Christopher Alexander’s “A Pattern Language”

A Pattern Language
A Pattern Language

I have just finished reading Christopher Alexander‘s A Pattern Language: Towns – Buildings – Construction, one of the most wonderful books I have read in years.

The scope of the book is incredible. It sets out, in plain terms, to empower people to design, build and shape their own surroundings. It does this by creating a “pattern language”, a kind of generative grammar with 253 patterns that can be used to make things. The patterns move from big town scale patterns (e.g. The Distribution of Towns, Magic of the City, Web of Shopping, Nine per Cent Parking), via medium building scale patterns (e.g. Wings of Light, Intimacy Gradient, Staircase as a Stage) to small  construction scale patterns (e.g. Structure follows Social Spaces, Low Sill, Filtered Light, Different Chairs).

Each pattern is described in a similar way: there is a picture showing an archetypal example of the pattern, then a paragraph describing the context of the pattern (in which larger patterns does this pattern fit), next in bold a headline giving the essence of the problem, then a research based exploration of the problem, next in bold the solution stated as an instruction, then a diagram as a visual way of describing the solution and finally a paragraph describing which smaller patterns can help this pattern. Each pattern also comes with a label signifying how sure the authors are that this truly is an universal pattern.

The breadth of topics in the book is baffling (it took the authors about seven years to research and write it). Let me just give you some random quotes to show you what I mean (doing the book a gross injustice by leaving out a lot of context).

On the magic of a cities:

The magic of a great city comes from the enormous specialization of human effort there. Only a city such as New York can support a restaurant where you can eat chocolate-covered ants, or buy three-hundred-year-old books of poems, or find a Caribbean steel band playing with American Folk singers.

On the evils of supermarkets:

It is true that the large supermarkets do have a great variety of foods. But this “variety” is still centrally purchased, centrally warehoused, and still has the staleness of mass merchandise. In addition, there is no human contact left, only rows of shelves and then a harried encounter with the check-out man who takes your money.

On grave sites:

No people who turn their backs on death can be alive. The presence of the dead among the living will be a daily fact in any society which encourages its people to live.

On why buildings should have gradients of intimacy:

When there is a gradient of this kind, people can give each encounter different shades of meaning, by choosing its position on the gradient very carefully. In a building which has its rooms so interlaced that there is no clearly defined gradient of intimacy, it is not possible to choose the spot for any particular encounter so carefully; and it is therefore impossible to give the encounter this dimension of added meaning by the choice of space. This homogeneity of space, where every room has a similar degree of intimacy, rubs out all possible subtlety of social interaction in the building.

On why your windows should have relatively small panes:

[Thomas Markus] points out that small and narrow windows afford different views from different positions in the room, while the view tends to be the same through large windows or horizontal ones. We believe that the same thing, almost exactly, happens within the window frame itself. [..] The view becomes alive because the small panes make it so.

On lighting every room from two sides:

When they have a choice, people will always gravitate to those rooms which have light on two sides, and leave the rooms which are lit only from one side unused and empty.
This pattern, perhaps more than any other single pattern determines the success or failure of a room. The arrangement of daylight in a room, and the presence of windows on two sided, is fundamental. If you build a room with light on one side only, you can be almost certain that you are wasting your money.

On modern impersonal interior design:

Do not be tricked into believing that modern decor must be slick or psychedelic or “natural” or “modern art,” or “plants” or anything else that current taste-makers claim. It is most beautiful when it comes straight from your life – the things you care for, the things that tell your story.

On high buildings (imposing a four story limit):

There is abundant evidence to show that high building make people crazy.
High buildings have no genuine advantages, except in speculative gains for banks and land owners. They are not cheaper, they do not help create open space, they destroy the townscape, they destroy social life, they promote crime, they make life difficult for children, they are expensive to maintain, they wreck the open spaces near them, and they damage light and air and view. But quite apart from all this, which shows that they aren’t very sensible, empirical evidence shows that they can actually damage people’s minds and feelings.

