Over the past few years my scholarly focus has shifted into areas related to teacher creativity and transdisciplinary learning. I see this as being the next step in my research work. Though I have been thinking quite a bit about this, have applied to to my teaching (particularly my course on Creativity in Teaching and Learning), and there have been occasional blog posts about this as well, it has not had much of an impact on my academic writing. A large part of it has to do with the fact that academic writing (writing for journals and edited books) has, by necessity, a longer time-frame than teaching or blogging. Writing and submitting, taking care of changes suggested by editors and reviewers, and then waiting for the actual publication to emerge, all take time.

To cut a long story short, the first article about this new line of work has finally been published. It is a special issue of the journal Educational Technology devoted to Emerging Technologies and Transformative Learning. This special issue was edited by George Veletsianos and Brendan Calandra (thanks for giving us the opportunity) and was co-authored with Matt Koehler (no surprise there) and Danah Henriksen.

Educational Technology had quite stringent word-limits and length requirements, so the final published article is much shorter than what we had originally submitted. And since I had already felt that the original article was shorter than it needed to be… the final version seems more than a bit truncated. For this reason I am providing links below to both the published piece and a longer unpublished version. If I had to choose, I would read the longer version but that need not be your choice.

Abstract: In this article we examine the need for fostering transformative learning, emphasizing the roles that trans-disciplinary thinking and recent technologies can play in creating the transformative teaching and learning of the 21st century. We introduce the Technological, Pedagogical Content Knowledge (TPACK) framework as a starting point for discussing the special kinds of knowledge, skills, and understanding that teachers require in order to become effective classroom mediators of transformative learning experiences. Within this framework, we propose seven cognitive tools needed for success in the new millennium, and describe examples of how teachers can repurpose digital technologies to use these cognitive tools. We explore the implications for research and practice.

Here is a link to the longer (draft) version.

May years ago I wrote an essay titled On becoming a website. It was about my experience on teaching online and I suggested somewhat facetiously that in order to be a good teacher online I needed to actually “become” the course website! I started the essay by describing the idea of a cyborg:

A cyborg is a cybernetic organism — a hybrid of machine and organism, a creature of social reality as well as a creature of fiction. It has been argued that we are all cyborgs now (Haraway, 1991). Be it a pacemaker installed in our hearts or a pair of contact lenses in our eyes, technologies are now an integral part of our bodies and our consciousness. … Of course these socially (and increasingly biologically) embedded technologies often become transparent and, in some sense, so deeply intertwined with our existence that we don’t even realize they exist (Brooks, 2002).

Now this idea of a cyborg was somewhat of a rhetorical move, to generate interest in the topic I was writing about. So imagine my surprise when I read the following paragraph.

They gave her The Device when she was only 2 years old. It sent signals along the optic nerve that swiftly transported her brain to an alternate universe—a captivating other world. By the time she was 7 she would smuggle it into school and engage it secretly under her desk. By 15 the visions of The Device—a girl entering a ballroom, a man dying on the battlefield—seemed more real than her actual adolescent life. She would sit with it, motionless, oblivious to everything around her, for hours on end. Its addictive grip was so great that she often stayed up half the night, unable to put it down.

When she grew up, The Device dominated her house: no room was free from it, no activity, not even eating or defecating, was carried on without its aid. Even when she made love it was the images of The Device that filled her mind. Psychologists showed that she literally could not disengage from it—if The Device could reach the optic nerve, she would automatically and inescapably be in its grip. Neuroscientists demonstrated that large portions of her brain, parts that had once been devoted to understanding the real world, had been co-opted by The Device.

What a terrible terrible story. How and why did the parents give the device to a 2 year old! Is this kind of brain damage reversible?

So what IS this device? Well turns out it is a book!

Go back and read the passage again, making that switch! How does that feel?

I had written earlier about Douglas Adams’ rules about technology

1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
2. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
3. Anything invented after you’re thirty-five is against the natural order of things.  (p. 95).

