The same teacher has been there for 17 years, what can I say, I never see her talking to the kids; I never see her playing with the kids; I never hear her catching the kids being good, but she quickly admonishes them when they do something a little wrong.
Preschool is semi-co-op, you need to help 4 or 5 times, and you need to bring a snack about 3 times. There are lots of toys scattered around, but not teacher playing with them. There are lots of big cars, an indoor jungle jim with mats and a slide, there is a doll house, a train table, a little kitchen and a little work bench.
The kids arrive, have free play for 30 mins. then a couple of books are read to them and they sing a couple of songs (note that they really aren't taught the songs), then an art project, then hand washing for all the tots, then a snack, more free play, then dismissed.
The art project is always nicely organized: sometimes the children get stickers to put on a cut out house, or, put a feather on a bird, or, color a paper crown.
Basically, there is no teaching. No alphabet letters, no positive reinforcement, just a lot of chatter between the teacher and parents.
This is cheap, and a safe environment for kids to play and begin to learn how to do what they are told in a group setting. Not much more.
