I love them because it makes it so much easier for a student to find the exact article/website/video I want them to find. They don't have to type in a long website (and inevitably misspell some of the nonsense words) and they don't have to go to Google, search for XYZ, click link 47 on page 112... You get the idea. I find them to be faster than having them go to my classroom website for a link. They are easy and instant -- perfect for using in class!
Tonight, I was working on a CER writing assignment for my Biology class on Interactions in Communities. Part of the process is gathering evidence, so I started searching for articles, websites, or videos they could use to gather the evidence. Then I started thinking about how slim my chances of booking a computer lab for class on short notice would be... Then I thought about how lame the articles are without the stunning photos... Then I thought about the whining and groaning when I give them the articles that don't have pictures...
There has to be a better way!
Dramatics aside, this is the situation I've been in often so far this year. With a school of 3,000 students, computer use for an entire class is at a premium. I sometimes come up with ideas last minute and don't have the ability to get a computer lab last minute. Why not use the technology students already have in their pockets?
For the CER writing assignment, I decided to provide students with both the written form of the articles and the links to the online versions. I even included a few codes to videos on the topic. Since they are sharing a set of articles as a group, every person will have something to do, regardless of whether they have a smartphone. Those that do have a phone can easily share with their partner.
Utilizing smart phone technology has opened up so many possibilities in my classroom without the hassle of having to book technology.
My favorite ways to use QR codes in class:
1. Self-Paced Videos:
Lots of teachers (myself included) like to use a variety of videos to supplement instruction, many times providing a list of questions to answer while watching the video. We all know that students work at different paces. Why not give them a QR code to the video, have them use their headphones, and work through the video at their own pace!2. Tutorials:
For math-heavy chemistry units, I make tutorials on my SmartBoard for explanations on how to solve some of the trickier problems. Put a QR code next to tricky concepts on a study guide to provide easy access to remediation and help -- whether its linked to your own tutorial or another you find online.3. Stations Labs:
It can be tricky to incorporate variety in labs during the macrobiology units like Ecology. Try creating stations where students gather information from a variety of sources -- articles, websites, videos, text books -- and have them answer questions, create an illustration or graphic organizer at the end. You can use the QR code to provide links to any (or all) of the resources. I usually have some of them printed out, and others only online.4. Provide Visuals:
There are so many articles online that include stunning photography. I typically cut these out of my copies for class to save paper and because the pictures don't look that great being photo copied! At the bottom of the articles, I provide a QR code to the online version with a blurb saying "For the full article and awesome pictures, follow the link!"These are my very basic ways of incorporating QR codes into my classroom. There are lots of teachers out there who go way above and beyond what I have just started to discover. I do not use them on everything -- although I probably could! -- but I think they provide a great way to bring technology into the classroom, give students some control over their learning and pacing, and to differentiate and "spice up" what would typically be less engaging.
