Equity made Estonia an educational front runner
Estonia has combined a belief in learning with equal-access technology to create one of world's best education systems.
- Estonia became a top performer in the most recent PISA, a worldwide study of 15-year-old students' capabilities in math, reading, and science.
- PISA data showed that Estonia has done remarkably well in reducing the gap between a student's socioeconomic background and their access to quality education.
- The country's push toward providing equal-access to learning technology is a modern example of the culture's dedication to equity in education.
As I performed my interviews for this article, one fact was made abundantly clear: Estonians aren't ones to engage in lavish praise and pat-on-the-back congratulations. A far more self-critical culture, they find comfort forgoing the small talk, getting to work, and honing in on areas to improve. But one area where Estonians will simply have to grit and bare the praise is in discussing their education system. Smaller than West Virginia and with a population of 1.3 million, this Baltic state has developed one of the world's best education systems as assessed by the Programme for International Student Assessment (PISA) results.
PISA is the Organization for Economic Cooperation and Development's (OECD) triennial study that measures the reading, mathematics, and science abilities of 15-year-olds across the world. Talks of PISA tend to focus on educational powerhouses such as Finland, Singapore, and Korea, but those looking closely have been noticing Estonia's ascent throughout the years. It began in 2006, and despite a small dip in 2009, the country's scores continued upward in 2012 and 2015.
By 2018, the most recent PISA study, Estonia became Europe's number one performing country and one of the best in the world. Its students placed fifth in reading, eighth in math, and fourth in science, with mean scores in each that were well above the mean. The only education departments to outperform Estonia's were Singapore and a few of China's distinct economic areas, such as Beijing, Shanghai, and Macau.
Such a cohort may make the reason for such scores obvious. Like Singapore and Shanghai, Estonia is both small and relatively affluent; such education departments simply spread out their resources across fewer students. But PISA's data doesn't support this reasoning. While socioeconomic background is an important predictor of academic success, it doesn't play out that more money equals better education. In fact, according to PISA data, Estonia's per student expenditure was 30 percent lower than the OECD average. Conversely, the United States handily outspends many other countries but receives middling PISA scores for its investment.
Then what explains Estonia's ascent? That's an answer that requires untangling a myriad of cultural, social, and historical factors that interconnect in ways difficult to untangle. But one factor stands out. A cultural mindset centered only on excellence in education but the drive to give students equal access to that education.
Estonia's cultural heirloom

The belief in education's value is ingrained within Estonian culture. As Mailis Reps, the Estonian Minister of Education and Research, told me in an interview, it's an ethos handed down generation to generation, like a cultural heirloom.
"Many generations have had to start from zero all over again. Let it be the war, the regimes, economic reforms, people being deported, people losing their families, or changes to the system," Reps said. "So, education was something that was always given, generation to generation. There's a very strong cultural belief that education is the only thing you cannot take away from a person."
Because education is a constitutional right, Reps informed me, state and local governments ensure that primary education is available to everyone. Lunches, textbooks, transportation, and study materials are provided gratis, with extracurricular activities subsidized so fees remain low. Local municipalities also subsidize pre-primary education. They maintain a social allowance so fees are tied on a parent's financial situation. Parents enduring economic hardships or temporary setbacks can send their little ones to preschool free of charge, while more financial stable families pay a small fee. And even that fee remains small—Reps says it is no more than €91 (about $107).
Under such a comprehensive system, many children start their education careers young, as early as 15 months old. Because pre-primary isn't compulsory, parents have more latitude over how their children attend school: half days, a few days a week, etc. By kindergarten, Estonia has a 91 percent attendance rate. Primary attendance is close to universal.
That system may sound expensive, and like any education system, it takes its share of GDP. But as mentioned, it's not simply a matter of dollars spent. According to the National Center for Education Statistics, in 2016 the United States spent $13,600 per full-time-equivalent student in elementary and secondary education. The OECD average that same year was $9,800. Estonia spent $7,400.
