skills of hand, mind and eye

I have been on a push of late to assure intellectual content in providing lessons in the wood shop. This is based in part on the medical school prescription, see one, do one, teach one.

When you have the responsibility to teach someone else how to do something, you are required to do something more than go through empty exercises. Those exercises are observed, brought to mind, and absorbed at a deeper level. Questions about that? Do something real and then accept the responsibility to teach someone else what you've learned to do and you'll see what I mean.

My students love nothing better than "free day" in which they get to do anything they want, but they also like when I have concrete examples of things they can make and have the necessary materials on hand. The important thing for me as their teacher is that they gain both knowledge and skill, which of course go hand in hand. If I've built those lessons into the day, I've met my goals, and can feel OK as some students do whatever they want, while others work from the designs and materials I offer.

We have been working on the idea of square. Not the shape square, but the geometric relationship of planes (not airplanes) (and not the tools called "planes") that meet at 90 degrees. This requires an understanding of the use of the tool by the same name, the "square." It allows us to check our work, to assure that parts will indeed fit together as planned. We do this with the hand plane and the saw, and use the square to mark intended cuts and to assess the results of our work.

The plane is a particularly pleasing tool. The shavings are a delight.  A sharp plane leaves a surface smoother than sanding. It can be pirated just for he pleasure of its shavings. To form a straight, square edge, it requires attention to grip, posture and position. And the square is the perfect tool to check results. The students can check for themselves and the process invites them to do so.

With the elementary school students this week I offered lessons in engineering. An object that's not cut square will not stand straight up in opposition to gravitational force. An object standing straight up will not resist motion, and will not have strength unless other means are used to secure its attachment. I invited the students to offer suggestions as to how a stick could mounted to a flat plane, with sufficient strength to resist the forces involved in gravity and motion. They suggested using small building blocks to surround the pole that give more strength when glued in place. Others suggested strings and sticks to "triangulate" the attachment. As simple as their constructions were, they were pleased with them, with what they had learned about very basic engineering.

Make, fix and create... Provide for others to learn lifewise.
