Do we stop teaching people too soon? there's some interesting stuff there, with clear reference to ringing. But I think this, and many of the comments on the parent thread about peal ringing, misses the point by homing in on 'teaching' alone. There is plenty of scope to improve the way the skills of ringing are taught, but that's not enough on its own.
For people to develop into long term, capable, ambitious ringers who will make a positive contribution to ringing, they need to absorb the ethos of what ringing is about and a sense of being part of something bigger - of the wider ringing community and of the tradition and future of ringing. They also need to absorb a sense of the many different facets of ringing.
They don't get that from LTR, or from how they are taught to handle a bell, or from learning the mechanics of hunting. They absorb it in the way that any culture is acquired, from the people they come into contact with, notably other ringers.
If they are surrounded by ringers of low skill, low ambition and limited horizons then that is the culture they will absorb. And having absorbed it they will become part of it and help spread it to others. Once a band gets to that point it is very difficult for anyone to escape, given the lack of either opportunities or inspiration to do more. They will assume that 'this is what ringing is like' and either go with the flow or give up because it doesn't give the opportunity, challenge and satisfaction that they need.
