Just Not a Useful Debate: Learning Styles Theory [Updated]
Andrew Watson
Andrew Watson

At one of the first Learning and the Brain conferences I attended, a speaker briefly mentioned that learning styles theory doesn’t have much good evidence to support it.

learning styles

That comment turned into a heated debate. Several attendees asked vexed, unhappy questions. The speaker held her ground.

When I got in the elevator at the end of that session, I heard one attendee curtly dismiss the speaker’s objection: “well, it’s all just statistics.”

It’s All Just Statistics

Well, it IS all statistics.

In the worlds of neuroscience and psychology, researchers rely on statistical methods to ensure their recommendations aren’t simply hunches.

Anyone can stand behind a microphone and have an opinion. But: if you’re going to do scientific research, your numbers have to add up.

And, as researchers look at valid statistical models, they just don’t find good support for the idea that — for instance — some people are visual learners and others are auditory learners.

The numbers just don’t add up. Or, in this case: if you teach “visual learners” “visually,” they don’t learn any more than if you had taught them “auditorily” or “kinesthetically.”

Multiple Entry Points

Instead, the content itself often offers guidance on the best way to teach. If you’re teaching a French or Spanish or Japanese accent, that content is — by its nature — auditory.

If you’re teaching geography, that content is visual.

Free throws? Kinesthetic.

Most content, however, can be taught in multiple ways.

For example: I’m thinking of an actress. She’s Australian. She played Virginia Woolf in that movie. And, she was married to Tom Cruise.

If you’re shouting NICOLE KIDMAN, you’re right. Notice that I gave you three entry points to the neural network that encodes this memory: her country of origin, a role she played, and her marriage.

So: “teaching to learning styles” helps because you probably teach your content in different ways — auditorily, visually, and kinesthetically. Those three different approaches give distinct connections to the memory you want your students to form.

This approach to teaching helps not because of a student’s learning style, but because all your students now have multiple ways to access that memory.

In other words, the theory helps students learn — but not for the reason it claims to.

“Learning Styles”: Today’s News

Daniel Willingham — one of the early debunkers of learning styles myths — has recently posted his current thoughts on learning styles. The short version:

Nope. Learning Styles still don’t exist. Really.

Learners should “tune their thinking to the task.” That is: learn about geography visually — even if you think you’re not a “visual learner.”

More than many researchers, Willingham gets teachers and teaching. So: if you’re still a learning-styles believer, I encourage you to check out his article.

 

In related news: Greg Ashman argues that, no, rejecting learning styles theory isn’t sexist. After all, LOTS of thoughtful female researchers reject the theory.

And: the Learning Scientists have a great take on this debate. We shouldn’t focus simply on rejecting learning styles theory. Instead, we should replace it with a better theory. They have thoughts on how to do so

[Update, 6/25/18]

Finally, Scientific American has a recent article showing that most students don’t use the learning styles that they believe would benefit them. And, when they do, those strategies don’t help them learn.

Unless you’ve been napping under a LatB rock, you’ve heard about the importance of research-based study habits.

study habits

In particular, you know that students should spread practice out over time rather than bunching practice all together. (The benefits are called the spacing effect.)

And, you know that students should not simply look over what they already know. Instead, they should quiz themselves to see what they can actively retrieve from memory. (That’s called retrieval practice.)

Here’s a little secret you might not know: most of the research about the spacing effect and retrieval practice takes place in psychology labs.

What happens in the real world? Do students who use these techniques actually learn more than those who don’t?

Asking Students about their Study Habits

In a recent study, Fernando Rodriguez and colleagues surveyed students about their study practices.

Do these students space practice over time? Do they do all of their studying all in one session?

Perhaps they quiz themselves on what they know? Or, perhaps they reread the textbook?

Rodriguez & Co. then compared these answers to the students’ grade in the class. By this method, they could tease out the effects of spacing and retrieval practice on actual learning.

So: did these research-endorsed study habits translate into classroom learning?

No. And, Yes.

