Flexible Disciplines, Flexible Boundaries, and Making Meaning

I think I have a bit more to say about boundaries, especially in terms of the boundaries that distinguish the academic disciplines. I've been arguing that the boundaries between, say, history and physics are nowhere near as rigid and as static as academic purists might insist, but neither are the boundaries between history and physics imaginary, capricious, and unnecessary as academic anarchists might insist. (I recognize that I am creating extremes with my contrast of purists and anarchists and that most educationists lie somewhere between or even outside these two extremes, but it helps me to see my point.) Boundaries are both necessary for human activity and knowledge and temporary.

I rely here on a few articles by South African complexity scholar Paul Cilliers and by Dave Snowden's Cynefin Framework, and my argument, I think, makes a basic assumption: that education and educational structures are complex systems tending to the chaotic, rather than complicated systems tending to the simple. I believe this is so despite the enormous energy expended in wrenching education into a simple system. Education ain't simple. It probably isn't even complicated. It's complex, at best. To my mind, then, the biggest problem with academic disciplines is that we try to move them into the simple and/or complicated domains of the Cynefin Framework where their boundaries are fixed, explicit, and easily taught, with clear canons of content and methodologies. In the simple or even complicated domains, it's easy to distinguish the historian from the physicist. In the complex domain, disciplinary and canonical boundaries are much more problematic, though no less useful, even necessary. Paul Cilliers helps me understand this.

In several critiques (Knowledge, Complexity, and Understanding (2000), Knowledge, limits and boundaries (2005), and Why We Cannot Know Complex Things Completely (2007), for instance), Cilliers argues that knowledge is best understood as an emergent property "constituted within a complex system of interactions". This view of knowledge avoids both extremes of the purist and the anarchist, or as Cilliers more accurately calls them: the fundamentalist and the relativist. As Cilliers says:
An understanding of knowledge as constituted within a complex system of interactions would, on the one hand, deny that knowledge can be seen as atomised ‘facts’ that have objective meaning. Knowledge comes to be in a dynamic network of interactions, a network that does not have distinctive borders. On the other hand, this perspective would also deny that knowledge is something purely subjective, mainly because one cannot conceive of the subject as something prior to the ‘network of knowledge’, but rather as something constituted within that network. The argument from complexity thus wants to move beyond the objective/subjective dichotomy. (Knowledge, limits and boundaries, p. 608)
Knowledge, then, is not representational, "linked to the sign which represents it", but relational, "the result of a dynamic interaction between all the meaningful components in the system … itself a complex process" (Why We Cannot Know Complex Things Completely, p. 85). This presents an immediate problem, however, given the open nature of complex systems. If complete knowledge must account for an infinite number of interactions across the open boundaries of complex systems, then how do we ever attain actionable knowledge, given that we have a limited amount of time? Because we, as knowledge makers, are ourselves contextualized, and each context limits the number of system components presented for knowledge making. In other words, though a single rose is ultimately connected through its complex interactions to the entire rest of the Universe, the meaning of the rose is constrained when I cut it from my own garden and present it to my wife on Valentine's Day, which provides a bounded context within which meaning can emerge. The boundaries make the emergence of a particular meaning possible.

Of course, the meaning is no more absolute than the boundaries that enable it. In the relatively straightforward example above, the meaning of the rose will be slightly different, perhaps radically different, for me than for my wife as we bring our different contexts to the event, but it will be similar enough that we can at least speak meaningfully with each other—though we should be mindful that the very stuff of most romantic comedies involves the different meanings drawn by men and women from even so well-bounded and commonly shared an event as Valentine's Day. Boundaries in complex systems are not permanent or rigid, though they can persist in recognizable contours for long times.

