JING is a very practical tool to take screen shots, to capture short videos and to share them with others ot to use them in your documents. I highly recommend you watch the instructional video(s) right after you download the application.
I use JING in a number of ways. For example, while preparing infographics or powerpoint presentations , it is really helpful. Below is an example how I used it in my writing class while we were brainstorming on how to narrow down the topic to provide background information. I am sure you can come up with several other ways to use JING 🙂