Rodriguez found mixed results.

Study habits that spaced practice out didn’t make any difference. Students who crammed and students who studied material in several brief sessions got the same final grade.

(I’ll propose an explanation for this finding below.)

However, retrieval practice made a clearly measurable difference. Students who reviewed material averaged a B-. Those who self-tested averaged a B.

Given that both study techniques take the same amount of time, it obviously makes sense to self-test. Students who do so learn more. Retrieval practice just works.

Spacing Doesn’t Help? Or, Spacing Already Helped?

If we’ve got so much research showing the benefits of spacing, why didn’t it help students in this class?

We don’t know for sure, but one answer stands out as very probable: the professor already did the spacing for the students.

That is: the syllabus included frequent review sessions. It had several cumulative tests. The class structure itself required students to think about the material several times over the semester.

Even if students wanted to cram, they couldn’t wait until the last moment to review. The test schedule alone required them to review multiple times.

So: the students’ own additional spacing study habits didn’t help.

However, in a class where the professor hadn’t required spacing, it most likely would have done so.

The Bigger Picture

This possibility, in my view, underlines a bigger point about spacing and retrieval practice:

For the most part, students have primary responsibility for retrieval practice, whereas teachers have primary responsibility for spacing.

That is: students — especially older students — should learn to review by using retrieval practice strategies. (Of course, especially with younger students, teachers should teach RP strategies. And, offer frequent reminders.)

Teachers — in our turn — should design our courses to space practice out. (Of course, students should do what they can to space practice as well.)

In other words: retrieval practice is largely a study habit. Spacing is largely a teaching habit.

Students will get the most benefit from this research when we divide up responsibility this way.

The Best Way to Take Notes: More Feisty Debate
Andrew Watson
Andrew Watson

Over at The Learning Scientists, Carolina Kuepper-Tetzel asks: is it better to take longhand notes? Or to annotate slides provided by the speaker? Or, perhaps, simply to listen attentively?

longhand notes

(Notice, by the way, that she’s not exploring the vexed question of longhand notes vs. laptop notes.)

Before we get to her answer, it’s helpful to ask a framing question: how do brain scientists approach that topic in the first place? What lenses might they use to examine it?

Lens #1: The Right Level of Difficulty

Cognitive scientists often focus on desirable difficulties.

Students might want their learning to be as easy as possible. But, we’ve got lots of research to show that easy learning doesn’t stick.

For instance: reviewing notes makes students feel good about their learning, because they recognize a great deal of what they wrote down. “I remember that! I must have learned it!”

However, that easy recognition doesn’t improve learning. Instead, self-testing is MUCH more helpful. (Check out retrievalpractice.org for a survey of this research, and lots of helpful strategies.)

Of course, we need to find the right level of difficulty. Like Goldilocks, we seek out a teaching strategy that’s neither too tough nor too easy.

In the world of note-taking, the desirable-difficulty lens offers some hypotheses.

On the one hand, taking longhand notes might require just the right level of difficulty. Students struggle — a bit, but not too much — to distinguish the key ideas from the supporting examples. They worry — but not a lot — about defining all the key terms just right.

In this case, handwritten notes will benefit learning.

On the other hand, taking longhand notes might tax students’ cognitive capacities too much.  They might not be able to sort ideas from examples, or to recall definitions long enough to write them down.

In this case, handing out the slides to annotate will reduce undesirable levels of difficulty.

Lens #2: Working Memory Overload

Academic learning requires students to

focus on particular bits of information,

hold them in mind,

reorganize and combine them into some new mental pattern.

We’ve got a particular cognitive capacity that allows us to do that. It’s called working memory. (Here’s a recent post about WM, if you’d like a refresher.)

Alas, people need WM to learn in schools, but we don’t have very much of it. All too frequently, working memory overload prevents students from learning.