It seems to me that this quote, which incidentally is taken from an article in Slate Magazine, reviewing Sherry Turkle’s latest book, captures the manner in which new technologies are often seen to go against “the natural order of things.”

Whether we like it or not, we are all cyborgs now.

I have always been interested in what lies at the intersection of science and art. There are of course many different ways of looking at this. There is the idea of scientific creativity being both similar to and different from artistic creativity. And then there is the idea of artistically representing scientific ideas. I have written about this elsewhere in the context of poetry (both scientific poetry / sci-po or mathematical poetry / math-po). I have also argued that this process of “translation” from one medium to another is a very powerful way of both understanding the issues at hand but could also be an interesting teaching tool. For instance see these sci-po’s written by Sean Nash’s students. As I had said before, echoing Sean, in the context of writing a mathematical proof in verse (click here if you are interested), this act of writing a poem about mathematics forces you to truly and deeply understand the idea before you can start playing with it.

Such artistic representations of science can also be a powerful tool for outreach – to communicate often abstruse and complex ideas to a wider audience. One of the best approaches that has received some attention in the past years is Dance your Ph.D. As the Science Mag website says

The dreaded question. “So, what’s your Ph.D. research about?” You could bore them with an explanation. Or you could dance.

That’s the idea behind “Dance Your Ph.D.” Over the past 3 years, scientists from around the world have teamed up to create dance videos based on their graduate research. This year’s contest, launched in June by Science, received 45 brave submissions.

Today, judges—including scientists, choreographers, and past winners—announced the finalists in four categories: physics, chemistry, biology, and social sciences. Each receives $500.

I just spent a day at MICDS in St. Louis talking with a small but select group of teachers about creativity in teaching, the role of big ideas, the meaning of TPACK, the importance of trans-disciplinary learning (among other things). What a wonderful way of spending the day! This visit was organized by Elizabeth Helfant at MICDS. Apart from the workshop, it was also wonderful to finally meet up with Mr. Nashworld, Sean Nash himself. Sean and I have been blogging buddies for a while now and it was great to finally meet up with him.

As a part of our activities today I had all the participants crate i-Images. I have written about i-Images on this blog before (see here and here).

i-Images are the brainchild of David Wong and you can find his page on i-Images here.

Anyway, here are some of the i-Images created today. I do think they are pretty cool and thought provoking, each in its own way. Click on the images below to see what the workshop participants created. Enjoy.

Three different news-stories/articles came to my notice today all connected by the infamous brood parasite the cuckoo. The first is a part of Olivia Judson’s blog (on the NYTimes) on biology and life (read Cuckoo! Cuckoo! here), the second is is about how scientists have tried to understand what it is that the cuckoo does to trick other birds into caring for the cuckoo’s eggs (read, Scientists Get Bird’s-Eye View of How Cuckoos Fool Their Hosts) and the third is regarding a new way of engineering design and optimization inspired by the Cuckoo! (read about the ‘Cuckoo Search Algorithm‘ here)  .

Olivia Judson makes a very important point about how our perceptual systems prevent us from seeing the world “as is.” For instance, as it turns out what we “see” when we see a cuckoo’s egg is very different from what the bird sees. As one of the articles say:

In the past, this kind of analysis was tackled by humans comparing eggs by eye, but human vision differs hugely from that of a bird. Birds can see ultraviolet light and because they have four types of cone in their eyes, compared with three in humans, they see a greater diversity of colour and pattern.

What this means is that over evolutionary time, cuckoos and the host birds are engaged in an arms-race to develop better and better deception (on the cuckoo’s part) and detection (on the part of the host birds) mechanisms. As a consequence one of the host birds studied:

… lay probably the most diverse range of eggs of any bird in the world, and this is likely to be an outcome of the long co-evolutionary battle with the Cuckoo Finch.

