Why I shouldn’t jump off stairs and other lessons learned through touch.
My bedroom is in the basement of my house. The doorway over the bottom of the
stairs is a normal height. I have a habit of jumping the last few stairs on any staircase, especially when I’m in
a hurry (which is always because I’m always running late). The problem is that a doorway that is a
normal height at the bottom of the stairs is lower than head height when you
jump off the third step. Which
means that I have hit my head on the top of the frame. More than once.
Finally I got into the habit of reaching up and touching the
door frame as I pass through. Why? Because that touch
lets me know how far away my head is from another bump. I don’t know in inches how much space
there is between my head and the frame, but if my hand is touching it I know
intuitively how far away I am.
That’s the power of hands-on learning. It links the world around us directly
with our minds, without having to go through the translation of words or even
pictures. We touch something and
immediately our mind forms an idea of what it is and how we relate to it. We can later put words to it – soft,
poky, scaly, bumpy, whatever – but at that moment, immediately, we know
something about it, without words, without explanation.
Hands-on activities open a new door to the world. We no longer just hear about things, we
really experience them. I learned
in elementary school that a prism can split white light into a rainbow, but I
was still fascinated when a few years ago I actually played with a light and a
prism for the first time. I had
seen pictures. I had seen demonstrations. I had seen a rainbow in the sky. But until I actually held the prism and
moved it myself and saw the light move and change, I didn’t realize just how
cool that one simple principle was.
One of the core principles of IdEx workshops is that the
participants must manipulate physical variables. They must have something to touch, to move, to pick up and
examine. Regardless of the subject
matter – science, math, even social studies and history – hands-on learning is
an essential component of exploration and learning.