So to directly address my concerns with Marion Brady's dismissal of disciplinary boundaries, I think he slightly overstates his case. We cannot dispense with boundaries in complex systems such as academic disciplines if we want to create meaning, or knowledge. Likewise, we cannot calcify our boundaries without destroying knowledge. As Cilliers says it:
One can, and often should, emphasise the interrelatedness of systems. Often the boundaries of systems are constructions we impose in order to reduce the complexity. This can lead to oversimplifications, to reductive descriptions of the system. However, if boundaries become too vague, we end up with a kind of holism which does not allow much to be said. … We need limits in order to say something. (Why We Cannot Know Complex Things Completely, p. 88)
Perhaps, though, Brady's discontent with disciplinary boundaries comes from the usual interpretation of boundaries as "something that separates one thing from another" (Knowledge, limits and boundaries, p. 611). In this view of boundaries, one cannot be both an historian and a physicist at the same time. History and physics are separate things, and one cannot be in both places at once. Of course, complexity and quantum theories ignore this kind of classical logic. Cilliers makes some suggestions about how we might think differently about boundaries, ways that make sense within complex systems.

First, "we should rather think of a boundary as something that constitutes that which is bounded. This shift will help us to see the boundary as something enabling, rather than as confining" (p. 611). From this view, our skins, those well-known and most familiar boundaries, don't separate us from the rest of the world; rather, they enable our interaction with the world by helping to maintain our own integrity as a persisting complex system and providing somewhat stable and recognizable contours that the rest of the world can engage and through which energy and information may be exchanged. Likewise, disciplinary boundaries need not separate historians from physicists, but they should enable useful, valuable interaction between historians and physicists, shifting and stretching as different issues supply different contexts of meaning, again enabling a mutually valuable exchange of energy and information.

Next, we should rethink our physical images about the place of a boundary. We must replace our visual metaphors which force us to think of complex systems "as something contiguous in space." Complex social systems, Cilliers notes, are not necessarily contiguous; thus, "parts of the system may exist in totally different spatial locations." This is certainly the case with history as an academic discipline, which is not a spatially contiguous physical system. This implies that a historian likely belongs to many different complex systems (families, churches, political parties, etc) and "that different systems interpenetrate each other, that they share internal organs." So where's the boundary? It's always provisional, determined by the context referenced at any given time for any given event. Furthermore, Cilliers notes that any node in a system is "never far away from the boundary. If the components of the system are richly interconnected, there will always be a short route from any component to the 'outside' of the system. … the boundary is folded in, or perhaps, the system consists of boundaries only. Everything is always interacting and interfacing with others and with the environment; the notions of 'inside' and 'outside' are never simple and uncontested" (p. 611).

So maybe that can address Brady's concerns with disciplinary boundaries. At least somewhat.

cMOOCs & Temporary, Emergent Boundaries

In my last post, I quoted Marion Brady's observations about the transdisciplinary nature of thought and learning, what he calls Theory R: "Theory R requires students to make connections, to perceive relationships, and to synthesize ideas. It sends students searching the far corners of their minds without regard for the artificial, arbitrary boundaries imposed by academic disciplines." I think I understand Brady's point about and his disdain for the "artificial, arbitrary boundaries imposed by academic disciplines." I am entranced with transdisciplinarity and agree with the need to transcend boundaries that are too often impediments to learning and research, but I think Brady overstates the case, ignoring the necessity of boundaries for knowledge and action.

I recently came across Kurt A. Richardson's 2001 article On the Status of Natural Boundaries: A Complex Systems Perspective which helps me clarify my thinking on this issue. Richardson uses complexity theory to guide him through the dilemma of reductionism on one hand, in which boundaries are clear, discrete, and persistent, and holism on the other hand, in which boundaries disappear altogether as everything merges into the Universe or God.

Richardson begins by making a very useful distinction between complex and complicated systems. He states that he is concerned with complex systems, which he defines neatly:
A complex system is comprised of a large number of non-linearly interacting non-decomposable elements. The interactivity must be such that the system cannot be reducible to two or more distinct systems, and must be sufficient (where the determination of sufficient is problematic) to allow the system to display the behaviours characteristic of such systems. (p. 230)
He then clarifies the difference between these complex systems and the often similar looking complicated systems:
The principle difference between a complicated system and a complex system is not the presence of large numbers of entities and nonlinear interactions. The key difference is the nature of the overall connectivity, particularly the existence of feedback mechanisms. Despite the existence [of] nonlinearity complicated systems do not self-organise into new structures. They do not display a wide range of qualitatively different behaviours. The extent and nature of the nonlinear interactivity is what differentiates between a complicated and complex system. The division between these two categories at a compositional level is very blurred however. It is problematic to know from compositional information whether a system is complicated or complex without having information about its behaviour. Complicated and complex systems, then, can only safely be differentiated from each other by observing their respective behaviours.
A complicated system, then, is like a modern jet fighter: large numbers of entities with a myriad of interactions, including some nonlinear interactions, among its parts; however, the jet fighter is incapable of evolving, or self-organizing into new structures.

