My children attended Montessori schools, and it really is a wonderful system.

I would really like to see an extension of this learning method up through high school --- the closest thing I'm aware of was a school I attended in Mississippi for a couple of years --- classes were divided between academic and social, social classes (homeroom, phys ed, social studies, &c.) were attended at one's age, while academic classes (reading, math, science, geography, history, &c.) were by ability (with a limit on no more than 4 grades ahead up to 8th grade) --- after 8th grade that was removed and students were allowed to take any classes.

Some of the faculty were accredited as faculty at a local college, and where warranted, either professors travelled from there to the school, or students travelled to the college for classes --- it wasn't uncommon for students to graduate high school and simultaneously be awarded a college degree.

Apparently, the system was deemed unfair because it accorded a benefit to the students who were able to take advantage of it, with no commensurate compensation for those who were not, so the Miss. State Supreme Court dismantled it.

I had a good impression of "Montessori" from hearing that Larry/Sergey/Bezos went to one. When I put my kid in it at 3 years old, he hated it. As I looked into it more, it seems to me that it is actually very rigid, with kids being able to play with just a small set of toys that don't really exercise their creativity, and with little opportunity for group play. We switched him to a Reggio Emilia school where the kids are constantly doing group projects and art and he enjoys it a lot more. I recommend parents observe what's actually happening in classrooms and think about what's best for their kid in the early years instead of assuming "Montessori" is the best path.

Like anything, there are lower and higher quality implementations of Montessori programs. What you are saying here does not reflect the Montessori program I went through myself, and I think I can credit the Montessori program with a great deal of my later stage curiosity and drive to outperform.

I would say the same of the public high school that I attended. The attitude of the teachers and the other students was fantastic, and it really helped propel me forward in life, gave me a ton of lessons that I don't think most people were able to take from their own public high schools.

In both cases, my parents (Mom especially) were so incredibly stubborn about finding the best school for their kids. We literally moved the whole family to the town that had the best public school where my parents could afford a single family home. Love you Mom, thank you for caring, and to all other parents I would strongly advise against picking a school based on its philosophy. The quality of teacher matters much more than anything else.

Same here. My three-year old loved maps and we always played with them (making map of her room, etc etc)

We enrolled her at the local Montessori and she rushed to the map section but was told she is forbidden from using it until she takes the lesson on that or whatever is called. That lesson was 2-3 months away, and meanwhile all other kids were able to play with the maps.

This, combined with other rigidities and a crazy schedule totally unsuited for working parents (9-1pm wtf) made it impossible. After struggling a lot for two months, she went back to her old daycare and was very happy there, and is now at her elementary school now

There are different “factions” and accreditation organizations in Montessori. Some are more liberal and others are authoritarian and rigid. Not all Montessori schools are like you describe, but some certainly are.

I attended one for elementary and middleschool. Early on everything we did was in groups. Take the multiplication flash cards and quiz eachother. Mess with the abacus. Look at the geological periods chart, etc. All the stuff seemed pretty fun to me. Yes, we had outdoor recess everyday, alhough we had a good setup with a big playground and some woods on the property. A lot of montessori setups I see now look really spartan like almost a daycare center.

But in hindsight I could tell it depends heavily on the teachers as well as the students you are saddled with because of how much group stuff there is. There was clear divisions between the kids who would reliably do their work and the kids who procrastinated and played around flicking pencils at eachother all day. This was generally possible while the main classroom teacher was busy with some subset of students for a lesson or some other work.

Once we got access to desktop computers we replaced the pencil flicking all day with games. They'd be in the main classroom but we'd just turn the crt monitors to the side to hide it. This was long before IT surveillance tools, we had full internet access too. Gameboys a plenty.

There was a lot of fluid experimentation however. At one point we took all the shelving in the room and turned it in such a way to create sort of cubicles. I think the idea was to get the kids who probably had ADHD to lock in and do their work more vs being tempted to socialize and screw around all day with their friends. Eventually they banned us from turning the CRT monitors as well.

