In some ways, adult education is no different from teaching a kindergarten class—especially when hands-on activities are involved. In a kindergarten class, you can expect a few kids to begin eating the paste as soon as it is opened up for an art project. In an adult education course about digital multimeters, you can expect attendees to start measuring the ohm (resistance) values of everything within reach once you hand out the meters.
Today, I am sharing a photograph of two of my
students connecting the graphite in two carpenter's pencils and capturing an ohm
measurement. While this might stray a bit from my class presentation, learning
is taking place. I like it.
