Over the last few weeks I’ve found myself reflecting a lot on how much has changed in the educational landscape and my own thinking since What Readers Really Do came out two and a half years ago. And having also spent some time last month working with Lucy West, Toni Cameron and the amazing team of math coaches that form the Metamorphosis Teaching Learning Communities, I want to share some new thoughts I’ve been having about the whole idea of scaffolding.
From what I could gather from a quick look at (yes, I admit it) Wikipedia, the idea of scaffolding goes back to the late 1950′s when the cognitive psychologist Jerome Bruner used it to describe young children’s language acquisition. And by the 1970′s Bruner’s idea of scaffolding became connected with Vygotsky’s concept of a child’s zone of proximal development and the idea that “what the child is able to do in collaboration today he will be able to do independently tomorrow.”
Even before the Common Core Standards, teachers have been encouraged to scaffold by using scaffolding moves like those listed below (which were culled from several websites):
- Activating students’ prior knowledge
- Introducing a text through a short summary or synopsis
- Previewing a text through a picture walk
- Teaching key vocabulary terms before reading
- Creating a context for a text by filling in the gaps in students’ background knowledge
- Offering a motivational context (such as visuals) to pique students interest or curiosity in the subject at hand
- Breaking a complex task into easier, more “doable” steps to facilitate students achievement
- Modeling the thought process of students through a think aloud
- Offering hints or partial solutions to problems
- Asking questions while reading to encourage deeper investigation of concepts
- Modeling an activity for the students before they’re asked to complete the same or similar one
As I looked at in last year’s post on Common Core-aligned packaged programs, scaffolding these days has been ratcheted up even more, with teachers more or less being asked to do almost anything (including doing a think-aloud that virtually hands over the desired answer) to, in the words of one program, “guide students to recognize” and “be sure students understand” something specific in the text. And, for me, that raises the question: What is all that scaffolding really helping to erect or construct? Is it a strong, flexible and confident reader who’s able to independently understand all sorts of texts? Or is it a particular understanding of a particular text as demonstrated by some kind of written performance-based task product?
If we think about what’s left standing when the scaffolding is removed, it seems like we’re erecting the latter, not the former—though in What Readers Really Do, Dorothy Barnhouse and I attempted to change that by making a distinction between what we saw as a prompt and a scaffold, which can be seen in this chart from the book:
Most of the scaffolding moves listed above don’t, however, follow this distinction. Many solve the problems for the students and are also intended to lead students to the same conclusion—a.k.a. answer—as the teacher or the program has determined is right. I’m all for reclaiming or rehabilitating words, but given that the Common Core’s Six Shifts in Literacy clearly states that teachers should “provide appropriate and necessary scaffolding” (italics mine) so that students reading below grade level can close read complex texts, redefining the word scaffold may be a bit like Sisyphus trying to push that boulder uphill. So I’ve been thinking (and here’s where the math folks come in) about recasting the kinds of scaffolds Dorothy and I shared in our book as what my math colleagues call models.
Models in math are used not only as a way of solving a problem but of understanding the concepts beneath the math (which Grant Wiggins has just explored in a great “Granted, and. . . ” blog post). Here, for instance, are two models for multiplication: The first is a number line which shows how multiplication can be thought of as particular quantity of another quantity (in this case, three groups of five each), and the second the Box Method, or an open array, shows how large numbers can broken down into more familiar and manageable components and their products then added up. Each model is being used here to solve a particular problem, but each can be immediately transferred and applied to similar problems:
And here’s a text-based Know/Wonder chart that records the thinking of a class of 5th graders as they read the first chapter of Kate DiCamillo’s wonderful The Tiger Rising (and—sneak peak—will be appearing in my next book):
Like the math models, it references the specifics of a particular text, but it’s also a model for solving certain kinds of problems—in this case, how readers figure out what’s going on at the beginning of a complex texts and develop questions they can use as lines of inquiry as they keep reading. In effect, the chart makes visible what those students were “able to do in collaboration” that day that they’ll “be able to do independently tomorrow,” because, whether we call it a scaffold or a model, it’s directly and immediately transferrable to other texts that pose the same problem.
In the end I don’t think it really matters what we call this kind of support, but I do think we have to ask ourselves what, exactly, we’re scaffolding or modeling. Are we helping students get a particular answer to a particular problem or text in order to produce a particular assignment? Or are we, instead, really offering a replicable process of thinking that’s tied to the concepts of a discipline, which can start being transferred tomorrow not an at indeterminate point in the future? Of course, that raises the question of what the underlying concepts in reading are, which we don’t talk about as much as my math colleagues do for math. But that I’ll need to save for another day . . . .
