Diagnostic assessment

The 'rip, mix, burn' model of pedagogy (see post 14th November 2010) is very compelling but it fails to provide any guidance about assessment.



Edinburgh Castle
Imagine if a person phoned you up and asked you for directions to travel to Edinburgh. I might say: go the the Black Cat roundabout and turn left; continue north up the A1 until you reach Edinburgh. These instructions would be wrong for people travelling from Inverness, Glasgow, London or Cambridge. The first thing to do would be to find out where they were.

You must assess before you teach. If you don't know where a person is in their learning you can't personalise their teaching. Much of what you do teach will be wasted. Your students won't end up where you want them to. Some will get very lost indeed!

MRI scanner
In the 19th Century, medicine shook off the shackles of quackery. Doctors learnt to diagnose. They used technology (thermometers, stethoscopes, etc) to measure key indicators of health. As time moved on they developed more and more high tech diagnostics: X-ray machines, blood pressure cuffs, blood tests, MRI scanners.

By and large education retains the pencil and paper test. These give next to useless information. I attended a parents' evening where the Maths teacher was armed with a formidable array of numbers about my stepdaughters' Maths. What do the numbers mean? I asked. She wasn't very good at Maths. Which bit of Maths? I asked. Maths generally, I was told. What does she need to do to improve? I asked. Try harder and ask for help, I was told.

At least the Maths teacher had tried. Most of the teachers that evening had measured nothing and simply spoke in platitudes. I can't imagine a doctor giving me such vague replies.

So my utopian vision for the future of education is to use technology to improve our diagnostic assessment.

Using a 'rip, mix, burn' metaphor for learning

This is an expansion of an earlier blog and a position paper.


This paper is divided into three parts:
  • An explanation of the rip, mix, burn metaphor
  • Using the metaphor as a model for learning, considering the perspectives of Sanger, Thornburg, and Gladwell
  • Further questions to explore the metaphor
The rip, mix, burn model
Manovich (2005) points out that traditionally, education flows from a source to a receiver; in education the teacher transmits knowledge to the student in the hush of the classroom.  However, he believes that in education 2.0, knowledge is collaboratively constructed through multiple dialogues, as at a party. He sees this as the 'remixing' of knowledge and finds precedents in the merging of cultures as when Rome conquered Greece or the renaissance rediscovered the classics. 

Baraniuk (2006) notes that the LP has been superseded by a digital music culture which is characterised by a creative process of rip, mix and burn. 

Ripping is defined by wikipedia as a "process of copying". In some contexts such as where intellectual property rights exist this can be illegal.  In other cases it can be unethical (eg in an academic context unattributed copying is plagiarism).  But Blakley (2010) points out a "culture of copying" makes the fashion industry massively innovative.

Mixing or remixing is the creative part of the process.  An audio track can be remixed by breaking it down into its components, subtracting some and adding others. Shakespearean plays are often remixed by reinterpreting them into a new context; the extent to which this is done can lead to the new version being regarded simply as a new edit or as a work in its own right such as Verdi's Otello or Porter's Kiss Me, Kate

Burning is the process of recording the audio track.

Expanding the metaphor
I want to reinterpret (which is in itself a type of remixing) this process as a metaphor about learning. Specifically, I want to explore ripping as the transmissive aspect of education, mixing as the collaborative aspect and burning as the production of the end product.

Sanger (2010) explores the difference between information and knowledge. An unread text represents information but it is not until the student has learned it by reading it and understanding it in the context of the student's schema that this information becomes knowledge. The reading (the 'ripping') is not enough. The student needs to remix it by analysing (disassembling) the text, examining each component, and then synthesising the new ideas with their own previous knowledge before it can be burned into their brain. 