"In many countries, the school's socioeconomic context influences the kind of education children are acquiring, and the quality of schooling can shape the socioeconomic contexts of schools," Andreas Schleicher, the OECD's director for the Directorate of Education and Skills, writes in his assessment of PISA 2018's data. "The result is that in most countries, differences in education outcomes related to social inequalities are stubbornly persistent, and too much talent remains latent."
But despite relatively modest spending, that's less true in Estonia. According Schleicher's assessment, 20 percent of disadvantaged boys did not attain minimum proficiency in reading in all countries except three. Estonia was one of those three. It stood as one of 14 countries in which disadvantaged students have at least a one-in-five chance of having high-achieving schoolmates, a ratio that corresponds to reduced social segregation. And the country joined Australia, Canada, Ireland, and the United Kingdom in having more than 13 percent of its disadvantaged students demonstrate academic resilience, a metric that measures proficient educational outcomes in the face of adversity.
These data point to a weak relationship between student performance and socioeconomic background, a sign that Estonia has lessened the gap between a student's personal situation and their access to quality education.
A Tiger Leap forward
Fourth-grade students learn computer skills in elementary school.
A crucial example of Estonia's dedication to equity can be seen in how it wove digital technology into the learning fabric. In the last two decades, Silicon Valley has had a commanding influence in how we approach and access education, but for many countries, the push toward always-accessible, always-on education hasn't ameliorated many systemic inequalities.
Consider the United States. The U.S. finances schools through local property taxes or federal grants tied to test scores and attendance rates. This leaves schools in well-to-do districts with a lion share of funding and resources. Such lopsided endowments, as noted a 2018 report by the U.S. Commission on Civil Rights, "harm students subject to them" and are "fundamentally inconsistent with the American ideal of public education operating as a means to equalize life opportunity." An inconsistency that the Supreme Court has defended as perfectly in keeping with the U.S. Constitution.
This legacy inequality left many low-income neighborhoods facing another disadvantage at the turn of the century: a lack of access to technology. That reality became starkly apparent in the COVID-19 pandemic. Data from the U.S. Census Bureau suggests that as schools closed, "1 in 10 of the poorest children in the U.S. has little or no access to technology" for learning. For children being raised in a household earning less than $25,000 a year, roughly ten percent have no access to the internet or digital learning devices.
Conversely, Estonia has made internet access available to all students. In the late 1990s, after its independence from Russia, Estonia initiated Tiger Leap. The program invested heavily in building and developing infrastructure for the e-revolution. The push moved many social programs online, such as taxes, voting, and health records, and schools were updated for internet access, computer labs, and the then-latest technologies.
Today, Estonia has made digital literacy a key competency required in its educational outcomes. Learning materials, such as textbooks and assessments, must be available for free in a digital format (known as the e-schoolbag). Even schools in remote areas enjoy access to high-speed internet.
That may sound concerning to parents worried that today's technology has reduced learning to the solitude of screens and mental cubicles. But the Estonian government only provides access to the tools and ensures they work. Schools and teachers have broad autonomy in determining when and how to use them. That is, after all, their expertise.
"We have never forced our teachers to use it, but we have celebrated if they do so," Reps said. "This is one of the things that I advocate a lot. Provide them the possibility, build them the infrastructure, the quality needs to be there. Because if you start downloading and it doesn't work, no young person accepts it."
Teachers of young students, for example, may forgo technological solutions in favor of more analog approaches to develop motor and social skills. Meanwhile, secondary education may lean heavier on online assessments to prepare students for a tech-focused workforce.
Unlike Silicon Valley's push into the U.S. education system—a seeming bid to capitalize as much on student's learning time as their free time—Estonia prefers a more Goldilocks strategy. As Gunda Tire, Estonia's PISA National Project Manager, told me in an interview: "If you look at PISA data about education systems that use a lot of technology, if they use it very extensively, they have lower scores. If they don't use it at all, they also have lower scores. The big challenge is to find the balance."
As we've learned during the pandemic, that's a balance that shifts with circumstance, but by distributing the tools and infrastructure broadly, Estonia has been able to keep its footing. Reps estimates that before the COVID-19 shutdowns, approximately 14 percent of schools regularly used the available digital textbooks. Most preferred the physical counterpart.