Would a more rigid school structure help other kids? Sure, probably, but I don't think what public school was doing would have helped those kids much. Honestly montessori is a lot like the adult working world now that I am in that and see the parallels. A lot less handholding and you needing to not give into procrastination and ask mentors for individual direction from time to time. Group work and discussion coupled with independent work. Project based education that is more like actual real life work projects vs the dry lecture/memorize/exam patterns. That being said it was more "traditional" and less montessori towards the end as they had to prepare you for a proper highschool setup, so more formally scheduled classes and a lot less free time in the main classroom.

> it is actually very rigid, with kids being able to play with just a small set of toys that don't really exercise their creativity

There exist various implementations of Montessori. AMI was founded by Dr. Montessori [0] and certifies schools so that parents can have some assurance of adherence to a standard. The many materials in a Montessori classroom, including things that look like a dollhouse, don't exist for unstructured play but are learning tools for the guide and student to use in their work. Once the student gets a lesson using a material, then they can choose to practice using the material in their self-directed work periods, which can be in groups.

My kids had a mostly positive mixed experience in Montessori. In addition to evaluating how a child comes to grip with the method, there is also how they work with their guide. My observation is that even skilled practitioners don't always achieve a strong rapport with every student. In those situations the Montessori classroom's weakness is that there is only one guide for all subjects as opposed to a traditional school's subject-specific teachers.

I don't doubt your experience, but mine was the opposite. I went to a couple of different Montessori schools, from kindergarten through 6th grade. The majority of our day was what I would call "structured free play"; even in 6th grade, I think formal "sit down" lessons were only half the day. Teachers would often do impromptu sort of lessons for a single or small group of children, like if they were playing with map toys they'd come over and talk about different countries and the weather and food and whatever.

The rest of the time had loose guidelines on what to do (like you should read X pages of any book in the library) or you were free to do/play with what you wanted once that stuff was done.

We were largely encouraged to do things in a group. I think the only place to even sit alone if you wanted was the book nook, everything else was communal tables.

I really enjoyed it, and was ahead to the point of being bored when I switched to public schools. I tried for like a week in 5th grade and they were covering geographic features I'd already done back in 2nd or 3rd grade (archipelagos and islets and what not).

I have a book "The Montessori Toddler".

We read a lot with our son who is almost 3 now. In the book it is recommended not to introduce fantasy in books until 6 (when apparently children suddenly understand the difference between fantasy and reality). I assume this is an original Montessori teaching.

Anyone who knows childrens books knows they are around 95% fantasy stories containing anthropomorphized animals (and some cars/trains/planes).

As far as i can tell our son knows the difference between what we read in books and the real world, and has done for a while. The things we read in books we discuss while reading. In the real world we discuss real world things. He has never shown behavior that would suggest these are mixed up in his head.

Maybe I misunderstand their point around fantasy/reality. But the seems so obviously wrong to me that I would be cautious about the rest of their teachings. Which does seem to contain some good advice.

I had the exact same experience except my child is still there. No free play, very little time outdoors, very little interaction with classmates, no creativity allowed. Unhappy child who regularly doesn't want to go. We try to give her outdoor play with friends after preschool to make up for it.

We will soon be picking a school for our oldest. (Not in the US.) We're choosing between a Montessori school and a couple others.

I see a lot of sentiment along the line of "quality over philosophy" -- how can we evaluate quality? There is limited data available[1]. What do we ask the school when we visit them?[2]

[1]: Unsure if standardised test scores really matter at a young age, so we're grasping for straws with "fraction of parents with tertiary education" (higher means children have more progressive views?) and "fraction of girls in each class" (higher means calmer classrooms?).

[2]: I don't know how to evaluate schools so my best ideas are to ask about staff retention (is it a tolerable environment?), how they evaluate that they get the desired effects out of efforts (do they do things purposefully?), etc.

Montessori is just an educational framework, I have no idea where you draw broad conclusion that the one or two things you looked at deemed it be "rigid" or little opportunity... Sounds like a random bad apple. There's a correlation between gifted children and montessori because it allows them to develop at their own pace which is often faster than that of traditional classrooms etc, it's not for everyone.

