Variability in information and spacing between learning, improves memory

“If you are trying to remember the new person’s name and something about them, like their favorite food, it is more helpful to repeat that same exact name-food pairing multiple times with spacing between each,” says a neuroscientist.

New experiments by neuroscientists and psychologists at the University of Pittsburgh and Temple University, both in the US, suggest varying what we study and spacing out our learning over time can both be helpful for retaining memories. 

The paper was published in the Proceedings of the National Academy of Sciences. 

“Lots of prior research has shown that learning and memory benefit from spacing study sessions out,” said co-author Benjamin Rottman, a psychologist at the University of Pittsburgh, in a press release.

By ‘spacing effect’, psychologists refer to not cramming information overnight, and instead ‘space’ it across a longer period. However, one important assumption here is that the information learnt doesn’t change. That is, you’re trying to memorize a diagram from a textbook at different intervals.

However, the new research wants to test the spacing effect with some of the information changed with time. The press release used an example of recalling features in a cafe across two different sittings, when the barista wasn’t the same.

The research question was: how adept is the brain then, at making associative connections and memory recall? 

The researchers conducted two experiments differentiated by the number of sittings through which they can absorb information. In both, participants were allowed to memorize two pairs of images – each pair consisting of an item and a scene.

One experiment will see participants sit through memorizing information in four sittings across a day, but repeated for 24 days with a test on the 25th day. However, in this case, one of the item-scene pairs will be repeated throughout the four sittings for 24 days. The other one, crucially however, will have some variation. Either the item remains the same, and the scene changes – or vice versa. 

The second experiment in contrast, will see all the memorization done in a single sitting, and tested the next day. 

The test is smartphone based – to test for their ‘associative’ learning, i.e. can they remember which scene a certain item corresponds to? Also, they test for a simple ‘item memory’, i.e. do they ever recall seeing the item before? 

The results did imply yet again that spaced learning was better than cramming. However, the most interesting result was how participants were better at recalling item-scene pairs with variations than they did for an item-scene pair that was flashing repeatedly before them across the sittings. 

What’s the main takeaway?

“Spacing only benefited memory for the pairs that were repeated exactly, and only if there were pretty long gaps, hours to days, between study opportunities,” said Rottman. “For example, if you are trying to remember the new person’s name and something about them, like their favorite food, it is more helpful to repeat that same exact name-food pairing multiple times with spacing between each.”

And there is some practical application this understanding can provide. 

“In theory our findings should be broadly relevant to different sorts of tasks, like remembering someone’s name and things about them, studying for a test and learning new vocabulary in a foreign language,” said Rotterman. 

However, there’s a caveat for school kids. “Because of how nuanced memory is,” Rotterman said, “it is hard to provide clear advice for things like studying for a test because the sort of material can be so different.”

Lead author Emily Cowan, a cognitive neuroscientist at Temple University, said, “Our work suggests that both variability and spacing may present methods to improve our memory for isolated features and associative information, respectively, raising important applications for future research, education and our everyday lives.”

The research was funded by the US’ National Science Foundation (NSF) and the National Institute of Health (NIH).

Imagine being dropped in a brand-new city where everyone speaks a different language. Some people grab a map and start drawing routes. Others listen intently to locals, some race into the streets to explore by doing, and a few quietly observe from a café, making notes. Which traveler are you? In the world of learning, discovering your “learning style” is like finding your unique superpower—the secret key to faster, deeper, more enjoyable learning.

How do you unlock your own learning?

Let’s dive into the Honey-Mumford and VAK (Visual, Auditory, Kinaesthetic) models—two of education’s most influential maps for personalizing the learning journey.

Why Learning Styles Matter (and Why They Change)

It’s important to realize learning preferences aren’t set in stone. Just as a traveler adapts to new cities, learners shift styles based on the challenge. Most of us lean toward one or two favourite modes, but flexibility is key. According to Peter Honey and Alan Mumford’s classic model, being able to “wear all four hats” is crucial for mastering new skills. If you stubbornly avoid certain ways of learning, you may unknowingly tie your own shoelaces together.

Here’s how the four Honey-Mumford learning styles look in action:

Activist: The daredevils of learning! Activists live for new experiences. They’re first to leap into workshops, group activities, and hands-on challenges. They learn best when they’re doing, discussing, and exploring.

Reflector: These learners are the wise owls. Quietly observing first, they watch from every angle, gathering information before jumping in. Their superpower? Drawing connections and insights from deep thinking.

Theorist: Think of the philosophers and scientists. Theorists want the “why” behind everything. They thrive on models, structures, and clear explanations, asking, “Does this make sense?” and “Is there a theory here?”

Pragmatist: These are the builders and fixers. Pragmatists want practical, real-world application. “How can I use this?” is their guiding question. They flourish when they’re solving problems and trying out ideas.