This distinction between complicated and complex systems helps me to understand the traditional classroom and the value of cMOOCs. A traditional school is a complicated system composed of large numbers of entities and interactions. Some classes are complicated systems, say those with students exceeding Dunbar's Number, but most are simple systems composed of a fixed number of entities (1 teacher and 25 students) and a few, mostly linear interactions: curriculum + instruction —> student learning. In such simple/complicated systems, boundaries are fixed, clear, and enforced. The subsystems (teacher, students, curriculum, lessons, texts, etc) are rigidly differentiated and the interactions among them are stable, predictable, and enforceable. The boundaries are in place and real, and any blurring of a boundary is considered a failure by purists or as a daring experiment in free learning by rebels. Either way, the reality of the boundary is reinforced. Violating a boundary confirms the boundary just as much as enforcing the boundary.

cMOOCs, unlike traditional classrooms and xMOOCs, are intentionally complex systems. cMOOCs and xMOOCs are differentiated by their respective behaviors. Like xMOOCs and some traditional classes, cMOOCs have large numbers of entities with a myriad of interactions, but unlike those complicated systems, cMOOCs can and do self-organize into different and new structures. They evolve through nonlinear interactions, feedback loops, non-local causalities, dialogic tensions, and a range of other behaviors characteristic of complex systems, and new structures of people and ideas emerge that could not have been anticipated by the designers of the MOOC. These complex interactions unfold across blog posts, tweets, Youtube videos, Flickr posts, and coffee cups, and new patterns of people and ideas emerge out of the interactions. Boundaries in cMOOCs, as in other complex systems, are different than the boundaries in simple and complicated systems.

Complex systems, then, are difficult to evaluate. Simple/complicated systems, with their fixed entities and interactions, have a strict linear progression which leads to a predictable, and usually measurable, outcome (if a teacher does A + B + C, then the student must learn D, which we can measure on a test and repeat A + B + C until the student learns D). However, as Richardson points out, complex systems "display many possible qualitatively different behavioural regimes (the nature and variety of which evolve), as well as exhibiting emergence, i.e. the emergence of macroscopic system structures and behaviours that are not at all obvious from their microscopic make-up … The order parameters that best describe the current behaviour of a complex system are not fixed, they evolve qualitatively as well as quantitatively." Factor in the butterfly effect (systemic sensitivity to initial conditions), and it's easy to see how difficult it becomes to predict the outcomes of any given cMOOC. This inability to predict outcomes changes the nature of evaluation. If we do not have a fixed, predictable outcome, then how do we measure the efficacy of the instruction?

Well, I seem to be slipping away from my original point about boundaries, but only a bit. A fixed, predictable outcome is a kind of boundary. It is an endpoint, a destination. In a traditional class or xMOOC, that boundary is discrete. A cMOOC does not have an endpoint or destination. Rather, it is more like another complex system, thunderstorms. Like thunderstorms, cMOOCs build in intensity, form their new structures (not random, but not totally predictable either), expend their energy, and subside, though they can continue to echo long after the thunder has stopped. So here's Richardson's main point about the distinction between complicated and complex systems: "the boundaries describing subsystems in a complicated system are prescribed and fixed whereas the boundaries delimiting subsystems in a complex system are emergent and temporary."

Anyone who has been in a cMOOC can see this fluidity of boundary, for instance, in deciding who is a student in the MOOC and who isn't. If you define student as someone who is actively participating in the MOOC, then that shifts wildly from week to week as people engage, disengage, get distracted, re-engage. And who's the teacher? That can be slippery as well. You can easily measure and quantify enrollment in a traditional class. Measuring a cMOOC is more like measuring a thunderstorm. Just when is a cloud part of the thunderstorm, and when isn't it? That can be hard to quantify or even qualify. The boundary keeps shifting as the thunderstorm, or cMOOC, evolves in its phase space. Come to think of it, developing procedures for defining the phase space of a cMOOC might be a fine start to evaluating them, but it's beyond my abilities.

