When Homework Is (and Isn’t) Genuinely Helpful
Andrew Watson
Andrew Watson

Back in October, I posted a link to a pro-homework argument. Again today, I’ve stumbled across another–this one summarizing John Hattie’s Visible Learning on the subject.

Author Tom Sherrington makes two general points.

First: the question “does homework help students learn” is too broad. We need to narrow it down. What age student are we discussing? What kind of homework are they doing? What discipline are they studying?

This first point is often worth making. If someone asks you, “Is technology good for learning?” remember that the question is too big to answer sensibly. Likewise: “does gender matter for learning?” Or “can we train brains?”

Research can answer narrow question very well. The bigger the question, the less certain our answer.

Second: the brief answer to the question is: homework is helpful for older students, but not for younger ones.

Of course, as outlined above, that brief answer requires lots of elaboration.

I live in Boston. I’m a Tom Brady fan. But, good heavens, his Brain Training program looks like snake oil.

The website (and, no, I’m not providing a link) uses all the right buzzwords: “brain plasticity,” “personalize,” “money-back guarantee!”

Some of the claims have a surface plausibility. You can, in fact, train your ability to track objects in space. Video games can do that for you, too.

But the idea that all of this comes together to promote “brain speed” and “intelligence” seems laughable. (I don’t know what “brain speed” even means.)

The Recent History of “Brain Training”

Always remember: Lumosity was fined $2,000,000 for making false claims sounding like these. I suppose it’s possible that Brady’s Brain Team has cracked a code that no one else has. But, it seems mightily unlikely.

I’m so vexed that I’m tempted to make a joke about Deflate-gate. For a Patriots fan, that’s as bad as it gets.

Focus on the Speaker: Charles Fadel Champions Curriculum Redesign

Charles Fadel will be speaking on “Creativity, Curiosity, and Collaboration” at the upcoming Learning & the Brain conference.

He is the founder of the Center for Curriculum Redesign at Harvard’s Graduate School of Education.

The Innovative Mission of the Center for Curriculum Redesign

Andrew Watson:

Most educational reform focuses on the way the teaching happens: project based learning, or flipped classrooms, or technology, or that sort of thing. Your focus is more on curriculum, which is to say, what it is that teachers are actually teaching. Why have you chosen that focus, instead of the method of teaching?

Charles Fadel:

When I was at Cisco, we started the Partnership for 21st Century Skills; we started looking at the skills that make people successful all their life.

But as I started getting more and more into this question, I realized—wow!—in the past 50 or so years everyone has been so focused on how to teach better, because somehow we assumed that what we taught was adequate. And it was probably adequate since the Industrial revolution, to a point. But nowadays, it’s really not adequate anymore.

There are several difficulties with this question.

First of all, if the curricula are already chock-full of knowledge items, there is no time and space available to teach skills, and character qualities, and meta-learning abilities. And systems are very, very resistant to removing some things so that there might be time and space for these new competencies.

Second, there are all sort of human dynamics at play. Do you think that a literature expert will say, “Well, that’s fine, we can just read two books this year, and the other eight we’re just going to do cliff notes.” That’s never going to happen. Right?

Naturally enough, everyone considers that their discipline is the most important thing, and they’re not going to let go of it. We call this “expert (confirmation) bias.”

Third you have the politics. As I go around the world, I realize to what extent the curriculum is prisoner of parliaments and politicians. And they, for political expediency’s sake, decide some of the things that are taught. Whether it’s history, or languages, or so on—and these decisions also crowd the curriculum.

Funny enough, parliaments don’t have too many opinions about maths…

Andrew Watson:

People are generally in favor of math.

Charles Fadel:

Well, yes, we are too, but should that mean that we abdicate our responsibility entirely to the hands of maths academics? Who have no idea about how math is used in the real world.

So, for all of these reasons, I realized—wow!—the curriculum is in trouble. What should we be learning?

Do we need to learn the multiplication tables? Yes, no, and why?

Do we need to learn long division? Yes, no, and why?

How do we decide? And how can we remove obsolete and extraneous items to make time and space for

  1. deepening understanding of traditional disciplines (Maths, History etc.),
  2. adding modern branches to the traditional disciplines, like say adding algorithmics to mathematics, not just algebra and geometry,
  3. adding modern disciplines, like entrepreneurship, robotics, etc. and
  4. very importantly, combining all these disciplines with the competencies that need to be developed. By “competencies” I mean skills, character, and meta-learning.

