Meet Blake Harvard, “Effortful Educator”

Read More

Blake Harvard teaches psychology and coaches soccer at James Clemens High School. For three years now, he’s been actively at work trying out teaching strategies derived from cognitive psychology. And, he blogs about his work at The Effortful Educator.

I spoke with Blake about his work, hoping to learn more about the classroom strategies he finds most helpful and effective. (This transcript has been edited for clarity and brevity.) 

Andrew Watson

Blake, thank you for taking the time to chat with me.

I always enjoy reading your blog posts, and learning about your strategies to connect psychology research with the teaching of psychology.

Can you give an example of research you read, and then you tried it out in your classroom? Maybe you tinkered with it along the way?

Blake Harvard

Well, first: retrieval practice and spacing. Research tells us that we forget things very rapidly. Forgetting information and then retrieving that information again strengthens ties in the brain. It promotes long term memory of that information.

So, I’m very conscious of different ways that my students elaborate on information and generate information.

What am I doing to have my kids review? Or, how am I spacing out the information that we were learning yesterday versus what we were learning a week ago versus what we were learning months ago. What are the ties among those things? How are they related?

In the past, when we completed a unit of study, it was in the past. We moved on. Now I’m very careful to revisit. I space out their practice and provide the opportunity for my students to think about material we’ve covered in the past.

And second, dual coding.

I think every teacher does some activity where they have students draw something. But dual coding is more than just about drawing things. It’s about organizing the information: how does it link up?

So, using those general concepts of retrieval practice, space practice, and dual coding, and applying them to my class specifically, I’m constantly trying to get my kids to think – to think more.

Andrew Watson:

Can you give an example of a strategy you use to be sure they do?

Blake Harvard

Sure. One example is, I use an unusual template with multiple-choice questions.

In a normal multiple-choice question, you have a kid read it. They answer “B.” You think, “okay B’s correct, let’s go to the next thing.”

Well, I’ve got this template where kids have to use – have to think about – A through E.

If B’s the right answer, they have to tell me why B’s the right answer. That is, they have to think about B.

But, then, they also have to take A, C, D, and E, and think about those too.

Why is C the wrong answer?

Or, how could you make D into the right answer?

Or, what question could you ask to make E the right answer?

Even, why is A tricky?

Andrew Watson

That seems both simple and extraordinarily powerful at the same time.

Blake Harvard

I don’t want to boil all of cognitive psychology down to that, but that’s really central, I think. There’s no elaborate trick. You don’t need any new technology. At the end of the day, you’re just getting those kids’ brains thinking more with the information.

Andrew Watson

Are there some teaching strategies that you read research about, and you tried them out, and you thought: I understand why this works in psychology lab, but it actually just doesn’t work in my classroom. I’m not gonna do it anymore.

Blake Harvard

Well, I just recently did something with flexible seating. I have an AP psychology student who wanted to try this out in my classroom, I said sure.

I have first block and second block class, and they’re both AP Psychology classes, and they’re both on the same pace, doing the same stuff.

We took the first block class, and we put them in a flexible seating classroom. This classroom had beanbags, it had a couch, it had comfortable chairs, it had only one or two tables with traditional chairs.

With my second block class, we kept them in more traditional seating: sitting at tables, facing the front.

And then I taught a unit, which is about seven or eight days, to both classes. I tried to keep everything the same as much as possible, and at the end we took our unit exam and then we compared the data.

So: how did the seating affect the grades, right?

The people in the flexible seating classroom did worse than the people in the traditional seating.

And then I took the grades and compared them to people who took the same course and the same test in years past. I got the same results. The flexible seating in that one classroom was worse than all of the other classes.

I know it’s not perfect methodology. Nothing is perfect “in the wild,” so to speak. But, I gave it a go. And I’ve decided that that’s not what I want to do.

Now, my student was focused more on the emotional part of it: “how did the kids feel about it?”

She had them fill out a survey: “Do you think you did better?” “Did you feel more comfortable in class?” – those sorts of things. And I haven’t seen those surveys yet; she’s compiling information herself. I am interested to see those too.

