An IT Integration wall is a great way to support student use of technology for learning in the classroom. There are many different approaches that you can take. One approach is to create a poster of Just Right resources for your grade/students. Here’s an example from a grade 2 classroom.
The teachers included instructions of how to use Dropbox, as well as QR codes to resources appropriate for this unit. This space can be aa big, or as small as you want it to be, and you can involve student “experts” in creating it, especially at older grades. I’m also creating tutorials for some classes/grades, and those types of resources can be incorporated into the space.
If you’re looking for resources to create QR codes, here are some resources.