So what does Richardson say about boundaries in complex systems? In short: "The only real absolute boundaries in a complex system are those that define the basic constituents and their interrelationships. All other boundaries are emergent and temporary. In order to relate these arguments to the real world it is assumed in addition that the universe is a complex system, i.e. the one and only well-defined system." He's having his cake and eating it, too, which is entirely permissible. The only complex system with absolute boundaries is the Universe itself. All other boundaries—in other words, everything else that we know about, including superstrings—are emergent and temporary. Now, curiously enough, this includes both traditional classrooms and xMOOCs as well as cMOOCs; the difference is that cMOOCs recognize and encourage emergent and temporary boundaries and structures, while xMOOCs and traditional classrooms pretend that their boundaries and structures are permanent and in some way blessed or sanctioned.

Okay, then, let's assume for the sake of argument that boundaries really are emergent and temporary. Does that mean that anything goes, that we can create boundaries where we wish as we wish, as the constructivists would have?

Richardson says no. He insists that we do not need to resort either to a constructivism that insists that "all boundaries are created in our minds and as such do not correlate with objective reality at all" or to a naive realism that insists that our ideas "perfectly map to their espoused objects." We can map reality, and those maps are based on the interactions of two complex systems, which implies a complex interaction: natural reality and conceptual reality. As Richardson says of the relationship between the natural and conceptual:
Rather than having a fixed relationship with natural boundaries, or having no relationship at all, conceptual boundaries do have a complex and changing relationship to reality. Sometimes this link might be so tenuous as to be unusable. Sometimes this link is so strong as to give us the impression that we might actually have absolute Truth to hand.
As Richardson says, "In the field of complexity there is evidence that, though there may be no real boundaries, there are resilient and relatively stable emergent structures." Mapping the world, then in the sense of Deleuze and Guattari's cartography, is problematic, but it is not impossible. Boundaries both conceptual and natural make that mapping possible, even necessary. They also make it temporary and emergent.

MOOCs, Transdisciplinarity, and Thinking Big

In his 2004 Phi Beta Kappan essay entitled Thinking Big: A Conceptual Framework for the Study of Everything, self-described contrarian educator Marion Brady writes that "the main task of educating is to help students make more sense of the world, themselves, and others" (p. 277). He attacks the current state of knowledge as represented in the plethora of academic subjects and disciplines and insists that such a fragmented approach to knowledge will, in the words of Buckminster Fuller, "be the undoing of the society." He quotes Fuller again in a marvelous 1980s complaint to American educators: "What you fellows in the universities do is make all the bright students into experts in something. That has some usefulness, but the trouble is it leaves the ones with mediocre minds and the dunderheads to become generalists who must serve as college presidents . . . and presidents of the United States." I truly wish I had said that, but … well, he was Buckminster Fuller.

