They say a picture is worth a thousand words. This is particularly true when trying to explain something on your computer. Instead of trying to describe it, send a picture!
Jing is a free downloadable screen capture program that lets you create an image or record a video of your computer screen. With Jing you can capture an image from your computer desktop, then save it or copy and paste it directly into a word document. Jing also lets you record up to a 5-minute video of your computer desktop. After saving the recording, it can be embedded in a Moodle course or a Mahara page.
