Totally out of topic, but what is the habitual class size in elementary school? Mine was somewhere between 30 and 40 kids, and teachers were not afraid to use punishment to get kids to behave. Some were better chalk-throwers than us the kids, and used their skills to keep the class focused. Still, it was often complete mayhem. All of this was before the smartphones, kids these days seem from a different species altogether. I have read somewhere that smaller classes are better.
