These two Chrome extensions improve the way students handle two tabs at the same time. If they are in the process of researching and taking notes with an open Google Doc and an online information source, this is perfect!
Cite This For Me: Web Citer to be sure to remember to cite the sites used!
When students finish with an information source, simply glue the screens back together. The extension will make the tab on the left the main screen.
One search for Tab Scissors in the Chrome Web Store will give you both extensions!
