"They're gonna learn things out of it that they won't get playing with 'Dora The Explorer' toys."
Oh, don't get me started.... you got me started: The idea that kids should learn things for themselves first-hand by experience instead of just believing what they see others do is very important.
We see more and more of this going away. When I was in highschool, we actually dissected animals in biology class. Today, many schools have replaced this with computer simulations. The computer simulation may adequately teach anatomy, true. But it doesn't give the hands-on experience of discovering something is a real experience, of trying doing something for yourself. Learning that experience and a child cultivates that thirst for first-hand knowledge in adults too. You just learn so much more when you get out and do the exploring yourself rather than watching Dora do it for you.
"They're young; they heal fast."
Seven years running a parochial elementary school taught me a lot of things; one being that children are made of amazing stuff. They literally bounce back. I've seen a kid running and playing and said, "Didn't you break your arm the other day?"
"That was three weeks ago, Mr. Gollnick. It's all healed now! See."
Amazing... the paperwork isn't done yet and the kid is already healed.
Obviously, you want to supervise children a bit and protect them from serious injuries, but it is not necessary to protect children from every possible ouch. In fact, ouch is sometimes good. In live in general, there will be ouch; you'll have that. It's important for children to learn that ouch is not a big deal but a fact of life and you put a bandaide or some ice on it and you get on with life.
"It's a sense of 'knowability,' that something is knowable.... that you can know them."
This sense of "knowability" is so important. It's important for children to learn -- so that they will know as adults -- that there is no magic inside the TV set... or the computer or the video game console or the car or the dishwasher or an airplane or anything. If you take the back off of the TV set, there's parts inside there, not magic. We may not understand all of the parts... today. But they are parts and they can be understood and, if you want to and are willing to put the effort into it, YOU can understand them. It's important that children be taught -- so that adults will know -- that there is nothing in this world that you can't, if you want to, figure out and know.
I remember several years ago sitting down on an airplane next to a woman and her five or six year old daughter. The daugher turned to her mother and asked, "Mommy, how do airplanes fly?"
The woman answered, "Magic."
I just had to interject myself: "No! They don't fly by magic. The fly by physics. It's really very simple. The air on top of the wing has to move faster to keep up with the air on the bottom of the wing since the shape of the wing makes the path of the air on top longer. When air moves faster, the pressure is lower. The pressure on the top of the wing is lower and the plane is literally sucked up into air.* It's not magic at all."
Imagine if someone had told Wilbur and Orville Wright that everthing around them was just "magic" and couldn't be understood. They were brought up with this idea of "knowability" and so they set out to understand airflow and flight because they believed they could.
* Technically, this explaination is simplistic and imperfect, true. It's close enough, though, and it imparts that sense of "knowability" that this speaker talks about, that things don't just happen because of magic but because of simple forces and understandable mechanism.