Here’s a key problem with taking longhand notes: to do so, I use my working memory to

focus on the speaker

understand her ideas

decide which ones merit writing down

reword those ideas into simpler form (because I can’t write as fast as she speaks)

write

(at the same time that I’m deciding, rewording, and writing) continue understanding the ideas in the lecture

(at the same time that I’m rewording, writing, and continuing) continue deciding what’s worth writing down.

That’s a HUGE working memory load.

Clearly, longhand notes keep a high WM load. Providing slides to annotate reduces that load.

Drum Roll, Please…

What does recent research tell us about longhand notes vs. slide annotation? Kuepper-Tetzel, summarizing a recent conference presentation, writes:

participants performed best … when they took longhand notes during the lecture compared to [annotating slides or passively listening].

More intriguing, the group who just passively viewed the lecture performed as well as the group who were given the slides and made annotations.

Whether the lecture was slow- or fast-paced did not change this result.

Longhand notetaking was always more beneficial for long-term retention of knowledge than both annotated slides and passive viewing.

By the way: in the second half of the study, researchers tested students eight weeks later. They found that longhand note-takers did as well as annotators even though they studied less.

It seems that the desirable difficulty of handwriting notes yielded stronger neural networks. Those networks required less reactivation — that is, less study time — to produce equally good test results.

Keep In Mind…

Note that Kuepper-Tetzel is summarizing as-of-yet unpublished research. The peer-review process certainly has its flaws, but it also can provide some degree of confidence. So far, this research hasn’t cleared that bar.

Also note: this research used lectures with a particular level of working memory demand. Some of our students, however, fall below the average in our particular teaching context. They might need more WM support.

We might also be covering especially complicated material on a particular day. That is: the WM challenges in our classes vary from day to day. On the more challenging days, all students might need more WM support.

In these cases, slides to annotate — not longhand notes — might provide the best level of desirable difficulty.

As is always the case, use your best professional judgment as you apply psychology research in your classroom.

The Great Homework Debate: Working Memory Disadvantage?
Andrew Watson
Andrew Watson

Here at Learning and the Brain, we think a lot about the great homework debate.

homework debate

Some scholars rail against homework. Some schools are doing away with it. However, other researchers champion its benefits.

What can brain researchers contribute to this discussion? Knowing what we know about brains and minds, how can we reconsider this argument?

Working Memory in Schools

All academic learning depends on a crucial cognitive capacity: working memory — often abbreviated as WM.

WM allows students to hold pieces of information in mind, while simultaneously reorganizing or combining them.

Clearly, students use WM all the time. For example:

Performing mathematical operations.

Following instructions.

Applying literary terminology.

Combining letters into new words.

Comparing famous figures.

Using scientific principles in new situations.

All these mental operations — and many, many more — require students to hold and process information simultaneously. Whenever students hold and process, they use WM.

Unfortunately, we just don’t have very much of this essential cognitive capacity. As a simple test: you can probably alphabetize the five days of the work week in your head. (Go ahead — try it!)

But, you probably can’t alphabetize the twelve months of the year. Why? You just don’t have enough WM. (Don’t worry: almost nobody does.)

Working Memory and the Homework Debate

A just-published study by Ashley Miller and Nash Unsworth points to a possible connection between WM and our views on homework.

Imagine, for instance, I give my students a list of random words to learn. Later, I ask them to recall words from that list. As you can imagine, the longer the list, the harder that task will be.

As it turns out, a student’s WM influences her performance on that task. The lower her WM, the more she will struggle to recall all those words.

The Miller and Unsworth study adds a crucial twist. As students see the same word list more and more often, the difference between high-WM students and low-WM students gets smaller.

In some ways of measuring, in fact, it simply goes away.

Put simply: repetitive practice can eliminate this functional difference between high-WM and low-WM students.

What’s another name for “repetitive practice”? Homework.

In other words, homework designed in a particular way might help students who traditionally struggle in school. Although a relatively low WM typically makes learning very difficult, a well-structured assignment might ease some of those difficulties.

If teachers could make cognitive life easier for low-WM students, we’d be going a long way to making school more fair and beneficial.

