At this point, everyone who cares about education policy at all has probably, or pretends to have, and is aware that there is a correct way to teach children to read and also a different way that dominated education schools for a generation. There are now many state- and city-level pushes to institute correct instructional practices grounded in 鈥渢he science of reading,鈥� and the main question is about rather than what the practice should look like.

I think it鈥檚 less understood that this specific fiasco in early literacy was downstream of the education theory world鈥檚 broader turn against explicit instruction.

This has always struck me as a bit odd because 鈥渢eaching things to people鈥� is of course a human endeavor that exists outside the context of 鈥渂eing a K-12 teacher.鈥� And it seems to me that outside of school, explicit instruction is the dominant instructional method.

I once took a knife skills class, and they just show you how to chop an onion. You trim the stem. You cut in half from end to end. You peel the skin. You make vertical slices that leave the root intact, then horizontal slices, and then another set of vertical slices across the third dimension. Here鈥檚 a from 鈥淭he Art of Manliness.鈥� There are also many videos demonstrating this method.

There is a specific, correct way to do this, and part of learning to cook is being told how to do it.

A person with excellent spatial reasoning could probably figure this out from first principles given an onion and a knife. But the normal way to learn to chop is to be explicitly shown. Chopping a bell pepper is a little different, but you can be shown that, too. You don鈥檛 just give people knives and tell them to experience the joy of chopping. Because even though some people really love cooking and find it to be an amazing avenue for self-expression, it鈥檚 also useful to know how to chop vegetables, and the best way to get from zero to vaguely competent is to be taught the proper way to do it and then given the opportunity to practice.

Education school theorists, for reasons that are disputed, seem to dislike this idea.

From Jean-Jacques Rousseau鈥檚 鈥淓mile鈥� to Paulo Freire鈥檚 鈥淭he Pedagogy of the Oppressed,鈥� a long tradition in the field mashes up romanticism with left-wing politics and sentimentality about the point of school to suggest that there鈥檚 some other, secretly better way of teaching things to beginners than just literally teaching them.

But while there鈥檚 certainly more to life than explicitly instructing novices in the basics, across a huge range of domains, that really is the foundation of knowledge. You need to master sounding words out before you can analyze literature, and it鈥檚 extremely helpful to have your times tables and other basic math facts memorized so that your brain can think about more elevated mathematical questions without constantly tripping over the calculations.

Learning is fundamental

The association between fuzzy educational practices and left-wing politics strikes me as rather contingent.

The Soviet Union and its satellite states in Eastern Europe, for example, all ran school systems that would read as strikingly 鈥渞ight-wing鈥� by American standards (of course, these regimes weren鈥檛 exactly defunding the police, either). Antonio Gramsci also about elementary education.

But in the contemporary West, a constellation of odd pedagogical notions has a very particular ideological alignment.

The influential Stanford education professor Jo Boaler the habit of 鈥減resent[ing] mathematics procedurally, as sets of steps to memorize and apply鈥� and 鈥渢imes table repetition, practice, and timed testing is unnecessary and damaging.鈥� As early as 2013, she was that there鈥檚 too much 鈥渄rill and practice鈥� in math education.

Efforts to stigmatize the basic building blocks of teaching and learning have at times taken pretty loopy turns. There was a big national news story five years ago when an outfit called Equitable Math was arguing that focusing on getting the right answer was.

In their less loopy forms, though, the ideas flying under the banner of 鈥渄iscovery,鈥� 鈥渃onstructivist,鈥� or 鈥渋nquiry-based鈥� math offer high-minded justifications about allowing children to unearth the deeper truths of the mathematical world for themselves through play and free inquiry rather than by drilling algorithmic procedures for solving problems.

There is doubtless room for this sort of inquiry, especially when you want more advanced students to achieve a deeper understanding. But instruction with minimal guidance simply does not work ().

And while there鈥檚 something to the concept of 鈥溾�� versus simply telling kids how to solve the problem, it can also easily become an excuse for not actually teaching kids how to do the math.

Practice makes perfect

In particular, I would say that Boaler鈥檚 narrative about the perils of over-drilling seems to come from a counterfactual universe in which everyone is learning basic math well and then stalling out. That does happen sometimes! Probably all of us who鈥檝e learned math at some point hit a point at which the material is just too hard for us. And the question of how to keep people motivated to work through the pain and genuinely get as far as they can is interesting.

But the actual situation in American math education is that in 2019, just 50% of eighth graders taking the National Assessment of Educational Progress math assessment got this word problem correct, and by 2022,.

This is just not that deep of a question. Apparently, a very large share of American eighth graders cannot reliably do division. If you present mathematics procedurally, as sets of steps to memorize and apply, then I think kids are going to be able to answer this question.

Beyond galaxy brain ideology, hostility to explicit instruction seems downstream of labor union politics.

Teachers鈥� unions in the United States, like labor unions generally, favor salary structures that are heavily weighted toward the interests of the most senior union members. As a result, they push for compensation schemes that are heavily backloaded (generous pensions and health plans relative to actual salaries) and where salaries are based pretty strictly on seniority rather than on teaching skill, outside labor-market options, or compensating differentials for harder assignments.

