Just before I read Keefer's post, I came across an Edutopia post by Bob Lenz called Deeper Learning Community of Practice Recap, in which he lists some comments by Kathleen Cushman in response to a recent Deeper Learning meeting. After reviewing some student work from the workshop, Kushman asked "What had the teacher done to scaffold this work in its early stages?" She listed several specific techniques the teachers used:
- They build learning relationships with students.
- They design and plan backward from clear learning objectives.
- They co-construct curriculum with students and colleagues.
- They use inquiry to drive instruction.
- They scaffold student learning.
- They assess continuously.
- They reflect on their own and others' work.
- They use protocols to engage in collegial critique.
This seems like a pretty good collection of techniques to me, and I use most of them at one time or another, but from which learning theory do these techniques naturally follow? Hmm … seems to me that most any theory could lead to all or part of this collection of classroom activities. Could you use one of these techniques with no particular theory in mind? I could. I suspect most teachers do.
Okay, if you could do all these things in a classroom without a learning theory, then what good is a learning theory, or even more questionable, what good is a learning metaphor?
I think theories and metaphors provide a more or less systematic and coherent set of lenses for looking at reality. A theory highlights certain elements and processes, bringing them to the foreground, and diminishes the rest of the details, letting them recede into the background. This clarifies the picture for us and gives us a sense of understanding and control.
A theory differs from a metaphor, at least in part, by implying some predictive efficacy. A theory says that if A then B, and then we can test to see if this actually happens. If it doesn't, then we adjust the theory. I don't know that a metaphor is held to the same expectation. I just don't know of a way to test how much love is like a rose or a MOOC is like a rhizome.
Does this mean that metaphors are of no use, then? Not to me. Metaphors are marvelous ways of presenting a gestalt understanding of one thing in terms of another, and our minds are wonderfully attuned to and receptive to this kind of holistic learning. For me then, the image of the rhizome provides a more fertile field within which to develop a more rational, predictive theory such as Connectivism, which in turn leads to new techniques, to a reuse of old techniques, and to MOOCs. The rhizome gives me a marvelously rich and pregnant image with which to engage the MOOC, and here's the main point, we all bring an image to the MOOC. If we bring a less useful image—say, the traditional classroom—then the MOOC does not make sense to us, and we are frustrated by it. If we bring the rhizome image, we are more likely to make sense of what is happening in a MOOC and more likely to engage it productively.