The Visual, Auditory, and Kinaesthetic Adventure

But wait—there’s more! According to neuro-linguistic programming and the globally popular VAK model, everyone navigates the world of knowledge in their own preferred “language”: seeing, hearing, or doing. Here’s how to spot yours:

Visual Learner: You see the world in pictures. Diagrams, charts, videos, and handouts light up your mind. If you sketch ideas or remember faces better than names, visual is your superpower.

Auditory Learner: Sound is your guide. You remember best what you hear—lectures, podcasts, discussions, even recording and replaying information. You may even talk aloud to “think.”

Kinaesthetic Learner: Your hands lead the way. You learn by doing. Whether painting, building, or physically working through problems, motion and touch fuel your brain.

So, How Do You Find Your Style?

No one is 100% one type. Like expert travelers, the best learners pack more than one compass. Educational researcher Niel Fleming expanded on these ideas, showing that all of us use a mix—sometimes favoring one “sense,” sometimes another. Being stuck with just one style can slow you down; flexibility makes the difference.

Educators, coaches, and students can all benefit by asking simple questions—”Do I remember better what I see, hear, or do?”—and using practical inventories from Honey, Mumford, or Fleming to discover strengths.

Want to unlock your learning superpower? Pay attention to how you most naturally enjoy, remember, and apply new information—and don’t be afraid to experiment with new learning adventures. Your secret strength might just surprise you.

What India’s Foundational Learning Crisis Is Really Telling Us About Math

 “They Can Count in the Market, But Not in the Classroom”: What India’s Foundational Learning Crisis Is Really Telling Us

Earlier this year, EdPublica reported on an unsettling truth emerging from a collaborative study by MIT and Indian education researchers: Indian children demonstrate impressive mathematical ability when navigating real-life situations—like calculating change in a vegetable market—but often fail when asked to solve similar problems in the classroom. The findings struck a chord, revealing a deep fracture between what children learn and how they learn it.

Now, new data from the government-backed PARAKH Rashtriya Sarvekshan 2024 confirms the broader scale of that crisis. Together, the two reports offer a sobering diagnosis of foundational learning in India—and an urgent call to rethink how education is delivered.

The transfer gap: Street-smart, classroom-stranded

In the February study we reported on, researchers observed that children who work in markets—some out of necessity—could perform complex mental arithmetic swiftly and accurately. But the same children struggled with formal school problems like structured division or textbook subtraction. Meanwhile, their peers in schools did well on written math tests but faltered when asked to apply the same concepts in spontaneous, real-life situations.

This disconnect isn’t just about math—it’s about transferability. What good is education if it doesn’t translate beyond the exam sheet?

PARAKH’s alarming snapshot

The Performance Assessment, Review, and Analysis of Knowledge for Holistic Development (PARAKH) is India’s new national assessment platform launched under the National Education Policy 2020. Managed by the NCERT in collaboration with CBSE and overseen by the Ministry of Education, PARAKH represents a shift away from traditional rote exams to competency-based evaluation.

Its first large-scale survey, conducted in December 2024 across 23 lakh students from Classes 3, 6, and 9, paints a picture that is both revealing and troubling.

In Class 3, only 55% of students could correctly sequence numbers up to 99 or perform simple addition and subtraction. By Class 6, just 53% had mastered multiplication tables up to 10. Math proficiency hovered at 46% overall. The pattern held across language and environmental studies as well.

Perhaps most alarming is the steady decline in foundational ability as students progress. What begins as a fragile grasp in Class 3 becomes a gaping void by Class 9.

Where you study matters

The data also revealed a curious twist: in Class 3, rural students marginally outperformed their urban peers in both math and language. But by Class 6 and 9, the urban students pulled ahead decisively. It suggests that whatever edge rural systems may offer in the early years is quickly lost due to resource constraints, poor infrastructure, or lack of academic support.

Meanwhile, central government-run schools—such as Kendriya Vidyalayas—consistently outperformed state-run and aided schools, particularly in mathematics. The gaps are not just between regions, but embedded within the structure of the system itself.

A system teaching at children, not with them

What both the MIT study and the PARAKH survey show is this: India’s education system, despite enormous progress in enrolment and infrastructure, still hasn’t solved the puzzle of meaningful learning. It teaches children how to arrive at the “right” answer on paper, but not how to reason, estimate, or solve problems in the real world.

This isn’t simply a curriculum issue—it’s pedagogical. Teachers often default to formulas and procedures, driven by syllabus completion and exam pressures. Conceptual understanding, critical thinking, and the space to make mistakes are rare in crowded classrooms with little support for differentiated learning.

Moving from numbers to nuance

To its credit, the Ministry of Education has recognized this crisis. The PARAKH framework is designed not just to assess but to inform change. Its next phase will involve teacher workshops, state- and district-level consultations, and detailed “health reports” of learning outcomes.

A country with one of the youngest populations in the world cannot afford a foundational crisis

But meaningful change will require more than data. It demands political will, sustained investment in teacher training, reduced pupil–teacher ratios, and a shift in classroom culture. Most of all, it requires a rethinking of what education is meant to do—not just pass students from one grade to the next, but prepare them for life.