I could go on and on…

Written in 1977 it is clear that this is a very “seventies” book. The belief in what we in The Netherlands would call “De maakbaarheid van de samenleving” (the ability to create/design/mold society) is very high. It was interesting to reflect on where I grew up and how much of that place was designed according to the same kind of thinking and ideals. I could also find many of seventies based educational philosophy of the school I used to work at in the book. The open doors, the integration of inside and outside, there are even some very explicit ideas on education and learning in the book.

Although many of the patterns are probably very universal (they are very human), I do think the book has some strong cultural biases. This doesn’t make it less valuable though.

The book has really made me want to scratch my own creator’s itch. It makes you want to design things. (Apparently Will Wright, the creator of SimCity, wanted to create this game after reading the book).

What I want to create, inspired by this book, is not a town or a house. I want to write a new pattern language. Wouldn’t it be great if we had a generative grammar for technology enhanced education (or using another term, online learning events)? I see that there have been some attempts to do this already (here and here), but I would love to create a much more extensive work that is in the style of Alexander. Is there anybody who would like to help me? Shall I start a wiki?

If you want more information about the book, then go to its website or read hyperlinked summaries of all patterns.

ReWork Rehashed

Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. For this post we agreed to write about the 37signals book Rework. Each of us will write about the three things in the book that we already do, about three things we will do from now on going forward and about three things that we wish our employers would do from now on. You can read Arjen’s post with the same title here.

Rework
Rework

Jason Fried and David Heinemeier Hansson of 37signals and Ruby on Rails fame have just written a new book titled: Rework (you can download a free PDF excerpt). Reading it gave me an ambivalent feeling: these authors are obviously very good in what they do and they have managed to build a successful business monetizing different parts of their talents, but the book feels like a monetization effort too and the number of words per Euro are very low. Arjen Vrielink has written a quite damning review on Goodreads.

Nonetheless it has some interesting lessons to offer. It has about 100 pieces of advice for people starting their own business or working in a business. Some of the advice I already practice, some advice I will try to practice from now on and I wish that the company I work for would practice some of the advice going forward.

Three chapters about things I already do:

Build an audience (page 170)
Traditional PR and marketing is about going out and trying to reach people. The ubiquity of the Internet allows you to let people come to you instead of the other way around.

When you build an audience, you don’t have to buy people’s attention – they give it to you. This is huge advantage.
So build an audience. Speak, write, blog, tweet, make videos – whatever. Share information that’s valuable and you’ll slowly but surely build a loyal audience. Then when you need to get the word out, the right people will already be listening.

Emulate chefs (page 176)
In this chapter the authors make a case for sharing everything you know, something which is anathema in the business world. They use famous chefs as an analogy. The best chefs share their most valuable recipes in their cookbooks. Why? Because they know that their business as a whole cannot be copied. What better way to show you are an excellent cook, then by sharing your recipes?
I am convinced that there are only benefits to sharing everything I know about educational technology and innovation with anybody who is willing to listen. Doing this is the only way to take part in the incredibly valuable discourse on this topic and taking as much out of it as possible.

Forget about formal education (page 215)
Companies still over-value formal education from. I have personally decided to attend as little formal education as possible from here on further. The key qualities that somebody needs to have are curiosity and the ability to learn. If you combine these two, then there is a whole world out there from which you educate yourself. You don’t have to go and sit in a stuffy classroom and listen to some academic lecturing. Don’t get me wrong: academics are hugely valuable. It is just that you don’t have to join a university to engage with them.

Three chapters about things I will try to do from now on:

Embrace constraints (page 67)
This chapter starts as follows:

“I don’t have enough time/money/people/experience.” Stop whining. Less is a good thing. Constraints are advantages in disguise. Limited resources force you to make do with what you’ve got. There’s no room for waste. And that forces you to be creative.