I heard some of the comments, and it’s interesting. Some of the comments on the first day of the class that was in the flexible seating classroom were like, “Oh my gosh! This is great!” And then by the end it was, “When is this over?”

Andrew Watson:

I’m wondering if your students take the strategies you use to their other classes? Do they study history with retrieval practice? Or science? Or do you find it stays pretty local to the work you do with them?

Blake Harvard

The short answer is: I don’t know. But I definitely impress upon them that this is how you should be studying.

Rereading your notes is not the most effective way to study. Going back over your notes and highlighting them is not effective. If you’re not thinking about the information, if you’re not actually trying to do something with it, you’re probably not being as effective as you should be.

In fact, it’s not just about simplifying; the right study strategies actually save you time. If you’ve tested yourself on this concept two and three times, and you get the same things right, you’re probably pretty good. You got it. Focus on the other things that you haven’t gotten right.

It doesn’t matter if it’s math, it doesn’t matter if it’s biology, it doesn’t matter what it is. The brain works the way the brain works. If you can’t use the information, if you can’t answer this question, you don’t know it. And you need to study it, because if you did know it, you would have answered the question. It’s as simple as that.

Andrew Watson

Yes. So, we talked about whether or not students use these strategies in other classes. Are there things you encourage them to do that have research support, but they’re particularly resistant to?

Blake Harvard

That’s an interesting question. Nothing off the top of my head is coming to me…

You know: those who don’t think they’re great artists – at first, don’t want to use dual coding. Because they think “my drawing’s bad.” And I’ll say: “you know, it’s not about how good your drawing is. It’s about what it represents to you, in your mind.”

Andrew Watson

The mental practice that goes into it.

Blake Harvard

Exactly. Once you explain that to them, they’re much more receptive to it.

Andrew Watson

One of the tricky parts of our field is that there are many teaching strategies that people say have “a whole lot of research support.” And part of our job is to be good at sifting the good stuff from the not good stuff.

Do you have any advice for teachers who are trying to figure out what really is valid and valuable, not just trending on Twitter?

Blake Harvard

It’s never easy, you know.

Often, I look for multiple cases of a particular teaching strategy. Did they test 20 kids in one classroom? Or was this tested across the country?

You also want to think about the people you have in your class. If researchers test a particular demographic, but you don’t teach that demographic, perhaps their conclusion doesn’t apply to your class. Something that might work in an elementary classroom: there’s a chance it could work in my AP Psychology classroom, but I’ve got to really look at it.

To be fair, this is something I’m figuring out myself.

Andrew Watson

I know that you are a coach as well as a teacher. I wonder if you use any of these strategies in your coaching world as well as your teaching world.

Blake Harvard

Yes, I do, definitely. For me, it has to do with how I structure practice.

I want to show my soccer players what a skill should look like, what the strategy does on the field, why it works.

We want to start small. I want each player individually working on it, and perfecting it or getting better at it. Then we go into a small sided game: maybe two-versus-two or three-versus-three. And then, let’s work it into a bigger scenario.

Eventually, obviously the goal is that they use it in a real-world game.

Just like in the classroom, I’m not a huge fan of inquiry-based learning. I think that there are much more effective ways of teaching than that. I want to explain each new concept to them very clearly, in a very organized way, so that they have a good understanding of what it is. Then we try to apply it to real life. But I don’t start off there.

Andrew Watson

So, you follow the coaching version of direct instruction.

Blake Harvard

Right, yes.

Andrew Watson

Are there questions I ought to have asked you which I haven’t asked you?

Blake Harvard

It’s an interesting journey to get to where I am right now. I graduated with my Master’s Degree in 2006 and up until about 2016 I was just doing just normal professional development: whatever the school had for me to do.

Sometimes I was really excited about it; sometimes I was sitting in there barely paying attention. But now that I’ve found these different types of professional development opportunities, I see they can really improve you, and improve your students and your classroom.

You don’t have to think “I’ll just do the PD that I’m supposed to do and then I go back to my classroom.” There are ways – simple ways, easy ways – to improve your classroom, to improve learning for your students.