It鈥檚 not unusual for public-sector collective-bargaining agreements to have undesirable features for no good reason (see the that are being). But K-12 education is unusual in that it鈥檚 the subject of much more public discussion 鈥� parents understandably have a lot of opinions 鈥� so union leaders can鈥檛 just defend their position by saying, 鈥淲ell, that鈥檚 how our members want it.鈥�

They need to come up with reasons for why the system should work the way their most senior members want it to work.

This has meant, over the course of my career, a tremendous amount of effort to discredit the idea of giving students standardized tests as a way of measuring their subject matter competency. There鈥檚 been a lot of emphasis on the idea that but also a broader effort to discredit the idea that teachers whose students improve on tests are doing a good job of teaching.

As long as I鈥檝e been covering these issues, union leaders have been raising the specter of 鈥溾�� (that鈥檚 from 2003) as a classroom practice. The National Education Association is constantly warning of the dangers of 鈥�,鈥� Randi Weingarten, and I think it鈥檚 just remarkably obfuscatory. One can, of course, imagine a classroom that is overly focused on repetition and rote memorization relative to what I would consider an educational ideal.

But in a country full of classrooms like that, more than 44% of students could accurately answer the ribbon question.

You can literally just teach things

An interesting fact about modern human life is that while 鈥渆ducation鈥� happens within a specific set of institutions, 鈥渓earning things鈥� occurs in a much broader set of contexts. And I think it鈥檚 striking that in non-school contexts, we invariably rely quite a bit on explicit instruction.

For example, I sometimes like to impress children with my limited-but-impressive-to-kids ability to juggle.

Invariably, when a kid tries to copy what they just saw, they can鈥檛 execute even a single toss. There is no amount of exploratory tossing of balls that will lead most children to figure out how to juggle 鈥� they鈥檒l get frustrated and give up.

Yet learning to juggle is actually pretty easy. You need to start with three scarves and do. When you can do that really well (鈥渄rill and kill鈥�), you can try it with a set of balls. If you get good at balls (drill and kill again), you can start tossing around apples or stuffed animals or other objects that are less perfectly balanced. I don鈥檛 know how to juggle clubs, because the drill-and-kill instructional methods I was taught did not impart a lifelong love of juggling. If you want to develop a really impressive juggling act, then at some point you鈥檙e going to have to go beyond drill and kill. But most people can鈥檛 juggle at all, and they could if they received explicit instruction and practiced.

My son is a competitive swimmer, and when his team practices, they do a good number of repetitive drills because the coaches are trying to get them to swim properly. Lots of kids love swimming for fun in the summer, but you鈥檙e not going to win a race unless you receive a lot of explicit instruction in exactly the right way to dive, to turn, to kick, and to hold your arms. Unstructured discovery is never in a million years going to lead a child to a biomechanically optimal freestyle, much less a legal butterfly.

He also used to be on a much more low-key soccer team. But the team still had practices, and the practices still had lots of explicit drilling. He also plays soccer for fun at recess, which is great. But if your team wants to win games, the players need explicit instruction in how to use their instep to control a pass and how to do a correct throw-in from the sidelines.

Imagine trying to learn how to tie a tie via 鈥減roductive struggle鈥� rather than just. That would be insane!

Now what鈥檚 true is that if you want to, you need to obtain a deeper comprehension of the relevant topology and probably do a fair amount of exploration. But just learning how to do a four-in-hand or a half-Windsor is really easy if someone teaches you and insanely frustrating if you鈥檙e left to flounder and figure it out on your own.

A disservice to everyone

Math professor Anna Stokke has been in the trenches battling bad math instruction techniques, and I strongly and on this.

But the basic point she鈥檚 making is really simple: Deep understanding is not generated through some separate teaching process that replaces drilling; it鈥檚 an outcome that comes several steps after mastering the basics. Whether it鈥檚 a tie knot or algebra, you need to learn how to do it first, then practice it until you鈥檙e fluent, and then you can explore.

One irony of unions and left-aligned institutions derogating practice and drills is that 鈥� like with progressive attacks on sorting students by ability 鈥� this approach in practice does a huge disservice to classroom teachers by saddling them with an impossible job.

Teaching is a complicated, multifaceted profession that is difficult under any circumstances.

But to the extent that we can simplify the actual content part of the job by giving the teacher a class of kids who are starting out in roughly the same place and then trying to impart a defined set of skills to them, the work is at least doable.

This is the reason why sports coaches and birthday party magicians and unemployed cooks are able to teach people how to swim the butterfly or juggle balls or cut an onion, even while middle-school math teachers are struggling to get kids to do division. You need to let the teachers just teach division!

One thing I didn鈥檛 convey as clearly as I wanted to in is that outside math tutors aren鈥檛 just being used by families in 鈥渂ad鈥� schools 鈥� by parents who鈥檝e already moved to the upscale suburbs with the 鈥済ood鈥� schools. Just look at the D.C. suburbs:

There鈥檚 no big secret to what these private classes are doing; it鈥檚 just.

Kumon has not discovered some secret stash of super-teachers capable of feats beyond the comprehension of normal K-12 educators. The program just gives its instructors a feasible job: show kids how to do the problem and make them practice until they get good at it. We can do this in normal schools, too, but we have to let go of this paranoia around 鈥渄rill and kill鈥� and just be normal.
