I wouldn't be at all surprised if they were sort of similar to my high school, as for the most part it was the basic model of regimented desks, rote learning, streamed classrooms and strict delineation of time into subjects with little crossover.
As far as I can tell, this model was initially developed for training the middle ranks of the aristocracy in how to be officers in the army, and it only ever really works if you are allowed to beat or drug the children as otherwise it is almost impossible to get them to pay attention while sitting still in rows for an entire day. Which is probably why our classrooms got smashed up by bored pupils fairly regularly.
On the other hand, I have a mate who went to a Steiner school, which he describes as 'the first school he didn't burn down' and there it is an entirely different model that is centered around development rather than training. If I had any kids I would be looking for a school for them that was more in line with that kind of environment. http://en.wikipedia.org/wiki/Waldorf_education
