In my class, I really try to push the concept of Growth Mindset. Earlier in the year I created some posters of famous people with some motivational quotes to put up around the room. To do this, I used Google Slides. I knew that the students were likely to ask who the various people in the posters were, so I created QR codes and put them in the bottom corner of each poster. The QR codes link to some information on the web explaining who the person is. QR codes are really easy to create. I use the site qrstuff.com, and once you have the information that you want to link to, the process is fairly straight forward when you are on the site to make your QR code. To scan the QR codes, I use the app i-nigma on my mobile device. Try it yourself on any of the posters in this post.