How in the world are we going to do all this unless we curate what’s already on the dockets?

Andrew Watson:

How hard can that be?

Charles Fadel:

The current curriculum a bit like a budget deficit, you know. Every single line item you can justify in insolation from the rest. You know this restaurant you went to with your significant other, that was a good thing to do in isolation. But, you do this too many times and you’ve broken your budget.

So every single line item in the curriculum needs to be scrutinized, and that’s not something that disciplinary expert groups are particularly well suited to do left on their own—because of the “expert bias” I described before.

Andrew Watson:

I can tell you from my own school experience that the battles fought over curricular changes are quite fierce. So, it’s a good thing the Center for Curriculum Redesign exists.

Charles Fadel:

We at the Center are non-political and non-dogmatic. We don’t have an axe to grind; we can look at all these things more cold-bloodedly and say “you know what, after analyzing and polling, we haven’t heard a profound justification for why long division should stay, therefore it goes …”

Curriculum Redesign to Foster Creativity, Curiosity, Collaboration

Andrew Watson:

Okay. I’m going to change gears to introduce your talk at the up-coming Learning and the Brain conference. That talk, as I understand it, focuses on creativity, curiosity and collaboration, which are in the Skills portion of your book.

Charles Fadel:

Actually “creativity” and “collaboration” are Skills, but “curiosity” is in the Character portion.

Andrew Watson:

Oh right, okay. I want to think about those topics in reverse order.

Starting with collaboration: Is the way to teach collaboration just say, “Hey everybody, you have to work together to perform this task” and assume they’ll figure out how to collaborate? Or is it a skill we can teach with a collaboration curriculum? If “yes,” how do we do that?

Charles Fadel:

Any single one of these 12 competencies that we have identified in the book’s framework can be taught.

It’s not enough to say “Here, we’re going to throw you in a collaborative situation, good luck to you.”

The same way that there are better techniques for how to deploy projects, there are better techniques for how to collaborate. For instance, by understanding the psychological make up of your team members.

In the corporate world, for example, we use the Myers-Briggs Type Indicator. I’m not saying that the Myers-Briggs has huge science behind it, but I’m saying that it’s a facilitator of the conversations of team members.

Andrew Watson:

Understood.

Charles Fadel:

The Myers-Briggs test might say, this person has a certain dominant personality characteristic, and that’s why they are not comfortable making decisions right away. Whereas I’ll be tempted to just jump to a conclusion and make a decision early on.

The test helps me take a deep breath about my own behavior, about their behavior. It forces certain metacognitive views of people and the world.

So that’s the sort of thing you can do to understand yourself and others better. That’s part of what you would want to learn to better collaborate.

You can also teach certain group principles, such as respect. Making sure that everyone has a chance to speak. Even that shy introvert in the corner. Make sure the team leader puts the spotlight on them and says, “you can you speak now, or if you’d be more comfortable you could send me an email.” Et cetera.

So, there are all sorts of techniques. To use communication analogy: the same way that they tell you “don’t wear a striped shirt when you go on camera,” you know there are plenty of tips and tricks that one needs to know to improve collaboration.

And so all of these things need to be taught. In fact, they should first be taught to teachers, because they have not necessarily been in a collaborative environment themselves. It’s such an isolated profession!

Andrew Watson:

Got it. Let’s talk a little bit about curiosity. Schools have a really bad reputation about curiosity and are often are accused of interfering with curiosity. Can you think of ways we would be better at promoting curiosity?

Charles Fadel:

Right, so first let’s have a balanced conversation about how schools are “bad at creativity.”

Remember, schools have to cover a certain amount of material in a certain period of time. Yes, we want to give students enough agency and free will to learn things their own way. But at the same time, there’s not an infinite time to allow them to experiment forever.

And so that’s the complexity of the balance to strike.

Now can traditional schooling do a far better job? Absolutely.

But I’m saying schools don’t have to be entirely one way or the other. Just as research shows that we need to have the right balance between didactic instruction and constructivism/projects, we also have to have the right balance of student choice and student non-choice.

Now, should we err in the direction of student choice right now? Yes, because we’ve gone too far in the wrong direction of non-choice.

With that said, there are ways to bring these approaches together.