Although Sanger (2010; p20) attacks collaborative learning ("It is one thing to engage in a discussion .... but it is quite another to think creatively and critically for oneself"), he is not attacking the belief that dialogues and structured conversations can facilitate learning. Considering ideas from alternative points of view is an important strategy in mixing. As Cascio (2009) suggests, a "proliferation of diverse voices may actually improve our overall ability to think." I think Sanger is saying that the iconic status of collaborative learning is blinding people to the fact that mixing is not enough; that ripping and burning are essential parts of the process of learning.
I think Sanger would see parallels between his ideas and those of Thornburg (2004). Thornburg suggests that in our hunter-gatherer past there were three types of primitive pedagogy:
  • The campfire around which an elder of the tribe sat and told stories which has evolved into the lecture or the presentation; transmissive education or ripping;
  • The watering-hole where people gossiped which has evolved into the seminar, the campus-cafe or the academic common room; collaborative co-construction of understanding, or mixing;
  • The cave where individuals sat and thought through the long, dark, lonely nights which has evolved into the study-bedroom; for Sanger this is the "essentially solitary"  moment when learning is achieved.
Sloman (2001; p116) adds a fourth pedagogy to Thornburg's triad:
  • The hunting party where young hunters honed their skills under the supervision of the old has evolved into the lab.
This is useful because there are some aspects or types of learning where discussion is not enough and where practical activities take precedence so I see Sloman's hunting-party as an alternative to or an elaboration of Thornburg's watering-hole. 

So learning appears to be a three-part process:
  • Ripping at the campfire where ideas are transmitted;
  • Mixing at the watering -hole or on the hunting-party where ideas are pulled apart, examined from different perspectives; and reassembled in novel ways;
  • Burning in the cave where learning is consolidated.

Perhaps we can understand this better if we see learning as a process of disturbing the equilibrium of a system. Gladwell (2000; p259) believes that what he calls social epidemics depend on three sorts of people: 
  • ‘Connectors’, who cultivate friendships;
  • ‘Mavens’, who have acknowledged in-depth expertise such that other people will take their advice;
  • ‘Salesmen’, who know how to persuade.
In the twittersphere, Connectors will have lots of followers and will also follow lots of others; Mavens will follow a lot of others but not have many followers; and Salesmen will follow few but have lots of followers.

Rather than see these as three different sorts of people, let us imagine them as one person undergoing the three stages of a learning process. In the transmissive phase you are trying to learn so you greedily suck information in from wherever you can; you are a Maven, you follow many. In the mixing phase you want to discuss your ideas as widely as possible, to rip them up and cast them upon the waters and see what comes back. This is the Connecting phase. Finally you burn your ideas by Selling them to as many people as possible.

This should also be true for good e-learning:

  • Information is presented to students using text, video, slide presentation or audio podcast (many authorities seem to concentrate entirely upon this transmissive, instructional process);
  • The students discuss the information using chat rooms, discussion forums, wikis, or sl seminars
  • The students then create their own paper, or blog, or artefact.

Exploration of concepts around the metaphor

Ripping

What exactly is the ripping process? It is more than just the passive receipt of transmitted knowledge? If we compare learning to the creation of a meal, ripping is the assembling of the ingredients. As such there is an important element of selection about it. We need to know what to rip. We choose whom to follow on twitter and google reader.

In this contest we can understand some aspects of the role of the teacher in this ‘ripping’ phase. He is the transmitter of knowledge, the storyteller, the sage on the stage. As such he needs performance and presentation skills to improve the “stickiness” of the information he is presenting (Gladwell 2000; p259). But in this role he has also selected the ingredients of the knowledge meal he is serving. Of course, more mature or more self-directed learners will expect to choose their own ingredients. Perhaps the art of teaching is guiding the learner to make the ‘right’ selection.

What should the ingredients look like? Do they need to be chopped up? If so how big should the chunks be? There seems very little objective research done on how long a lesson should last and teacher surveys seem to suggest that the ideal length is:
  • Whatever the teacher has been used to;
  • Dependent on the pupil age;
  • Dependent on the subject.
On the other hand, the popularity of Twitter has led to speculation that mixing very small bits of knowledge might improve learning. Jarche (2010) suggests that small bits will engender more creative mixes: “Twitter strips bare our communication by limiting it to 140 character bursts which gradually meld into a stream from which patterns emerge. These patterns are not intended or designed by the originator, but sensed by the observer.” Junco et al (2010) show that using Twitter increases grades among college students although this seems to be due to increased engagement in the mixing part of the learning process. The knowledge they were seeking to transmit was normal sized although an abstract of their paper helpfully uses sections of no more than 140 characters.