It's hard to do self paced learning when there's no follow up. I got put into a self-paced learning experiment where we polished off the curriculum in three weeks and played chess the rest of the semester. There was nothing else for us to do. Nobody was ready to fill the remaining months. The whole school has to commit in that direction for that to succeed.
WillAdams · 2 months ago
Yeah, as one worked forward, one would arrive in the new class and be handed a stack of work required to catch up to where the class was at (moving forward at the end of a school year was strongly discouraged, but some kids would do it --- if need be, one could take the unfinished assignments home at the end of the year and work on them over the summer, turning them in at the beginning of the year).

My biggest skepticism about Mamdani in NYC is that he wants to get rid of gifted programs. Apparently some thing it's wrong to adjust each child's learning experience to their capacity for learning. Which is... Wild.

If an 8 year old can do algebra, let them cook.

lazyasciiart · 2 months ago
That’s not what he said. He wants to get rid of kids being tracked into gifted kindergartens because a) it’s ludicrous and b) testing four year olds is just a roundabout way of finding the kids with parents who got them a tutor for kindergarten entrance exams, and the replacement metric of getting pre-k teachers to pick them is not much different. He argues that kids don’t need to be shuffled off to special schools until more like 8 years old, when the 2nd grade testing happens.

He also obviously doesn’t believe it’s wrong to adjust learning to capacity. He just has the less popular view that this can be done without tagging kids at four years old and changing their lives. (He probably also understands that there’s plenty a brilliant math kid who belongs in a standard English class, or even in remedial classes to deal with a concurrent learning disability).

I’ve been advocating for this for years so I’m glad to hear you had such a good experience.

At the elementary level, up until about 3rd or 4th grade it always made more sense to me to have lots of smaller “neighborhood” level Montessori schools rather than a few large schools from Kindergarten - 6th.

> while academic classes (reading, math, science, geography, history, &c.) were by ability

My issue with this is that it just is selection bias, telling you nothing about how good the method is at teaching.

Does placing by ability actually helps student learn and score better? Or it's just that those who are good and bad already get divided up, and we know not why some are good and others are worse?

michaelt · 2 months ago
> Does placing by ability actually helps student learn and score better?

Yes, you shunt all the disruptive/obstinate kids into class 2 and they can spend 4 hours of math lessons every week rehashing arguments about how they have a phone so they don't need to know what 7x12 is.

This means the students in class 1 get undisrupted classes, learning more and raising their grades.

Because of the way these things are done, it does have the unfortunate side effect that the kid who struggles with math because he's dyslexic gets put in a class with the kid who doesn't give a shit about math. But they'd be in the same even if the school didn't place by ability, so they're not that much worse off.

aidenn0 · 2 months ago
From my limited observations it must; at least in cumulative subjects like math.

Too many kids are just completely lost because they were moved up to the next math class despite not understanding the previous math class.

I came to comment (without reading it) that the study results are probably not universal. The programs are self selecting because kids not suited for it won't stay. This is not a critique of the program or the kids who dont fit it. Just an observation that its so "extreme" that only kids who benefit will stay.

Absolutely, how many ghetto kids are in the school? It weeds them out through $ and expulsions.

Thinking the Montessori system is relevant to the public system shows your schooling failed.

Montessori has the ability to chose pedagogy so certainly has facets that are the quite good and should be applied publicly except for liberal arts graduate ideals.

This study is very young children, limited pregnancies and gang bangers, and also not random. It's randomised on kids who enter the lottery.

Discipline is the only thing that matters in schools, $, class sizes, teacher education levels above average, amazing resources all don't matter except how it apply to discipline. We have 100+ years of data. Air-conditioning to control behavior is an example of what helps. Liberal arts graduates destroy anything else that could work so don't interact with them, stay outside their broken world.

I thought it was parenting? This study claims that "parental involvement is a more significant factor in a child’s academic performance than the qualities of the school itself." [0]

the montessori method implements discipline. that's one of its features. weeding out ghetto kids is not. that's a problem coming from lack of support from the community/government to pay for a montessori school for those kids. and expulsions should not happen. again, not a feature of montessori education.

I send my child to a private Montessori school. With that said, there's no denying that sending your child to a private Montessori school is similar to parents who buy books in learning to parent are typically better parents not because they read the books but because they care enough to buy the books. If you care enough to send your child to a Montessori school, the parent is invested in the child's success and I think that's way more important.