Brady then identifies the basic theory of education that underlies the fragmented, disciplinary approach to knowledge:
The present curriculum, made up as it is of separate, specialized studies, exerts considerable pressure on teachers to make major use of what could be called “Theory T.” Theory T dominates American education. … T stands for “transfer.” Those who accept Theory T believe that knowledge is located in teachers’ heads, textbooks, reference materials, and on the Internet and that the instructional challenge is to transfer it from these locations into the empty space in students’ heads. The degree of success of the transfer process can be measured with relative ease, which helps explain its broad appeal. … Evaluating performance is simple enough to allow student responses to be scored by a machine. (pp. 279, 280)
 He then contrasts Theory T with what he calls Theory R:
Theory R assumes not that students’ heads are empty but that they are full. The primary instructional challenge, then, is not to transfer new knowledge but to help students reorganize existing knowledge to make it more useful, consistent, or true and to supplement it with insights and skills that will help explain more fully what they already know.… Students in Theory R classrooms must be active processors of information. Theory T emphasizes recall; Theory R requires students to engage in every known thought process. … Theory R requires students to make connections, to perceive relationships, and to synthesize ideas. It sends students searching the far corners of their minds without regard for the artificial, arbitrary boundaries imposed by academic disciplines.
Brady gives here a neat precursor to Connectivism, I think. First, he emphasizes that each student already possesses all the neuronal networks needed for making connections, perceiving relationships, and synthesizing ideas. We teachers do not transfer anything into the imagined empty memory slots of student brains; rather, we present them with a, hopefully, coherent and engaging series of artifacts and experiences to which they may connect, perceive relationships, and synthesize ideas, or not. All too often what they connect to, perceive relationships among, and synthesize are ideas that we never taught, or didn't know we were teaching. And each student makes these connections and patterns within an ecosystem (their own life stories) that we teachers know little to nothing about, and that ecosystem, that context, provides almost all of the meaning for whatever new connections and patterns the student is weaving. This reminds me much of Paul Cilliers' definition of knowledge as "information that is situated historically and contextually by a knowing subject" (Why We Cannot Know Complex Things Completely in Capra, Juarrero, Sotolongo, and van Uden's Reframing Complexity: Perspectives from North and South, 2007, p. 85). In other words, while information may exist apart from our students as data, it does not become knowledge until the student situates that information within a context that includes themselves and that necessarily informs the information in ways we teachers cannot predict or control.

But what most impressed me about Brady's article was his observation that this process of making connections (mapping, as Deleuze and Guattari say) "sends students searching the far corners of their minds without regard for the artificial, arbitrary boundaries imposed by academic disciplines." It seems to me that Connectivism and MOOCs are wonderful vehicles for transdisciplinarity, which transcends the "boundaries imposed by academic disciplines." I know that the MOOCs I have joined have had a marvelous, transdisciplinary reach in content and participants. Though I have had some of the most engaging and rewarding conversations of my professional life, as far as I know, I have actually had no conversation with another writing teacher, aside from one colleague who shared an office with me and a few MOOCs. Almost all of my conversations have been with scholars and practitioners outside my discipline, which makes my engagement in the MOOCs most transdisciplinary.

I think I will explore this a bit more in the next few posts.

MOOCs and One-on-One Teaching

Ahh … home!

I've been away too long writing something else, and I missed my warm, comfortable blog. Fortunately, The Chronicle of Higher Education just published an article by Steve Kolowich entitled MOOC Students Who Got Offline Help Scored Higher, Study Finds (June 7, 2013, 4:55 am) that rattles me a bit, and as I have a spare hour waiting to tutor students who will not likely show this early on a Friday morning, I'll jot down a response.

Mr. Kolowich starts his article by saying:
One of the first things researchers have learned about student success in massive open online courses is that in-person, one-on-one teaching still matters. 
For online learners who took the first session of “Circuits & Electronics,” the Massachusetts Institute of Technology’s hallmark MOOC, those who worked on course material offline with a classmate or “someone who teaches or has expertise” in the subject did better than those who did not, according to a new paper by researchers at MIT and Harvard University.
The assumptions in this lede annoy me, and it injures the conversation about MOOCs. First, the statement one-on-one teaching still matters is an ugly little straw man. Who ever said that one-on-one teaching does not matter? I've been listening to hard core connectivists and MOOC providers Siemens, Downes, and Cormier for about four years now, and never once have they suggested that one-on-one teaching does not matter.

Then, use of the word teaching is misleading, especially if most of Mr. Kolowich's readers still associate teaching with teacher-centric lectures, demonstrations, and discussions. This is not the kind of teaching that the report finds evidence for; rather, the report writers say:
On average, with all other predictors being equal, a student who worked offline with someone else in the class or someone who had expertise in the subject would have a predicted score almost three points higher than someone working by him or herself.
Let's unpack this. First, connecting with someone else in the class or someone who had expertise in the subject sounds much more like self-forming, self-organizing study groups or tutorial groups than a traditional classroom. In every MOOC I have taken, these kinds of self-forming networks have been as much a part, perhaps more, of the education I received than the formal presentations. And these connections are very one-on-one. I recall wonderful blog conversations in PLENK2010 with Dave Cormier, LeRoy Hill, and Rita Kop, and more recent blog conversations in ETMOOC with Christina Hendricks and Keith Brennan. Or long walks and conversations with my office mates and colleagues Tom Clancy and Bruce Neubauer as we tried to digest those early MOOCs we attended together. See? Real people with real names. This kind of connectivity is the heart of MOOCs, and this seems to be the kind of teaching that the MIT report uncovers. Well, I'm glad they saw it—it's been there all along.

