Following a suggestion from a colleague, I’ve made a couple of visual guides for Google Earth. They are in Word format, and therefore easily editable. I have designed them to be printed off, and then laminated back to back, to form a Google Earth mousemat.
There is a simple help sheet for beginners or primary children.
A more advanced guide covers the creation and editing of placemarks, as well as some of the simple tools and settings that students may not be familiar with.
