solve teacher and individual needs are the way things are going to go.

Keep up the blog here. I've subscribed ;-)

Regards,

John Concilus

Wow, John. Thanks for the links. Looks like BSSD is a perfect example of the need to innovate to solve this class of problems. Pardon me now while I scour your wiki for ideas. ;)

You say: "Classroom-based teaching is, by its very nature, necessarily monolithic. Teachers can't afford to cater to individual student."

This is not true. While there are obviously limits, one way teachers are measured is by their success at differentiating instruction for the students in their class. I have watched how this is done -- one common approach is "centers", where multiple activities are conducted simultaneously in the classroom, allowing the teacher to work with individuals in one "center" while other students work in small groups on various activities in pursuit of, say, writing skills or measuring/comparison/estimation in math.

I find the implication among many OLPC and sugar developers that all teachers are incompetent and haven't thought of the blindingly obvious ideas like individualizing instruction, working collaboratively, and so forth to be very off-putting. How many of you have spent a week sitting quietly in a classroom watching what a good teacher does? Not surprisingly, the examples that you come up with in this post are all addressing calculation drill and practice. I am a software engineer too, but I don't assume that people who can't code should shut up (David Farning's latest contribution to the "It's an Education Project" list -- pretty ironic venue.)

I think you are misunderstanding David post. Often on the list we have conversations which are not productive. Both talk and action are important, but talk is easier and hence often tends to be predominant (it's first of all a critique to myself!). David is correct that as a community we need to get better at *making* things and we need to highly value people that does. There are many ways to produce wonderful things for the project, working code being an example.

Anonymous,

I don't know where you've read from any of my posts that I think "all teachers are incompetent," because I am certainly well aware that teachers have been trying all kinds of ideas for years. I've been to NECC and talked to dozens of teachers, and from those teachers I've gained tremendous insights. It's certainly not teachers that are at fault -- it's an educational system that makes innovations wickedly difficult to advance. This is where Clay Christensen's book is so useful as a tool.

And I have been fortunate enough to watch many *good* teachers, and have learned much from watching them. But the sad truth, whether you face it or not, is that not all teachers are created equal, not all classrooms are created equal, and not all students are created equal -- and the way that we are choosing to solve this problem is not to privilege the good and innovative teachers, but to bring schools down to a lowest common denominator through NCLB.

I'm not saying that the computer-based approach solves every problem, either. But now I feel like I've got a much better handle on where computer-based learning *can* be useful, and where Sugar activity developers can be focusing their time usefully.

hi greg,

Take fractions for an example. The main reason fractions are poorly understood is that they are often poorly taught - ie. the methods of teaching the underlying structures of fractions are not widely known by teachers. So, how will we get over the problem of those methods being also not well known to software developers?

The missing step in all of this is improving our knowledge of the basic structures of (eg) fractions and improving our knowledge of how to get that across to kids. Some of this work has been done (eg. Papert / Harel, Nunes / Bryant) but what has not yet been done is writing software that can teach better than a good teacher

There is a bit of learning to do before fraction-patrol.xo and co see the light of day and that is not just developers work

Clayton M. Christensen has written some interesting stuff about disruptive technology in the marketplace. But success in the marketplace is a different beast from success in learning.

I admit, it's a non-trivial problem. But it seems to me that the place to start is to actually articulate the useful work that software engineers should be focusing on. If you look at the activities that have been written to date, it's unclear what pedagogical value many of them have.

And you're absolutely correct: we are not writing software that can teach better than a good teacher. But remember: we are not trying to create software that is "better than a good teacher". We are trying to create software that is "better than no teacher", that is useful to the underserved, and that may be improved over time.

Sugar for the developing world?

"The most interesting implication, for me: perhaps we can stop assuming that we're developing Sugar only for kids in the developing world, and work instead on making Sugar valuable in our own communities."

I have heard this before and I guess it's part of the OLPC influence that we need to get rid of.

I don't really think that Sugar is being developed with the special needs of the developing world in mind. We are just creating an UI focused on learning, with some special provisions for young kids.

And I certainly fail to see which changes we could make so it suits better the developing world that aren't equally beneficial for the developed one.

Learning speed and ability is pretty constant across all humans, and I think the wider use of Sugar to enhance that should not be restricted to one type of deployment or even one hardware platform.

Of course you're right, Tomeu. Inside of Sugar Labs, we understand that we're focused on all kids. But the outside world does not yet understand that, and we need to change those perceptions. That was my point.

Schools are designed as factories.

4. Classroom-based teaching is, by its very nature, necessarily monolithic. Teachers can't afford to cater to individual students; textbook authors must write to an audience of hundreds of thousands to make writing a text financially worthwhile; school is broken into twelve grades, that a kid either passes or fails; predictable inputs and outputs; the whole system is built to run schools as though they were factories.

--------------------------------------------------

The way schools are built is built around the ideas of factories from the early 20th century. Schools in the early 20th century were even more of a grab-bag than they are today. Going to school was not mandatory in many regions and was considered a luxury for many families. As this was causing economic problems, schooling became mandatory and higher grade requirements were added in areas.

The big problem was that money as always was not significantly increased and every school seemed to have its own methodology for getting someone an 8th grade diploma. At some point the same efficiency experts who had mapped out how you could have 4 bricklayers do the work of 12 in the same amount of time.. were brought in to improve schooling. Things were standardized, things were broken into small definable units, testing was brought in, etc etc. Just like factories, you get more 'output' for lower cost if you build bigger facilities and so larger schools were built etc etc.

The problems with the factory viewpoint was that it didn't solve enough problems no matter how many more standardized tests/teaching you give it. Human beings are not very good widgits. You can't just send a kid back to the smelter if it doesn't fit into the cog. You can't build a better kid if 18 hours of its day is spent in a life that is actively working against the 6 you can educate it. And they are very slow to test hypothesis against.. as kids, parents, and society in general do not have the patience of 12-18 years to see if the method works better than a control method.

Which may explain why modern schools instead of being built on the same plans as a large factory are built using the same plans as a prison/penitentiary.

Some great ideas. However, let me suggest that Sugar activities also need to develop in another direction.

There are hundreds of millions of children in the developing world who don't go to school at all because there are no schools or the teachers don't show up. The only conceivable solution to this unserved market is self-instructional software in basic skills like reading and mathematics. It wouldn't be as good as classroom instruction, but it would be far better than nothing at all.

Sugar is perfect for this sort of software. And when XO-2 comes out and gets below $100, then a lot of developing world families could buy their own computers, perhaps to share among several families.

I've been a long-time fan of Clayton Christensen's theories as a useful framework for discussing all sorts of industries and markets. I don't think "Disrupting Class" is his best book, for various reasons, but I still think it's definitely thought provoking and worth reading. For anyone interested, sometime ago I posted about this in the context of Mozilla and education (http://blog.hecker.org/2008/07/25/mozilla-and-the-future-of-education-part-1/). FWIW I think the biggest difficulty will be getting to the point where we have a robust "facilitated user network" (as Christensen calls it) that's producing useful and effective stuff that promotes real learning. Right now we can see pieces of what will be needed (online instruction technologies, open educational resources, etc.) but the whole picture isn't there yet.