The eggs are analogous to a bank note, in terms of the variety and complexity of markings, perhaps to make them very hard to forge by the parasite.

So the same techniques used by currency designers to reduce forgery (the intricate markings that are the defining characteristics of today’s currency notes) is used by the host birds as well. Of course forgers keep coming up with better techniques to trick us, as do the cuckoo birds… all this of course leading to a runaway race where every innovation by the forgers (read cuckoo birds) has to be matched by the police (read host birds).

Now, it turns out that a couple of engineers have take this a step further, utilizing the idea of this evolutionary war to develop a better search algorithm! So what we have here is an interesting confluence of evolutionary forces and the manner in which scientists have tried to understand how these forces work and leading to the development of new technologies and techniques for solving engineering problems. How very cool is that!

All this is interesting in and of itself, but there is a deeper point about perception being made here that I would like to highlight. Olivia Judson says it much more eloquently than I ever could, so I quote:

Which makes me wonder: what are we missing? Like the birds — like any organism — our sensory system defines the way we perceive and interact with the world, and it is limited in important ways…

And in a more metaphorical way, the sight of the cuckoo chick makes me wonder what we miss by our routine habits of thought. To what extent do our preconceived notions narrow our perception of the planet, and ourselves?

What a great question? What are we not seeing? How do we learn to see?

Followers of this blog (and people who have seen my presentations on creativity) know that this idea of “learning to see,” is in my opinion, the most critical first step towards being creative. I have talked of this in terms of “recognition v.s. perception” and it underlies my arguments for repurposing technology (that I go on and on about, most recently here). I think it is important that we continually ask ourselves this question that Olivia Judson leaves us with:

To what extent do our preconceived notions narrow our perception of the planet, and ourselves?

In other words, what are we not seeing?

I just discovered Peter O. Gray’s blog on Psychology Today, titled Freedom to Learn: The roles of play and curiosity as foundations for learning. This is an awesome blog and really worth reading. Here are two of his posts that I strongly recommend. The first states (over and over again) the fact that “School is prison” and makes a good argument for why that is indeed the case. The next post unpacks that statement somewhat by exploring the idea of compulsory education.

• “Why Don’t Students Like School?” Well, Duhhhh…
• Seven Sins of Our System of Forced Education

For the record, here are a couple of his papers as PDF downloads (I recommend the first, though it may be a bit academic at first glance).

• Play as a Foundation for Hunter-Gatherer Social Existence
• Nature’s Powerful Tutors: The Educative Functions of Free Play and Exploration

And finally here is a video of a presentation he made at the Evolutionary Studies Program at Binghamton University. Read the rest of this entry »

… um… pretty much everything, rendered as a 2100 page-long flipbook.

Sean had this wonderful post on his blog (Is this a sluggish strategy?) about this whole scientific and mathematical poetry that is going around. He links to some excellent sci-po’s written by his students (see Pushing Scientific Thought Into Art) and also provides a nice protocol for those who want to apply it in their own classrooms.

It is amazing to me just how this idea has spread. It has en-livened my life, I can say that much. Anyway, I wanted to say thanks to Sean (and his students) – and what better way to say it than in verse. So here is: For Sean & his students

Jordy Whitmer over at the Birmingham School district forwarded me this link to this really cool video by George Kembel on Awakening Creativity. There is a lot in the video to ponder and discuss but I want to focus on something he said about music learning that really hit home with me. Citing some research on music learning he describes a strong link between speaking a tone language, such as Mandarin, and having perfect pitch. A search on Google led to the following article: Tone Language Translates To Perfect Pitch: Mandarin Speakers More Likely To Acquire Rare Musical Ability. As this article says:

Perfect, or absolute, pitch is the ability to name or produce a musical note of particular pitch without the benefit of a reference note. The visual equivalent is calling a red apple “red.” While most people do this effortlessly, without, for example, having to compare a red to a green apple, perfect pitch is extremely rare in the U.S. and Europe, with an estimated prevalence in the general population of less than one in 10,000.

