Skepticism Improves Innovation

Greg Ashman is enthusiastic about research, and yet skeptical about innovation.

Ashman’s argument resonates with me in large measure because it helps explain the power of Mind, Brain, Education as an approach to teaching.

Of course, MBE does offer its own specific pedagogical suggestions. For example: if you’ve spent any time at Learning and the Brain conferences, you know the benefits of active recall. (Both Ian Kelleher and Scott MacClintic have blogged on this topic recently.)

The Bigger Picture

More broadly, MBE gives teachers a consistent rubric with which we can measure the value of many other pedagogical approaches. Here’s what I mean:

Is project based learning a good idea? How about flipped classrooms? Service learning? 1-to-1 laptop programs? Design thinking?  Or, the new idea that will inevitably surface tomorrow?

If you’re being encouraged to try one of these approaches, it can be hard to know how to measure its effectiveness. All of them have research (of some kind or another) showing how beneficial they are. All of them have enthusiastic endorsements by earnest-seeming teachers. All of them have books and conferences and websites and … I don’t know … Ben & Jerry’s flavors named after them.

But: do they all work? How can they – some seem to conflict with each other.

The more you know about MBE, however, the more tools you have that allow you to make consistent comparisons.

Here’s what I mean…

The First Tool in the Toolbox

If you’ve learned about working memory at an LaTB conference, then you already know it is a short-term memory capacity that allows people to hold several pieces of information, and then reorganize and combine them into some new pattern.

For example: if I ask you to put the 6 New England states into alphabetical order, you have to hold all six names in your memory, and then reorganize them in a particular way. That’s working memory.

You may also know that working memory is very small; you can probably alphabetize 6 states, but you couldn’t do sixteen – at least, not without writing them down.

Once you understand even a few simple facts about working memory, then you can use that MBE knowledge to analyze all of the pedagogies listed above.

Is project-based learning a good idea? Well: what might it do to working memory?

Do 1-to-1 laptop programs increase or reduce working memory demands?

In other words: now you have a consistent criterion – one you can use to analyze all new proposals that come across your doorstep.

More Where That Came From

Michael Posner’s work on attention provides an equally useful yardstick. It might tell you, for example, whether flipped classrooms are likely to enhance or diffuse attention. (Or, more likely, both…)

So too Carol Dweck’s work on mindset, and Claude Steele’s work on stereotype threat. And Mary-Helen Immordino-Yang’s work on emotion.

And so: MBE allows you both to learn about specific psychology- and neuroscience-based teaching strategies and to develop a system for measuring all the other pedagogical proposals that crowd your inbox.

As Ashman implies: research helps us not only because it allows innovation, but also because allows consistent, skeptical analysis of innovation. Our students will benefit from both.

 

More Brain Horsepower?

This article summarizes the current debate — call it a “controversy” — about brain training. (The authors prefer the phrase “cognitive training.”)

The authors conclude that intelligence can be increased, but … so far … only in controlled lab settings. That is: NOT in schools with various training programs…

This article does get a bit technical; for instance, the authors debate whether or not a particular series of studies ought to have been included in Melby-Lervag’s & Hulme’s well-known meta-analysis. (Melby-Lervag & Hulmedid not include the studies, and these authors think they should have.)

At the same time, I think the complexity of the question is the point. If you or your school plan to devote the considerable time and money that this kind of training requires, you should know all sides of the argument.

(Caveat emptor: this article is, in effect, an advertisement for the authors’ book. I haven’t read that book, but … based on the thoughtful balance of the article … they strike me as sensible folk.)

The Misleading Headline of the Week…and What to Do About It

Scientific American Mind has entitled this brief piece “Too Much Emotional Intelligence is a Bad Thing.”

Given the content of the article — and common sense — a more accurate title would be “In very particular circumstances, the ability to read others’ emotions well might raise cortisol levels for some people while they speak in public.”