Rankin (2009) considers to what extent size matters in her Twitter based Political Science class: “140 characters does limit the types of comments that they’re able to make and the types of evidence and argument that they’re able to make to back up their opinions and there are some issues that we’re discussing in class that do require a more in-depth approach towards explaining one’s position but on the other hand oftentimes there’s a lot of miscellaneous information that students think they need to throw in the kind of muddle up the idea they’re trying to portray so having to keep them limited to 140 characters does require students to get at the absolute central point.”

One of the 'Laws of Mind Mapping' is to use single words. Chambers (2009) suggests that  “a single word can come up with far more associations than a phrase or a sentence can. A sentence locks the meaning of a word into a very restrictive area whereas the word on its own can generate far more ideas.”



Mixing

In the alchemy of learning, mixing is perhaps the most obscure phase. Is it like a chemical reaction in which the selected reactant molecules encounter one another, break their interatomic bonds, rearrange and rebond to form new products? Is it like cooking in which you process the ingredients using a variety of techniques at a variety of temperatures for a variety of times? In other words: what are the conditions under which collaborative ‘watering-hole’ learning is most effective?

Does mixing have to be interpersonal? To some extent it must be, because the ideas that are being mixed will have arisen from different people. But the ideals of collaborative learning, which seems to be the paradigm of the waterhole, are that people learn if they discuss and debate. Black (2000; p409) talks about “enrichment through communal interaction” and Shirky (2008; p109) states that "Collaborative production, where people have to coordinate with one another to get anything done, is considerably harder than simple sharing, but the results can be more profound." (p109) Nevertheless it is clear to me as I write this paper that I am mixing ideas and learning whilst totally solitary. Equally the ‘hunting party’ mode of learning suggested by Sloman (2001; p116) which I suggested could be an alternative to the watering-hole could also be undertaken alone. In this case one is testing one’s ideas against something external, as a scientist tests his theories against nature.

To what extent should the ingredients be compatible? Do the pieces have to have an affinity for one another? It is clear that it is difficult to mix two cultures that are very different; it engenders misunderstanding, distrust and hostility. On the other hand, there is nothing to be gained by mixing two components that are identical. For a learning event to occur, the components have to be different but not too different. Is there an ideal degree of difference? Perhaps it is like a network. Krebs (2010) states that in a network, more than two steps is considered to be ‘over the horizon’: “After one step the message begins to grow fuzzy, after two it is becoming very noisy, and after three it is basically useless -- background hum. We might be all separated by six degrees but it is the first two steps that really matter." But how do we determine the degree of difference for two items of knowledge?



Schank (2010) believes that telling stories is what we do which links in very well with Thornburg's camfire. But Schank also says: "Comprehension means mapping your stories onto my stories and vice versa. .... You can't really communicate very well with someone whose stories are very different." (10m30s)



Presumably it is the extent to which the ideas are compatible which will reinforce or answer Sunstein’s (2007) concern that the movement towards personalisation will lead to each of us entrenching our positions within our mental ghettoes.

If we continue to think of learning as a network we might also consider the analysis of social networking conducted by Shirky (2008) in which he deduced a power law governing the amount of participation; compatible with the Long Tail as described by Anderson (2006).

Is learning like crowdsourcing in which a community of users develop ideas, for example the Global Ideas Bank (http://www.globalideasbank.org/site/home/). Is wiki or open source software development like learning?

Burning

In some ways burning seems to be the most trivial part of learning. I am presently burning my ripped and mixed ideas into this essay although I am conscious I am still mixing as I write (and I regularly follow up an idea online to rip another thought). Burning is more than just serving the cooked meal? It is a truism that you never really understand a subject until you have taught it. Burning involves the crystallisation of thought; it is the process of the learner taking ownership of the ideas he is learning.

What are the ideal conditions for burning? In my case it is quiet, solitude and a lot of walking (I wander corridors at work when I am thinking). Are the creation facilities offered by the web (blogs, writing tools, artefact creation tools) necessary or appropriate for burning?