Caveats (Of Course)

First: this argument says that the right kind of homework can help some students. Of course, the wrong kind of homework won’t. In fact, it might be a detriment to most students.

Second: Miller and Unsworth’s study suggests that repetitive practice can reduce the effect of WM differences. However, teachers might struggle to make “repetitive practice” anything other than really, really dull. We’ll need to be insightful and imaginative to ensure that the solution to one problem doesn’t create a new problem.

Third: To be clear: Miller & Unsworth don’t say that their research has implications for assigning homework. However, as I thought over their findings, it seemed the most direct application of this study in a school setting.

Finally: Teachers might object: we rarely ask students to recall random words. This research paradigm simply doesn’t apply to our work.

And yet, we face an awkward truth.

The words that our students learn might not seem random to us, but they nonetheless often seem random to our students.

We know why the words “chlorophyll,” “stomata,” and “Calvin Cycle” are related to each other. However, until our students understand photosynthesis, even that brief list might feel quite random to them.

Words and ideas that live comfortably in teachers’ long-term memory systems must be processed in our students’ WM systems. The right kind of homework just might make that processing easier.

Pro Tips: How To Think Like A Cognitive Scientist
Andrew Watson
Andrew Watson

Here’s an enthusiastic article from down under.

cognitive science principles

The Sydney Morning Herald reports that Victoria University has introduced an “intensive” course model. Students don’t take multiple courses over many weeks. Instead, they take one course for four weeks. Students absorb a full term of learning in one zealous month.

The students interviewed by the paper were enthusiastic. 19-year-old Alice Growden says:

I am learning a lot more; I feel like the information is easier to understand this way. It’s easier to do better. You are not slammed by four different assignments at once. It is much more balanced.

The Morning Herald’s tone (and my Twitter feed) insist on the benefits of these intensive courses. Seemingly only grouchy professors — who fret that they won’t have enough time for research — object.

Cognitive Science Principles, Take 1: The Spacing Effect

Despite this article’s enthusiastic tone, cognitive scientists will quickly doubt the benefits of this “intensive” course schedule.

After all, we have lots of research showing that spreading practice out over time creates more learning than bunching that practice all together.

For instance, Doug Rohrer looks at shorter and longer lengths of time that courses cover topics. His conclusion — in the modest language of research:

Long-term learning is best achieved when the exposures to a concept are distributed over time periods that are longer rather than shorter.

He finds this conclusion to hold even for intensive language courses, where teachers most often champion the strategy.

Many other scholars have reached this same conclusion. Nicholas Cepeda (along with Doug Rohrer, Hal Pasher, and others) worked with more than 1300 students, and retested them up to a year later.

Their conclusion? Spread learning out over time.

This idea holds even for flashcard study strategies.

Pro Tip #1: If you want to think like a cognitive scientist, beware teaching strategies that promote lots of learning in a relatively short time.

Cognitive Science Principles, Take 2: The Illusion of Knowing

As quoted above, student Alice Growden emphasizes the ease with which she learns:

“I am learning a lot more; I feel like the information is easier to understand this way. It’s easier to do better.”

Yet here again, cognitive scientists will be skeptical.

Remember this principle: easy learning doesn’t stick. Instead, teachers should foster a desirable level of difficulty.

In fact, this principle helps explain the principle above. Spreading practice out over time helps students learn better because it creates additional cognitive challenges.

The extra mental work that students do, in turn, creates more enduring neural networks to encode new memories.

Another example: rereading the textbook.

Students LOVE rereading the book, because it’s relatively easy. This study strategy gives them the illusion of knowing. They say to themselves: “I recognize that passage! I must know this!”

Alas, this illusion comforts students, but isn’t helping them learn more.

I frequently cite Nick Soderstrom’s comprehensive article distinguishing between two results of study: performance vs. learning.

Students often believe that if they “perform” well — say, they recognized everything in their notes — then they have studied effectively. Alas, higher early performance often results in less learning.

