» Intrusive Scaffolding, Obstructed Learning (and MOOCs) SAMPLE REALITY
"If you think of riding a bike in terms of pedagogy, training wheels are what learning experts call scaffolding. Way back in 1991, Allan Collins, John Seely Brown, and Ann Holum wrote about a type of teaching called cognitive apprenticeship, and they used the term scaffolding to describe “the support the master gives apprentices in carrying out a task. This can range from doing almost the entire task for them to giving occasional hints as to what to do next.” As the student—the apprentice—becomes more competent, the teacher—the master—gradually backs away, in effect removing the scaffolding. It’s a process Collins, Brown, and Holum call “fading.” The problem with training wheels, then, is that fading is all but impossible. You either have training wheels, or you don’t.

Training wheels are a kind of scaffolding. But they are intrusive scaffolding, obstructive scaffolding. These bulky metal add-ons get in the way quite literally, but they also interfere pedagogically. Riding a bike with training wheels prepares a child for nothing more than riding a bike—with training wheels.

My oldest child, I said, learned how to ride a bike with training wheels. But that’s not exactly what happened. After weeks of struggle—and mounting frustration—he learned. But only because I removed the all-or-nothing training wheels and replaced them with his own body. I not only removed the training wheels from his bike, but I removed the pedals themselves. In essence, I made a balance bike out of a conventional bike. Only then did he learn to balance, the most fundamental aspect of bike-riding. I learned something too: when my younger son was ready to ride a bike we would skip the training wheels entirely.

My kids’ differing experiences lead me to believe that we place too much value on scaffolding, or at least, on the wrong kind of scaffolding. And now I’m not talking simply about riding bikes. I’m thinking of my own university classroom—and beyond, to online learning. We insist upon intrusive scaffolding. We are so concerned about students not learning that we surround the learning problem with scaffolding. In the process we obscure what we had hoped to reveal. Like relying on training wheels, we create complicated interfaces to experiences rather than simplifying the experiences themselves. Just as the balance bike simplifies the experience of bike riding, stripping it down to its core processes, we need to winnow down overly complex learning activities.

We could call this removal of intrusive scaffolding something like “unscaffolding” or “descaffolding.” In either case, the idea is that we take away structure instead of adding to it. And perhaps more importantly, the descaffolding reinstates the body itself as the site—and means of—learning. Scaffolding not only obstructs learning, it turns learning into an abstraction, something that happens externally. The more scaffolding there is, the less embodied the learning will be. Take away the intrusive scaffolding, and like my son on his balance bike, the learner begins to use what he or she had all along, a physical body.

I’ve been thinking about embodied pedagogy lately in relation to MOOCs—massive open online courses. In the worse cases, MOOCs are essentially nothing but scaffolding. A typical Coursera course will include video lectures for each lesson, an online quiz, and a discussion board. All scaffolding. In a MOOC, where are the bodies? And what is the MOOC equivalent of a balance bike? I want to suggest that unless online teaching—and classroom teaching as well—begins to first, unscaffold learning problems and second, rediscover embodied pedagogy, we will obstruct learning rather than foster it. We will push students away from authentic learning experiences rather than draw them toward such experiences.

After all, remember the etymological root of pedagogy: paedo, as in child, and agogic, as in leading or guiding. Teachers guide learners. Scaffolding—the wrong kind—obstructs learning."
