Professor David Perkins likes to tell this story: Indian leader Mahatma Gandhi was getting on a train. One of his sandals slipped off and fell to the ground. The train was moving, and there was no time to go back. Without hesitation, Gandhi took off his second sandal and threw it toward the first. Asked by his colleague why he did that, he said one sandal wouldn’t do him any good, but two would certainly help someone else.
As Perkins writes in his new book, Future Wise, “People cherish the story as a marvelous example of a charitable act. And so it is, on a small scale, seizing a singular moment.”
But as he also points out, and as he told an audience at the Future of Learning institute held this past summer at the Ed School, it was more than that: It was also a knowledgeable act. By throwing that sandal, Gandhi had two important insights: He knew what people in the world needed, and he knew what to let go of.
Educators, Perkins says, need to embrace these same insights. They need to start asking themselves what he considers to be one of the most important questions in education: What’s worth learning in school?
What’s worth learning in school? It’s a question that students have been lobbing at teachers for years, in a slightly different form.
“In the back of the class, there’s that idly waving hand,” Perkins writes. “You’ve been teaching long enough to be pretty sure that hand is going to go up as soon as you got started on this topic, and so it does, with an annoying indolence. All right. You gesture toward the hand, Let’s hear it.
“The student: ‘Why do we need to know this?’”
As a teacher, Perkins says he hates that question. Teachers work hard at what they do, and the question is disrespectful. Yet, he admits, the question is actually a good one — an “uppity version” of what’s worth learning in school. (It’s also one he admits having asked once or twice himself.)
“When that ballistic missile comes from the back of the room, it’s a good reminder that the question doesn’t just belong to state school boards, authors of textbooks, writers of curriculum standards, and other elite,” he says. “It’s on the minds of our students.”
That’s why Perkins decided to devote an entire book, and many lectures and discussions, to how that question gets answered.
These days, he says we teach a lot that isn’t going to matter, in a significant way, in students’ lives. There’s also much we aren’t teaching that would be a better return on investment. As a result, as educators, “we have a somewhat quiet crisis of content,” Perkins writes, “quiet not for utter lack of voices but because other concerns in education tend to muffle them.” These other concerns are what he calls rival learning agendas: information, achievement, and expertise.
For starters, most education has become a mastery of a very large body of information, even if it’s not what Perkins calls lifeworthy — likely to matter, in any meaningful way, in the lives learners are expected to live.

“It’s nice to know things. I like to know things. You like to know things,” Perkins says. “But there are issues of balance, particularly in the digital age. The information in textbooks is not necessarily what you need or would like to have at your fingertips.” Instead, even though most people would say that education should prepare you for life, much of what is offered in schools doesn’t work in that direction, Perkins says. Educators are “fixated” on building up students’ reservoirs of knowledge, often because we default to what has always been done.
“Conventional curriculum is chained to the bicycle rack,” he says. “It sits solidly in the minds of parents: ‘I learned that. Why aren’t my children learning it?’ The enormous investment in textbooks and the cost of revising them gives familiar elements of the curriculum a longer life span than they might perhaps deserve. Curriculum suffers from something of a crowded garage effect: It generally seems safer and easier to keep the old bicycle around than to throw it out.”
As a result, “the lifeworthiness of the multitudinous facts and ideas in the typical curriculum is spotty,” he says. “It seems not to have been thought through very carefully.”
And simply having a vast reservoir of knowledge isn’t helpful if it’s not being used. “Knowledge is for going somewhere,” Perkins says, not just for accumulating. But too often, we tend to focus on short-term successes — scoring well on a quiz, acing a spelling test. Unfortunately all of that test knowledge, all of that accumulated knowledge we thought was worth knowing, becomes useless if not used.
“The hard fact is that our minds hold on only to knowledge we have occasion to use in some corner of our lives,” Perkins writes. “Overwhelmingly, knowledge unused is forgotten. It’s gone.”
Here’s where, during the Future of Learning session, Perkins asked the audience to think about something they learned during the first dozen years of schooling that really matters in their lives today, beyond basics like learning to read and not including specialty professional skills.
“The frightening thing when I have these conversations is how hard it is for people to answer,” he says. “I find that frightening. It also says a lot about the current state of education.”
Take mitosis, the process of cell division. During the Future session, he asked everyone in the audience — hundreds of people — to raise their hands if they had studied mitosis in high school. Pretty much every hand went up. He asked how many people remember, basically, what it is. About half went up. He then asked how many have used their knowledge of went up.
Perkins acknowledged that he personally finds mitosis fascinating and stressed that with learning, there should always be room for passion, “but in terms of generalized education and what everyone should learn, something like mitosis doesn’t score well.”
Just as educators are pushing students to build a huge reservoir of knowledge, they are also focused on having students master material, sometimes at the expense of relevance. This happens, for example, with the achievement gap. While Perkins is quick to say that the achievement gap is a highly important problem that should be taken seriously, in general, he says, “achievement” is about mastering a topic and less about providing lifeworthy content. The achievement gap asks if students are achieving X. Instead, it might be more useful to look at the relevance gap, which asks if X is going to matter to the lives students are likely to lead.
“If X is a good mastery of reading and writing, both questions earn a big yes!” Perkins says. “Skilled, fluent, and engaged reading and writing mark both a challenging gap and a high-payoff attainment. That knowledge goes somewhere. However, if X is quadratic equations, the answers don’t match. Mastering quadratic equations is challenging, but those equations are not so lifeworthy.” Perkins says we can fill in X with thousands of topics that make up the typical curriculum, such as geography. Students are drilled to remember state capitals and major rivers and rewarded as “achieving” when they score well. And while it’s nice and sometimes useful to know those things, Perkins argues that instead, knowing how the location of rivers and harbors and other features of the land have been shaped and continue to shape the course of history offers more in terms of lifelong usefulness — more so than “a bag full of facts. All that talk about achievement leaves little room for discussing what’s being achieved.”