Andrew Watson

It’s interesting you say that, because you’ve described my journey as well. I had been a classroom teacher for decades when I found Learning and the Brain, and those conferences completely changed my professional trajectory.

Well, thank you Blake for talking with me today.

Is Failure Productive? (Hint: We Should Ask a Better Question)

Is Failure Productive? (Hint: We Should Ask a Better Question)

Read More

Do students learn better after they experience failure? Two recent studies over at The Science of Learning help us answer that question.

In the first study, professors in a Canadian college wanted to help their Intro Bio students learn difficult concepts more effectively. (Difficult concepts include, for example, the “structural directionality of genetic material.”)

They had one Intro Biology section follow a “Productive Failure” model of pedagogy. It went like this.

First, students wrestled with conceptual problems on these difficult topics.

Second, they got in-class feedback on their solutions.

Third, they heard the professor explain how an expert would think through those topics.

Another Intro Bio section followed these same steps but in a different order:

First, they heard the professor explain how an expert would think .

Second, students wrestled with conceptual problems.

Third, they got in-class feedback on their solutions.

So, all students did the same steps. And, they all followed an “active pedagogy” model. But, one group struggled first, whereas the other group didn’t.

Who Learned More?

This answer proves to be unusually complicated to determine. The researchers had to juggle more variables than usual to come up with a valid answer. (If you want the details, click the link above.)

The headlines are:

On the next major test, students who experienced productive failure learned more.

On the final exam, however, only the “low performing” students did better after productive failure. For the middle- and upper- tier students, both strategies worked equally well.

Conclusion #1:

So, we can’t really conclude that productive failure helps students learn.

Instead, we’re on safer ground to say that – over the longer term – productive failure helps “low performing” students learn (compared to other kinds of active learning).

But Wait, There’s (Much) More

Two weeks after they published the study about Canadian college students in Biology classes, Science of Learning then published a study about German fifth graders learning fractions.

(As we discussed in this post, watching students learn fractions helps researchers measure conceptual updating.)

In particular, these researchers wanted to know if students learned better after they struggle for a while. (Again, for details click the link.)

In this case, the answer was: nope.

So, we arrive at Conclusion #2:

Some college students, but not most, learned more from productive failure in a biology class – compared to those who learned via other active learning strategies.

However, fifth graders did not learn more about fractions – compared to those who learned via direct instruction.

Got that?

The Biggie: Conclusion #3

When teachers come to research-world, we can be tempted to look for grand, once-and-for-all findings.

A particular study shows that – say – students learn better when they use an iPad to study astronomical distances. Therefore, we should equip all our students with iPads.

But, that’s NOT what the study showed. Instead, it showed that a particular group of students studying a particular topic with a particular technology got some benefit – compared to a particular alternate approach.

So, Conclusion #3:

Teachers can often find helpful research on teaching strategies.

We should assume that results vary depending on lots of highly specific conditions. And therefore, we should seek out research that includes students (and classroom subjects) as much like our own as possible.

And so: if you teach biology to college students, you might give the first study a close look to see if its methods fit your students well. (Given that it worked particularly well with struggling students, that variable probably matters to you.)

If, however, you teach fractions to fifth graders, you should probably hold off on productive failure – unless you find several other studies that contradict this one.

In other words: teachers can learn the most from psychology and education research when we investigate narrow and specific questions.

A final thought. I’ve only recently come across the website that published these studies. Congratulations to them for emphasizing the complexity of these research questions by publishing these studies almost simultaneously.

I’m sure it’s tempting to make research look like the last word on a particular topic. Here, they’ve emphasized that boundary conditions matter. Bravo.

The Simplest Motivation Strategy that You’re (Probably) Not Using

The Simplest Motivation Strategy that You’re (Probably) Not Using

Read More

In school as in life, sometimes we just need to get stuff done. And, truthfully, getting stuff done can be a real challenge.

For instance: I’m about to start writing a book. Based on previous book-writing experiences, I can predict the mundane problems that will get in my way.

My cats invariably need attention just as I’m starting to get in the zone.

The alerts from my email account lure me away from difficult writing passages.

