When I was a kid first learning about electronics by taking them apart and other general tinkering, my dad usually took a hands-off approach but did look over what I was working on. He stepped in a few times; ie when working on power supplies and making sure the capacitors had discharged or when I was helping change oil that it had cooled down. Using practical examples of learning like these had worked really well for me but was disappointed there was almost no direct interaction with tools until 7th grade in my district. Was also rather surprised that a number of my peers never received even semi-formal training on how to drill or hot glue things together.
