Wondered how long it would be till someone mentioned Forest Schools. I helped out for the day on a week long session, and it was just like the excellent video. It was a private firm with rich folks kids, but they really enjoyed it. There was some daft activities though where the kids got frustrated as did I, and this mainly involved doing risky things in an over safe way. I would teach them how to manage the risk as did the lady in the video, or forgot about it (this was using a Potato peeler instead of a knife on hardwood?) until they can manage it.
I think teachers are still learning what's best for sessions and age groups, and as long as it progresses and there's plenty of play involved too at the younger ages, it should all be a good thing.
It's right outside a lot of teachers comfort zones. I started with our youngest Scout section (Beavers) and used potato peelers to teach safe stance and technique to whittle a piece of wood to a point to toast a marshmallow on.
Once that was done they worked up through folders to Moras.
Teach and reinforce the basics is the key.
