A colleague of mine has 2 sons, the eldest of which didn't start playing rugby until he was about 15. He injured his knee ending his hopes of a military career. The youngest started playing at aged 8 or 9. He learnt both how to tackle and how to be tackled and remains uninjured. she accepts what the her sons rugby coaches say and that is kids taught contact at an early age are less likely to be hurt.
Thus I think that if rugby is going to remain a contact sport, the full game should be taught to youngsters. That said, I'm not sure, as others have said, that general PE teachers and students have the skills to properly teach full contact rugby, nor the desire to learn. So maybe ruby if it is to be taught as part of the PE curriculum should be non contact in that context, saving 'full contact rugby' for those interested in learning with qualified sport specific coaches.