This is a principle that I am already highly aware of (it is actually embedded in every introduction to any Parallax post on this blog). It is not something I am naturally good in though. I love gadgets and these things often create a lot of extra affordances and thus complexity. I need to tone this down to allow a better focus on things that really matter. First step: “downgrade” my current Ubuntu 10.04 setup which allows me a lot of flexibility (and gives me wobbly windows, that’s not me by the way) to the Ubuntu Netbook edition.

Focus on what won’t change (page 85)
This is probably advice that anybody tasked with working on innovation should heed to. Naturally we like to be focussed on the next big thing. The danger is that you will focus on fashion instead of on substance.

The core of your business should be built around things that won’t change. Things that people are going to want today and ten years from now. Those are the things you should invest.

I will try and use this advice while thinking about the next iteration of our learning landscape. Which aspects are lasting needs and wishes and which are just fads?

Interruption is the enemy of productivity (page 104)
I work in an office with about 10 other colleagues (if everybody is in). During a working day I receive about 50 emails in my work Outlook inbox and have multiple instant messaging conversations. This means that I barely have a couple of minutes without any interruptions. I have to admit that I am probably the cause of many interruptions too, as I constantly share the things I find fascinating or funny with my co-workers.
This is definitely not beneficial for my ability to do work on things that require a bit more concentration and need me to be focussed. It takes a lot of time to write anything which is more than a page of two for example. Usually I can only do it if I work from home and I turn Outlook off. From now on I will try to block a couple of hours every week during which I will sit by myself, turn off my phones, IM and email, refuse to look at Google Reader and just work.
It is as the authors say:

Your day in under siege by interruptions. It’s on you to fight back.

Three chapters about things I wish my employer would do going forward:

Meetings are toxic (page 108, available in the free excerpt)
This one is pretty obvious, but we still have a complete meeting culture. Everybody knows that meetings are not very effective at what their intent is to do and still we have way to many. Some of the reasons the authors give for why meetings are this bad are:

  • They usually convey an abysmally small amount of information per minute
  • They require thorough preparation that most people don’t have time for.
  • They often include at least one moron who inevitably gets his turn to waste everyone’s time with nonsense
  • Meetings procreate. One meeting leads to another meeting leads to another…

If you still need to have a meeting I like their simple rules:

  • Set a timer. When it rings, meeting’s over. Period.
  • Invite as few people as possible.
  • Always have a clear agenda.
  • Begin with a specific problem.
  • Meet at the site of the problem instead of a conference room. Point to real things and suggest real changes.
  • End with a solution and make someone responsible for implementing it.

I think we are especially guilty of inviting too many people to meetings and I would love to meet at the site of a problem instead of a conference room, but am not sure how this is done with IT related issues.

Don’t write it down (page 164)
We spend an inordinate amount of time capturing everything everybody says, needs and wants. We have hundreds of Excel files containing lists of requirements, feature/enhancements requests, issues, etc. We probably spend more time managing these spreadsheets than working on the issues that these spreadsheets are an abstraction of.

There’s no need for a spreadsheet, database, or filing system. The requests that really matter are the ones you’ll hear over and over. After a while, you won’t be able to forget them. Your customers will be your memory. They’ll keep reminding you. They’ll show you which things you truly need to worry about.

Don’t scar on the first cut (page 260)

The second something goes wrong, the natural tendency is to create a policy. “Someone’s wearing shorts!? We need a dress code!” No, you don’t. You just need to tell John not to wear shorts again.

This is how bureaucracies are born according to the authors. They consider policies “organizational scar tissue”. I work for a company that, like most other I am sure, is very scarred. Let’s all stop scarring it more!

I have to admit that a list of three was severely limiting when it came to wishes for my employer. I would have like to have the opportunity to add: Ignore the real world (page 13), Illusions of agreement (page 97), Hire managers of one (page 220) and They’re not thirteen (page 255).

