Lots of questions here, the first being What can YOU do to support the teachers and correct this probelem??
How many children are in the class? how many adults in the class? Are all the adults equally certified? What process is there for drop off? What are the teachers doing while this is happening? What do you want them to be doing? Have you observed during the actual preschool "day"? is it crazy at story time, is it wild at snack?? Is art time insane???
I will go back and read your previous posts to try to get a better handle on the situation.
In my opinon If the doors to preschool open at 9 am and there are 15 kids hanging up back packs and greeting teachers, and then there are four moms standing in the middle of the room chatting about the new nail technician down at Magic Manicure, and 8 siblings between the ages of 6 mo and 2.5 yrs running all over, and 3 more mom's monopolizing the teachers because lil Janie's fingerpaint paper that came home really wasn't her best work and could the teachers agree to give her more time and more paint next time so that she can better fulfill her artistic needs. and oh My Johnny has been waking up a 4 am and i know it has nothing to do with the fact that i had him up until 10 pm at his big brothers baseball game where he ran around for 2 hrs and drank 24 oz of coca cola, but would you please talk to the other kids and tell them that Johnny doesn't apprecate them looking at him. and I need to pick Maisy up right in the middle of class because i want to take her to mcdonalds for some one on one time, because i've been very busy at the gym and hairsalon lately and haven't really spent much time with her.
The best drop offs are where the parent, hugs the child and leaves, wile the kid gets engaged in an activity and the teachers are free to supervise.
Perhaps you can suggest that playdough or free coloring are out so the kids are busy but sitting. and ask that parent conferences of any length take place outside of school hours.
I'll also throw out that disciplining while the parent is in the room can be very very touchy, If my child is in the room with me, I expect that i will be watching him and disciplining he, I wouldn't leave it up to the teacher.
Also, chances are you have no idea if some of these kids are special needs and the teacher addressing it AT that moment would cause a total freak out. Not that they shouldn't be disciplined but ... I"m just saying there may be more to it than you realize.
If you can identify which children in particular are being the most aggressive you could try addressing it with the director and possibly having those children removed.
like i said i'll go back an research your posts. but to me supporting the teacher always seems like first best choice.
edited-- ok i have gone back and i see there are 18 kids and 2/3 teachers. Also alot of what you are concerned about seems to be taking place outside. Is that were drop off occurs? Is it possible to bring your child later right before circle time starts?
If this is an actual preschool, i think there are solutions, if this is a daycare that you or the organization it'self is referring to as a preschool ( ie More than 3 hrs per day usually 3 days a week) then i would leave.
Last question, In my area true preschools (3 hrs per day 3 days a week) run from sept to the end of may. Is this an issue because you are re enrolling for next year or is this an issue because it is a year round program?
Please let us know what happens at your meeting. I'm sure the teachers aren't happy to go into work each day and have to deal with these sorts of incidents, so i'm sure they want a solution as much as you do. Just curious, do you know how much they are paid? and what each of their certification is??