I can never decide: stop for a snack now, or wait until lunch?

Luckily, we’ve got a remarkably simple strategy to get over these predictable hurdles.

Give Me Three Steps

Step 1: make a list of the potential problems. (I’ve already done that.)

Step 2: figure out the most plausible solutions.

So, for instance: instead of responding to my email alerts, I can simply close that browser. Problem solved.

Step 3: turn the first two steps into an “if-then” plan.

IF I get an email alert while working on my book, THEN I’ll close my email browser rather than look at the email.

Believe it or not, this simply process makes it much likelier that I will, in fact, ignore the email. (Or the cat, or my hunger.) And, because I’ve taken care of the most common obstacles, I’m much likelier to get my book written.

(Ask me six months from now how it’s going.)

Two More Steps?

This technique is even more effective when combined with another technique called “mental contrasting.”

In a recent article summarizing research in these fields, Marc Hauser describes mental contrasting this way:

In [mental contrasting], the individual first identifies and vividly describes a desired goal or wish. To be effective, this wish has to be feasible, but not easy.

Next, the individual identifies an obstacle that might get in the way of achieving this goal and vividly describes it [too].

Doing both together — vividly describing the goal AND vividly describing the obstacle — turns out to be much more helpful than doing just one or the other.

The Proof in the PSAT, and the Pudding

These techniques seem so simple that it’s hard to believe they work. In fact: why should we believe it?

Well, we’ve got some good research to persuade us. Hauser’s article, in fact, does a very helpful job summarizing both the theoretical background behind these strategies, and the studies that show their effectiveness.

For instance, Angela Duckworth (yes, that Angela Duckworth) worked with high-school students who wanted to prepare for the PSAT. Those who went through this process did 60% more practice problems than those who did a control task instead.

In fact, we’ve got good findings for non-academic tasks as well: limiting drinking, smoking, snacking, and so forth.

Practical Applications for Students

This technique, it seems to me, could be VERY easy for teachers to use. When we talk with our students about their homework habits, we can guide them through this process.

In fact, when I work with students in schools, I bring a specific form to guide them through the process.

(Here’s another approach from Ollie Lovell.)

Equally helpfully, we can use this technique to get our own work under control as well. We might not all have books to write, but we all have plenty of lesson-planning to do.

IF my phone rings while I’m preparing tomorrow’s class, THEN I’ll switch the phone to airplane mode without looking at the caller ID.

Problem solved!

The Better Choice: Open- or Closed-Book Quizzes

The Better Choice: Open- or Closed-Book Quizzes

Read More

Psychology research offers lots of big ideas for improving student learning: self-determination theory, or the spacing effect, or cognitive load theory.

Once we make sense of that research, we teachers work to translate those big idea to practical classroom strategies.

In some cases, we can simply do what the researcher did. In most cases, however, we have to adapt their test paradigm to our specific classroom world.

So, for example, Nate Kornell explored the spacing effect with flashcards. He found that 1 deck of 20 cards produced more learning 4 decks of 5 cards. Why: a deck with 20 cards spaces practice out more than a deck with five cards.

That “big idea” gives teachers a direction to go.

But: we should not conclude that 20 is always the right number. Instead, we should adapt the concept to our circumstances. 20 flashcards might be WAY TOO MANY for 1st graders. Or, if the concepts on the cards are quite simple, that might be too few for college students studing vocabulary.

Translating Retrieval Practice

We know from many (many) studies that retrieval practice boosts learning.

In brief, as summarized by researcher Pooja Agarwal, we want students to pull ideas out of their brains, not put them back in.

So, students who study by rereading their notes don’t learn much; that’s putting ideas back in. Instead, they should quiz themselves on their notes; that’s pulling ideas out.

This big idea makes lots of sense. But, what exactly does that look like in our classrooms?

Over the years, teachers and researchers have developed lots of suggestions. (You can check out Dr. Agarwal’s site here for ideas.)

Thinking about retrieval practice, researchers in Germany asked a helpful question. In theory, closed-book quizzes ought to generate more learning than open-book quizzes.

