Schools Beat Earlier Plagues With Outdoor Classes

And it stays pretty unbearable until late October or so.
Yes, I know the article wasn't insinuating that the entire country, regardless of climactic region, should hold outdoor classes. But enough of the US sits below "unbearable" latitudes enough of the year that I don't think this suggestion has much applicability beyond what is explicitly considered "the north". Besides, I've been to New York City in August and September before; depending on the day, the heat, and especially the humidity, can give the South a run for its money.
It's not very conducive for learning. Take some cognitively demanding task you have to do or struggle with and then try doing it in sweltering heat. At least for me, my patience recedes very quickly and I'm far more concerned with my immediate discomfort than I am dancing through some abstract ideas, making it very difficult to focus.
And they didn't have school on hot days. Source: My school had no air conditioning outside of the nurse's office until I was in high school. If the temperature was above 89, school was cancelled for the day.
For other cooler areas of the country, perhaps winters off, but not summers?
Wind patterns near the ocean can have the same effect in some places.
(I'll admit I only skimmed the article. It may have addressed some or all of these points.)
Yes, it could be done, and should be considered. However, school years used to start at Labor Day, for this reason, and there were a lot of serious metal-bladed fans to make it bearable. Even outside, you would need shade (perhaps canopies?) and fans.
It was also a lower population density than modern urban schools. All that body heat makes a difference.
However, definitely worth considering, and in many non-urban areas I believe it could work.
I imagine fans may be problematic due to the way COVID19 primarily spreads. You might be able to design your way out of it with clever fan and student placement but without that, you might create highways for the virus to spread from one student to the next.
Ultimately the best cheapest defense building wise would be airflow over 12 CFM in a top to bottom way. This is essentially an air curtain strength.
That's rather expensive and takes a lot of big fans or very strong HVAC system with many air outlets.
Being outside only works as long as you can spread people out heavily enough. It's better than unventilated buildings, but the benefit is overshadowed by density or distance.
(See: Florida beach policy and cases after the delay.)
1. Droplets directly exhaled. This is the stuff that you mask for.
2. Particles suspended in air. This is why staying indoors is particularly dangerous; it tends to hang around and build up without being vented.
The virus dies quickly outside of droplets and in direct sunlight: this is why being outside is low risk given masks and distancing. Either it's coughed on you, or it dies within minutes.
An indoors area that circulates its air quickly is almost as good, provided UV is part of the process. Fans are mostly a good idea in this respect and one could imagine an indoors "UV gate" through which air is pushed to disinfect it. I would not be surprised if the idea already exists.
And, yes, schools here also used to start later due to the heat.
I may take some heat for saying this, but I also think that people were generally tougher back then as compared to now. What I mean by that is that people had less comforts and were consequently more accustomed to being uncomfortable. It was normal. In my experience, my body adapts and gets conditioned to the climate over time. After some period of time in a particular climate, your body gets used to it (the new normal).
I agree that it's worth considering. I think that there would be a lot of complaining and discomfort at first, but it would be quickly resolved.
Being a coastal town in California, the weather is pleasant for all but a few weeks to a month of the year. For that time period, the weather is hot and miserable. All the windows open and the fans on won't help much, but it's the same at home. Hardly anyone has AC at home here, so whatever.
When the schools were remodeled, all of the classrooms gained air conditioning. In the older schools with the huge windows and the outdoor corridors, the AC units were mounted above the corridors. The windows on that side were sealed off. The windows on the other side were replaced with fat tinted windows that barely opened compared to the old ones. The remodeled campuses are a lot gloomier than the old ones because they're loud and the air in the classrooms is stale. They're also dimmer because of the tinted windows.
But there was a catch: we had a pop quiz. 20% of the grade was some question about a book we read. The other 80% was to write a short essay: Explain the educational benefits of going outside.
They're cheap to build, keep everyone dry, shaded, and reasonably cool. It's obviously not as good as air conditioning, but I've worked under them when on a camp staff in central Georgia during some extremely hot summers in the '90s (and the 90s/100s F) and it is tolerable for most people.
Brief research tells me the construction cost is generally under $25k which is a blip in most education budgets. As a bonus we have more outdoor community space when we manage to get past this.
Even if these were only around existing school property and different classes used just morning or evening the kids could still get some instruction, the parents could have a brief break, and get food (and God forbid some other help for the kids at risk) for the children who need it. We'd be in a much better place than we are now thinking that young elementary kids can do virtual learning.
This would go a long way with getting us through most/all autumn in much of the US.
This was before widespread laundry machines and dishwashers. Those "stay at home mothers" worked. School was, and still is, in part a babysitting service. If the kids were to stay at home they would have been helping mom, not asking her for reading lessons.
This was also a time of increasing literacy and education overall. Illiteracy was not uncommon. There is a good chance that many parents were simply not as well educated as their school-age children. Homeschooling is all well and good, unless mom cannot read.
I'm sure some parents or school studenta were illiterate, but not the majority.
And families were larger, so they'd have multiple children to teach each other.
They got by better because children were in school. If you don't have to keep an eye on your kids, you can commit 100% to all the housework and get it done that much sooner.
They were productive with or without the children around. The point is that there was no productivity to spare for mother and child to do any teaching/learning.
I'm in New England. The sheer number of students and the percentage of them who have inadequate Winter clothing and food would make the strategy impossible to implement as a one size fits all approach.
A quick search shows that my school district has 10,479 students. The number of students on free or reduced price lunch is a good indicator of access to adequate Winter clothing as well. We have 44% of the students on free or reduced price lunch. To implement a strategy of windows open or outdoor classrooms, we would have to account for 4,610 students' Winter clothing needs for temperatures ranging from 0F-55F.
Some communities have much higher percentages of students on free and reduced price lunch. A quick look at a neighbor city 15 minutes' drive to the north shows 95% on free or reduced price lunch.
Districts less affected by poverty could probably implement an outdoor or windows open strategy. But a mountain of logistics exist in trying to implement in communities like mine. Unfortunately, in our county, communities like mine are the norm.
We know that cats, dogs, and a few other types of animals can be infected with SARS-CoV-2
Utilizing outdoor space is a good idea until late fall in the northern US, and possible due most of the school year in places with moderate climate.
Moreover, some schools have only small 100% paved outdoor areas.
Example: Ánimo Westside Charter Middle School (funded by Gates Foundation) https://goo.gl/maps/Wn2bu5kkh97Ygqt88
Nearby public elementary school adjacent to nature area, with ample unpaved space, somewhat less noisy, bit still problematic. Playa Vista Elementary https://goo.gl/maps/tydUVn1X9ppB7p699
(Not complaining about charter schools, but this is an interesting juxtaposition, unrelated to the main point of this topic.)
Also, for that power/propane bill, you're probably better off with either per-desk transparent positive-pressure medical isolation tents or full-face snorkel masks fitted with 3D printed adapters to ceramic-element anesthesia machine air filters.
In addition, kids play. Some small percentage of those kids are going to get burned by heaters.
Radiative heating outside, in winter only works if you have some kind of shelter to reflect and contain the heat. Even then you have to be mindful of your environment.