I spent months doing research for a blog post about One Laptop Per Child last year, and came to a related, but more broad conclusion: it's extremely easy to reach misleading conclusions when studying novel educational methods. No strong conclusion comes without qualifiers related to culture and economics. Moreover, a shocking amount of harm has been done by people trying to apply an educational method outside of the socioeconomic context where its efficacy was proven.

There's a dilemma here, because in order to find ways to improve education, we have to try stuff, right? But how do we remedy the situation when those experiments fail? That's less related to the Montessori thing, but it's interesting to think about.

I did high school at a prestigious technical school at my hometown, hard to get in, very competitive. The education itself wasn't that much better than my previous school but they had the name recognition and as getting in was very hard, likely the best students around town.

Almost 100% pass rate to college, mostly the best colleges. Did the education provided there affect this? Likely, but it was much more the self selection of having the best students that were doing a SAT like test to get in.

zorked · 2 months ago
In my hometown there is something like that. There are two schools, one of them had a year with particularly good approval rates. Competitive parents started preferring that school, finding ways to send their kids there. That school has been sustaining better approval rates since then.

Which should make no sense because the teachers themselves work odd years in one school, even years in the other school.

Theres also a lot of college prep going on with private schools. We had far higher college adviser to student ratios than any public school. They started working with you earlier than any public school. No grade inflation and college admissions knew that and knew the reputation of the highschool. Academically the schedule, courseload, workload, things like freedom to pick different electives, were all designed to mirror college.

This is a similar but separate effect. Rich, uncaring parents can raise unachieving idiots.

It’s easier to be caring with resources. But plenty of public school difference-in-outcome studies have found a signal from parental participation that I believe remained after adjusting for income.

My neighbors had just as many if not more opportunities to do so but did not care enough to do so for their children.

Yes, it’s caring. Education as a top priority for poor families is the number one way a parent can give their kid a better life than they had. Most do not even try.

I went to a Montessori school in the Netherlands and feel like it failed me. Just one data point and maybe it was just a bad school.

I have autism and nobody noticed or did anything about it until it was time to start preparing for high school in seventh grade. I had read all the books in the school library but was not able to spell and write. It was just way to easy for me to escape work I did not want to do.

We moved after I started high school and my sisters had to change school because of it. One of the first things they noticed at their new school is how incredibly lazy they where.

I am very happy working as a mailman but I do wonder what I would be doing now if I had learned how to study and learn at a younger age.

I want to offer a different data point. I took my daughter to a Montessori-adjacent school for 3 years. It's not Montessori exactly and they didn't advertise as such but they had a different European name attached to it that is downstream from Montessori. They had multi-age education, stressed in children directed learning and individual growth, they didn't have exams, etc.

I changed my daughter this year and overall I'm disappointed in that school. There were many issues but the most important ones to me where:

- No exams, only individual growth meant there's no guarantee the kid is learning at a good pace. When I worked with her at home I could easily identify many gaps and deficiencies. She's now struggling a bit in her new school because of this but I think it will resolve soon.

- Because they didn't like comparing kids to standards or among each other the feedback I received was useless. It was always "she's doing excellent, we see strong growth" but it wasn't true.

- The school rejected most parent feedback and issues raised with something "maybe this style of education is not for you". For example, I know of a few other kids that had to leave because the school didn't take action against bullying because they didn't believe in punishments, etc.

I have to say there were good things too, in particular my daughter really enjoyed it there and formed strong bonds with other kids. I think in general it was ok for elementary education but I strongly think it's not after that and I now have a perhaps unjust bias against Montessori and derivatives.

em-bee · 2 months ago
No exams, only individual growth meant there's no guarantee the kid is learning at a good pace.

that's not true. it is possible to notice if a kid is learning at a good pace without exams. that is part of what the montessori method is about.

it sounds like this school just picked the things they liked but did not understand the point. the core of the montessori method is intensive observation, to understand what the children need and how they can thrive. it looks like this didn't happen in your daugthers school.