For instance, let’s say that the curriculum says you’ve got to learn robotics. The choices could be: well I’m going to do a swimming robot, and you’re going to do a flying robot, then the third person is going to do an underwater robot. But Robotics are important so everyone has to learn that – their own way.

And you can have finer-grade choices as well.

Everyone does need to understand robotics, but we don’t all need to go beyond basic skills in programming.

If that is not where my forte is, I’m going to devote more of my time to making the robot emote and mimic emotion—because that’s what I’m attracted to. I want to go into anthropology later, so emotions are my interest.

So you see, there’s a blend of requirements and choices: meaning, even the anthropologist has to understand how to code. But, the anthropologist doesn’t have to be the best possible coder.

You’d say “okay anthropologist, you got passing grades in coding, move on. You don’t have to be the best one, but at least you understand the principles of coding, and now we can have you focus on the thing that jazzes you up – and know how to interface with the coder when needed later.”

So we recommend a constant blend of choice and prescription.

There’s an important graph we have in the book. The ratio between choice and prescription changes over time.

CF Prescription

When they’re young kids, most of the curriculum is going to be prescribed. We’re not going to let you decide whether or not you want to learn how to read and write and compute. It’s just not a choice. Otherwise you’re not going to be a functional member of modern society, your chances will be severely truncated…

But, by high school, it’s certainly clear that if you want to do a given type of project, you should have some latitude. And so the ratio of prescription to choice changes over time.

Andrew Watson:

In some ways it sounds like curiosity and collaboration work well together. Because I’m curious about anthropology, I’m going to collaborate with someone who has more technical skills in this robot building process. The fact that I’m working collaboratively in a team means I get the focus on the thing I’m most particularly curious about.

Charles Fadel:

Yes. These 12 competencies are not isolated; they’re not silos in our brains. All 12 interplay with each other.

Andrew Watson:

Let’s change gears and think about creativity. What strategies do you see out there that are going to be helpful in teaching students creativity?

Charles Fadel:

Remember that CCR focuses on the what—the curriculum—not the how—the teaching methods. If your questions relate to classroom techniques, I’m really not the right person to ask.

But, we have to be clear about the where. These competencies must be practiced in as many disciplines as possible.

We might be tempted to say: “arts teach creativity.” Well for creativity to stick – to transfer – it has to be activated in several different disciplines. We would want as many disciplines as possible to develop as many competencies as possible.

At the same time, let’s not fool ourselves. It may be a bit exaggerated to say that every discipline can help with every competency.

Andrew Watson:

So for all three of these—for collaboration, curiosity and creativity—you’re not at this point advocating teaching strategies. You’re making an argument that we have to teach these competencies, and you’re putting together a cognitive framework to help teachers think about how they inter-relate with each other.

Charles Fadel:

We’re trying to make sure that—at a minimum—each discipline is tasked or not tasked in developing them. Could you teach collaboration in every single discipline? Yes. Are some—like engineering and art—more conducive to that? Yes.

Part of the complexity is that teachers want to say: yes, I agree with you. Let’s all teach collaboration. However, perhaps some disciplines are better suited for some competencies than others. It’s exaggerated for every discipline to think that they’re going to do everything.

“Incremental Ambition”

Andrew Watson:

In the book, you describe your work as “incrementally ambitious,” which is a very fun phrasing. Can you unpack that a little bit?

Charles Fadel:

Sure. If you use a word like “radical,” it sounds good for getting on the New York Times front page. But, you know, that’s really not the point.

“Radical” implies you throw away the existing system. You “disrupt,” which is a term that is so over-used.

We want to profoundly change, but in an evolutionary, not revolutionary sort of way.

Now I hear the irritation of those who say, “to hell with the system. It’s not listening; therefore I’m going to take it down.”

But it’s a lot easier to take down than to build. And so the challenge for the CCR is change management.  That’s why we have to be ambitious, but incrementally so.

CF Pyramids

Andrew Watson:

The people who are at Learning and the Brain conferences, by definition, those are people who want to change what we’re doing. But, we don’t want the change to mean that everything we’ve ever worked for goes away. We want to be better at what we’re doing. Which is why the ambition has to be incremental.

Charles Fadel:

It’s a lot easier to hope for some magic solution, perhaps using technology, some extraordinary e-tutor. You just hope, oh if I only had a magic wand. That’s not the way the world works.

Andrew Watson:

If a magic wand exists, we haven’t found it in the teaching world yet.