But because the digital option was available for ever school, they were able to quickly pivot to a 100-percent use rate. Additionally, years of prioritizing computer literacy development helped teachers gain competency in digital learning tools, and a civil social push identified at-need children to equip them with the devices necessary to learn remotely. As Mart Laidmets, Estonia's secretary general of the Ministry of Education and Research, said in a roundtable on the subject, it looked as though the country had "been preparing for such a crisis for 25 years."
What can we learn from Estonia's success?
While Estonia may not spend as much on a dollar-to-dollar basis, the country has created immense valuable in its system by spreading the educational wealth. Part of that achievement stems from removing barriers to primary education and fostering equal-access to learning technology; however, those are simply examples of the principle of equity at work. Others include well-educated teachers, even at the pre-primary level; granting schools broad autonomy to adapt the national curriculum to suit local and cultural needs; and maintaining at-school support centers so students have access to mentors, psychologists, special needs teachers, and anti-bullying resources. The list goes on.
"The success of any system is sort of like a puzzle," Tire said. "You have to have many pieces and fit them in properly, or you won't see the whole picture."
Is there room for improvement? Of course! Just ask any Estonian. Tire told me that recent PISA data showed a discrepancy in the results between the country's Estonian-speaking students and its Russian-speaking ones. They are looking into the reason for that gap and how to raise scores across the board. When asked the same question, Reps pointed to improving the country's vocational-track education, the integration of practical skills into gymnasium, and research into personalized learning.
When asked what other countries could takeaway from Estonia's example, my interviewees were more cautious. As Reps rightly points out, "Education is so culturally and historically tied. It's very difficult to copy something, and I would be careful to tell any country to copy the Estonian model."
She did offer some facets for consideration, though. She recommends that systems never look at a child as a problem to solve. Instead, it should look to ameliorate issues in their background or experiences. Even though education systems can be expensive, they should always be child-friendly and dedicated toward their growth. Digital technology doesn't create equality de facto; it must be accessible to all. And trust your teachers. "They are amazing human beings. They come to teach; they want to give their best; they want to help their pupils."
In my own research into Estonia's education system, its history, and its successes, I would humbly add one more: Foster a culture that values education and assures its available to everyone.

Geologists discover a rhythm to major geologic events.
- It appears that Earth has a geologic "pulse," with clusters of major events occurring every 27.5 million years.
- Working with the most accurate dating methods available, the authors of the study constructed a new history of the last 260 million years.
- Exactly why these cycles occur remains unknown, but there are some interesting theories.
Our hearts beat at a resting rate of 60 to 100 beats per minute. Lots of other things pulse, too. The colors we see and the pitches we hear, for example, are due to the different wave frequencies ("pulses") of light and sound waves.
Now, a study in the journal Geoscience Frontiers finds that Earth itself has a pulse, with one "beat" every 27.5 million years. That's the rate at which major geological events have been occurring as far back as geologists can tell.

According to lead author and geologist Michael Rampino of New York University's Department of Biology, "Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle, suggesting that these geologic events are correlated and not random."
The new study is not the first time that there's been a suggestion of a planetary geologic cycle, but it's only with recent refinements in radioisotopic dating techniques that there's evidence supporting the theory. The authors of the study collected the latest, best dating for 89 known geologic events over the last 260 million years:
- 29 sea level fluctuations
- 12 marine extinctions
- 9 land-based extinctions
- 10 periods of low ocean oxygenation
- 13 gigantic flood basalt volcanic eruptions
- 8 changes in the rate of seafloor spread
- 8 times there were global pulsations in interplate magmatism
The dates provided the scientists a new timetable of Earth's geologic history.

Putting all the events together, the scientists performed a series of statistical analyses that revealed that events tend to cluster around 10 different dates, with peak activity occurring every 27.5 million years. Between the ten busy periods, the number of events dropped sharply, approaching zero.
