Let's see if I can sort things here.
- Tools, materials and a frame what the kids have to learn or the group wants to learn, is essential.
- Trust to that group, what ever happens, is more than important.
- Learning comes from doing. That is therefore crucial that both kids and adults in a learning process can try out different ways to come to an understanding.
- Learning cello is doing by actually playing the cello, that is learning by doing, by trust from the teacher, family, friends and with a hand by tools (cello), materials (sheet, a space to be etc) and a frame (teacher, notes).
- Learning chemistry in a lab is that too, as well as riding a horse, be in a team in the forest to learn rescue.. all these are something else than read about it in a book, or listen to a teacher; when you learn as long as you do.
I don't think the world needs less teachers, but I think that the world needs better methods to teach. More pedagogues instead of lectures; for more understanding, more trust and better self-confidence. More dialog, discussions and practical learning for a deeper understanding and a better learning in the long run.
Because learning is doing, and doing is learning. That is what it's all about.