After all: if my book is closed, I have to pull the information out of my brain. That’s retrieval practice.

If my book is open, I’m much likelier simply to look around until I find the right answer. That’s not retrieval practice.

These researchers wanted to know: does this sensible prediction come true?

The Results Please

Sure enough, closed-book quizzes do produce more learning. This research team retested students on information twice: one week after, and eight weeks after, they heard information in a lecture.

Sure enough, the students who took closed-book quizzes did substantially better than those who took open-book quizzes. (The cohen’s d values were above 0.80.)

In brief: we now have one more research-supported strategy for creating retrieval practice.

As always, I think we should be careful to think about limits on such research.

In the first place, this study took place with college students. If you teach younger students, and your experience tells you that an open-book strategy will work better under particular circumstances, you might ask a trusted colleague for a second opinion. Research like this gives us excellent guidance, but it can’t answer all questions.

In the second place, other variables might come strongly into play. For instance: stress. If your school culture has always allowed open-book quizzes, your students might freak out at the prospect of a closed-book alternative. If so, the benefits of retrieval practice might be lost to anxiety overload.

In this case, you’ll need to take the time to explain your reasoning, and to ease your students into new learning habits.

In any case, we can be increasingly confident that many varieties of retrieval practice produce the desirable difficulties that help students learn. (For a fun exception to this rule, click here.)

 

Studying Wrong Answers Helps Learn the Right Ones

Studying Wrong Answers Helps Learn the Right Ones

Read More

With teaching as with baking, sometimes you should follow steps in a very particular order. If you don’t do this, and then that, and then the other, you don’t get the best results.

Two researchers in Germany wanted to know if, and when, and how, students should study incorrect answers.

To explore this question, they worked with 5th graders learning about fractions. Specifically, they taught a lesson about comparing fractions with different denominators.

(When studying this topic, students can’t rely on their instincts about whole numbers. For that reason, it’s a good subject to understand how students update conceptual models.)

They followed three different recipes.

One group of 5th graders saw only correct answers.

A second group saw both correct and incorrect answers.

A third group saw correct and incorrect answers, and were specifically instructed to compare correct and incorrect ones.

Which recipe produced the best results?

The Judges Have Made Their Decision

As the researchers predicted, the third group learned the most. That is: they made the most progress in updating their conceptual models.

In fact: the group prompted to compare right and wrong answers learned more than the group that saw only the right answers. AND they learned more than the group that saw (but were not prompted to compare) right and wrong answers.

In other words: the recipe is very specific. For this technique to work, students should first get both kinds of information, and second be instructed to compare them.

Important Context

I’ve held off on mentioning an important part of this research: it comes in the context of problem-based learning.  Before these 5th graders got these three kinds of feedback, they first wrestled with some fraction problems on their own.

In fact, those problems had been specifically designed to go well beyond the students’ mathematical understanding.

The goal of this strategy: to make students curious about the real-world benefits of learning about fractions with different denominators in the first place.

If they want to know the answer, and can’t figure it out on their own, presumably they’ll be more curious about learning when they start seeing all those correct (and incorrect) answers.

As we’ve discussed before, debates about direct instruction and problem-based learning (or inquiry learning) often turn heated.

Advocates of both methods can point to successes in “their own” pedagogy, and failures in the “opposing” method.

My own inclination: teachers should focus the on relevant specifics. 

In the link above, for example, one study shows that PBL helps 8th graders think about deep structures of ratio. And, another study shows that it doesn’t help 4th graders understand potential and kinetic energy.

These German researchers add another important twist: giving the right kind of instruction and feedback after the inquiry phase might also influence the lesson’s success.

Rather than conclude one method always works and the other never does, we should ask: which approach best helps my particular students learn this particular lesson? And: how can I execute that approach most effectively?

By keeping our focus narrow and specific, we can stay out of the heated debates that ask us to take sides.

And: we can help our students learn more.

How Can We Encourage Girls to Pursue STEM Disciplines?

How Can We Encourage Girls to Pursue STEM Disciplines?

Read More

When we see alarming statistics about gender disparities in STEM disciplines, we quite naturally wonder how to fix this imbalance.