I wonder sometimes if that kind of school is only good for the high-strung go-getter child prodigy types because they are so hands off. But the very lack of metrics and standardization that purports to help with that kind of mission unfortunately certainly makes the shopping a lot harder for prospective parents. Similar with other private schools later on. Is it a good academically strong place where kids get pushed and excel later? Or is it a party den where rich kids joke around and snort coke all day? Hard to tell. It also depends on the student and parent body itself. Good luck :-)

Another thing that kind of tempers my opinion of this kind of school is anecdotal, some friends were lamenting that in their otherwise excellent public elementary school in an affluent district, some parents are pulling their kids out of _first grade_ and moving to private school because "there is not enough homework." What a sad image.

I attended Montessori in the 80s up to high school level and was part of a "gifted" group who went on to a public school a couple of years younger than typical. I was completely unprepared for student bullying in HS and the generally harsh attitudes of teachers. Also my learning style had to completely change, and I did not adapt well.

My Montessori persona was to be competitive about "finishing my weeks work first" usually on Monday or Tuesday, so I could enjoy working with other students on their work lists, and getting a crack at the highschool algebra book when the teacher would let our group at it. I had some strengths in English, math and computing, but weaknesses in foreign language and science where there were fewer opportunities for social learning. Obviously there were no opportunities for that in HS.

In addition to terrible grades, the transition to public school completely destroyed my social confidence and I had to stop playing sports due to my small stature. My dad noted this year (in my 40s now) later that I was unrecognisable after just a few months but he lost the argument to pull me out. It wasn't until my late 20s that I started to find my original confidence.

>. authentic” their Montessori approach was.

Indeed there's all kinds of Montessori.

I can vouch for my daughter's .

If anybody wants to give it a go, my benchmarks are:

1) find reviews of parents, especially no abuse, shouting, kids in the last year should LOVE the place.

2) observe even for few minutes a class in their focus time -- you will feel almost shocked if you haven't seen this before -- like you entered Santa's workshop -- children should be deeply engaged in their activities. If you haven't seen it before you might suspect abuse (that's why point 1 is so important), no way kids love to wipe the floors, lay tables, prepare food and so on, but they actually do.

And all that done in almost complete silence.

Proper Montessori with good, empathetic, dedicated educators is amazing!

notahacker · 2 months ago
Yeah. Certainly if the US regular pre-school system looks anything like the UK one, the difference between non-Montessori and Montessori pre-schools in the sorts of play actually encouraged probably isn't that big. The authors attempt to control for notable differences in the demographics of the treatment group, but they're there (and in this case, the higher incomes of the parents in the treatment group probably not just a wealth effect, but a correlate of other systematic differences with the parents who didn't...)
emckay · 2 months ago
Low participation rate shouldn't matter too much for an RCT right? Just makes the sample smaller so finding statistically significant results is harder.

Different levels of Montessori authenticity make the results even more impressive. They do have some inclusion criteria, like 2/3 of the teachers must be AMI/AMS certified but even so I'd expect a lot of these public school montessori programs to be less "true montessori" than what you'd get at a fully certified AMI/AMS school.

cool_dude85 · 2 months ago
I think the risk is that there is some systematic difference between those who chose to participate and the overall population of public Montessori kids. For instance, maybe those with high incomes disproportionately chose to participate, and Montessori strengthens learning for this group, but if we could measure the whole population the result is more mixed. It can't be a fully RCT if there's some kind of opt-in provision (which is not to say that an opt-in provision is bad, or a study that is not fully RCT is irrelevant).

Having been through Montessori, I think it's fantastic for kids that are naturally self-driven. I had a great time when it came to learning science and English (the two subjects I cared the most about).

Howrver, I was also pretty far behind in math for reasons unrelated to ability (standardized testing and secondary educational success indicate that I'm actually pretty good at math). I also left with very underdeveloped time management and study skills.

Could these downsides have been mitigated? Definitely, and my parents largely made sure they were. But in talking to my peers at the time, my parents after the fact, and parents of to hers that went to Montessori schools, I think the general idea holds.

Point being that self driven education is fantastic for a lot of reasons. But it will also let a lot of kids stay far behind their ability if not carefully monitored.