Then note that the authors report average scores almost three points higher than someone working by him or herself. Is this statistically significant? Perhaps, but just barely, I think. A not quite three points average increase is hardly a ringing endorsement for any kind of instructional strategy. Frankly, I'm surprised that they didn't find a greater difference.

Finally, I'm annoyed because I suspect that the focus of the article and the report is on xMOOCs rather than cMOOCs. Perhaps the pedagogical theories behind xMOOCs do suggest that one-on-one teaching is not important, but the practice behind xMOOCs shows otherwise. The complex connectivity at the heart of MOOCs will come out, like the rhizome that it is, but it won't look much like the traditional classroom, so let's not pander to that myth.

The Unconscious Reality

The second slippery aspect of the question do we know all of Reality refers to how we conceive knowledge. If knowledge is something conscious and mostly intellectual, then I don't think we can know all of Reality, or even much of Reality. In other words, we have experiences of the Real that we are not conscious of and can hardly represent in any language. We engage and know many things with our minds and bodies long before we become conscious of them, if we ever become conscious. For instance, if you breathe in an unhealthy swarm of influenza virus, your immune system will know it and begin mobilizing a defense long before you are conscious of the infection. Or ask a gifted soccer player how he knows where the ball will be two touches before it arrives, and he likely cannot tell you, but he knows to be at that spot on the pitch anyway. Intimations of things long before we are conscious of them are a common experience in life.

We all know this, but we educators often behave as if we don't. We assume that, and behave as if, knowledge is strictly referential, based solely on our representations, descriptions, images, or mathematical formulations, to use Nicolescu's list. Knowledge is something we can put on the test next Tuesday. It isn't (you'll get a much better discussion of the issues with representational views of knowledge from Stephen Downes' blog Half an Hour). Knowledge extends beyond conscious knowledge.

But is this extended view of knowledge useful to education? I think it is extremely useful for those who envision education as a complex process of traversing networks—not as a walk to be taken (traced), but as a walking (mapping). I'm playing here with ideas that I've gleaned from Morin and Deleuze and Guattari.  Morin's concept of interdisciplinary research suggests that the path to knowledge is not followed, it is forged. He amplifies this idea with a line I've often quoted in this blog: we must learn to define from the inside out, not from the outside in. Deleuze and Guattari suggest that engagement of the rhizome, the Real, is a process of mapping structures and pathways, not tracing given structures and pathways. To my mind, these ideas position the Knower at the center of the zone of engagement as a knowmad who chooses to engage some aspect of the rhizome. Or not.

This tack positions me with the knowmad and suggests questions about what prompts a knowmad to engage or disengage some aspect of the rhizome. This reverses the usual pedagogical question of how to motivate students, as if motivation is a trigger we can pull, a response we can stimulate. I'm not sure it is. What then prompts a student to engage a teacher, a given curriculum, and a class? Where does this come from? And is there anything a teacher can do to facilitate that engagement?

Let's ask from the knowmad's point of view: why would a twenty-year-old studying to be a physical therapist want to engage a sixty-year-old in a course about writing? Why would they want to avoid such an engagement? In his book The Art of Changing the Brain (2002), James Zull says that most students unconsciously decide within the first 30 seconds of entering a class whether or not they will like it. Or like me. I probably know within the first 30 seconds whether or not I will like a particular class. These largely emotional engagements with the Real set the parameters of the Reality of the class, and they are difficult to change, in large part because we never quite make them conscious, or explicit. We just have a feeling that some classes work and some don't. However, some very heavy, precise neurological sensing and cognitive processing has gone on underneath the conscious surface to cause this particular Reality to emerge in the zone of engagement I and my students call Composition 1. Peering into the collective unconscious of the class to determine why a class is not working is more work than most of us care to take on, but it is extremely important for the success of the class.