Summary

I have tried to show that a ‘rip, mix, burn’ metaphor for learning mirrors, to some extent, the process of learning. I have explored some of the details of this model in greater detail and have posed a number of questions which I hope might stimulate further thinking and concept creation.

How long should a lesson last?

It is surprisingly difficult to find an answer to this. Of course, to some extent it depends upon context but there seems to have been very little research done.


Most research seems to consist of asking teachers how long they think a lesson should last. On the whole they seem to suggest that the length of lesson to which they are most used is the best length.


So perhaps we should scrutinise research from psychologists which tell us about attention span. For example, research using the pre-school TV programme Sesame Street has shown that “no single segment … should go beyond four minutes, and that three minutes was probably optimal.” (Gladwell 2000; p104)

Of course, this applies to pre-school children. It also tells us how long a 'segment' should last. The programme, like a lesson, is constructed from many segments: Sesame Street lasts an hour (minus adverts etc).

THIS PAGE IS STILL BEING CONSTRUCTED

It also showed that five-year-old children distracted with toys watched half the time that children without toys watched but “the children remembered and understood … exactly the same” because they view strategically. (Gladwell 2000; p101)

Networks

If the 'rip, mix, burn' model of education (see my post of the 28th October) is valid then it is worth investigating the 'mix' phase. Mix is when ideas come together. One way of doing this is by bringing together people who have different ideas (another way is by one person reading lots of different books!).


Presumably, if the ideas are too different, there will only be incomprehension and misunderstanding. It is like two cultures coming together when people fight rather than trades. It is like listening to jazz for the first time; it sounds like a cacophony. So there has to be some common ground. But if the ideas are too similar there won't be sufficient mix. Thomas Kuhn's Structure of Scientific Revolutions might distinguish between the creeping progress phase when the ideas are very similar and the revolutionary phase.


Networking is a way of bringing people together. The power of Facebook shows how much people enjoy (social) networking. Other websites, such as LinkedIn, exist to encourage professional networking. The rise of the coffee house gave birth to Lloyds but it was probably also responsible for the rapid spread of ideas that became known as the Enlightenment and gave us the scientific, political and commercial concepts on which the modern world is based. 


Reinelt (2010) suggests that "Networks scale when people in networks reach across divides (e.g., race, sector, issue, interest) and build bridges that enable them to exchange ideas, share resources, and collectively self-organize to influence fields and policies. Boundary-spanning begins with conversations to find connections. These connections form clusters that lead to stronger webs of relationships and eventually robustly link networks to other networks -- a fundamental prerequisite for scaling. " 


Ricchiuto 2010 offers the 4 Laws of social networks:

  • Serendipity "happens at the intersection of (network) consciousness and being transparent about one's gifts and passions"
  • "Innovation happens at the intersection of learning and cultivating diverse connections"
  • "Influence happens at the intersection of credibility and location in the network"
  • Networks grow when there are many introductions and the people who are introduced are generous, giving without expecting reciprocity.
This tells us little other than that Ricchiuto believes that networks work if the people in them are transparent, generous and credible; if they cultivate diverse connections and make intorductions; and if they are ready to learn. 



Malcolm Gladwell (2000; p259) lists the factors that cause what he calls social epidemics: "We are powerfully influenced by our  surroundings, our immediate context, and the personalities of those around us .... Merely by manipulating the size of a group, we can dramatically improve its reception to new ideas. By tinkering with the presentation of information, we can significantly improve its stickiness. Simply by finding and reaching those few special people [people who cultivate friendships; people who have acknowledged in-depth expertise such that other people will take their advice, and people who know how to persuade] .... we can shape the course of social epidemics." 


For Gladwell, therefore, networks need to be the right size, and in the right context, and the people  in them need to be well-connected, persuasive and acknowledged experts. It also helps is the information is 'sticky'.


Krebs (2010c) created a network map showing the political affiliations of the candidates in the 2010 NY gubernatorial race: it dramatically illustrates a partisan politics. A network like this is going to create disturst and misunderstanding rather than the 'mix' phase of learning.