So think about this for a second. Here is an ability that was once thought to be extremely rare, within the capability of just extremely talented musicians. People born with this talent, as it were. This research, however, shows just how mistaken this view is.

Telegraph article titled: Charles Darwin film ‘too controversial for religious America’

How sad is that!

Imagine controlling machines, typing text or juggling balls using nothing but the power of thought. What sounds like far-fetched science fiction is gradually becoming possible, providing hope for disabled patients — and new gimmicks for the computer gaming industry. Read more in Playing With Your Head: The Dawning Age of Mind-Reading Machines

What implications do these new technologies have for learning and education? I mean even Mattel is getting into the action… As the article says

The new system Mattel is introducing at computer trade shows is called “Mindflex.” According to the company’s fact sheet: “A true mental marathon, Mindflex exercises the brain in an entirely new way as players learn to continuously control their brain activity.”

So, you ask, how does it work? To train the brain, the user puts on a headband with sensors at the temples and a cable connected to something that looks like a mini miniature golf course. Then the user tries to master the first task: balancing a small ball above an air current, causing it to levitate and making it pass through a plastic ring.

At this time these interfaces work only in one direction, from the brain to the computer. But can the reverse, from computer to the brain be far behind? The power being discussed here is truly revolutionary. We have all known that computers are cognitive tools i.e. working with them changes the way we think. However, at some level changes in brain states are mediated via our senses and through movement, a somewhat inefficient process. What these technologies indicate is the future is in a merging of our brains directly with the computer… where the distinction between us and the machine will be increasingly blurred till we won’t be able to tell one from the other. Imagine having access to Google like search engines whenever a question pops up in our heads? How can we tell where the brain ends and the machine begins?

A while ago I had written about how we use language to capture intangible ideas – and the risks associated with not paying attention to these intangibles. I had said (though you can read the complete post A different language):

For instance wine connoisseurs have developed a specialized language (which sadly is quite opaque to me) to explain to each other characteristics of wine. So the words “fruity” and “dry” have specific gustatory connections… What we need to do is develop a language that allow us to somewhat consistently express and represent the intangibles of teaching, somewhat like what Bird does in explaining his music (or wine connoisseurs do when describing wine). The lack of such a language essentially prevents us from recognizing that classrooms are far more than 4 walls, a teacher and a bunch of students… and that aesthetics play a great role in the act of teaching and learning.

Now here is “scientific” proof of what I was saying. In goofing around on the web I came across this article on PubMedCentral titled Six senses in the literature. The bleak sensory landscape of biomedical texts. The authors Raul Rodriguez-Esteban and Andrey Rzhetsky argue that

When we read prose—whether technical or literary—our mind parses sentences to recover their meaning. Yet, the flow of the words themselves can invoke surprising or unexpected sensory responses, even for the writer. Even a very rational and technical text can typically affect the reader on multiple cognitive levels, in addition to its basic task of transmitting the author-intended meaning.

This led them to wonder about the kinds of words used in scientific texts, specifically biomedical texts. Being good scientists, the decided to test this out:

In this study, we therefore analysed the frequencies of use of sensory words and time-related terms in a large collection of biomedical texts, and compared the results with similar analyses of a collection of news articles, a large encyclopaedia, and a body of literary prose and poetry.

And what did they find? No real surprises here:

We found that, unlike literary compositions and newswire articles, biomedical texts are extremely sensory poor, yet rich in overall vocabulary. It is likely that the sensory-deprived writing style that dominates the biomedical literature impedes text comprehension and numbs the reader’s senses and mind.

In conclusion they say:

In short, we believe that scientific prose should be enriched with sensory words, provided that they clarify the meaning rather than obscure it, in much the same way as a good statistical data visualization involves the mapping of abstract data into colours and three-dimensional shapes, to help the reader or viewer discover meaningful patterns.