(This hope – by the way – isn’t simply a do-goody desire to sing “It’s a Small World After All.” If we believe that men and women can contribute equally to a scientific understanding of our world, then every girl discouraged is a contribution lost.

In other words: we ALL benefit if boys and girls contribute to science.)

So, how can we encourage girls to participate in science?

To answer this question, we might first answer a related question: what discourages girls in the first place.

If we can undo the discouragement, we are – indirectly but effectively – encouraging.

So, what discourages girls?

Is Science Education Itself the Problem?

Here’s a disturbing possibility.

When students learn about genetics, and specifically about the genetics of sex differences, they might infer that genders have a fixed, absolute quality. All boys (and no girls) are this way; all girls (and no boys) are that way.

It’s in the genes, see?

This set of beliefs, in turn, might reinforce a fixed mindset about gender and ability.

Through this causal chain, a particular science curriculum might itself discourage girls from pursuing science.

Yikes!

Researcher Brian Donovan and his team explored this question in a recent study. To do so, they asked students to read different lessons about genes and sexual dimorphism.

Some 8th – 10th graders learned about the genetics of human sexual difference.

Others learned about the genetics of plant sexual differences.

Others read a curriculum that explicitly contradicted the notion that genetic sex differences directly cause differences in intelligence and academic ability.

Did these curricular differences have an effect?

The Results Envelope Please

Unsurprisingly, students who learned that we can’t draw a straight line from genes to gender roles and abilities believed that lesson.

To make the same point in reverse: students who studied a seemingly “neutral” scientific curriculum – “we’re just talking about genes here” – drew unsupported conclusions about absolute differences between men and women.

Amazingly, this finding held true both for the students who studied the genetics of human sexual differences AND those who studied plant sexual differences.

WOW.

Perhaps surprisingly, students who learned that genetic sex differences don’t cause gendered ability differences also expressed a greater interest in science.

In particular, the girls who studied the “genetics only” lesson expressed meaningfully less interest in a science major than those who got the alternative lesson. (The two lessons neither encouraged nor discouraged the boys.)

But, Why?

Here’s the likely causal chain:

A science curriculum that focused “purely” on genetics seemed to suggest that men and women are utterly different beings.

Students who read this “pure” lesson inferred that some human abilities – like, say, scientific competence – might differ between genders.

This inference, in turn, made gender stereotypes (e.g., “men do better at science than women”) more plausible.

And so, the women who got that seemingly neutral science lesson, discouraged by the stereotype it reinforced, felt less inclined to pursue science.

By this roundabout route, a traditional science lesson might itself discourage students from learning science.

Alternative Explanations

Of course, the topic of gender differences – especially in the realms of math and science – can generate lots of energetic debate.

When I asked Donovan for alternative explanations for his findings, he was quick to emphasize that we need lots more research in this field. His is the first study done on this specific question. As always, teachers shouldn’t assume that any one study has found THE answer.

Some people do in fact argue that math and science ability (or interest) differ by gender because of genes. (Dr. Donovan explicitly rejects an explanation that moves directly from genes to gender differences.)

Here’s a recent book review by Lise Eliot, emphasizing that gender differences in brain regions

a) are often exaggerated and mis-reported, and

b) result from societies that emphasize gender differences.

For others – like Simon Baron-Cohen – that argument goes too far. Another recent study suggests that brains differ by gender in utero — that is, before socialization can have strong effects upon them.

Teaching Implications

Donovan’s research suggests that teachers can and should do more to be sure we’re not discouraging some students from particular academic interests and career paths.

For one set of practical suggestions, this interview with Sapna Cheryan outlines several ways we can promote “ambient belonging” in our classrooms.

Taking Notes with Graphic Organizers

Read More

research-based advice for studentsWe’ve blogged (quite energetically) about the difference between handwritten and laptop notes.

Of course, other note-taking differences merit investigation as well.

For example: if students take handwritten notes, is it better to give them:

a complete lecture outline,

a partial lecture outline,

a bare-bones lecture outline,

or

a complete graphic organizer,

a partial one, or

an empty one?

