Simple instructions that history teachers will love for setting up a QR code scavenger hunt. My favorite app is i-Nigma for scanning qr codes -it just works.
" A QR-Code Treasure Hunt is a fun, simple way to get students using their mobile devices to continue learning outside of lesson time. Here's how we set one up at the International School of Toulouse with some guidance on how to do the same with your own students using the QR Treasure Hunt Generator at ClassTools.net."
I've uploaded the portfolio assignment that I use for my one semester 8th grade keyboarding class. It includes movie making, self creation of rubrics, MLA paper writing, memos, block letters, blogging, and an efolio component along with QR Codes. I wanted to share this but also was testing the functionality of the site for sharing resources. Hope you'll share. (Note: KS3 in the UK means grades 7-9 - the site will be adding US grade levels soon.)
A very useful livebinder by some teachers on QR codes in the elementary school with information and guides. I've found this is pretty updated even though the first page has a description from 2010. Very useful if you want to use them in your classroom or library at the elementary level.
