I recently had to write an essay about an aspect of 'play' and chose war, weapon and superhero play as my topic. To begin with, I was probably against it, but all the background reading changed my mind...
It's really interesting; so many schools (and parents!) have a zero tolerance attitude to gun play, yet there are no clear, written policies from either schools or LAs to explain where this approach has come from.
There is also no evidence to suggest that playing pretend shooting games will make children any more aggressive or violent, or likely to shoot anyone for real. In actual fact, some research suggests that it can reduce aggressive behaviour, as children learn the differences between real and pretend, and are able to distingish appropriate behaviour in different situations.
Children will see shooting and violence around them; in the news, on tv, in books. Play pretend can help children make sense of what they have seen/heard, where they may not have the necessary skills to verbalise and talk about it like an adult would.
After all, its just another dimension of the fantasy and role-play that is so well recognised as having benefits for children's development. Most schools have 'role play corners' set up, so are children playing pretend outside shouting BANG BANG really much different?
I'm not saying that when I have my own classroom, I'll order in 30 toy guns for the children, but if when some of them inevitably make guns out of lego or their own fingers, I don't intend to barge in and stop thier imaginative play!