Pro Tip #2: If you want to think like a cognitive scientist, beware teaching strategies that emphasize how easy new learning will be. Easy learning doesn’t stick.

If you’ve read Lemov’s Teach Like a Champion, you know he focuses not on the theoretical but on the practical.

no grades

When Lemov sees teachers doing something that works (he’s got a rigorous definition of “works”), then he thinks you should do that. When they do something that doesn’t work (ditto), he thinks you should stop.

No Grades, No Meritocracy?

Although lots of people champion doing away with grades, Lemov strongly dissents. In his view, the end of grades would inevitably result in the end of meritocracy.

As you can imagine, his post has prompted a heated debate — much of it articulate and thoughtful. Check it out at the link above.

Let’s Get Practical: More Flashcards Are Better
Andrew Watson
Andrew Watson

Teachers certainly can benefit from background brain knowledge. It’s fascinating, for instance, to learn about the intricacies of neural network formation.

flashcard strategies

At the same time, we and our students often want practical classroom guidance. What exactly should we DO — and, in particular, what should we DO DIFFERENTLY?

For example: given the enthusiasm with which our students turn to flashcards, we should welcome any guidance on their best use.

Here’s a helpfully specific question: should our students use relatively small or relatively large stacks of cards?

Theory Meets Practice: Flashcard Strategies

Psychologists have a theory that should answer that question.

The “spacing effect” says that the same amount of practice spread out over time (“spaced“), rather than done all at once (“massed“), yields more learning.

If a student has — for example — only 5 flashcards in a pile, then she’ll encounter those words more frequently. On the other hand, if she has 20 flashcards in that  pile, then more time passes between each repetition.

5 flashcards = massing; 20 flashcards = spacing. Therefore, 20 flashcards ought to be better.

Nate Kornell, a practical researcher who writes with welcome clarity, tried just this experiment.

Students learned some word pairs with 4 piles of 5 flashcards each. They learned other word pairs with 1 pile of 20 flashcards.

Which flashcard strategy led to better recall the following day?

As the theory predicted, the larger pile of flashcards lead to better memory. In one trial, massed practice resulted in score of 38%. Spaced practice led to a score of 65%.

Crucially: students had the same amount of time to study the same number of words. Simply organizing those words one way (the big pile) rather than the other way (little pile) resulted in more learning.

A Paradox, and a Resolution

In Kornell’s study, larger stacks of flashcards yielded more learning for 90% of the students. And yet, even after they themselves had tried both approaches, 72% preferred the (ineffective) small stacks.

What gives? Why do they prefer ineffective flashcard strategies?

Kornell suspect that students prefer the study approach where they feel they’re making faster progress. Sadly, as happens quite often, the strategy that feels good in fact creates less learning.

Another example of this phenomenon: students typically prefer to reread passages rather than quiz themselves. Rereading doesn’t help them learn much, but it does make them feel more confident. (“I recognize that part! I must have learned it…”)

Flashcard Strategies: The Perfect Number

Given Kornell’s research, it’s tempting to think that students should always sort their flashcards into stacks of 20.

Instead of focusing on number, we should instead focus on relative challenge. The flashcard pile should be big enough so that

a) students feel stretched by the information they’re practicing, but

b) they don’t feel discouraged or overwhelmed.

That number will probably be higher than they would naturally choose. But it won’t be huge.

We might prefer to have more precise guidance than this. However, no one rule will apply equally well to all students.

The correct number of cards in a pile will be different in 2nd grade, 8th grade, and college. It will be different in subjects when students struggle and in subjects where they thrive. It will be different for flashcards that contain a lot of information and those with just a word or two.

Combining our teacherly experience with Kornell’s researcherly insight will lead to the best result we can hope for: flashcard strategies that promote optimum learning conditions.

Brains in the Classroom: Research-based Advice for Students
Andrew Watson
Andrew Watson

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.