EDIT: Can't believe I forgot about solar chimneys and evaporative coolers (aka swamp coolers).
Outdoor classes where you don't have the benefit of good ventilation, shade, and your only area large enough to hold outdoor classes might be a blacktop is going to be a little rougher. Without having the building to act as a wind tunnel constantly moving the hot air out you have no chance when the wind dies down.
There is no good data to back that up. Since we've been keep track, most kids have been staying home, away from other kids. Schools have been closed, playgrounds have been closed, and so on.
There is a good chance it doesn't affect them as much, but it's not entirely clear since they haven't been socializing as much as adults.
The data we do have says that COVID-19 is 3 times deadlier than the flu for kids 5-17, and 190 times deadlier for kids 0-4, but that's because the numbers are small: https://i.insider.com/5ef234caf34d051bc821d0d8?width=700&for...
Also, lots of adults work in schools. 1/3 of teachers in the US are over 50.
And the grand parents and obese parents are vulnerable as all merry hell.
In Iceland, they did extensive testing, and genetic tracing of infections.
Children infecting other children was extremely rare. In almost all cases, it was adults infecting them.
There was only a SINGLE case of a child infecting an adult.
https://www.sciencemuseumgroup.org.uk/blog/hunting-down-covi...
Lockdown effectively places every family into its own bubble. Family members can only get infected by someone interaction with the outside world. If the kids stay home and only the adults interact with the outside world, than we would expect to see basically zero child 2 child infections.