I think there might be a pattern across education with a strong ideology (Montessori, Waldorf, Classical education, etc) that they aren't very good at recognizing when the ideology is failing a kid. The relatively weak and mushy educational philosophy of a normal public school is also a somewhat reasonable way to run a school that has to take kids wherever they are at and wherever they came from.

I would amend this somewhat to say that most ideologies have aspects that are much less effective in practice than they are in theory. I think this matches your sentiment, but addresses the likely rebuttal of "But X method has this specific element designed to address the shortcoming."

I'm actually a huge fan of Montessori schools, including the one I went to. It was a great experience.

But in my experience and the experience of a lot of others I've talked to, Montessori schools aren't perfect. The method does really well fostering natural curiosity and harnessing it for learning. Essentially, it develops internal motivation super successfully.

But, as I've seen and heard from plenty of parents and at least one teacher, the method struggles with students that can't find that internal motivation. The sort of freedom a Montessori classroom gives you is not ideal for everyone. I think it's okay to admit that.

Sounds like a no true Scotsman: "If it didn't work, it wasn't good Montessori."

Intervening when they are merely far behind their ability!? Sounds like imposing adult anxieties onto the natural development path of a child!

Sure, there's an element of that. But I think it's fair to say that life involves doing things you don't want to do sometimes and Montessori struggles with that.

Any alternative school system is lower-cost than public schools if they don't have to support the needs of students with severe disabilities.

That's taken care of in the study design. The population was all kids who applied to the lottery. And the treatment group wasn't those who actually attended the Montessori school, but those who were offered a place due to the lottery.

So I don't see how special needs would bias the results. If the lottery excludes those with special needs (either by design or due to self-selection) then there's no bias between control group and treatment group. If the lottery doesn't exclude but the enrollment decision is biased by special needs, then it doesn't matter because they use ITT and not enrolment.

Schools are not designed to calculate the actual cost on a per student basis.

Big ticket items like a dedicated SPED department, or a professional working 1:1 with a student can be accounted for. But if a special needs child participates in a standard class (which they do) and the standard teacher needs to do more than average work to accommodate them; that cost is not earmarked for that specific student. Once the bean counters see it, it is just "teacher salary", which gets averaged out across all the students.

Yeah, the intention to treat design is a particularly nice touch, not so common outside of biostatistics. They also compare the full cost of Montessori vs. plain ol', not the cost to the state, which could otherwise have given the Montessori schools (which are in wealthier neighborhoods on average) an unfair advantage if they have a lot of parents chipping in with donations and help. I've skimmed through the methods section and it does seem like they've gone to great lengths to allow for a fair comparison.

That doesn't necessarily mean the result will extrapolate, though. It seems plausible that teachers in Montessori schools are more motivated and knowledgeable than the average teacher and have made a conscious decision to teach in such a school. If every public school were to become a Montessori school, you would still get the cost savings (student-to-teacher ratios are higher in Montessori!) but you might lose that above-average enthusiasm and expertise and so the learning gains might not carry over. It's just really hard to know whether something might generalize in the educational sciences.

Therefore no one should study alternatives to the public schools...?

We accept that different colleges (and other post-secondary training) at different cost points serve different populations.

We somehow do not accept the same idea for secondary or primary education. Why not improve educational outcomes for some of the population?

Given all the money spent on trying different educational models to achieve better outcomes, it's really gratifying to see a result suggesting that improvement is actually possible. I have a lot of teachers in my family and they tend to take the perspective that education is an engineering problem rather than a research problem. That is, any apparent progress is due to extra funding or filtering students or the like.

> "Those costs do not include anticipated savings from improved teacher morale and retention, a dynamic demonstrated in other data."

That seems like some kind of supportive evidence as well. Teachers should logically be happier when working inside a system optimized for teaching efficacy!

Personally: we put our child in a Montessori preschool because we liked its emphasis on self-directed learning (I kind of think all learning has to be self-directed on some level. Even a lecture requires you to listen to and think about the lecture, instead of something else). We later moved him to a Reggio Emilia program for non-pedagogical reasons (there were problems with the building that the Montessori school was in). They're definitely different—in Montessori, he mostly played on his own, and in Reggio we now see him in pairs and groups all the time. I have no idea which is better, but his teachers at the Reggio school seem to like it.