That alternate title isn’t as clickable…but, it also doesn’t substantially misstate the point of the research it summarizes.

The Larger Point

Even reputable magazines can overstate researchers’ conclusions — especially in headlines. For this reason, we should always look closely at the particulars of any research paradigm before we make decisions about relying on an article.

For example: if I wanted readers to click on a headline, I might summarize Ina Dobler’s study this way:

“Asking Students to Remember Causes Them to Forget!”

Believe it or not, “retrieval-induced forgetting” is a thing, and — in particular circumstances — might be a problem in classrooms.

(I wrote about retrieval-induced forgetting last year; you can read that article here.)

However, as you know if you’ve attended recent LaTB conferences; or read Scott’s or Ian’s entries on this blog; or read make it stick by Brown, Roediger, & McDaniel; or How We Learn by Benedict Carey, asking students to generate answers to questions is most often a highly beneficial way to help them consolidate memories.

In other words, my headline — by sloppily overgeneralizing Dobler’s conclusions — could badly mislead casual readers.

To quote a recent Scientific American headline: “Overreliance on Magazine Headlines is a Bad Thing…”

Political Affiliation and Trust in Science

Over at the Cultural Cognition Project, Dan Kahan has offered a fascinating post about the relationship between political beliefs and trust in science.

As we all know, party affiliation strongly aligns with beliefs about human causation of climate change. Whereas — according to graphs that Kahan has posted — something like 90% of those who are “very liberal” believe that humans have caused climate change, only 20% of those who are “very conservative” do.

Kahan’s question: does that political skew appear for other questions requiring scientific expertise?

The answer: NO.

For instance, liberals, moderates, and conservatives are all more than 75% confident that the benefits of vaccines outweigh the risks, and have confidence in the public health officials who make these decisions.

In another graph, Kahan shows that both liberals and conservatives hold the scientific community in very high regard. For liberals, it ranks #1 for institutional confidence ratings (above medicine, the military, and the Supreme Court…and way above television); for conservatives, it ranks #2 (behind the military, above medicine and the Supreme Court…and way above the press).

For teachers who want to use scientific data to inform teaching practice, Kahan’s post may well come as a great relief. If you’ve been worrying that your reliance on research might sound like a kind of political affiliation, you can rest easier knowing that most of us — liberals, moderates, conservatives — have a high degree confidence in scientists.

 

Book Review: the Promise and Perils of fMRI

Russell Poldrack reviews Sex, Lies, and Brain Scans: How fMRI Reveals What Really Goes on in our Minds, by Barbara J. Sahakian and Julia Gottwald.

As Poldrack emphasizes, it’s falling-off-a-log easy to overestimate the power of fMRI: in fields such as lie-detection and neuro-prediction, we regularly see hype and misunderstanding rather than sober and substantial understanding.

My favorite line from the review: “[N]euroimaging is usually only as solid as the behavioural research that underpins it.”

The take-away for teachers: brain images from neuroscience-world are compelling, but we should be sure to have psychology research as well before we make changes in our schools and classrooms.

A Skeptic Meditates

Scott Barry Kaufman meditates — rebelliously — for eight weeks, and learns a lot about himself, mindfulness, anxiety, and creativity…

(One of his provocative conclusions: “Mindfulness is not the opposite of mind-wandering…”)

Does Internet Use “Rewire Adolescent Brains”?
Andrew Watson

Our very own Kathryn Mills says: we’ve got a lot of anecdotes, but not a lot of evidence, suggesting that internet use is meaningfully changing — much less damaging — adolescent brains.

For example: one study that Mills cites tracks 908 adolescents for 2 years, and finds no meaningful correlation between an increase in World Wide Web surfing and a reduction in free time physical activity. In other words: the couch potato stereotype might exist more on TV drama than in reality.

In brief: although our teacherly instincts might warn us that the Web has drastically  changed adolescent cognitive or social abilities, researchers haven’t yet found much evidence to confirm these fears.
