Look Here Not There: The Limits of Psychology

Limits of PsychologyHow much psychology should teachers learn? And, what kind?

We might be tempted to learn as much as possible.

After all, psychologists study minds in action. It’s hard to think of a topic that might interest teachers more.

Teachers spend all day shaping active minds. Why would we leave any of the discipline out?

Look Here Not There

The invaluable Daniel Willingham has typically thoughtful and practical answers to that question.

He starts by dividing the field into 3 chunks:

Empirical Observations

Theories

Epistemic Assumptions

He argues, in effect, that 2 of those 3 chunks don’t really help teachers do our jobs.

We need to know what empirical observations tell us about learning — especially those well-established empirical observations that are consistently applicable to learners and learning. For example: the limitations of working memory, or the difficulties of transfer.

This information can offer teachers essential guidance on the best ways to help our students learn.

If we overwhelm our students’ working memory capacity, for example, learning simply comes to a halt.

The Limits of Psychology

Although these well-established observations — Willingham calls them “Empirical Generalizations” — help teachers, the other two categories really don’t.

In fact, they might distract and mislead us.

At best, they’re likely to overwhelm our own working memory resources.

For instance: psychological theories not only organize lots of empirical observations. They also make as-of-yet untested predictions about what might happen in other circumstances.

That is, in fact, part of the job of a theory.

However, those untested predictions don’t help teachers. Either we’re aware they’re untested, in which case they don’t tell us what to do (or not to do).

Or we’re NOT aware they’re untested, in which case they might prompt us to try unsupported teaching experiments.

And, epistemic assumptions are typically too broad to be useful.

As Willingham argues, the assertion that “learning is social” leads to differing specific recommendations if you’re a behaviorist or a constructivist.

Beyond the Limits of Psychology: Mental Models

Willingham suggests that teachers need fewer theories and more models: representations of the connections between and among all the empirical findings.

For instance: the image accompanying this article is my own model to represent the relationships among working memory, long-term memory, emotion, motivation, and attention.

That image doesn’t attempt to make predictions, as theories do. Instead, it shows that each of these five topics interacts with all of the others. It suggests that working memory stands “between” the experiential world and long-term memory. It emphasizes the overlap between emotion and motivation as concepts.

Its strives, in other words, to help teachers remember key points about these topics, and to understand the connections among them.

(To be clear, this image draws on the work of many previous scholars — including Willingham.)

A Final Note

Although I agree with Willingham’s broad argument, I do think there’s an important exception. As schools increasingly rely on neuroscience and psychology research to inform our practice, we should have an on-site expert in these disciplines.

Although most teachers should indeed focus on empirical findings, we’ll all benefit if at least one of our colleagues has a rich knowledge of the theories and epistemological assumptions that inform and shape those findings.

As you’ve read here so many times before, our reliance on research brings with it a need for informed and curious skepticism.

 

Brains in the Classroom: Research-based Advice for Students

When brain researchers answer our questions, that feels like helpful advice.

However, when they give us unsolicited advice, that can feel like nagging. After all, teachers and students already have plenty of people telling us what to do.

research-based advice for students

This truth puts researchers in a bind. If we are doing something foolish, and they know we’re doing something foolishthey (helpfully) want to give us a warning.

But, if we haven’t asked for that warning, then we’re likely to ignore it. In fact, we might even get angry that we got it.

Research-based Advice for Students: The Problem

This paradox has particular power for researchers who want to advise students.

We’ve got lots of research showing that students use highly inefficient study strategies.

Better said: students use strategies that give them the feeling that they’re making progress right now. Sadly, however, those strategies don’t often result in long-lasting learning.

(This review article by Nick Soderstrom does an excellent job sorting through difference between short-term performance and long-term learning.)

Research-based Advice for Students: A Solution

Three scholars — Miyatsu, Nguyen, and McDaniel — have hit upon a strategy to offer advice without seeming to nag.

Rather than tell students to stop doing what they really want to do, they’ve written an article on using the study strategies students already prefer more effectively.

Other such articles might say: “Stop rereading the text! You’re wasting your time!”

This article prefers an alternate approach: “If you’re going to reread the text, here’s the best way to do it.”

For example: long-time readers of this blog know that rereading the text yields much less learning than retrieval practice.

But: college students LOVE rereading the text. 78% of them use it as a core study strategy.

So, Miyatsu & Co. offer some advice:

Rereading works best for factual material.

Rereading works best when there’s a big gap between the first and second read, AND when there’s a big gap between the second read and the test.

Finally, rereading works best when you use particular strategies to be sure you’re learning from that second read.

See? No nagging!

They also have advice for other key study strategies, including highlighting, outlining, and using flash cards.

Research-based Advice for Students: A Hopeful Prediction

Miyatsu, Nguyen, and McDaniel note that college students rely on study habits formed over years. That is: they …

…appear to hold strong preferences for study techniques that they have used throughout their educational careers; consequently, attempts to sell them on new strategies may be met with resistance.

This note implies that those of us who teach younger students can have a powerful effect by shaping study strategies earlier on.

That is: if we can

inculcate the habit of using retrieval practice;

guide students to choose their study locations well;

help them spread practice out over time;

we can create the (good) study habits that will be hard to break.

In other words: Miyatsu’s article might be immensely helpful right now. However, if we can shape our students’ study habits well, they might not need it when they get to college.

Five years ago, I had lunch with a 13-year-old who was thinking about attending my school.

He spent much of the lunch telling me about string theory. As one does, when one is 13, and obsessed with string theory.

I don’t remember much about string theory, but I do remember this part of the conversation: (more…)