One of the things we know about networks is that they generate feedback loops. In another posting, Krebs (2010b) points out that positive feedback created the bubble in the sub-prime mortgage market that led to collapse. This is easy to spot in hindsight; why couldn't the players within the feedback loops spot the dangers earlier? His suggestion is that each part of the feedback loop was below the 'network horizon' of the other part. "In networks, any path longer than 2 steps is usually considered "over the horizon" -- one cannot see, nor influence, over the horizon. In networks, distance leads to distortion, delay, and increased risk."


He has already explained this idea in an earlier post (2010a)."After one step the message begins to grow fuzzy, after two it is becoming very noisy, and after three it is basically useless -- background hum. We might be all separated by six degrees but it is the first two steps that really matter." He also points out that nodes in the network differ in how quickly they pass on information. So if you want to get your message out there DON'T rely on a single connector or maven; get your message to several nodes in different parts of the network or as Krebs puts it: build in redundancy.


This delay idea leads me to think of the beer game described by Senge (2006). In this modelling of inventory stocks it is an inbuilt delay in receiving information which leads to disastrous stock fluctuations. 


If you consider twitter as a network there are perhaps three sorts of tweeter:

  • Those who follow many and are followed by a few: these tweeters learn a lot and develop a great deal of expertise: in Gladwell's terms these are the mavens who collect knowledge and therefore develop a reputation for expertise: their followers listen to them;
  • Those who follow a few but are followed by many: these are the salesmen, the persuaders
  • Those who follow many and are followed by many: these are the connectors

Might also be worth reading this post (14th December 2009)

Using QR codes and barcodes in school

This is the QR code for this blog. It was generated using a website called Kaywa. Anyone with a free bar code reader on their smartphone can scan this and be linked to this blog.


Another QR code generator, called snap.vu lets you create and download a QR code to match a website address. It will then email you so you can keep track of how many times your code has been accessed.




"Stickybits allows you to not only access ‘stuff’ attached to a barcode, but you can also add your own ‘stuff’. By ‘stuff’, I mean anything (anything electronic): documents, photos, video clips, audio files etc – the list is endless. Adding stuff can be done on the hoof (via the device itself) or via the website – browse>upload. Stickybits allows you to create (for free) your own unique barcodes but also to add stuff to any existing barcode (a 500ml bottle of Coke has loads of stuff attached to the barcode)." McCormick 2010


How can we use these at school? 

Extend learning outside the classroom.  "The corridor outside the history class could have colourful posters on the wall but also a QR code that would give access to a multimedia display about the topic for this month." but you could extend right across the school site and beyond (libraries, community notice boards, even hairdressers and supermarkets) (Bretag 2010). McCormick (2010) suggests that this would enhance tours of the school! 

Posters of poems could have podcasts of the poem; posters of composers could have podcasts of their music. Every element on a poster of the Periodic Table could have a link to wikipedia or a video about the element (Kimberley 2010).


Use it to offer confidential services. "A QR code on the wall outside the medical centre might allow students to access contact details for help and counselling services without being seen to be writing down the numbers. They wouldn't need a pen or paper either (they'd be more likely to have their smartphone)." (Bretag 2010)





Stick dedicated QR codes into text books. (Muir 2010). When a pupil reaches that page their mobile phone can give them access to images, video, audio or extra text to enhance their understanding of the work. McCormick (2010) suggests that these could be pupil generated; eg a video of a pupil explaining how they used a particular maths technique to solve a problem. Reading books could have book reviews added (McCormick 2010).

Stick QR codes into pupil exercise books so that feedback can be given on the linked dedicated website (McCormick; 2010) and Kimberley; 2010). Parents (and others) could access this; they might even be able to add comments. You might want to consider whether you want all you comments about a pupil to be available to anyone who scans a barcode in their book; this might have Data Protection implications.

A particularly powerful idea, credited  toTim Rylands is to attach QR codes to teacher resource packs so that each teacher using the pack can add to it.

Threshold Concepts and Schemes of Work

Threshold concepts open up new horizons
Most secondary subject leaders start with the exam (or national curriculum) specification; the scheme of work is therefore fundamentally content oriented. Time is allocated according to how much content has to be 'got through' in the lessons. Some allowance is made for how 'easy' or 'difficult' a topic is; this allowance is usually based upon experience.