Perhaps the most fascinating question that remains unanswered for now is exactly why this is happening. The authors of the study suggest two possibilities:
"The correlations and cyclicity seen in the geologic episodes may be entirely a function of global internal Earth dynamics affecting global tectonics and climate, but similar cycles in the Earth's orbit in the Solar System and in the Galaxy might be pacing these events. Whatever the origins of these cyclical episodes, their occurrences support the case for a largely periodic, coordinated, and intermittently catastrophic geologic record, which is quite different from the views held by most geologists."
Assuming the researchers' calculations are at least roughly correct — the authors note that different statistical formulas may result in further refinement of their conclusions — there's no need to worry that we're about to be thumped by another planetary heartbeat. The last occurred some seven million years ago, meaning the next won't happen for about another 20 million years.
Research shows that those who spend more time speaking tend to emerge as the leaders of groups, regardless of their intelligence.
- A new study proposes the "babble hypothesis" of becoming a group leader.
- Researchers show that intelligence is not the most important factor in leadership.
- Those who talk the most tend to emerge as group leaders.
If you want to become a leader, start yammering. It doesn't even necessarily matter what you say. New research shows that groups without a leader can find one if somebody starts talking a lot.
This phenomenon, described by the "babble hypothesis" of leadership, depends neither on group member intelligence nor personality. Leaders emerge based on the quantity of speaking, not quality.
Researcher Neil G. MacLaren, lead author of the study published in The Leadership Quarterly, believes his team's work may improve how groups are organized and how individuals within them are trained and evaluated.
"It turns out that early attempts to assess leadership quality were found to be highly confounded with a simple quantity: the amount of time that group members spoke during a discussion," shared MacLaren, who is a research fellow at Binghamton University.
While we tend to think of leaders as people who share important ideas, leadership may boil down to whoever "babbles" the most. Understanding the connection between how much people speak and how they become perceived as leaders is key to growing our knowledge of group dynamics.
The power of babble
The research involved 256 college students, divided into 33 groups of four to ten people each. They were asked to collaborate on either a military computer simulation game (BCT Commander) or a business-oriented game (CleanStart). The players had ten minutes to plan how they would carry out a task and 60 minutes to accomplish it as a group. One person in the group was randomly designated as the "operator," whose job was to control the user interface of the game.
To determine who became the leader of each group, the researchers asked the participants both before and after the game to nominate one to five people for this distinction. The scientists found that those who talked more were also more likely to be nominated. This remained true after controlling for a number of variables, such as previous knowledge of the game, various personality traits, or intelligence.

In an interview with PsyPost, MacLaren shared that "the evidence does seem consistent that people who speak more are more likely to be viewed as leaders."
Another find was that gender bias seemed to have a strong effect on who was considered a leader. "In our data, men receive on average an extra vote just for being a man," explained MacLaren. "The effect is more extreme for the individual with the most votes."
The great theoretical physicist Steven Weinberg passed away on July 23. This is our tribute.
- The recent passing of the great theoretical physicist Steven Weinberg brought back memories of how his book got me into the study of cosmology.
- Going back in time, toward the cosmic infancy, is a spectacular effort that combines experimental and theoretical ingenuity. Modern cosmology is an experimental science.
- The cosmic story is, ultimately, our own. Our roots reach down to the earliest moments after creation.
When I was a junior in college, my electromagnetism professor had an awesome idea. Apart from the usual homework and exams, we were to give a seminar to the class on a topic of our choosing. The idea was to gauge which area of physics we would be interested in following professionally.
Professor Gilson Carneiro knew I was interested in cosmology and suggested a book by Nobel Prize Laureate Steven Weinberg: The First Three Minutes: A Modern View of the Origin of the Universe. I still have my original copy in Portuguese, from 1979, that emanates a musty tropical smell, sitting on my bookshelf side-by-side with the American version, a Bantam edition from 1979.
Inspired by Steven Weinberg
Books can change lives. They can illuminate the path ahead. In my case, there is no question that Weinberg's book blew my teenage mind. I decided, then and there, that I would become a cosmologist working on the physics of the early universe. The first three minutes of cosmic existence — what could be more exciting for a young physicist than trying to uncover the mystery of creation itself and the origin of the universe, matter, and stars? Weinberg quickly became my modern physics hero, the one I wanted to emulate professionally. Sadly, he passed away July 23rd, leaving a huge void for a generation of physicists.
