Sorry, but smaller class size actually does improve the quality of instruction, provided that the teacher is competent to begin with. The reason for this is that the kids all need personal instruction at some point or another (the amount also depends on the subject), and if you have a class of 40, all of the teacher's time will be taken up by solving those problems and no teaching gets done. Larger class size also contributes to more mayhem by the students, kids being kids after all. A class size of 20 to 24 is manageable by one teacher, provides s/he has the required authority to enforce discipline, but if the number of students goes up from that, efficiency starts to deterioriate. My mother's been a teacher for well over 25 years, her sister even longer than that, and they're good teachers too, and they'd shoot your argument down in half a heartbeat. It's not the unions where the request for smaller class size originates, it's at the field level.The Duchess of Zeon wrote:We could pay teachers more money if we had fewer teachers. One problem these days is there's a fallacious theory being spread about that smaller class sizes improve the quality of instruction. It's unproven and it's being pushed by the teachers' unions solely so they can get more bloated membership rolls to improve their lobbying power on Capitol Hill and in the various state capitols.
Personally I've been in classes ranging in size from 8 to 40+, and the quality of instruction and learning was uniformly better in the smaller classes. It takes a seriously good teacher to manage a class of 40 (have had those), whereas having an incompetent teacher is just as good as having no teacher at all (I had to resit one physics course in high school twice because of that).
Your whole model assumes as a premise that the students will just sit quietly and raptly absorb what the teacher is trying to impart to them, instead of behaving like kids typically do. It's so utterly divorced from reality that it isn't even funny.
One way to reduce the number of teachers (but not significantly) is to increase class size to and slap two or three teachers into it. In Finland expanding class sizes in some schools have become a problem, and there is currently one class of 65 students in one elementary/middle school. They have three or four teachers doing the teaching, with the class divided in two and one or two teachers going around helping the kids who have trouble with the stuff while the other two can concentrate on actual teaching. It's been a successful experiment that they were forced to do out of necessity.
I don't know how the American system works, but here teachers are required to do an intern period of a few months under supervision from senior teachers before they are qualified, to ensure that they have some idea of how to teach. Being competent at something is no guarantee whatsoever that you can competently teach it. That incompetent HS physics teacher I had had a doctorate in physics, and could solve almost any possible math or physics problem you cared to put to him (as the vice principal, a very competent math and physics teacher, did when she had trouble with some arcane issue), but he could never explain it in a comprehensible manner (the vice principal said that half the time she was completely clueless about the finer points of his explanations). Being a good teacher is a skill almost entirely separate from the thing you're teaching (though you obviously have to know that too). I've got nearly flawless English skills (written English anyway, spoken is not perfect), but I suspect I'd suck at trying to teach it. That's because I simply cannot understand what the difficulty is. I can, some of it, but it always leaves me baffled when someone doesn't get things, even after repeated explanations and demonstrated examples.The Duchess of Zeon wrote:Another thing to point out is that teachers are over-certified. It's inconceivable that someone with the prereqs for a four year degree, followed by the course concentration, having passed with - say - a B average - couldn't teach that at up to the high school level. Why do you need any special teacher certification, other than, say, an extra quarter to tack onto your degree should you decide you might want a job like that? Teaching degrees would seem to be specialty items for producing individuals skilled in instructing elementary-aged children or younger, and not necessary for Middle School or High School.
Part time teachers with questionable skill level (or practically no skills at all) at teaching makes for disastrous results. Particularly since they would have a high turnover rate, which would utterly disrupt a class by forcing tghem to learn a new routine every few months or even weeks. We've plenty of experience of that here with substitutes who are underqualified or not really qualified at all to teach something doing the teaching. It doesn't work.The Duchess of Zeon wrote:This would, of course, instantly eliminate the squeeze on available teachers, and greatly reduce the costs associated with being a teacher - no lengthy specialist teaching degree, you could staff a school entirely with part-time teachers who teach single courses, even (in theory anyway) - and without the need to pay off college tuition for a teaching degree you'd be able to live comfortably on a smaller salary.
Unworkable with the amounts of knowledge the students need to learn these days. It used to work even fifty years ago when there were less subjects taught and less complex things taught in many of them. But no longer. Besides, the students who take the time to instruct others also have to learn new stuff themselves, so performance usually suffers drastically if they do, unless they are already past the point of what is being taught.The Duchess of Zeon wrote: Combined with the potential increase if we had realistic class sizes, that would be more than enough. One thing that would greatly improve instruction within classes would be more utilization of the students to teach each other. This needs to start early on. Also, we might consider going back to the old system of teaching multiple grades in a single classroom (if concentrating on the same subject). That would allow the older and more advanced students to aide the younger.
In 9th grade I was practically an assistant teacher in English class for my group. That was because there was practically nothing for me to learn there anymore, the result of having started reading books in English two years earlier, so I'd just have been wasting my time otherwise. I helped the slower learners (a couple of them couldn't string even the most basic sentences together, didn't know elementary grammar, despite six years of study, because they didn't care or weren't interested), sometimes using the whole lesson explaining things in more detail to them. Otherwise at least half of the teacher's time would have been taken up by trying to teach them 4th or 5th grade stuff and nobody would have learned anything. If I'd not already mastered what was being taught, I'd not have done that, I'd have just tried to learn on my own while the rest of the class lagged behind.
Another example is one guy in my best friend's class in high school who had an extreme interest in mathematics, he just sat in the class and would occasionally ask questions related more less distantly to things being taught, sometimes so difficult things the teacher was hard put to find an answer if he knew it at all. He'd discuss stuff with the teacher that went a couple of lightyears over the heads of the others. He'd have been able to help the others. But your average student? No, they just can't, because they have enough on their plate as it is.
It's true that bureaucratic clusterfucks are what most tax the efficiency of the system, we have those here, and a large part of it is that the people making the decisions are ivory tower theoreticians with zero field experience. That's what fucked up the education system here along with spending cuts, though our school system still does relatively well. Another problem is that the teachers are not given authority to use necessary measures, though that is being slowly changed, fortunately.
I remember my class in school in 3rd to 6th grade, in some classes where the teacher wasn't a forceful figure and sometimes couldn't get the class quiet, I and a couple of others could by yelling at them to shut up (because we wanted to learn). It more or less worked, because I was known to have a short fuse and no compunctions about using my fists on people who got on my nerves after being told not to. The teachers could at best give them detention, though it wasn't common, but crossing some other kid might have relatively immediate, tangible, painful consequences.
Need for education system overhaul seems to be a universal necessity, but the opinions on how to go about it vary widely.