But there are some concepts that are fundamental to understanding a subject. A pupil cannot progress in a subject until they have these concepts. For example, until a pupil understands how to manipulate algebraic equations (for example, the concept of 'balancing' and equation) they cannot progress in algebra. There is no point teaching the techniques for solving quadratic equations until they understand simple equations. 




Threshold concepts  are more difficult
than walking through a doorway.
Meyer and Land (2005) called these 'Threshold concepts'. They are:

  • Troublesome: they are hard to teach because they are difficult for pupils to understand
  • Irreversible: once they've got it, they've got it
  • Transformative: once you have crossed the threshold you can appreciate whole new perspectives on  the subject



The threshold is not just like a doorway, however. It is more like a rite of passage. Crossing through the threshold "is often problematic, troubling and frequently involves the humbling of the participant .... the transformation can be protracted, over considerable periods of time, and involve oscillation between states, often with temporary regression to earlier status." (Meyer and Land 2005; p376)


Pupils can get stuck.  This can be a good thing. Pirsig (1974; p279) points out that  "Stuckness shouldn't be avoided. It's the psychic predecessor of all real understanding". 


But pupils don't like being stuck (problematic, troubling, humiliating) and teachers try to ease their pain. This can lead to teachers teaching tricks to get around the conceptual difficulties.  For example, Bransford (2000) gives the example of  "a man who needed three-fourths of two-thirds of a cup of cottage cheese to create a dish he was cooking. He did not attempt to multiply the fractions as students would do in a school context. Instead, he measured two-thirds of a cup of cottage cheese, removed that amount from the measuring cup and then patted the cheese into a round shape, divided it into quarters, and used three of the quarters." They point out that this technique would not have worked for fluids, nor would it have been necessary had the man understood that two-thirds of three-quarters equals one-half; he only needed to use half a cup.


Dumbing down a concept by deliberately simplifying it leads pupils to  "settle for the naive version ... entering into a form of ritualised learning" (Meyer and Land 2005; p382).


So what should we do about Threshold Concepts?



  1. Stop thinking about your subject in terms of the content. See it as concept-based. 
  2. Identify the Threshold Concepts: they are the ideas that are troublesome, irreversible and transformative.
  3. Design the scheme of work around these Threshold Concepts. Allocate sufficient time to them. They are the steep hills that have to be climbed. There will be flat parts along which you can race.
  4. Design activities that are going to meet the Threshold Concepts head on and help the students to explore the ideas whilst they construct their own understanding of them.
  5. Support your students as they struggle with the Threshold Concepts. Be prepared for tears!

The school bus

For many students, being at school is like being in a bus.

  • It is an essentially passive experience.
  • The route is pre-planned.
  • The timetable is preplanned.
  • Someone else does the driving.
  • They don't have to concentrate.
  • They sit and chat, or stare out of the window.





Driving yourself in a car is a completely different experience!

  • You might look at a map, but you decide where you are going.
  • You also decide when to start and when to finish your journey.
  • You can stop and take a break if you want.
  • You can take a detour if you decide there is something you want to investigate.
  • You have to concentrate hard!

Young people really, really want to learn to drive. They will pay hundreds of pounds to learn.

Driving represents freedom and personal choice.

Pupils would be more motivated and concentrate harder if schools were less like buses and more like cars.

The Subway Curriculum


The Subway menu  offers two sizes, 5 breads, 17 fillings, each with cheese or no cheese, each toasted or not toasted, any selection of 8 salad fillings and 7 sauces. When I enter a Subway I am faced with a choice of one sub from an awesome 191,923,200 possibilities.





Imagine if a pupil could walk into a class and be given that range of choice. 
Actually that is only 1,920 possible choices. But it would be a start.

In a talk to the RSA, Sir Ken Robinson has pointed that we model our schools on factories; the most important feature of a pupil is his age, which Sir Ken calls "the date of manufacture". We teach batches. Our quality control is built around the model of standardisation: teachers have to follow a prescribed curriculum using recommended pedagogies; students are expected to meet targets set on the basis of what other students of their age are meeting.