What we don't know is how effective kids are as transmission vectors. If COVID19 spreads rapidly through a school and kids can get thier caretakers sick, thats a real problem. The limited data we have in suggests that not only do young kids not have limited disease, they also don't spread it easily, but all the data I've seen is almost anecdotal.
That's just straight up wrong. According to the CDC, as of June 23, COVID-19 was three times deadlier than the flu for kids 5-17, and 190 times deadlier for kids 0-4:

It's best to say "the fatality rate is near the same order as the flu for school age children"
https://www.thedailybeast.com/israeli-data-show-school-openi...
The article is arguing a point, but it also links to a lot of the other papers I've seen.
Note that "not as transmissible" doesn't mean "not transmissible". It's entirely possible for the disease to be harder to transmit in kids but still be enough to sustain community spread. I think we don't know yet.
That's not a full-throated endorsement of reopening schools, but it should inform a risk/reward based approach to what institutions should close or open and when.
Currently, the virus is out of control. We might be able to bring it back under control. The Israeli experience suggests that, since half their cases were from schools, opening schools doubles R. There's no measure that will be realistically implemented in the next month that would cut R in half.
It could be that this is the least bad of a set of options. Convince me.
Universal masking can cut R substantially, but it requires high levels of compliance [1]

Schools are a particular problem. Getting kids to consistently and correctly wear masks is hard. Getting kids to follow social distancing rules is hard too.
Bringing a bunch of poorly compliant people together to sit in the same room with 25 other people is gonna be a big challenge.
We do know that kids can be transmission vectors and there is nothing to suggest they cant be.
TL;DR - "doesn't kill you" might still maim you for life

“We don’t know yet if the encephalopathy is more severe with Covid-19 than with other viruses, but I can tell you we’ve been seeing quite a lot of it"
That is probably the type of information we should be taking from these media reports. Given that there are over 14 million cases globally, we should be looking for patterns that impact tens of thousands, not edge cases that impact dozens or hundreds. With such a closely-studied and brand new disease, we are bound to find a lot of interesting and worrying cases. There are plenty of rare symptoms from other diseases too, we just don't talk about them much because they are not new and they are rare.
Since there is a lot of proof the current virus is airborne it helps to be in the open air or at least have a good ventilation system.
Schools could beat the spreading of the virus with well ventilated classrooms.
And for that matter: the US could beat the virus with good ventilated rooms. Note that dry air from airconditioners helps airosols to keep floating.
Without fress air: wear a mask!
But I bet students could have better learning outcome, considering that indoor space are often poorly ventilated and have an excess of CO2 https://www.nytimes.com/2019/05/06/health/conference-room-ai...

US Schooling is very inconsistent and varies a huge amount by municipality.
Day dreaming looking out the windows at the hills or sea was a favourite activity of mine!

But yup, many rooms had no windows; just a big cinderblock room, the only window being by the door, opening into the hallway.
You don't tend to get windowless classrooms until decades after the building was built and the school is simply making due with the facilities they have in light of their changing needs. They'll shove a math class in a former art room or something.
Back in the day windowless rooms were somewhat coveted because everyone had lesson plans on transparencies and they'd teach using the overhead projector the way some teachers use a PowerPoint today. Being able to turn down the lights (and not have the sun defeat your efforts) and then have the projector be the main focus helps keep the class on-task and keeps the teacher in better control of rowdy classes because the people who would drift off topic and engage in distracting chit-chat tend to drift off to sleep instead.
I personally wouldn't even accept a short-term contract that involved spending a large proportion of my time away from natural light.
You can't do outdoor classes in Texas in August, but by late September or October it becomes totally feasible.
Hospitalization rates in the US for covid is:
0% for 10 and under
.1% for 10 - 20
In the US, the number of deaths for covid is:
20 (total!) for 0 - 14
125 (total!) for 15 - 24
By comparison, suicide caused 514 deaths for 10-14 year olds, and 6500 deaths for 15-24 year olds in 2017.

By comparison, the CDC estimates that around 600 children died of the flu in 2017/2018.