Over at the Learning Scientists, Carolina Kuepper-Tetzel explores this question, and adds some thoughts of her own.

One Man’s Experience

This article particular caught my eye because it applies so directly to my own work.

When I talk with teachers, students, or parents about brains, I always provide them with option #5 above: an incomplete graphic organizer.

My goal: reduce working memory load. (I’m always focused on reducing extraneous working memory load.)

The informal feedback I get is strongly positive. Many teachers, in fact, tell me that they’ve started using the same form with their own students.

When you read Dr. Kuepper-Tetzel’s post, you’ll see how well (if at all) my practice accords with the research we have.

Do Collaborative Projects Reduce or Increase Working Memory Stress?

Do Collaborative Projects Reduce or Increase Working Memory Stress?

Read More

Should teachers ask students to work on projects in teams?

This question generates a great deal of heat.

Many education thinkers advocate for the benefits of teamwork. Others insist that learning happens one brain at a time, and so should not be cluttered with interference from other brains.

Working Memory: Blesses and Curses

Working memory allows humans to hold and reorganize facts and ideas in temporary mental storage.

When you do a word problem, you must decide which parts should be translated into an equation. (Those decisions take WM.) You have to recall the appropriate equation to use. (Ditto.) And, you must plug the correct data into the correct formula before you can arrive at an answer. (Re-ditto.)

Composing a new sentence in a foreign language? Lots of working memory demands.

Comparing Paul Lawrence Dunbar’s poetry with that of Countee Cullen? Yup.

Learning how to tell time? Once again – lots of working memory involved.

In other words, WM allows students to do practically everything that we want them to do in school.

And yet, this working memory blessing co-exists with a powerful curse: we just don’t have very much of it.

You probably can alphabetize five days of the work week. You probably can’t alphabetize 10 months of the year. The first task lies within WM limits; alas, the second goes way beyond them.

Collaboration’s WM Dangers

In a recent article, Paul Kirschner and others consider the WM benefits and perils of group work.

(These scholars, especially John Sweller, have elaborated “cognitive load theory” to explain the relationship between long-term memory, WM, and the external world of perception and experience. See here for a review.)

One important peril: the working memory demands created by collaboration. When students work together, they have to negotiate roles. They must create joint mental models. They have to schedule and prioritize and debate.

All these “musts” take up precious working memory space. The result might be that students get better at negotiating, modeling, and prioritizing. But, the WM devoted to those task might make it harder for them to learn the content at the heart of the project.

Of course: you might reasonably want your students to focus on the social-emotional skills. But, if you wanted them to focus on Shakespeare or Boyle’s law, then the project might not produce the results you hoped for.

Collaboration’s WM Benefits

At the same time, Kirschner & Co. also see working memory upsides to collaboration.

A particular cognitive task might include quite stiff WM demands. If the group includes members with the right kinds of background knowledge, then the WM chores can be divided up and managed more effectively.

Student A carries this part of the WM load.

Student B carries that part.

Student C takes care of the tricky last bit.

In this way, the WM whole can be greater than the sum of the parts.

In other words: if teachers can organize group projects so that a) the WM difficulties of collaboration remain low, and b) the benefits of sharing WM burdens remain high, then such collaboration truly help students learn.

Putting It Together

Kirschner’s article concludes with a list of key variables for teachers to track: task complexity, domain expertise, team size, and so forth.

Be aware that cognitive load theory gets a little jargony, and you’ll need some time to learn the lingo before the article makes sense.

However, if you can devote that time, I think you’ll benefit from its practical suggestions, and helpful frameworks for planning students’ collaborative learning.

There’s No Polite Way to Say “I Told You So”

Read More

Back in 2014, Pam Mueller and Dan Oppenheimer made headlines with their wittily titled study “The Pen Is Mightier Than The Keyboard.”

In that study, they found that students learn more from taking handwritten notes during a lecture than from laptop notes. Their conclusions spawned a thousand gloating posts. And (I don’t doubt) a multitude of well-intentioned anti-laptop policies.

Since I first read the study, I’ve been shouting that its conclusions simply don’t hold up.