Charles Fadel:

Or in the technology world.

Andrew Watson:

Thank you for taking the time to talk with me today.

Charles Fadel:

You’re welcome.

Center for Curriculum Redesign

The mission of the Center for Curriculum Redesign (CCR) is to answer this timely question, and openly propagate its recommendations and frameworks on a worldwide basis. The CCR brings together non-governmental organizations, jurisdictions, academic institutions, corporations, and non-profit organizations including foundations.

The last major changes to curriculum were effected in the late 1800’s as a response to the sudden growth in societal and human capital needs. As the world of the 21st century bears little resemblance to that of the 19th century, education curricula need to be deeply redesigned for the four dimensions of Knowledge, Skills, Character and Meta-Learning.  Adapting to 21st century needs means revisiting each dimension and the interplay between them.

This paper outlines the CCR model for curriculum redesign.

Benefiting from Retrieval Practice: Get the Timing Just Right
Andrew Watson
Andrew Watson

Retrieval Practice Timing Affects its Benefits

I’ve posted a lot here recently about retrieval practice: the practice of reviewing material by pulling it OUT of the student’s head rather than trying to put it back IN.

For example: if I ask my students to write down the 5 main points from yesterday’s class about the Buddha, that’s retrieval practice. They have to get info out of their heads.

If, instead, I remind them of the 5 main points from yesterday’s class, that’s not retrieval practice. After all, I’m putting information back in.

The short sales pitch for retrieval practice is: it works for all students in all subjects, all the time. (Ask Dr. Pooja Agarwal.)

Unless…

Of course, all students in all subjects all the time is quite a grand claim. It’s rare for any teaching practice to work all the time, so we should be on the lookout for boundary conditions.

And, indeed, one has recently jumped out at me.

The story is interestingly complicated. I promise, however, that a close study of this complexity leads to specific and useful teaching advice. So: hang in there!

When Retrieval Practice Timing Might Be Bad

Imagine that, in yesterday’s class, we went over ten definitions for key economics terms. I want to begin today’s class with a quick review, so we go back over five of those terms.

My assumption is that, by reviewing five, I’m actually helping you to remember all ten.

Here’s the surprising research finding: by practicing some of the terms, I actually make it LESS LIKELY that you’ll remember the unpracticed terms.

In other words: recalling some of the words prompts you to forget the unpracticed words.

Psychologists call this bizarre result retrieval-induced forgetting. After all, the retrieval — that is, the practice — induced you to forget.

When Research Fields Contradict

So: the retrieval practice research says that retrieval is beneficial for memory.

And: the retrieval-induced forgetting research says that retrieval is detrimental for memory.

What happens when teachers do both? Does one cancel out the other? Can Superman defeat Iron Man?

Research done by Jason CK Chan helps answer this intriguing question.

The short answer is: in the short term, retrieval-induced forgetting is stronger. So: if I quiz you on five of those economics terms, and then give you the final test on those terms an hour later, you’re more likely to forget the five unpracticed words.

However, in the longer term, retrieval practice is stronger. So: the quiz on five terms will benefit you if you take that final test 24 hours later.

This result is especially likely if my quiz encourages you to think about how these five words connect conceptually to the other words.

Practical Advice

Although these research findings can be difficult to follow, they do all lead to a specific suggestion.

Retrieval practice is an excellent study strategy for students more than 24 hours ahead of a test. However, within that 24 hour window, teachers and students should focus more on connecting ideas rather than recalling them.

To update Dr. Agarwal’s guidance: retrieval practice works for all students in all subjects, (almost) all the time.

An Extra Half-Hour of Sleep? An Extra Hour?

If you’ve ever met a teenager, you might be skeptical about the idea of starting high-school classes later. After all, you might worry that they’ll just stay up later. They are, after all, teenagers…

What does research on high school start time say?

According to a recent study done by Penn State researchers, you needn’t worry. Later high-school start times do in fact translate into more sleep.

Specifically: students whose first class started later than 8:30 got between 27 and 57 (!) more minutes of sleep. Imagine just how much more learning might happen if a teen regularly got an extra hour of sleep.

The researchers based these conclusions on sleep diaries that lasted only a week; I’d be more persuaded if they had data from a longer period of time.

However, this finding does echo a conclusion that I reported on back in April. Given these converging data–and, frankly, common sense–I’m inclined to believe that later start times really do help students get more sleep.

