Without wishing to derail the thread away from Chester and into school children debate, I personally feel schools and zoos are handled rather badly.
I appreciate not all children want to learn about conservation, endangered animals, climate change etc, but I feel when schools book days at a zoo, it should be in a structured format. Every zoo should have a program which involves an amount of classroom time with a member of education staff, to talk to them about animals. There should be some form of enrichment creation and give the pupils satisfaction of seeing the animals being enriched from what they have done. Maybe have a private feeding session with Meerkats or Lemurs to help the children benefit from an amazing day out and go away not just learning about the animals and how they can do more for the environment, but give them an experience so they go away wanting to learn more.
I think the days of numbers of parents and teachers going to a zoo with hoards of pupils, often letting them run off to their own devices and do as they please, should not be allowed. There is meant to be supervision, but it seldom happens. This is not against the Schools or the Zoos, but every Zoo should have a managed education and school program and that the only way a large school group can visit, is by booking this procedure.
In my opinion, that is what a Zoo can do to make it a better experience all round. Recently I've been at two zoos where there was kids unsupervised, One place there was 3 teenage kids smoking around the back of an exhibit. I politely told them that smoking is not allowed at the zoo, and would they be kind enough to not smoke. They pretty much told me to do one, but in more unfavouring terms. I reported it to the next member of staff I saw, who said thanks, but then also said unless they see them doing it there is nothing they can do.
The other visit there was children with an adult present putting hands over a fence trying to touch an Asain Small-Clawed Otter. I immediately said something to the teacher, who to be frank looked as if they were more interested in what they were reading on their phone, than their children putting themselves in danger. This time, I didn't say anything to the zoo staff, as I was just shell-shocked that the supervising adult couldn't give a damn.
However the flip side of the coin, I was at a zoo in Hertfordshire and there was a school group, mainly of what I would class as pre school age. The teacher had them sing little songs back when she said something. There was a lot of organisation, well behaved and respectful children, all walking hand and hand and waiting patiently to see the animals, not taking up all the exhibit. If one of them shouted or done something wrong. The teacher stopped the whole group, got their attention and made them all repeat things after her, and then when they were behaved carried on with their visit. I was really impressed by the behaviour of this group and I observed them 2/3 times on that day. I even sent an email to the school in question (all pupils and teachers had the name of the zoo on jumpers), saying how impressed I was with the teacher and how the children behaved at a zoo, and that they were a credit to their school, and the teacher was doing an excellent job. I was quite pleased to have the email acknowledged as well. I also sent an email to the Zoo, saying that, the school group that visited that day was one of the best behaved I had ever seen, and the zoo should reach out to them, as if all schools were like this (especially this age group), then it would make it pleasant to visit when a zoo is busy full of school kids.
I must say, I tend to avoid zoos in the school holidays and also sometimes I've got to a car park and seen like ten coaches and my heart sinks. But I do think that if zoos created an education program which works with the national curriculum, then it would be so beneficial all round. I appreciate a lot of zoos do offer visits like this for schools, but I personally feel, zoos and schools should be working in a direction that this is the only way to visit and not give the option of a mass parent / teacher and pupil group, where supervision is sometimes suspect and behaviour is often very poor, as this does nobody any favours.
