"Schools as Knowledge Building Organizations"

Scardamalia has noted that educators tend to think students need to know all the facts and findings of a discipline before they can start building knowledge in that field. So, for example, first students must know what atoms are, what protons and electrons are, must know about the distribution of charges and how things attract and repel, what a metallic bond is versus a covalent bond, must be told all of these facts, before they can begin to build knowledge about, say, conductors and insulators. Taking issue with this, she notes:

"...What makes work 'scientific' is a matter of continuing controversy and is not a matter to be settled here; but we may at least agree that science is a form of social practice that goes on, with wide variations, in groups recognized as scientific...We see school-age students as ... having about 500 years of science to catch up on... They can begin functioning as real scientists as soon as they are able to engage in a form of social practice that is authentically scientific, one that is concerned with the solution of recognizably scientific problems in recognizably scientific ways."

APA Learner-Centered Psychological Principles

From the American Psychological Association, a collection/distillation of ed psych type findings on principles for learning. The document began when GHW Bush was pushing for more accountability in education and members of the APA began wondering:

How can we bring to the attention of the public, educators and policy makers what we know about learning [and] what we know about motivation that can influence some of these decisions that may be well intended but certainly weren’t going in a direction that many of us felt as people who understood learning and motivation would be for the good of children? (from McCombs at ICLS).

These principles are deliberately not discipline-specific. But they're interesting-- and the wording ("successful learners do X", rather than "successful learning environments have Y") is worth thinking about. As is the first point, "The learning of complex subject matter...".-- I think that understanding complex subject matter is an outcome of "active, goal-directed, and self-regulated" engagement with ideas. When we focus exclusively on learning as "learning complex subject matter" -- instead of learning as adopting certain habits of mind/appropriating tools of disciplines (in particular discursive practices)-- we can't help but fall back into assessments that assess whether or not students "know" complex subject matter.

Clark and Shaefer

Clark and Shaefer's 1989 paper on grounding.

I've been looking into the role that analogies play in scientific discourse-- trying to distinguish the interactive, dialogic role of analogies from the more cognitive, logical problem-solving role that characterizes much of the research on analogical reasoning.

Clark and Shaefer's work on grounding in discourse is a possible direction for understanding analogies:

When people take part in a conversation, they bring with them a certain amount of baggage— prior beliefs, assumptions and other information. Part of that baggage is their common ground, which Stalnaker (1978) described this way: “roughly speaking, the presuppositions whose truth he takes for granted as part of the background of the conversation… Presuppositions are what is taken by the speaker to be the common ground of the participants in the conversation, what is treated as their common knowledge or mutual knowledge.” (p. 320, original emphases)… in actual conversations, the presuppositions vary from one participant to the next, though usually not too drastically. (p 260 of C & S)

Analogies can perhaps be understood as a move to establish common ground-- choosing a domain in which the participants can agree on all the presuppositions regarding the structure of the domain and the kinds of ontologies involved. Of course, the participants might disagree on the appropriateness of the analogy (might be a kind of structure-mapping move as this happens). Most of the analogies in my corpus (of spontaneously generated analogies in science discourse) are not used to map but to ground.-- Once the analogy is agreed on as appropriate, it has served its purpose and is no longer used.

From the 2006 ICLS

Major talks from the 2006 International Conference of the Learning Sciences are available online.

Some highlights and quotes from "The Learning Sciences and the Future of Education:"

from Allan Collins: "Education is seeping out of schools"-- we're moving from "just in case" education to "just in time" education.

from Jere Confrey: "It's not just knowing but letting know."

from Janet Kolodner: "Learning is not just about content: it needs to focus on 'becoming'—helping people to grow in capabilities and awareness and disposition (which includes learing content)."

from Marlene Scardamalia: "What would an education look like where we actually thought about innovation from the beginning with learning as a by-product of continual and creative work with ideas?"

How would we define a discipline- a physics class, say- if the content is a by-product of engagement with ideas? Would it have to focus on discipline-specific ways of asking and answering rather than the topic of investigation?

Following their talks, some ideas in the following conversations:

Allan Collins: "The Learning Sciences and NSF have spent a lot of money to invest in developing curricula and learning environments. At the same time we’ve seen this huge increase on accountability, and the testing methodology is tied to every kid learning the same things at the same time and it’s fundamentally incompatible with the kinds of power that the learning environments we’ve been developing enable. We want kids to pursue things deeply that they care about. And the technologies make that possible- you can break the lock-step schooling with these powerful technology environments. But if the tests we’re using to evaluate kids depend on a lock-step system, then all the technology we build is going to go nowhere.

The second thing I want to say is: that’s one deep incompatibility between what real school as we understand it is and what technology empowers. Technology empowers kids taking control of their education. It empowers learning what you’re most- I mean, this personalization this customization it lets kids learn what’s important to them. And if we ignore the imparities (?) of technology as we design education systems, we’re not going to go anywhere. So I think we’re going to need to understand what technology does well and understand that that’s incompatible with the ways that people understand what schools do. And because of that incompatibility a lot of education is going to be taking place outside of schools. And so we need to begin to think about how we can use the affordances of technology and the changing environment to make our educational systems work in new venues."

It seems to me that this goes far beyond technology. Authentic scientific discourse, inquiry, discovery teaching-- all empower these same things that Collins claims to be a strength of technology. I'd rather see schools change to match our understanding of what education can be than see our educational technologies and experiences taken out of schools.

This resonates with findings from a RAND study on the effectiveness of reform science instruction: "It is also important to note the influence of high-stakes accountability testing on teaching practices. Teachers reported that the testing environment influenced their use of reform-oriented practices despite the training they had received. In particular, many teachers believed that the reform-oriented practices were likely to be less effective than other kinds of practices for promoting high scores on state accountability tests. Future research on the effectiveness of reform-oriented instruction needs to recognize that instructional reforms are not carried out in a vacuum, and it should examine the broader contextual factors as well as the specific elements of the intervention." (p. xviii - xix)

It also suggests that having specific content goals in a classroom is necessarily inconsistent with reform instruction.

From Jere Confrey, in response to a question on diagnostic, as opposed to traditional high stakes testing:

"Three things that go into courts- and I read a number of the court cases- the three things that they talk about in testing are: reliability, validity, fairness. The only thing that ends up (practically) in the courtroom is reliability because it has a formula attached therefore it can be disputed....We don’t debate in the courts issues of validity and we have very poor understanding how to talk about fairness with regard to legal and court practices. Sure let’s have these other methods [low-stakes/diagnostic tests]. But the high stakes tests have got to be a target for us because it’s driving so much of what’s happening in the schools and we have to go after- from the perspective of our field- what it means to define and measure and take to the court-level issues of validity and issues of fairness in a way that will drive the system in directions we’re comfortable with."

A question is asked about the structure of the discipline being lost in "just in time" education.

Allan Collins: "My general argument is: I am not an advocate for what is happening. I’m not saying we’re moving towards a halcyon environment with this revolution. Downsides also relate to equity, citizenship, and you make one I hadn’t thought about previously. That’s a serious problem. Now it is the case that as you learn in a workplace or an adult education center, you may in fact go deeply into some subject area, such as the history of the American nation. And you may get an understanding of the structure of that discipline. But as we’re designing an environment we need to think about this issue of the structure of knowledge and we need to understand that those environments...we need to be thinking how to make this transition because it’s happening. We need to think seriously from a broad educational system point of view how to make that transition."