Summary of and Reflections on “Learning in 3D”, Chapter 1

The first chapter of Learning in 3D titled “Here Comes the Immersive Internet” consists of three parts. The first part gives an overview of the three “Webvolution Waves”, the second part focuses on four convergence points that all lead to a next-generation Immersive Internet architecture and the chapter closes with a short analysis of what this might mean for the enterprise.

Three Webvolution Waves
The web browser arrived in 1993 and was used to connect “to” the information that was available on the web. The web grew fast and businesses helping people with getting on the web (Internet Service Providers like AOL) or finding the information on the web (e.g. Yahoo and Google) where the clear winners of the first wave.

In the early noughties companies like Google and Amazon truly started to leverage “the aggregated behaviour of many users to differentiate their [..] offerings”. This insight combined with the increased ability of people to participate in the web by uploading their own content became the core of “Web 2.0“, characterised by the authors as connecting “through“.

Allegedly the next phase of the web will be about connecting “within” and immersive 3D  experiences will be a fundamental part of that. Kapp and O’Driscoll give a couple of examples, mainly from MMORPGs. In games like World of Warcraft people come together in a (semi-) three-dimensional worlds and collaborate as teams to battle other team. There is real economic value in these games as the practice of gold farming clearly shows.

The description of this third phase obviously has much less clarity than the first two phases: we are now in this “webvolution” and we are not sure which of these points are the most salient aspects. I don’t think that “immersiveness” is the only candidate to be at the heart of the next generation of web technology. It could still be that the semantic web will have more impact on social practice. Or alternatively it could the social graph which will be the all pervasive aspect of the new web. In that latter case Facebook seems to be in prime position to be the next Google with their recently announced Graph API. I am sure these trends reinforce each other, but I am not sure that 3-dimensionality will be as important as this book seems to think it will be.

Four Convergence Points
The authors think there are four current technologies that are integrating with each other, creating four convergence points in the process. All these points converge to the immersive Internet. I don’t want to steal their diagram (you can find it on page 18 of the book), so I’ll describe it here.

  • 2D synchronous learning and knowledge sharing spaces are combining to create immediate networked virtual spaces.
  • Knowledge sharing spaces and web 2.0 technologies are integrating into intuitive dynamic knowledge discovery.
  • Web 2.0 technologies and virtual world technologies are coming together in interactive 3D social networking.
  • Virtual world technologies and 2D synchronous learning together can create immersive 3D learning experiences.

I really like this model as it provides four clear spaces in which you could look at technology. The problem for me is that in my job I do indeed see immediate networked virtual space and am starting to see intuitive dynamic knowledge discovery, but I do not see the two 3D convergence points yet. This could be my lack of knowledge and experience of what is out there, in which case I would gladly see some examples and demonstrations!

What does this mean for business?
The web has had a profound impact on the way we do business and organise ourselves. I want  to address the points that I thought most interesting by quoting three passages from the book. The first quote is about information abundance and the subversion of hierarchy by networks:

As the Internet continues to pervade society, the scarcity paradigm that undergirds most modern economic theory is being challenged. Unlike currency, information is non-appropriable, which essentially means that it can be shared without being given away. Today, information no longer moves in one direction, from the top to the bottom or from teacher to student. Instead, it has a social life all its own.

The second quote is about how the web allows people to come together without needing formal organisations to do it:

As communication costs have decreased and the quality of web-based interactivity has increased, communities of co-creators no longer need to rely on a formal organization to become organized. Rather than employing an enterprise infrastructure to plan ahead of time, they leverage the pervasive and immersive affordances of the web to coordinate their activities in real time.

The above is one of the most important points (and actually the subtitle) of Clay Shirky’s wonderful Here Comes Everybody and I think this reading group is an example of how this can work.