The stakes couldn’t be higher

A country with one of the youngest populations in the world cannot afford a foundational crisis. Poor learning in early years compounds over time, leading to disengagement, dropout, and economic vulnerability. The students struggling to divide 96 by 8 today are tomorrow’s workforce—and the gaps in their learning will define the future of the nation.

If India wants to reap its much-discussed demographic dividend, it must invest in the one thing that can turn numbers into citizens, and citizens into leaders: deep, transferable learning.

Why the Arts Matter As Much As Science or Math

It is time to recalibrate. To reclaim the arts not as an extra, but as essential. Not just because they improve test scores—but because they improve lives.

Cultures have always been remembered by their art

A decade ago, a quiet crisis was unfolding in classrooms across the world—a crisis that continues to deepen. As the race to master STEM subjects quickens and strategic thinking becomes the gold standard of education, another essential pillar of learning is being pushed to the periphery: the arts.

In corridors where brush strokes once danced, and where theatre, music and storytelling ignited young minds, silence now lingers. Time and resources are reallocated. Arts periods shrink. Drama rooms gather dust. And with every such decision, we inch closer to a narrow, fragmented vision of what it means to educate a human being.

This cultural shift—palpable in countries like India—has been unsettling for educators and researchers who have long argued that art is not an elective luxury, but an essential ingredient of a well-rounded education. One such voice is that of Dr. Ellen Winner, a leading scholar of arts education, who warned in an interview with this author nine years ago: “When schools cut short the time reserved for the arts and redirect it to what they call ‘important’ subjects, they’re not just risking the future of potential artists. They’re losing out on the inventors, the empathetic leaders, the bold thinkers of tomorrow.”

Her message was clear. The arts do not merely decorate our cultural fabric—they weave it. Ellen Winner, a leading expert in the psychology of art, is Professor Emerita of Psychology at Boston College and a Senior Research Associate at Project Zero. She is the author of five books, including Invented Worlds (1982), The Point of Words (1988), Gifted Children (1996), How Art Works (2019), and An Uneasy Guest in the Schoolhouse (2022). She has also co-authored five influential titles in arts education, notably the Studio Thinking series and The Child as Visual Artist (2022).

More Than a Side Show

To ask, “What is the role of the arts in shaping a person?” is to ask what kind of world we want to build. For centuries, societies have turned to art not just for beauty, but for insight—for truth. From ancient cave paintings to Renaissance frescoes to street murals that challenge injustice today, art has never been a passive pursuit. It has always spoken, always provoked, always taught.

And yet, as Dr. Winner noted in our conversation, “The arts are the only school subjects constantly required to prove their usefulness.”

Imagine applying the same standard to history, or even to sports. Suppose a school coach claimed that playing baseball boosts students’ math scores due to statistical scoring. If researchers debunked the claim, would school boards eliminate baseball from the curriculum? Of course not. Because we instinctively know that athletics builds discipline, teamwork, resilience. That it matters. So why not extend the same understanding to the arts?

Beyond the Test Scores

It is tempting—and common—for policymakers to justify the arts in terms of their “spillover effects” on math or reading. And indeed, there is research that shows a correlation: students exposed to the arts tend to perform better across disciplines. But relying solely on this line of defense, Dr. Winner cautioned, is dangerous.

“Arts education must not be justified only by its secondary benefits,” she said. “If we do that, we grant permission for it to be cut whenever those benefits don’t show up clearly on a chart.”

The truth is, arts education offers something far deeper. It cultivates imagination, nurtures curiosity, and fosters emotional intelligence. It teaches us to live with ambiguity, to see from multiple perspectives, to create from chaos. These are not fringe skills. These are survival skills—in life, and in leadership.

A Legacy We Must Honour

The arts are not new. They have outlived empires. They have inspired revolutions. And they have told the stories of civilizations long after their rulers and battles were forgotten.

Dr. Winner, summarizing a lifetime of scholarship, told me this:

“Let’s bet on history. Cultures have always been remembered by their art. The arts predate the sciences. Education that excludes them is impoverished—and it leads to an impoverished society.”

We would never teach a child only numbers and grammar and send them out into the world. Yet when we sideline the arts, that’s exactly what we do. We deny them the tools to feel deeply, to question power, to imagine alternatives. We deny them the full experience of being human.

Looking ahead

This is not a plea for token inclusions. It is a call for equal footing. The arts must not sit at the kiddie table of education, forever proving their worth. They are the worth. Just as we revere science for its logic and discovery, we must revere art for its meaning and soul.

It is time to recalibrate. To reclaim the arts not as an extra, but as essential. Not just because they improve test scores—but because they improve lives.

Because in the end, we are remembered not for how efficiently we solved equations—but for the songs we sang, the stories we told, and the visions we dared to paint on the canvas of our times.