Daring to Flip the Public Health Classroom
Andrew Watson
Andrew Watson

“Flipping the classroom” has been around long enough now to have its own Wikipedia page.

flipped classroom for adult learners

Proponents suggest that this strategy allows teachers to focus less on direct instruction and more on collaboration, problem solving, and application.

Critics respond that direct instruction offers many benefits. They also wonder if we are fooling ourselves by claiming that students learn deeply by watching videos at home.

Most discussion of flipped classrooms focuses on younger grades: its potential for teaching mitosis or long-division or the basics of circuitry.

What about adult learners? Can flipped classrooms help them learn?

Flipped Classroom for Adult Learners

A just-published study looks at a Principles of  Epidemiology course for grad students at Columbia University.

In 2015, instructors taught in the “traditional” way: 90 minutes of lecture, followed by 90 minutes of discussion.

In 2016, they flipped the classroom: “pre-recorded lectures [were] viewed outside the classroom setting (at home), and in-person classroom time [was] devoted to interactive exercises, discussion, or group projects.”

So: who learned more?

By practically every measure, it just didn’t make much difference.

For instance: at the midterm, the median grade in the traditional class was 94.0. In the flipped class, it was … 94.4.

On the final exam, the median traditional grade was — again — 94.0. The flipped class median was 92.5.

(If you look at mean grades instead of median, there is a slight — and statistically trivial — advantage for the flipped classroom.)

Whose Benefit?

Although these grad students didn’t learn any more epidemiology, they did prefer the flipped-classroom format. Why? Because it gave them greater flexibility in their otherwise over-scheduled and hectic lives.

If schools can promote the same amount of learning more conveniently, then that strategy feels like a real win.

At the same time, it’s not clear that this benefit transfers to younger learners.

  • Would they be as conscientious as these graduate students in watching the videos?
  • Are flipped-classroom self-tests typically as in-depth as the ones in this study? (That is: this study included excellent study questions — you can check them out on page 4.)
  • Are most students juggling work-life balance difficulties the way that these graduate students are?

In other words: flipped classrooms simplified schedules for these graduate students — even though they didn’t improve learning.

Whether or not that benefit transfers to K-12 students, however, depends a great deal on the specific circumstances that those students face.

Vital Resources in Psychology: the Best Research for Teachers
Andrew Watson

vital resources in psychologyOver the last ten years, I’ve found many articles and studies that I return to frequently.  Some summarize lots of research suggestions. Others explore particular questions with verve and clarity.

I hope you enjoy these as much as I do.

Vital Resources in Psychology: Big Lists

Our students often confuse PERFORMANCE (a high score on a test) with LEARNING (enduring knowledge and skill). Nick Soderstrom sorts through all kinds of evidence to help teachers distinguish between the two. Helpfully, he includes evidence for both physical and cognitive learning.

Learning versus Performance: An Integrative Review, by Nick Soderstrom and Robert Bjork

This comprehensive (!) article examines research behind ten well-known teaching practices: from underlining to retrieval practice. In each case, it looks at the quality of evidence. It then helps you choose those that fit your subject and your students best. (Danger: several sacred oxen gored here.)

Improving Students’ Learning with Effective Learning Techniques, by John Dunlosky (and many others)

The Science of Learning, by Deans for Impact

Vital Resources: Enlightening Studies

Regular readers of this blog know that “retrieval practice” helps students learn MUCH more effectively than simple review does. In brief: don’t have students reread a chapter. Have them quiz each other on the chapter. This kind of active recall fosters new learning. In this splendid study, a researcher, a teacher, and a principal move this finding out of the psychology lab and into the classroom.

The Value of Applied Research: Retrieval Practice Improves Classroom Learning and Recommendations from a Teacher, a Principal, and a Scientist, by Agarwal, Bain, and Chamberlain

In this marvelous study, researchers wonder if testing students on material before they’ve even seen it might help them ultimately learn it better. Here’s the fun part: when their first study suggests the answer is “yes,” they then repeat the study four more times in an attempt to prove themselves wrong.  Only when they can’t come up with any other explanations for their findings do they finally persuade themselves.
