Skitch is a way to gather information from the screen. It is very versatile tool. After collecting the page image you can write notes on the page.
This page came from Projects by Jen
http://projectsbyjen.com Then I found her section on Guess the Wordle. In her post she gave some wonderful reasons to use wordle in the classroom.
The idea that resonated with me was showing key words. The connection I made was in using it to take notes and to do research. Using Skitch I was able to write on the page about my connections. For students as they read articles they could take notes make connections. The tool is easy to use.