I think the analogy to visual representation is right on… and I could not agree more with their conclusion.

Just came across this on the Ph.D. design list (a listserv for discussion of PhD studies and related research in Design) from a posting by Charles Burnette. He quotes Donald MacKinnon, author of a large study on creativity in the arts, sciences and professions:

If I were to summarize what is most generally characteristic of the creative [individual] as we have seen him (sic), it is his high level of effective intelligence, his openness to experience, his freedom from petty constraints, and impoverishing inhibitions, his aesthetic sensitivity, his cognitive flexibility, his independence of thought and action, his high level of energy, his unquestioning commitment to creative endeavor, and his unceasing striving for creative solutions to the ever more difficult … problems he constantly sets for himself.

The question to ponder is, how many of these correlates of creativity are amenable to teaching (i.e. can be taught / nurtured) in the classroom or other contexts and how many are completely outside of our control?

Charles Burnett also provides a couple of references to MacKinnon’s work:

MacKinnon D W. (1962). The nature and nurture of creative talent. Amer. Psychol. 17:484-95.

MacKinnon, D. W. (1978). In Search of Human Effectiveness: Identifying and Developing Creativity. Creative Education Foundation.

What does it mean to represent something? Sean Nash (of Nashworld) and I have been having some fun at the expense of periodic representations (my post and his response) and even children’s books.

However, I stumbled upon a way of thinking about DNA that prompted (actually forced) me to write this post. Read the rest of this entry »

Interesting article in Scientific American about how flaws in our biology reveal our evolutionary history. Steven Gould talked about it in his famous essay on The Panda’s Thumb.

This is a wonderful argument for Darwinian evolution since it points not to perfection (which the deniers of evolution can point to as well as example of divine intervention) but rather to imperfection (which is somewhat more difficult to explain by non-evolutionists – why would an all-powerful deity make mistakes). The lesson here is that imperfections point to a contingent historical past. Tracing these imperfections allows us to make inferences about how things came to be. Think of the Qwerty keyboard, to take an example from technological evolution, an artifact from the days of early manual typewriters, that actually required a design that would slowdown people’s typing speed to prevent the keys from getting stuck.

Just came across another page devoted to the same issue, just with more examples.

A quote in a NYTimes article caught my attention

According to sports scientists, the most significant predictor of an athlete’s skill is the time spent in practice. “It’s not just genetics,” says Jean Côté, the director of the School of Kinesiology and Health Studies at Queen’s University in Ontario, Canada, who has extensively studied the development of athletic talent in children. “There’s no magic to it. To become an expert in music or sport, it takes about 10,000 hours.”

10,000 hours! Given 20 hours a week working on some talent, it comes to around 10 hours years. Turns out that is quite exactly the time that Howard Gardner says that it takes someone to become an expert in any domain. Interesting.

Are we becoming cyborgs? William Saletan has a recent article in Slate titled Full Metal Socket about this issue.

If there is an IQ test for everything, why not one for color. This is Howard Gardner multiple intelligences run rampant. Check out the Color IQ test. BTW, my score was 27 (where 0 is a perfect score and 99 is as bad as you can get!). Irrespective of what you think of the test, I must say the interface for collecting the information is quite cool, similar to some of the survey techniques I had discussed in the personal DNA test.

Does it matter whether a brownie is served on a paper plate or on china? Is the Patagonian Toothfish less tasty than the Chilean Bass?

Learning through play has been an important part of my philosophy of teaching (and learning). In fact I have argued that play is far more important than games (though games have been receiving a great deal of educational interest lately). [You can read a previous posting about the relationship between play and games here.

Play in my mind (and in my teaching) if often connected with humor. As it turns out, recent research indicates that this connection has an evolutionary history. As this article argues, humor is a part of our "mammalian inheritance, and [is] closely related to rough-and-tumble social play.” Read the rest of this entry »