Enhance Memory by Saying Important Words Aloud
Andrew Watson
Andrew Watson

Reading Words Out Loud Enhances Memory

You’d like to remember a list of words better? Here’s a simple trick: say them aloud to yourself.

According to recent research by Forrin and MacLeod, the benefits of both reading and  saying words out loud are greater than either reading or saying the words.

When going over flashcards of essential chemistry terms — for example — students might say the definitions as they review them. This strategy should help them learn those definitions better.

Practical limitations of saying words aloud

As I think about the teaching implications of this research, I don’t think we should encourage students to read everything aloud. (Except, of course, students who are learning to read.)

Instead, we should suggest this technique as a study supplement for a few key concepts: the definitions or formulas that we most want them to learn.

This strategy takes little time and costs nothing. In other words, it’s perfect for the world of education.

 

Frequency and Memory: Essential Brain Wave Boost
Andrew Watson
Andrew Watson

Brain wave frequency

Earlier this month, I linked to a study showing that declarative and procedural memories correspond with different brain-wave frequencies.

This week: another study making a similar point. Researchers have found that frontal, temporal, and medial temporal lobes align neural activity at lower frequencies as new memories are formed. (At higher frequencies, neural alignment is weaker.)

Networks and Brain Waves

As lead author Ethan Solomon says,

This suggests that, for someone to form new memories, two functions must happen simultaneously: brain regions must individually process a stimulus, and then those regions must communicate with each other at low frequencies.

I suspect that over the next few years, our understanding of long-term memory formation will move in this direction. That is, we will increasingly combine the study of synapse formation between neurons with the study of frequency alignment among brain regions.

That account will doubtless be more complex. But: if it’s more accurate, that complexity will ultimately be more helpful to us all.

Looking Forward to 2nd Grade

When I was in grad school, Kurt Fischer often said “when it comes to understanding brains, we’re still in first grade.”

He meant that the brain is just so complicated, we have only just begun to understand it.

For teachers interested in neuroscience, this truth has a powerful consequence. Much of what we learn about the brain today will be understood differently next year. It might be quaint in ten years.

 

Mindset, Gender, and Intelligence: Confusing Myth or Painful Truth
Andrew Watson
Andrew Watson

AdobeStock_54087355_Credit

You doubtless know that Mindset Theory has been increasingly doubted–and increasingly defended–in the last two years or so.

(In this post, for example, the author updates his earlier criticism of Mindset Theory and largely ends up defending Dweck–or, at least, criticizing her critic. His back-n-forth on this question helpfully represents the nature of the current debate.)

Today’s News

A recently published study looks carefully at a specific set of claims often advanced in Mindset world:

First: that girls and women have a fixed mindset more often than boys and men, and

Second: the smarter the girls and women, the likelier they are to have fixed mindsets.

In other words, for Mindset

First: gender matters, and

Second: for girls and women, intelligence matters.

What Did The Researchers Find?

Nope, and nope.

In their research, which included not only college students but also adults in the population at large, Macnamara and Rupani found no consistent patterns in either direction.

That is: in their research, there was no consistent gender split on Mindset. And, for men as well as women, intelligence level didn’t consistently influence Mindset; nor did a Growth Mindset predict academic accomplishment.

In truth, as you’ll see if you look at the graphs, they got quite a complex muddle of results. It’s genuinely difficult to pick out meaningful patterns in all their data.

What Next?

In my experience, Dweck tends to be quite open and responsive to thoughtful critique. Unlike some researchers who refuse to recognize those who disagree with their work, she is remarkably comfortable acknowledging debate and rethinking her own research.

So: I’ll be curious to see if and how she responds to this study.

There is, by the way, a broader message here as well. Although Mindset Theory is quite well established in the field of education, it is still up for discussion in the field of psychology.

Those of us who shape our classrooms and our schools with such theories in mind should be sure to check back in and see if they are holding up over time.

 

The Neuroscience of Morality
Andrew Watson
Andrew Watson

AdobeStock_164544380_Credit

How do brains encode moral impulses?

As you can imagine, that’s an extraordinarily difficult question–in part because definitions of morality can be tricky in the first place.

In this study, researchers study the neural underpinnings of moral decisions–particularly decisions not to harm other people. The findings are quite complicated–lots of talk about the lateral pre-frontal cortex–but a fascinating glimpse into our moral/neural selves.