On another talk (to TED in 2010) Sir Ken says "We have built our education systems on the model of fast food". But what we offer pupils is worse than that. Subway trumps school.

Is 'rip, mix, burn' a model for e-learning?

Remix: Leonardo's Last Supper reinterpreted by the Simpsons.
Manovich (2005) points out that traditionally, education flows from a source to a receiver; in education the teacher transmits knowledge to the student in the hush of the classroom.  However, in education 2.0 
knowledge is collaboratively constructed through multiple dialogues, as at a party. He sees this as the 'remixing' of knowledge and finds precedents in the merging of cultures as when Rome conquered Greece or the renaissance rediscovered the classics. 



Baraniuk (2006) notes that the LP has been superseded by a digital music culture which is characterised by a creative process of rip, mix and burn. 


Ripping is defined by wikipedia as a "process of copying". In some contexts such as where intellectual property rights exist this can be illegal.  In other cases it can be unethical (eg in an academic context unattributed copying is plagiarism).  But Blakley (2010) points out a "culture of copying" makes the fashion industry massively innovative.


Mixing or remixing is the creative part of the process.  An audio track can be remixed by breaking it down into its components, subtracting some and adding others. Shakespearean plays are often remixed by reinterpreting them into a new context; the extent to which this is done can lead to the new version being regarded simply as a new edit or as a work in its own right such as Verdi's Otello or Porter's Kiss Me, Kate


Burning is the process of recording the audio track.


I want to reinterpret (which is in itself a type of remixing) this process as a metaphor about learning. Specifically, I want to explore ripping as the transmissive aspect of education, mixing as the collaborative aspect and burning as the production of the end product.


Sanger (2010) explores the difference between information and knowledge. An unread text represents information but it is not until the student has learned it by reading it and understanding it in the context of the student's schema that this information becomes knowledge. The reading (the 'ripping') is not enough. The student needs to remix it by  analysing (disassembling) the text, examining each component, and then synthesising the new ideas with their own previous knowledge before it can be burned into their brain. 


Although Sanger attacks collaborative learning ("It is one thing to engage in a discussion .... but it is quite another to think creatively and critically for oneself"; p20) he is not attacking the belief that dialogues and structured conversations can facilitate learning. Considering ideas from alternative points of view is an important strategy in mixing. As Cascio (2009) suggests, a "proliferation of diverse voices may actually improve our overall ability to think." I think Sanger is saying that the iconic status of collaborative learning is blinding people to the fact that mixing is not enough; that ripping and burning are essential parts of the process of learning.


A typical student watering-hole
I think Sanger would see parallels between his ideas and those of Thornburg (2004). Thornburg  suggests that in our hunter-gatherer past there were three types of primitive pedagogy:
  • The campfire around which an elder of the tribe sat and told stories which has evolved into the lecture or the presentation; 
  • The watering-hole where people gossiped which has evolved into the seminar, the campus-cafe or the academic common room;
  • The cave where individuals sat and thought through the long, dark, lonely nights which has evolved into the study-bedroom; for Sanger this is the "essentially solitary"  moment when learning is achieved.
Sloman (2001; p116) adds a fourth pedagogy to Thornburg's triad:

  • The hunting party where young hunters honed their skills under the supervision of the old has evolved into the lab.
This is useful because there are some aspects or types of learning where discussion is not enough and where practical activities take precedence so I see Sloman's hunting-party as an alternative to or an elaboration of Thornburg's watering-hole. 

So learning appears to be a three-part process:
  • Ripping at the campfire where ideas are transmitted;
  • Mixing at the watering -hole or on the hunting-party where ideas are pulled apart, examined from different perspectives; and reassembled in novel ways;
  • Burning in the cave where learning is consolidated.

This should also true for good e-learning:
  • Information is presented to students using text, video, slide presentation or audio podcast (many authorities seem to concentrate entirely upon this transmissive, instructional process);
  • The students discuss the information using chat rooms, discussion forums, wikis, or sl seminars
  • The students then create their own paper, or blog, or artefact.