There are plenty more questions to ask from the view of the knowmad: does this twenty-year-old have any sense of where I want to take them in the class? And do they want to go there? Do they have any hope of success? Any desire for success? Does this connect in any way with the path they are already on, or is this a side-trek they had just as soon avoid? And mostly: do they really want to connect to this sixty-year-old, short, white guy with his corny jokes told in a slightly southern accent?

The willingness to engage always comes from the knowmad themselves. The knowmad must see some path worth traversing, because mapping the rhizome is hard work. And it is the rare knowmad, especially young knowmads, who know why they want to engage or not. Much of our willingness to engage or not with a particular aspect of the rhizome, the Real, is decided prior to or completely outside of consciousness. As educators, we overlook this unconscious aspect of reality at our peril.

Quantum Random Walks and MOOCs

If Reality is an emergent property of the zone of engagement between the Knower and the Real, then what does that say about education in general and educational practices such as MOOCs in particular?

I think I should draw out some of the implications of this arrangement: a zone of engagement between the Knower and the Real. Most of the Real is hidden from us, both because it is beyond the horizons of possible engagement and because there is more Real than we can engage even within those horizons. Still, there is plenty of Real that we can know (we won't run out), and we are ever extending our horizons through technologies that allow us to engage more and more. So there's lots to learn, even if we can never learn it all. That's extremely good news, I think. A fine gospel for educators. Our vocations, if not our jobs, are secure.

That's our status in terms of the Real, but what about Reality, or the stuff that we can engage and can know, the stuff that "resists our experiences, representations, descriptions, images, or mathematical formulations" (Manifesto, 20)? Do we know all of that? This seems to me a tricky question. The first glib answer is that, of course, we don't know all of Reality, but I immediately want to counter that while I or you alone don't know all of Reality, maybe we do. Is it useful to define Reality as the sum total of what humans know and have known? I think so, and I think it points us to a most useful feature of MOOCs.

It seems to me that MOOCs, especially of the Connectivist variety, help us to approach the question of what we know rather than what I know. This is an important question because it undermines traditional education and its strict grading economy: 1 student = 1 grade, no cheating.

As electronically networked entities, MOOCs function similarly to quantum walks, a concept I first heard about in MIT quantum computing engineer Seth Lloyd's talk on Quantum Life, or how organisms have evolved to make use of quantum effects. At one point (11:50), Lloyd asks how photosynthesis can be so efficient (about 99%) when a photon that strikes a leaf must go through a maze of molecules to find the central photosynthesis processing unit. Apparently the photon engages in some very special kind of quantum multi-tasking, or quantum superposition, called a quantum algorithm. I don't have the science and mathematical knowledge to go into the details, and as Lloyd notes himself, even quantum scientists find superposition counter-intuitive, but basically the photon is able to explore all pathways at once, quickly locating the correct path to bliss.

For me, a better, more manageable, image of quantum walks is how bees search for a new hive. The bees start from the hive and then search all paths (approximately) at once, bringing back reports about each path, which is subsequently processed by the hive. This is what MOOCs can do, and this is what makes them so powerful, at least for me. Like bees searching for a new hive, MOOCers can begin in the middle with a given curriculum, but then they fan outward making a thousand different connections at once before bringing that new information back to the MOOC. Rather than exploring the single path of a single instructor, a functioning Connectivist MOOC explores nearly all paths at once, making connections to more knowledge, more contexts, than any single instructor, even a really bright and gifted instructor, can make. In other words, like bees in a hive, MOOCs use a process something like a quantum random walk to search all paths (approximately) at once, aggregate that knowledge with something like GRSShopper, and thereby create actionable knowledge available to the entire MOOC.

I like this image. For me, it captures some of the best of what happens within a successful Connectivist MOOC. This is good stuff.