Why?

Because M&O’s conclusions hold water only if you believe students can’t learn new things.

(That’s a very strange belief for teachers to have.)

If you believe that students can learn new things, then you believe that they can learn to take laptop notes correctly.

(“Correctly” = “rewriting the lecture’s main points in your own words; don’t just transcribe verbatim”)

If they do that, then this famous study actually suggests laptop notes will enhance learning, not detract from it.

You can find a summary of my argument — and its limitations — here.

Today’s News

Scholars have recently published an attempt at replication of Mueller & Oppenheimer’s study.

The results? Not much.

In the quiet language of research, they conclude:

“Based on the present outcomes and other available evidence, concluding which method [handwriting or laptops] is superior for improving the functions of note-taking seems premature.”

Not so much with the mighty pen.

By the way: a study from 2018 also concluded that — except in special circumstances — it just didn’t make much difference which method students use.

Why I Care

Perhaps surprisingly, I’m not an ardent advocate of laptop notes. Or, for that matter, of handwritten notes.

I advocate for teachers making classroom decisions informed by good research.

In this case, the Mueller and Oppenheimer study contains a perfectly obvious flaw. I have yet to meet anyone who doesn’t think a) that students can learn good note-taking skills, and b) that if they do, the study’s conclusions make no sense.

And yet, very few people have time to dig into research methodology. As a result, this one study had confirmed many teachers in their beliefs that technology harms learning during note-taking.

That statement might be true. It might be false. But this one study doesn’t give us good data to answer the question.

As a result, teachers might be taking laptops away from students who would learn more if they got to use them.

In brief: bad research harms learning.

I hope that this most recent study encourages teachers to rethink our classroom practices.

Two Helpful Strategies to Lessen Exam Stresses

Read More

Exam stress bothers many of our students. Sadly, it hinders students from lower socio-economic status (SES) families even more.

As a result, these students struggle — especially in STEM classes. And, exam stressthis struggle makes it harder for them to enter these important (and lucrative!) fields.

Can we break this cycle somehow?

Reducing Exam Stress: Two Approaches

Christopher Rozek tried a combination of strategies to help lower-SES science students manage exam stress.

This research stands out for a number of reasons: in particular, it included a large sample (almost 1200 students). And, it took place in a school, not a psychology lab. That is, his results apply to the “real world,” not just a hermetically sealed research space.

Rozek worked with students taking a 9th grade biology class. Before they took the two exams in the course, Rozek had students write for ten minutes.

One group spent their ten minutes writing about their current thoughts and feelings. This approach lets students “dump” their anxiety, and has been effective in earlier studies. (By the way: this earlier research is controversial. I’ve written about that controversy here.)

Another group read a brief article showing that the right amount of stress can enhance performance. This reading, and the writing they did about it, helps students “reappraise” the stress they feel.

A third group did shortened versions of both “dumping” and “reappraising” exercises.

And the control group read and wrote about the importance of ignoring and suppressing negative/stressful emotions.

So, did the “dump” strategy or the “reappraise” strategy help?

Dramatic Results

Indeed, they both did.

For example, Rozek and Co. measured the effect these strategies (alone or together) had on the exam-score gap between high- and low-SES students.

The result? They cut the gap by 29%.

Rozek also tracked course failure. Among low-SES students, these strategies cut the failure rate by 50%.

(In the control group, 36% of the low SES students failed the class; in the other three groups, that rate fell to 18%. Of course, 18% is high — but it’s dramatically lower than 36%.)

In his final measure, Rozek found that — after these interventions — low SES-students evaluated their stress much more like the high SES-students. The gap between these ratings fell…by 81%.

All this progress from a 10 minute writing exercise.

Classroom Guidance to Reduce Exam Stress

If you’ve got students who are likely to feel higher levels of anxiety before a test, you might adapt either (or both) of these strategies for your students.

The best way to make these strategies work will vary depending on your students’ age and academic experience.

You might start by reviewing Rozek’s research — click the link above, and look for the “Procedure” section on page 5. From there, use your teacherly wisdom to make those procedures fit your students, your classroom, and you.
