Philosophy and Kids

Today as I was driving home from ALDI with my daughter, I heard a snippet of 'The Conversation Hour', on ABC radio. Richard Fidler was interviewing a Principal of a primary school, who had introduced a program which involved teaching philosophy to primary school children. If you missed it, you'll be able to download the interview if you follow the link to the website.

If this program is a sign of things to come, then I suspect that it's an added reason why we should be learning to take part in philosophical conversations as Christians. In this comment, Alison Blake (who happened to be listening to the same interview), has already raised some issues that come with teaching kids philosophy.

Are there any experiences you've had of kids learning philosophy in the school classroom? What were the pluses and minuses?
