These little codes are popping up all over town. You can scan them with the bar-code reader on your phone while at restaurants to get their menu and reviews. You can use them in place of your boarding pass printout at the airport and other businesses are using them as well.
When you scan a QR-Code you get information sent to your phone. Schools should be harnessing this power. You can send both text and URL's, so you can really send ANY information that you can put on the internet.
Teachers could display a QR-Code at the end of class with links to the homework and class documents, or during class with links to discussion questions and group work. The possibilities are as endless as your creativity in adding student content to the web...oh, and your school's cell phone policy.