And finally a quote about how companies have to innovate faster and how this affects the role of the learning function in the enterprise:

For change to occur it is a precondition that learning take place. [..] In the case of the centralize hierarchies, [organizations] must unlearn all that brought it success in the pre-webvolution era and quickly learn how to leverage the Immersive Internet to reconfigure its resources and capabilities to achieve sustainable competitive advantage in a world gone web. […] The perennial challenge of the learning function within the enterprise is to ensure that human capital investment yields a workforce capable of innovating faster than the competition and work processes that allow the organization to adapt to changes with minimal disruption. This suggests that the learning function should become increasingly strategic to the enterprise.

The last sentence is the step-up to the rest of the book. I am looking forward to it!

Questions for discussion
Please participate in these two polls:

[polldaddy poll=3107820]

[polldaddy poll=3107841]

In the teleconference I would like to discuss the following questions:

  • In what way has your company or organisation changed because of the webvolution? How has this affected the learning function?
  • What are your thoughts about the convergence to an immersive web? Do you have examples of how 2D synchronous learning and web 2.0 combine with 3D virtual worlds?
  • What will change when we make the shift from a scarcity paradigm to an abundance paradigm for information.

We will discuss these questions in our weekly teleconference on Monday April 26th at 15:30 CET. Please contact me if you want to call in and don’t have the dial in details.

Learning in 3D: Please Join My Reading Group

Learning in 3D
Learning in 3D

My company is piloting serious gaming in the learning domain using an immersive 3D environment based on the Unreal engine. We are on the cusp of developing a game around hazard recognition scenarios that are based on real life experiences. Because of this I am reading up on serious gaming and game design in general. After finishing the brilliant The Art of Game Design by Jesse Schell (more about that book in a later post), I now want to tackle Learning in 3D, Adding a New Dimension to Enterprise Learning and Collaboration by Kapp and O’Driscoll.

I have decided to start a reading group which will read the ten chapters of the book in ten weeks (there is a preview of the chapters here). We will use blogs, Twitter, Delicious and a weekly teleconference to communicate around the book.

So how will this work?

Goal
The book provides principles for architecting 3D learning experiences (including a maturity model for immersive technologies) and has lessons on and examples of implementations in enterprise situations. The goal of the reading group is to actively internalise these lessons and see how they can be applied in our own organisation(s).

Participants
As I want this reading group to impact the learning function in my own organisation I intend for about 50% of the participants to work for Shell and for the rest to come from my network outside of Shell. The minimum number of participants is 5 (doing two chapters each) and the maximum is 40 (four people per chapter and incidentally the limit of our teleconferencing solution). Everybody will have to acquire their own copy of the book. (I used the Book Depository to buy this book, as they have free shipping, note that I will earn a small referral fee if you click this link and then buy the book).

Process
The reading group will have a weekly rhythm with a particular chapter of the book as the focus of attention. The following activities will happen every week:

  • One or more people will be assigned to write a summary of the chapter on their blog (if they don’t have a blog, they email me the summary and I will publish it on this blog). The summary ends with at least one multiple choice poll and a discussion question/proposition, both used as input for the teleconference.
  • All reading group participants will be tweeting questions and comments about the book (using a designated hashtag, see below).
  • Each participant will try to add at least one interesting link to Delicious (again with a hashtag) that relates to the chapter of that week.
  • At the end of the week (actually on a Monday), there is a teleconference where the summarisers for that week lead a discussion about the chapter, using the poll and the discussion question/proposition as input.

Hashtag and aggregation
All Delicious URLs, blogposts and Tweets should be tagged with the #Lin3DRG hash tag (stands for: Learning in 3D Reading Group). This will allow me to try some smart ways of aggregating and displaying the data using things like Yahoo Pipes or Downes’ gRSShopper. I promise to write another post on my aggregation strategies.

When and where?
It is going to be a virtual affair, co-creating on the web. We will start reading on April 19th, will have our first weekly 30 minute teleconference on Monday April 26th at 15:30 Amsterdam time and will close out on June 28th (so we will have 10 telcons on ten consecutive Mondays at the same time, it is not a problem if you miss one, we will record them).

