A definition
We use this term to suggest kids physically engaged with technology.
If they are using a computer, it is as a tool to control something, such as a robotic arm. Or they might have built a small vehicle, now being used on an inclined plane. Or a small boat with a sail might be timed as it crosses a tub of water.
In these examples, students are at work planning, building and operating some aspect of technology, whether simple or complex.