And then there’s what Perkins calls “the Holy Grail” of learning in school: becoming an expert. The typical math curriculum is a good example of how we want learners to move toward expertise in a subject, with little regard for usefulness. Arithmetic leads to algebra, including many “hardly used twists and turns” of advanced algebra, then to geometry and calculus, “an entire subject that hardly anyone ever uses,” Perkins writes.
Unfortunately, if someone questions whether this expertise serves students well and instead suggests more life-relevant topics, Perkins says the common reaction is: “We’re sacrificing rigor!” But that doesn’t have to be the case. Instead of building during the first 12 years of schooling toward expertise in an advanced topic like calculus that hardly ever comes up in our lives, Perkins says students can instead become “expert amateurs” in something like statistics — a rigorous topic that is also used in daily life. In fact, expert amateurism works great, he says, in most of what we do in our lives — raising children, filing taxes, appreciating art, understanding insurance rates, or dealing with our own health care.
Perkins is very clear that expertise in a specific field is not bad; in fact, he encourages it and assumes it will happen at the college or university level. But he advocates that in today’s world, younger students need to first master the fundamentals of key learning and then decide where they want to specialize.
So we come back to the question: What is worth learning? In his book, Perkins promises that he is not going to answer that question, at least not in a tidy way. There’s no list of 1,000 things we must know or teach. Perkins says there would be no way to create a definitive list because there are lots of things worth learning at any given time or for a specialized career or even simply because we enjoy learning.
Instead, he does know that the encyclopedic approach to learning that happens in most schools that focuses primarily on achievement and expertise doesn’t make sense.
“The fixation on the heap of information in the textbooks is itself part of the problem because the world we are educating learners for is something of a moving target,” he says.
Historically, the first 12 or so years of schooling have focused on educating for the known, “the tried and true, the established canon,” he writes. “This made very good sense in the many periods and places where most children’s lives were likely to be more or less like their parents’ lives. However, wagering that tomorrow will be pretty much like yesterday does not seem to be a very good bet today. Perhaps we need a different vision of education, a vision that foregrounds educating for the unknown as much as for the known.”
And to do that, Perkins says we need to rethink what’s worth learning and what’s worth letting go of — in a radical way.
“We do kind of need to blow up the system and start fresh,” he says. “Well, maybe not blow up the whole thing, but at least some corners.”
One of those corners is the drive to educate through high-stakes testing, he says.
“It’s clear that NCLB has not worked well,” with pressures on teachers and students, sometimes leading to instances of cheating and maneuvering. With high-stakes testing, he says, there’s a fixation on “summative” versus “formative” assessment — evaluating students’ mastery of material with exams and final projects (achievements) versus providing ongoing feedback that can improve learning. “You end up shooting for the Big contest, the Big test, at the end of the year,” he says. “It’s a distortion.” As a result, “students are asked to learn a great deal for the class and for the test that likely has no role in the lives they will live — that is, a great deal that simply is not likely to come up again for them in a meaningful way.”

Perkins stresses that he isn’t taking a stance against assessment, which he says is critical for learning. Instead, “it’s more about how assessment is made. This is a vote for a richer form of achievement.”
To be fair, he says, the assessment “game” as it’s usually played in education seems perfectly reasonable — at first. Tests “are socially pretty efficient. You can distribute them widely and score them efficiently,” he says. “We give those tests. We evaluate those tests. But that makes for shallow learning and understanding. … You cram to do well on the test but may not have the understanding. It unravels.”
Instead, we should be moving away from an understanding of something — the information on the test, the list of state capitals — to an understanding with something. With the latter, he says, students are able to then make connections to other things. For example, rather than just learning facts about the French Revolution, students should learn about the French Revolution as a way to understand issues like world conflict or poverty or the struggle between church and state. Without those connections, Perkins says he’s not surprised that so many people have trouble naming things they learned early on that still have meaning today or that disengaged students are raising their hands, asking why they need to know something.
“And students are completely right,” he says. “First-graders are very interested [in school], but over time, engagement slides and slides. There are often multiple reasons why, but one is that they don’t see the relevance of what they are learning. They don’t see how it serves their lives.”
Growing up in Farmington, Maine, a small town with just under 5,000 residents, Perkins remembers it feeling safe and peaceful, a great place to come of age. He also remembers being bored with school through eighth grade.
“I got excited in high school when I encountered a range of topics treated at a higher level,” he says. But, he acknowledges, he was probably unique. “I was lucky, I think, in that I’m not so much the kind of person that Future Wise was written for. I like a lot of knowledge for knowledge’s sake. Algebra, history — I can really get into those things. I don’t have to ask myself how is this going to be enlightening my life.”
Still, despite his own experience, he says that in the bigger picture of learning, we need to remember Gandhi.
“As the train started up and Gandhi tossed down his second sandal, he showed wisdom about what to keep and what to let go of,” Perkins says. “Those are both central questions for education as we choose for today’s learners the sandals they need for tomorrow’s journey.”