Reality as a Zone of Engagement

So I've distinguished the Real from Reality and accepted that most of the Real is hidden, probably forever and not just from me but from my entire species, both because we physically cannot encounter it all and because, even if we could, we can't hold it all. Hmm … perhaps. This last point troubles me. I accept that I cannot hold it all, but what about we? Can we hold it all? Perhaps not, but we can certainly hold much more knowledge than I alone, and that may be sufficient for whatever tasks our species encounters. This is a thought that I will keep. Hold that thought.

At any rate, I now have the Real, Reality, and Knowledge. If I understand Nicolescu, Reality is the zone of engagement between the Real and the knower. Nicolescu describes this zone in, for me, rather interesting terms:
By "Reality" (with a capital R) we intend first of all to designate that which resists our experiences, representations, descriptions, images, or mathematical formulations.
Reality, then, is first that zone within the Real that in some way resists my pushes outward. Reality is the stuff I can bump into, the stuff that I can draw or sculpt or construct, the stuff that I can describe in words or mathematical formulations. Reality is the stuff that sends back a signal when I ping it. Group knowledge, I suppose then, is that zone within the Real that pushes back in similar enough ways when any of a group of us ping it.

I'm immediately troubled by my knowledge of those things—say, the Greek gods or Yoda—that I can push against and describe, but that I don't want to admit into the realm of Reality—and certainly not the Real—but let's not think about that for the moment. What I like about this description of Reality is the dynamic process of engagement between the Real and the knower, or between ontology and epistemology. Reality, I think, is first an emergent property of the interaction between my push outward and whatever pushes back. Of course, sometimes the Real pushes in first and I push back in response. In other words, reality as a zone of engagement is a reciprocal process, but the key is the dynamic interaction, the zone of engagement, out of which Reality emerges.

And here is the key for me in answering my original question: does epistemology take second seat to ontology? Perhaps it should; however, the moment-to-moment emergence of Reality within the interactions of the Real and the Knower seems to depend as much on the Knower (epistemology) as on the Real (ontology). I'm quite certain that Reality—the stuff that I know of the Real—depends as much, if not more, on my engagement with the Real and the processes by which I make sense of that engagement. In his wonderful book The Master and his Emissary (2012), psychiatrist and literary scholar (cool) Iain McGilchrist explores the two realities created by our divided brains, and he is quite explicit about the role we play in creating Reality:
In fact I believe there is something that exists apart from ourselves, but that we play a vital part in bringing it into being. A central theme of this book is the importance of our disposition towards the world and one another, as being fundamental in grounding what it is that we come to have a relationship with, rather than the other way round. The kind of attention we pay actually alters the world: we are, literally, partners in creation.
When I connect McGilchrist's book to Zull's book about the neuroscience of learning, it seems highly likely that my and our Reality depends as much on my/our neurological apparatuses and processes as it does on the ontological features of the Real.

However, I think, too, that the Real as well as Reality is changed by engaging with the Knower. If I understand my readings in quantum physics correctly, then many physicists accept that engaging the Real changes all parties of the engagement, the Knower/s as well as the Real itself. This seems counter-intuitive in day-to-day life. For instance, most of us assume that our car remains the same thing ontologically whether we are looking at it or not and regardless of the angle from which we look at it, but quantum physics seems to suggest that this is not so. While fine quantum weirdnesses are often flattened out in the coarse structures and processes of everyday life, this is not always so. In his Big Ideas talk The World as a Hologram (2011), quantum physicist Leonard Susskind tells the story of two friends Alice and Bob and what they both experience when Alice falls into a black hole. From Alice's point of view, nothing happens as she crosses the point of no return where she can no longer resist the inexorable pull of the black hole. However, from Bob's point of view, Alice is incinerated in a flash of unbelievable heat and disappears forever. In one reality, then, Alice is fine, but in the other reality, Alice is dead. At the same time. This makes no sense, but here's a serious, world-famous scientist insisting that it is the case.

So I don't think that epistemology quite plays second fiddle to ontology. I am increasingly coming to believe that the interactions across the zone of engagement between me and the Real not only change me, but they also change the Real. Engagement changes all parties to the engagement, and the Realities that emerge from that engagement depend very much on the relative positions of the engaged parties.

So what does this have to do with MOOCs and quantum random walks? Much it would seem.
