I created a QR research center in order to showcase one country a month in my classroom. Students scan codes and watch short videos on different aspects of different countries, listen to national anthems, see the different flags, and much more. It is a great way to promote world interest, independent research, and a variety of other skills indoor classrooms. Students love it! They even work on presentations of what they have learned to share with the class ON THEIR OWN! It's wonderful.
