Duncan: Effective teachers

US Secretary of Education Arne Duncan spoke to the National Education Association today, calling on its members to work with him toward the goal of ensuring that “every child in America is learning from an effective teacher—no matter what it takes.”

That’s a noble goal. In my view, it requires that educators shed their allegiance to theory and adopt effective teaching practices. That’s what it takes.

To be sure, there is a lot of emphasis on high-stakes testing. Mr. Duncan even discussed it as one of the four features of his plan for reforming education. The effective teacher idea is another of the four. High-stakes tests (which need reform of their own, in my view—that’s another post) are only part of the game. Another is using evidence to guide instruction.

But even in the absence of results on high-stakes tests and from pristine research projects, educators can ascertain whether they’re using effective methods. That is, we can devise our own means of ascertaining whether teaching practices are effective at a more micro level. In a lot of ways, the process is relatively simple:

  1. Identify goals and objectives in objectively measurable terms. How will we know if the students have learned X?
  2. Identify the skills and knowledge that students will need to demonstrate mastery of those goals and objectives. What is required to show that a student can competently and independently do X?
  3. Devise teaching algorithms for leading students to acquire the skills and knowledge identified in (ii).
    • Model: Demonstrate the skills for the students or tell them the knowledge;
    • Test: Have the students perform the skill or state the knowledge;
    • Coach: Reinforce and correct their performance;
    • Practice to mastery: Have them perform the skill or repeat the knowledge until they are facile with it and can do it under different, increasingly more challenging conditions.
  4. Assess students’ competence according to the goals and objectives specified in (i).

Sure, I’ve simplified it here. Sure, the goals and objectives would need to be integrated in a fashion consistent with an epistemology of various subject areas. And, you’ll have to cut me a little slack about my use of words such as “tell” and “correct”; telling would need to include providing materials to read, for example. But the idea is just about as simple as I’ve sketched it here.

The area of early reading has been mapped according to this perspective on teaching. We can say how we would recognize a competent reader (i), what the component skills are (ii), and how to teach those skills. But the to-be-learned material doesn’t have to be elementary level reading. If the area is chemistry and the objectives were conducting an experiment using electrophoresis, I think we could perform a similar analysis.

Of course, the real trick will be to get people on board with such thinking. Mr. Duncan seems to want to do something like that, but he’s talking about things at a much grander scale.

Multiple intelligences ain’t

Howard Gardner’s Frames of Mind: The Theory of Multiple Intelligences seems to occupy a special place in the pantheon of education memes. I was reminded of this when I read “Not Every Child Is Secretly a Genius” by Christopher Ferguson. Mr. Ferguson’s essay—it appears in the Chronicle of Higher Education, the news source of record for higher educators—politely explains that sustaining Multiple Intelligences (MI) theory is not a good idea.

Rational analyses of the MI evidence by Dan Willingham and Lynn Waterhouse have shown that there are problems with both the theory itself (e.g., most of the eight intelligences are highly correlated, meaning that they are likely measuring the same “thing” for the most part) and its application in education (e.g., methods based on MI do not lead to better outcomes).

Mr. Ferguson’s essay continues in that same tradition. He makes a strong case for his conclusion that “Gardner’s theory of multiple intelligences was a great idea and worth investigating. It’s just not panning out.”

One best way?

The current Bogus Bowl (it’s number 5) raised questions about the professorate, with one alternative mentioning the belief that there is no one best way to teach. The answer to the question, “Is there one best way to teach?,” is surely, “No.” There are actually something like, oh, a few million ways to teach. But some of them are better than others.

Better? Yes, better. That is, some ways of teaching lead to students who score higher on trustworthy measures of declarative and procedural knowledge than the students taught using some other ways of teaching. [Some people will complain that (a) declarative and procedural knowledge are not appropriate foci for education or (b) that trustworthy measurement is impossible; those are arguments for another discussion.] Of course, Teach Effectively is about identifying and employing, and preparing others to employ those methods that meet this standard.

Fortunately, TE is not alone in the quest for use of evidence-based education. Here’s a resource that some readers will find useful. It’s from the IllinoisLoop, a source that’s been over there in the blog roll for much of the tenure of TE.

Is There ONE Best Way to Run a School?

Is there only one way to run a school?

Does rhetoric about “best practices” point to a single “best” way to teach children?

Of course not.

But ed school theorists insist that there is one “best” method. Not only that, they claim that they know exactly what it is!

Consequently, most American schools have moved to that “constructivist” approach and continue to expand its usage further in their classrooms. But mounting evidence calls the whole constructivist framework into question.

The page goes on to integrate a couple of score or a few dozen sources related to the idea in the lead that I’ve reproduced here. There’s plenty of links to good sources. The page would serve admirably as a syllabus for a course on cutting through gobbledygook and identifying clearly reasoned arguments for teaching effectively. Here’s the link. Study hard. There will be quizzes.

Bogus Bowl II

O.K, folks, here’s a second installment in the Bogus Bowl. Bogus Bowl I will close Saturday night (9 Feb 08), so jump over there (click on “polls” in the top navigation element) and vote in the first one if you’ve not done so already. Then come back here and vote on this one…. Or vice versa.

In this one, we’re examing reasons that educators give for shirking what I’ve sometimes called the “instructional obligation.” It’s your chance to consider alternative rationales for not teaching.

Bologna takes a lick

Orac, whom regular readers will recognize from a few earlier posts, has a lengthy-but-informative piece about complementary and alternative medicine (CAM) that I read a day or so ago. In “The infiltration of woo into mainstream academic medicine: The media notices,” Orac explains that he is glad that some news media are recognizing the fluffy nature of some popular medical treatments.

Along with Dr. R.W. and few others, I’ve made a bit of a name for myself in the medical blogosphere by bemoaning the infiltration of non-science- and non-evidence-based medicine into academia. It’s not a particularly popular viewpoint. The prevailing attitude seems to be: Why be so negative? It’s all good. Moreover, with a credulous media eager to publish stories of “healing” and “humanistic” medicine, those of us who remain skeptical of applying unproven and/or untested remedies in an academic setting, thus giving them the imprimatur of academic medicine and the respect associated with it, are easily painted as dinosaurs, unable to get with the plan, unaccepting of the new order of medicine.