What excited my young imagination was that science could actually make sense of the very early universe, meaning that theories could be validated and ideas could be tested against real data. Cosmology, as a science, only really took off after Einstein published his paper on the shape of the universe in 1917, two years after his groundbreaking paper on the theory of general relativity, the one explaining how we can interpret gravity as the curvature of spacetime. Matter doesn't "bend" time, but it affects how quickly it flows. (See last week's essay on what happens when you fall into a black hole).
The Big Bang Theory
For most of the 20th century, cosmology lived in the realm of theoretical speculation. One model proposed that the universe started from a small, hot, dense plasma billions of years ago and has been expanding ever since — the Big Bang model; another suggested that the cosmos stands still and that the changes astronomers see are mostly local — the steady state model.
Competing models are essential to science but so is data to help us discriminate among them. In the mid 1960s, a decisive discovery changed the game forever. Arno Penzias and Robert Wilson accidentally discovered the cosmic microwave background radiation (CMB), a fossil from the early universe predicted to exist by George Gamow, Ralph Alpher, and Robert Herman in their Big Bang model. (Alpher and Herman published a lovely account of the history here.) The CMB is a bath of microwave photons that permeates the whole of space, a remnant from the epoch when the first hydrogen atoms were forged, some 400,000 years after the bang.
The existence of the CMB was the smoking gun confirming the Big Bang model. From that moment on, a series of spectacular observatories and detectors, both on land and in space, have extracted huge amounts of information from the properties of the CMB, a bit like paleontologists that excavate the remains of dinosaurs and dig for more bones to get details of a past long gone.
How far back can we go?
Confirming the general outline of the Big Bang model changed our cosmic view. The universe, like you and me, has a history, a past waiting to be explored. How far back in time could we dig? Was there some ultimate wall we cannot pass?
Because matter gets hot as it gets squeezed, going back in time meant looking at matter and radiation at higher and higher temperatures. There is a simple relation that connects the age of the universe and its temperature, measured in terms of the temperature of photons (the particles of visible light and other forms of invisible radiation). The fun thing is that matter breaks down as the temperature increases. So, going back in time means looking at matter at more and more primitive states of organization. After the CMB formed 400,000 years after the bang, there were hydrogen atoms. Before, there weren't. The universe was filled with a primordial soup of particles: protons, neutrons, electrons, photons, and neutrinos, the ghostly particles that cross planets and people unscathed. Also, there were very light atomic nuclei, such as deuterium and tritium (both heavier cousins of hydrogen), helium, and lithium.
So, to study the universe after 400,000 years, we need to use atomic physics, at least until large clumps of matter aggregate due to gravity and start to collapse to form the first stars, a few millions of years after. What about earlier on? The cosmic history is broken down into chunks of time, each the realm of different kinds of physics. Before atoms form, all the way to about a second after the Big Bang, it's nuclear physics time. That's why Weinberg brilliantly titled his book The First Three Minutes. It is during the interval between one-hundredth of a second and three minutes that the light atomic nuclei (made of protons and neutrons) formed, a process called, with poetic flair, primordial nucleosynthesis. Protons collided with neutrons and, sometimes, stuck together due to the attractive strong nuclear force. Why did only a few light nuclei form then? Because the expansion of the universe made it hard for the particles to find each other.
What about the nuclei of heavier elements, like carbon, oxygen, calcium, gold? The answer is beautiful: all the elements of the periodic table after lithium were made and continue to be made in stars, the true cosmic alchemists. Hydrogen eventually becomes people if you wait long enough. At least in this universe.
In this article, we got all the way up to nucleosynthesis, the forging of the first atomic nuclei when the universe was a minute old. What about earlier on? How close to the beginning, to t = 0, can science get? Stay tuned, and we will continue next week.
To Steven Weinberg, with gratitude, for all that you taught us about the universe.