Do  you want to join the reading group? Then please fill out a comment with your name, email address, blog URL (not required) and any comments or questions you might have at the bottom of this post. I will get back to you with your assigned chapter(s), some more information on the process and the call in details for the teleconference. You can put your name down until Monday April 19th.

I am really looking forward to it!

Book Review: Moodle 1.9 Teaching Techniques

Moodle 1.9 Teaching Techniques
Moodle 1.9 Teaching Techniques

Just over a year ago I reviewed four Moodle books published by Packt Publishing. Since then, a lot of new Moodle titles have been added to their catalogue. Richard Dias, Marketing Research Executive at Packt, has kindly sent me a copy of one of these new titles for review: Moodle 1.9 Teaching Techniques by William Rice and Susan Smith Nash, first published in January 2010.

William Rice has already published a couple of books with Packt. This book seems to be an effort by Susan Smith Nash to  build on an earlier version of the book by Rice. She adds some learning theory and instructional design essentials to the earlier text.

The fact that this is an update of a much older book, doesn’t work very well. Let me share some examples of where it goes wrong:

  • Chapter 2 used to be called “Forum Solutions”, now it has been retitled to “Instructional Material”. This is weird: Moodle’s core functionality and strongest pedagogical tool is first introduced as a way to clearly display course information and structure. Then on page 25 there is a paragraph titled “Creating a Separate Group for Each Student”. The context from the earlier book (you might want to do this to create private conversations with students) is omitted, making it a confusing set of pages.
  • Chapter 4 has a section that explains how you can exclude quiz grades from a particular quiz in the grade book. The screenshots and explanations are taken from an earlier version of Moodle and do not relate to Moodle 1.9. Moodle 1.9 has a completely different grade book (and has been released since March 2008). It is unforgivable for a book that is published in 2010 to get this wrong. I don’t understand how the reviewer missed this. Hopefully a corrected version will be published as an erratum.
  • The introduction to the book explains that  a basic level of Moodle understanding is assumed for the reader as it wants to focus on learning theory. However it then spends more than 5 (of its 193) pages on explaining what an IP address is and how it can be used to restrict access to a quiz. It gets the Linux part on how to see your IP address wrong (another one for the errata).

The book doesn’t really make optimal use of the new and advanced functionality that Moodle 1.9 has on offer. Two examples:

  • The concept of “groups” is used in the book in some descriptions of course activities (although not enough to call for its own spot in the index), but the concept of “groupings” isn’t mentioned anywhere. If I were to teach a course with Moodle tomorrow, I would definitely use this functionality as it allows you to be much more flexible in your course design.
  • Ever since Moodle 1.7 it has been possible to play with roles and capabilities in Moodle. That functionality is relatively hard to understand and needed some maturation. It is much more usable now in Moodle 1.9. This functionality is only used once in the book (during the discussion on forums) and isn’t explained well enough to my taste.

Does the book have some valuable things to offer? It is not all bad:

  • Some of the introductions to learning concepts are theories are good starting points for further exploration. For example, I liked the reference to Bruner’s “scaffolding” concept and spent some time reading the Wikipedia article on instructional scaffolding.
  • The pages on basic chat etiquette and wiki etiquette are quite useful. They describe rules you can agree on with your students to make the online learning process more pleasurable.
  • The ways of using the choice activity have been slightly expanded compared to the earlier version of the book.
  • The last chapter has a nice example of a capstone project assignment that you could adapt for your own teaching. To use the workshop module as the basis for this project assignment is a bit risky, as I would not recommend anybody to use the workshop module in its current state (Moodle 2.0 should solve that problem).

All in all I would not recommend anybody to get this book. If you have 30 euros to spend on a Moodle book (this book isn’t cheap!) choose one of the ones I recommend here. If you have a basic understanding of Moodle and are looking for generalised teaching techniques for online courses you are much better served by Gilly Salmon‘s work on e-moderation (see E-moderating and E-tivities).

Hopefully I can be more enthusiastic about the next Packt title I get to review…
